Hello, I am using deepstream 6 to do multiple car tracking detection in a parking lot. I would like to know how to add dewarp to the pipeline and how to generate the calibration matrix. Can you help me?

To get the correct distortion coefficients you need to use the following calibration method of opencv : <a href="https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdocs.opencv.org%2F2.4.13.7%2Fdoc%2Ftutorials%2Fcalib3d%2Fcamera_calibration%2Fcamera_calibration.html&data=05%7C01%7Csrathi%40nvidia.com%7Ceb422ffb6d0646de029508da85c47908%7C43083d15727340c1b7db39efd9ccc17a%7C0%7C0%7C637969376148452994%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=VVq%2BLw%2B6UgSSGtrrBd4fHvsbw%2BrXB%2BcPYXsIfjMClrA%3D&reserved=0">https://docs.opencv.org/2.4.13.7/doc/tutorials/calib3d/camera_calibration/camera_calibration.html This will give you focal length(fx, fy), principal point(cx, cy) and 5 distortion coefficients :…

Thanks,

About the config_dewarper_perspective.txt file, how do I find the distortion values?
