Parameters
Usage
Some sample .launch files are provided in this package. The simplest way to launch the algorithm is by running the three main ROS nodes as follows:
roslaunch velo2cam_calibration laser_pattern.launch
roslaunch velo2cam_calibration stereo_pattern.launch
roslaunch velo2cam_calibration velo2cam_calibration.launch
Note: In order to test the algorithm with a proper ground truth, a simulator environment in Gazebo is provided here
Calibration target details
The following scheme shows the real size of the calibration target used by this algorithm. Measurements are given in centimeters (cm).
Note: Other size may be used for convenience. If so, please configure nodes parameters accordingly.
