hello,
I build the project , use "catkin_make -j1", but got:
-- +++ processing catkin package: 'uwb_calibration'
-- ==> add_subdirectory(uwb_calibration)
-- Using these message generators: gencpp;geneus;genlisp;gennodejs;genpy

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:

Makefile:2103: recipe for target 'cmake_check_build_system' failed
make: *** [cmake_check_build_system] Error 1
Invoking "make cmake_check_build_system" failed
Then in the slam_pp/CMakeLists.txt, I found:
find_library(Reflexxes_LIBRARIES flexxes ${PROJECT_SOURCE_DIR}/exLib/Reflexxes)
set(Relfexxes_INCLUDE_DIRS ${PROJECT_SOURCE_DIR}/exLib/Reflexxes/Reflexxes)
But not the folder
What can I do ? Thanks a lot.
The recent 1.8.2 firmware does not work well. Could you share your parameters and firmware version in your experiment?
There is an error in "./slam_pp/include/slam/uwb_node.hpp" @ line 309:
error:
} else if(m_uav_state.acceleration.linear.y<=-acceleration_linear_threshold_xy){
m_uav_state.acceleration.linear.y = -acceleration_linear_threshold_xy;
corrected
} else if(m_uav_state.acceleration.linear.x<=-acceleration_linear_threshold_xy){
m_uav_state.acceleration.linear.x = -acceleration_linear_threshold_xy;
Hi Li Jiaxin,
Thank you for publishing this interesting piece of code.
It looks like the common_msgs package is missing some of the custom messages namely:
NavigationState.msg
GPSVelocity.msg
MeasurementPosition.msg
MeasurementVelocity.msg
PixhawkCMD.msg
PixhawkServo.msg
MeasurementPosVel.msg
MaxDynamics.msg
Reference.msg
Mission.msg
MissionStatus.msg
PathPlanningStatus.msg
Waypoint.msg
and this stops me from building the code.
Would you please add them to the repo or give me directions if they are available somewhere?
thanks
Great work @lijx10 with the performance of your UAVs and thanks for making the localization code available.
I have been trying to understand the calibration part of your code. Is there is paper/documentation somewhere that could give me some hints? I understand that there is no unique solution to calibration of anchor positions if only the ranges between the anchors are known. So I have been trying to understand the following:
Thanks!
Hi Jiaxin Li
I am a Chinese too,I want to know Is there any other detail to understand those code?
Hi @lijx10, thanks for sharing your work to community. After read the reference paper: Accurate 3D Localization for MAV Swarms by UWB and IMU Fusion, when use imu's acc to serve as input to filter, i have a doubt.
As we all know, imu's acc is a measurement of imu body acc, in other words, it is local measurement, not a global measurement. The filter's variables x = [px, vx, abx, py, vy, aby, pz, vz, abz ]
are all global variables, in uwb's global frame, which is constructed by 6 uwb anchors in paper. Before use imu's acc, how to calculate the rotation between one imu frame attached on MAV and the uwb's global frame?
Any suggestion will be much appreciated! Thanks for your help :)
