Package Overview

The ROS DVS package provides C++ drivers for the Dynamic Vision Sensors (DVS/DAVIS). Even if you do not have a DAVS or DAVIS device, you can still use this driver to read pre-recorded event data files (see the example below). The package also provides a calibration tool for both intrinsic and stereo calibration. To find out more about event cameras, visit the website of the Institute of Neuroinformatics. The package is based on libcaer.

Driver Installation

NOTE: substitute any mention of kinetic in the following instruction with the name of your current ROS distribution.

Install ROS dependencies:

$ sudo apt-get install ros-kinetic-camera-info-manager
$ sudo apt-get install ros-kinetic-image-view

Install libcaer (add required repositories as per iniVation documentation first):

$ sudo apt-get install libcaer-dev

Install catkin tools:

$ sudo apt-get install python-catkin-tools

Create a catkin workspace (if you have not done it yet):

$ cd
$ mkdir -p catkin_ws/src
$ cd catkin_ws
$ catkin config --init --mkdirs --extend /opt/ros/kinetic --merge-devel --cmake-args -DCMAKE_BUILD_TYPE=Release

Clone the catkin_simple package (https://github.com/catkin/catkin_simple), which will be used to build the DVS/DAVIS driver packages:

$ cd ~/catkin_ws/src
$ git clone https://github.com/catkin/catkin_simple.git

Clone this repository:

$ cd ~/catkin_ws/src
$ git clone https://github.com/uzh-rpg/rpg_dvs_ros.git

Build the packages:

$ catkin build dvs_ros_driver (if you are using the DVS128)
$ catkin build davis_ros_driver (if you are using the DAVIS)
$ catkin build dvxplorer_ros_driver (if you are using the DVXplorer)

You can test the installation by running a provided launch file. It starts the driver (DVS or DAVIS) and the renderer (an image viewer).
1. First, build the renderer:
  - $ catkin build dvs_renderer
2. Set up the environment:
  - $ source ~/catkin_ws/devel/setup.bash or if you use the zsh shell instead $ source ~/catkin_ws/devel/setup.zsh
3. Then, launch the example:
  - $ roslaunch dvs_renderer dvs_mono.launch (if you are using the DVS128)
  - $ roslaunch dvs_renderer davis_mono.launch (if you are using the DAVIS)
  - $ roslaunch dvs_renderer dvxplorer_mono.launch (if you are using the DVXplorer) You should get an image like this (in case of the DAVIS):
If you do not have a DAVIS, you can still use this driver to read recorded files, such as those of The Event Camera Dataset and Simulator. Example:
1. Download a squence of the dataset, such as slider_depth.bag
2. Open a terminal and launch the roscore:
- $ roscore
1. In another terminal, play the bag:
- $ rosbag play -l path-to-file/slider_depth.bag
1. In another terminal, launch the DVS/DAVIS renderer:
- $ roslaunch dvs_renderer renderer_mono.launch You should see a movie with images like this:
Optional: in the case of a live stream from the DAVIS (i.e., not a recorded file) you may adjust the DVS/DAVIS parameters to your needs using the dynamic reconfigure GUI. Run
- $ rosrun rqt_reconfigure rqt_reconfigure and a window will appear. Select the davis_ros_driver (on the left panel) and you should get the following GUI that allows you to modify the parameters of the sensor.

A guide on how to modify the parameters in the bottom half of the GUI (biases) can be found here: https://inivation.github.io/inivation-docs/Advanced%20configurations/User_guide_-_Biasing.html

Calibration

For intrinsic or stereo calibration of the DVS and DAVIS, please have a look at the following document.

Troubleshooting

New dvs_msgs format

If you recorded rosbags with a previous version of this package, they must be migrated. The format for the timestamps changed from uint64 to rostime. To convert an "old" bag file, use: $ rosbag fix old.bag new.bag.

Compiling error

On Ubuntu 14.04 with GCC 4.8, you will receive an error about missing file (stdatomic.h). This is a problem related to GCC 4.8 and can be resolved by updating to version 4.9:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.9 g++-4.9
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-4.9 60 --slave /usr/bin/g++ g++ /usr/bin/g++-4.9

rpg_dvs_ros's Issues

DVS128 stereo Sync with ROS

Hello,

I hope I can find some help here, as it is dvs-ROS related.
I'm working with a stereo setup, under ROS kinetic, with two dvs128.
As described here , the OUT pin of the Master camera is connected to the IN pin of the Slave camera.

