hello guys,
Could someone please share the steps on how to get execute this project?
I have tried so many ways by cloning this repo and trying to run an example but it's not happening.
I would indeed be very thankful if someone could please help me on how to go about detection of april tags using this repo.
from apriltags_ros.
The long way would be to create a catkin workspace, clone the repo, catkin_make it.
Otherwise, simply
sudo apt-get install ros-indigo-apriltags-ros
This will pull the version from the ubuntu ppa. Take note that the version there doesn't contain the launch file (you can copy it from the repo here).

@23pointsNorth, thanks!
Sorry it took so long, but I finally tried to install it. I wasn't able to install using catkin_make (it said that needed some dependencies on eigen, which I have btw).
Anyway, it worked with the apt-get.
I was trying to detect tags using the AprilTags on ROS, and I was actually able to detect them. However, when I check the topic /tag_detections_pose or the /tf, it always gives translation=[0,0,0], rotation=[0,0,0,1].
Is AprilTags supposed to give me at least rotation or am I missing something?

Do you have the camera calibrated? It requires information to be published on the CameraInfo topic.
from apriltags_ros.
@23pointsNorth You were right, I didn't setup the calibration file correctly and it was giving weird outputs.
BTW, from your experience what would be the optimal setup for using apriltags?
I am currently using in an i7-4600U CPU (2.10Ghz - Turbo 3.3GHz) with Hyperthreading disabled. The image camera source is in 1280x720.
When running rostopic hz /tag_detections_pose, I get:
average rate: 6.522
min: 0.109s max: 0.335s std dev: 0.02411s window: 1025
This means that I am getting about 6.5Hz of output refresh rate. Is this within expected? What would you recommend as ideal setup?
