Thanks a lot！！ could you please tell me the version of Opencv you are using in this project ,cause when I run the code with opencv4.5.4 ,it turns out like this:

INFO: Ground removed in 64543 us INFO: Ground removed in 29 us60 INFO: image based labeling took: 3363 us INFO: labels image sent to clients in: 6 us INFO: prepared clusters in: 4033 us terminate called after throwing an instance of 'cv::Exception' what(): OpenCV(4.5.4) /home/zp/Downloads/opencv-4.5.4/modules/imgproc/src/convhull.cpp:143: error: (-215:Assertion failed) total >= 0 && (depth == CV_32F || depth == CV_32S) in function 'convexHull'