After that, I guessed the software configration was made in the stereo.launch file, from the dvs_ros_driver package. So I set to 'true' the parameter called 'master', for the Master camera (and respectively, to 'false' for the Slave camera).

Unfortunately, I don't succeed to synchronize the two camera, as the bottom LED of the Slave still remains ON.
I sure can do it with jAER, but the modifications I make in the ROS .launch don't seem to take effect.

Is there something I am missing?

Thanks, for your help,

Kevin.

Calibration Pattern

Hello,
i have a DVS128 from inilabs.
Is it possible to acquire a calibration pattern somewhere or do i have to build one myself ?

Compilation error on catkin build

ANy ideas? newbie into all of this, a bit lost.

Autoexposure issue with DAVIS346

Hello,

I was using dvs_renderer to record ROS bags with a DAVIS346 device. Autoexposure was enabled by setting autoexposure_enabled: true in the configuration .yaml file. At first everything seemed to work fine, but then exposure started to oscillate between two values and never recovered. Is there anything that can be done to avoid this?

Thank you,
Antea

Compiling error of the dvs_ros_driver

Hi guys, I'm trying to compile the rpg_dvs_ros package these day. When I compiled the dvs_ros_driver, there is a error just like below:

/opt/ros/indigo/lib/libcamera_calibration_parsers.so: undefined reference to `YAML::detail::node_data::convert_to_map(boost::shared_ptrYAML::detail::memory_holder)'

How can I fix this bug? thanks~~

IMU units for acceleration?

I wonder if it has been checked that the units for the DAVIS IMU acceleration are really correct? I am seeing in one recording about -0.9 m/s^2 for y component, which should be -9.8m/s^2 or about -1g. This comes up in developing a native-java ROS bag reader for jaer, where I need to convert back from ros IMU units to internal jAER units, which are in g for acceleration and deg/s for gyro rotation (and are the native units for the invensense IMU, which is why these units were unfortunately used to begin with).

Does the ROS IMU acceleration have gravity component removed from y component? This wouldn't make too much sense but could it be why y is too small? It doesn't really make sense, since y component is always the one with significant negative component, and corresponds to how the camera was mounted in the recording.
I haven't looked at the source code yet, sorry for this laziness.

compiling error: dvs_ros_driver::DVS_ROS_DriverConfig

in rpg_dvs_ros/dvs_ros_driver/include/dvs_ros_driver/driver.h, it include <dvs_ros_driver/DVS_ROS_DriverConfig.h>, which i can not find in source code...where can i get it?

Translation of threshold biasing settings to actual value

The threshold of the DVS for event generation is determined by the setting of the biasing currents in the circuit. In this driver, the same is achieved by changing the sliders corresponding to ONBn and OFFBn (both course and fine). Is there a way to translate the numbers in the slider setting to the actual value of threshold for use in a reconstruction algorithm?

Suppose events happen at t+1, I can naively reconstruct the image at t+1 by adding threshold*event_polarity to the Frame image at t. For this I would need to know the correspondence between the slider setting and the threshold value.

merge dvs_ros_driver and davis_ros_driver

Much code overlaps since switching to libcaer, thus it would make sense to merge them into a single package.

TimeStamp Reset Problem.

Hi,

After I using rosbag record to recording my Davis data, I used dvs_write_file( extract_davis_bag.py) to obtain internal data. However, I notice that time stamps in the file event.txt did not be reset to 0.0000. Is there something wrong with my operation or some details have been missed through my process?

BW,

Thank you.

Stereo Calibration with DVS and RGB camera

I would like to make a stereo pair with a dvs128 and a standart rgb camera. would this be possible with this package?
camera_dvs.launch to me seems to do this. is this correct?
if not what would be a god way to do it? i was thinking about putting my led grid on a circle pattern so the dvs and the rgb camera would see the same points. I also thought of replacing the find checkboardcorners so the rgb camera would find the leds.
any suggestions?
Thanks in advance.

Bug when using grayscale display_method

When selecting grayscale display_method, the output image is constantly flashing, most likely due to collision of the image publishers in both images and events callbacks.
In renderer.cpp, the flag used_last_image_ is never set to true in the case of grayscale, so lines 150-151 could instead be this, in a similar way as it is done in the case of red-blue display_method.

Downgrade DAVIS revision

Hi,

Is there any method to downgrade DAVIS revision from 16 to 9912? or specifically 9912.

I had reflashed DAVIS device from 9912 to 16 for executing jAER toolkit, but this ROS package requires 16 revision.

Thanks.

