If anyone has encountered this issue and has any tips on how to solve it, that would be helpful. Stereolabs even has a tutorial for using Kalibr with their ZED Mini camera which uses the same shutter technology (AFAIK) as the ZED 2. There is another person who encountered - seemingly - the same issue but there are unfortunately no tips on how to fix this. I also tried just calibrating one of the two cameras with the pinhole-radtan-rs (rolling shutter model), but that also failed because of an "index out of bounds" without a stacktrace somewhere in the codebase, because it was already late I did not investigate this further. I also tried calibrating it with a resolution of 1080p (lower horizontal and vertical FOV) with the pinhole-radtan model, but that also failed. I tried calibrating it with a 720p resolution trying both the pinhole-radtan and pinhole-equi models. However, I wanted to calibrate a ZED 2 but the process always fails to converge (re-projection error increases from initally slightly less than 0.5 to ~0.55-0.6). I recently went through all the steps of obtaining the intrinsic IMU parameters, calibrating a D435, and calibrating the extrinsic parameters between the IMU and D435, so I know that it works. I was wondering if anyone here was able to calibrate the intrinsics of a ZED 2 camera with the Kalibr toolbox. Follow the ROS support guidelines (link is in the sidebar).Īlso see reddit's rules and the ROS etiquette.Įdit: In case anyone else has this issue: using an A4-sized target and moving the camera slower than you would normally do "solved" it for me more or less.
