Camera Intrinsics Parameter #3

Open ooops1234 opened 2 years ago

ooops1234 commented 2 years ago

Hi, I have a question about the camera parameter. In the UGV_imu_cam.txt/Handheld_imu_cam.txt calibration file, are the four values in distortion coefficient [p1,p2,k1,p2] respectively? If so, the Distortion coefficient values seem very large. Or maybe my understand is wrong. How should we use the distortion coefficient parameters? Thanks for your time!

Hi there, Thanks for the issue! I'll double-check the calibration data to see if the error is within reasonable range. We use kalibr for the imu/cam calibration, so it is perhaps useful to see how the results are defined in that package.