DAVIS build broken

Hi,

It looks like after adding DAVIS_CONFIG_DVS_FILTER_..... the build is broken. I pulled the latest of the libcaer, however, that did not help. I went back to a few commits and it works fine. I did not validate exactly which step it broke but I checkout 4c1e1ee commit and it seems to be working fine. From the code, it looks like the changes were due to support for miniDVS so I went to that commit. Please fix or let us know if there is an extra step I might be missed to get over this issue with the latest commit.

Best,
Snehesh

branch master: [davis_ros_driver-1] process has died

Recent changes after install on new computer with Ubuntu 16.04 with ROS Kinetic causes the Davis driver to die right upon starting dvs_renderer using:

roslaunch dvs_renderer davis_mono_events_only.launch
or
roslaunch dvs_renderer davis_mono.launch

Yet: davis_mono_nodelet.launch does work though

aps_enabled has no effect

Hi all,

I'm using a davis240c and trying to run it with the parameter aps_enabled: false, but apparently it has no effect and the driver enables the image acquisition.
I'm pretty sure the file is loaded correctly as when I modify other parameters (e.g. frame_delay) of the .yaml file they do have the desired effect.
Any idea why?

thank you in advance

Issue with loading events from ROS bag file into MATLAB ROS Toolbox

Hi,

We have ROS bag files with IMU, image, and events data from DAVIS 240B. Everything else loads file with rosbag function. However, when trying to decode /dvs/events messages the toolbox is not able to handle it as it seems ros bag stores it in custom data type. We used the dvs_msg folder with rosgenmsg function in the toolbox to generate custom data support. However, this step does not seem to work due to the EventArrayRule.bmr file defined in the package.xml. MATLAB ROS toolbox is not able to handle this. Can you please advise how we might be able to get this hurdle?

Calibration Check Problem

Hi,

I noticed that I can simply use the APS frame to calibrate my DAVIS camera, however when I use camera_calibration package to calibrate my device. The whole process works fine until I try to using camerachecker.py to check my intrinsic parameters, the topic from image_raw and camera_info cannot synchronize.
Has anyone else come across this problem before, is there any solution for this specific problem? Or, is there another way else to help me verify the intrinsic and maybe extrinsic parameters?

Thanks

No instructions for recording data

I was able to get the packages running according to the instructions in the README. However, I couldn't find instructions on how to record the event, image and IMU data the DAVIS into a file. Could someone please tell how it is done?

change streaming rate

hi, i use GUI to modify the parameters .
No matter how I change the streaming rate, the actual frequency will not exceed 100 HZ

rostopic hz /dvs_rendering
subscribed to [/dvs_rendering]
average rate: 99.925
min: 0.000s max: 0.022s std dev: 0.00625s window: 95
average rate: 99.971
min: 0.000s max: 0.022s std dev: 0.00671s window: 195

How can I make the frequency greater than 100hz, thanks!

Mono Calibration on Ubuntu 16.04 with ros kinetic (OpenCV 3.1.0)

Hello DVS-Team,

I compiled the repo packages on Ubuntu 16.04 with ros kinetic (OpenCV 3.1.0). I had to adjust the parameter order of the stereoCalibrate-function in the file "camera_dvs_calibration.cpp" and change the import of QWidget in the file "calib_widget.py" (from ...QtGui to ...QtWidgets) to remove all compilation errors and to get a running mono calibration (dvs_intrinsic.launch).

But as soon as the dvs_128 detects the calibration-pattern (5x5 LEDs) some nodes die. It says:

OpenCV-Exception:
The function/feature is not implemented (You should explicitly call mapHost/unmapHost methods for ogl::Buffer object) in getMat_, file /tmp/binarydeb/ros-kinetic-opencv3-3.1.0/modules/core/src/matrix.cpp, line 1225

Ros-Error:
[roslaunch][ERROR] 2016-12-01 16:23:43,939: [dvs_calibration-4] process has died [pid 7488, exit code -6, cmd /home/fzi_pk/catkin_ws/devel/lib/dvs_calibration/mono events:=/dvs/events camera_info:=/dvs/camera_info set_camera_info:=/dvs/set_camera_info __name:=dvs_calibration __log:=/home/fzi_pk/.ros/log/184a092e-b7da-11e6-8d64-34e6ad58853b/dvs_calibration-4.log].

As for now we got stuck in debugging and probably going back to 14.04 with indigo but it would be nice to be able to use kinetic (+OpenCV 3). SO if you have some advises, would be great. Thank you very much.

