How to save wavepoints rosparam set not working Theorical Python use in ROS. But I don't know what to do with this data in order to use the stereo vision. how to get linear and angular velocity from zed camera odometry. Running the calibration with the -no-service-check parameter works and results a /tmp/ file which contains the ost.txt text file with the calibration parameters. What is the proper way to do camera calibration with the usb_cam driver? Download the factory-calibration file for your ZED camera with the following command: bobdesktop:/isaac engine/build/scripts/downloadzedcalibration.sh -s Tip Alternatively, you can use the ZED Explorer tool to download a factory-calibration file.I know I can use the the -no-service-check parameter and it works afterwards, but it won't commit then the calibration parameters to cameras. You should use directly stereoCalibrate instead of calling twice CalibrateCamera2 even if the ouputs should be quite similar. Also, there is a C++ sample stereocalib.cpp for stereo calibration. Waiting for service /stereo/right/set_camera_info. Comments To debug, you should try to print the shape of the different matrices. Then I want to calibrate them with the following command: rosrun camera_calibration cameracalibrator.py -size 9x7 -square 0.0053 right:=/stereo/right/image_raw left:=/stereo/left/image_raw left_camera:=/stereo/left right_camera:=/stereo/right -approximate=0.005Īnd it generates the following errors: Waiting for service /stereo/left/set_camera_info. I start the cameras with the following launch file: True, the camera driver is publishing camera calibration parameters in camerainfo but file format is. I use 2 USB cameras for stereo vision with the usb_cam driver in ROS Groovy and I would like to calibrate them with the camera_calibration package. To start the calibration you will need to load the image topics that will be calibrated: rosrun cameracalibration cameracalibrator.py -approximate 0.1 -size 8å -square 0.
