Is Stereolabs still staffed? I have a problem in the process of using it, and I have sent 5 emails continuously for a week, but still no staff can help me solve it. The only reply is to ask me to ask questions in the current forum, but it has been two days, and there is still no reply from anyone.
I am using ZED mini, ZED SDK version 4.2.5. My computer uses cuda version 12.1, and the GPU is GTX1650. In the process of use, the accuracy has a serious problem. The test situation is as follows: 1, the actual distance is 0.873m, and the camera measurement depth is 0.711m. 2, the actual distance is 1.613m, and the depth measured by the camera is 1.268m. 3, the actual distance is 4.213m, and the depth measured by the camera is 3.32m. Note that all the above tests were performed after the ZED Calibration procedure. HD720, 15 frames, ULTRA mode was used for all tests. The actual distances were all measured by a laser range finder. You can see that the overall test results are low, and the error increases with distance. I would like to ask for your help, what is the cause of this situation? What’s the solution? My use scenario is an outdoor scene of about 10m. The camera is mainly used to collect data, and the resolution can only be used with HD720. In this regard, do you have better suggestions on camera Settings?
Not with Stereolabs, but I noted that your % error is (more or less) consistent at around 20%. This would suggest to me an issue with the comparison. Perhaps the pose (angles) of the camera aren’t aligned with your laser measurements. I think that might cause constant error percentages.