Best Regards
Philip Keller

Incomplete instructions

First, for novices, it would be good to initially reference http://wiki.ros.org/kinetic/Installation/Ubuntu to know how to "Setup your sources.list" and "Set up your keys", and I assume I need to "Initialize rosdep"

Furthermore, step 8 appears incomplete; more detailed instructions would greatly benefit novices like myself.

"Only a udev rule is needed to run the DVS driver. An installation script is provided in the package libcaer_catkin.
$ roscd libcaer_catkin' (need to source your setup.bash file first, or just do $ cd libcaer_catkin) $ sudo ./install.sh`
"

What exactly do I need to do for the udev rule? When it references the installation script in libcaer_catkin, is that a prerequisite for roscd? I also got "No command 'roscd' found"; is roscd a typo? Which setup.bash file is sourced? Am I not supposed to worry about that if I do cd ibcaer_catkin? That doesn't seem to help.
Bottom line, I'm confused. Any help/advice would be appreciated. Thank you.

Error using DAVIS driver as nodelet

The DAVIS ROS driver currently clears the event array within the message immediately after publishing. This seems to cause problems when the driver is run as a nodelet as the subscriber receives a pointer to the original message, which now has an empty event array. Storing the event array in a separate variable which is copied into the message and then cleared seems to resolve the issue.

Unable to install libcaer

Hi,
Thank you for the wonderful ROS DVS packages!
I'm using ROS Kinetic on Ubuntu 16.04.7. libusb is installed, but I'm unable to install libcaer. According to the latest readme, I'm running,

sudo apt-get install libcaer-dev

But I get an error saying,

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package libcaer-dev

I looked up the official iniVation documentation for installing libcaer. it asked me to do two extra steps:

$ sudo add-apt-repository ppa:inivation-ppa/inivation
$ sudo apt-get update
$ sudo apt-get install libcaer-dev

I did this too, but it still gives the same error. Could you kindly advise me on what might be going wrong?
Thank you,
Abhinav

Error when building davis_ros_driver

I'm using Ubuntu 14.04 with gcc 4.9 and I'm getting exactly the same issue as here: #23

However, even if I ran catkin config --merge-devel before catkin build davis_ros_driver as it was advised I still having the same problem.
Has anyone any idea of what I can try?

Using event messages in real time

I would like to use the events of the DAVIS sensor for processing in real real time. Can someone please point me towards how I can go about this?
Thanks

What's the problem?

Missing include guard

seems like an include guard is missing in the following file?

[build] Note: Workspace packages have changed, please re-source setup files to use them.

I saw an old issue #33 I can see that the changes have been made. I am not sure if the package is built properly.

I am using Ubuntu 16.04 with Kinetic.

Thanks

Hi, I am trying to finish the driver installation. Works great till Step 9. When I do catkin build dvs_renderer - it fails. Not really sure what to do next.

Thanks in advance!

undefined reference to `libusb_strerror'

I am having a compile error when building 'davis_ros_driver'

/media/captainjl/DATA/catkin_ws_dvs/devel/lib/libcaer.so: undefined reference to libusb_strerror'`

Does anyone know how to solve this?
I have installed the libusb as defined in the readme file.

eDVS support

Hi,

As far as I can tell, there is no ros wrapper for the eDVS. I was able to tweak the DVS128 driver to work with eDVS since libcaer also wraps the eDVS in a similar way than the DVS128 (see the diff).

Would you be interested in a cleaned-up pull request, and if yes, what would be the best way to integrate the eDVS properly?

Cheers,
Jacques

Frames and Events only

Hello,

Thank you for this great package! I was playing around with my DAVIS camera and this package and I was having trouble trying to get frames and accumulated_events running in the gui. Only the dvs_renderer seems to be working. Any suggestions?

Thanks
Harsh

clarification: EventMsg timestamp meaning

Sorry for this newbie question, but it's related to trying to develop a jAER player for these great rosbag files.

Does the line 576 in driver.cpp https://github.com/uzh-rpg/rpg_dvs_ros/blob/master/davis_ros_driver/src/driver.cpp

e.ts = reset_time_
                                + ros::Duration().fromNSec(caerPolarityEventGetTimestamp64(event, polarity) * 1000);

mean that the event time stamp from the libcaer/ros driver event is the absolute time (since 1970) in ROS seconds? I.e. it is not the raw camera timestamp in us since some arbitrary timestamp reset?

I see that reset_time_ is assigned as
reset_time_ = ros::Time::now();

Presuming that the camera timestamps are reset around the time that reset_time_ is assigned, it would mean the the event timestamps are approximately the actual world time, except for crystal oscillator frequency inaccuracy and drift. Is this correct?

Apologies if this question has already been asked and answered.

Issue for images

How to read rosbag with customised topic names

I try to read a rosbag recorded from davis 346 camera.

The topics in the rosbag are like :

/davis/left/events
/davis/left/image_raw
/davis/left/imu
/davis/right/events
/davis/right/image_raw
/davis/right/imu

I have modified /dvs_left/events in renderer_mono.launch and renderer_stereo.launch to /davis/left/events and also image_raw topics , however, when I launched roslaunch with the launch file, I have nothing displayed on the screen.
And the process dvs_renderer is still launched with /dvs_left/events

catkinws/devel/lib/dvs_renderer/dvs_renderer events:=/dvs_left/events dvs_rendering:=dvs_rendering_left __name:=dvs_renderer_left _

Is there anything wrong with my procedure?

Thanks for you attention.

The rendering of accumulated event edges crashes after a few seconds

A session to render the events fo the DAVIS is started with the command roslaunch dvs_renderer davis_mono.launch.

The command below renders edges for a few seconds renders an edge map but then crashes
rosrun image_view image_view image:=/dvs_accumulated_events_edges

Followings its crash, the dvs_renderer package also crashes. I assumed it was a processing problem and hence tried reducing the max_events parameter in the /davis_ros_driver to 100 and suppressed the OFF events. However the problem still persists

catkin_make install fails on dvs_renderer

When running the following excerpt (please note that the packages dvs_msgs and dvs_renderer are pulled in transitively by scanning the dependencies of my packages) from my Dockerfile:

[...]
RUN mkdir -p catkin_ws/src
RUN /bin/bash --login -c "cd catkin_ws \
    && source /opt/ros/kinetic/setup.bash \
    && source /usr/share/gazebo/setup.sh \
    && catkin_init_workspace src \
    && catkin_make"
# copy catkin packages and install
COPY catkin_src catkin_ws/src
RUN /bin/bash --login -c "cd catkin_ws \
    && source /opt/ros/kinetic/setup.bash \

    && source devel/setup.bash \
    && catkin_make clean \
    && catkin_make install --only-pkg-with-deps lwa4p_ball_balancing ros_music_adapter"
[...]

the last command (catkin_make install ...) fails with the error message:

See below for the full build log.

Apparently, the file "nodelet_stereo.launch" can not be found in the directory. Indeed, it is not located in the root folder of the dvs_renderer package, but in a subfolder called "launch":

.

    ├── renderer.cpp
    ├── renderer_node.cpp
    └── renderer_nodelet.cpp

Hereby, the problematic install order originates from CMakeLists.txt, which addresses the launch files without prefix:

[...]
install(FILES dvs_renderer_nodelet.xml nodelet_stereo.launch nodelet_mono.launch
  DESTINATION ${CATKIN_PACKAGE_SHARE_DESTINATION}
)

As this approach appears to work on other systems, I figure this might be an user error. I am using Ubuntu 16.04 (docker image) with a fresh ROS install (I can provide a package list if desired).

Issue with using DAVIS events from ROS bag in MATLAB ROS toolbox

Hi,

We have ROS bag files with IMU, image, and events data in one bag file from DAVIS 240B. Everything else loads fine with rosbag function in the MATLAB toolbox. However, when trying to decode /dvs/events messages the toolbox is not able to handle it as it seems ros bag stores it in custom data type. We used the dvs_msg folder with rosgenmsg function in the toolbox to generate custom data support. However, this step does not seem to work due to the EventArrayRule.bmr file defined in the package.xml. MATLAB ROS toolbox is not able to handle this. Can you please advise how we might be able to get this hurdle? The goal is to be able to read the events in MATLAB via this ROS toolbox.

Best,

In developing the jAER rosbag reader, I notice in one recording from an advanced Davis346 sensor that in the middle of ROS messages holding topic "/dvs/events" there are events with negative delta times around 99ms. They occur in the middle of messages. Samples below. Does anyone know if this might be a consequence of the fact that the rosbag might not be written in strict monotonic Davis timestamp order, or more likely from a flaky USB connection?

If I discard these events, then the next event is apparently always newer. I.e. it doesn't appear that there is a jump backwards in time of 99ms of the entire stream (however, to be confirmed).

Failed to open device, no matching device could be found opened.

Hi,

I have installed DVS_ros driver according to Readme.txt, but when I run "roslaunch dvs_renderer dvs_mono.launch", terminal shows that "failed to open device, no matching device could be found opened. "

Thanks,
Joey
