Hi, the error when runs "run_get_weight_matrices.py". Please help, thank you very much!

File "run_get_weight_matrices.py", line 36, in main() File "run_get_weight_matrices.py", line 24, in main Gmat, Mmat = birdview.get_weights_and_masks(projected) File "/home/idriver/work/AVP/surround-view-system-introduction-master/surround_view/birdview.py", line 301, in get_weights_and_masks G0, M0 = utils.get_weight_mask_matrix(FI(front), LI(left)) File "/home/idriver/work/AVP/surround-view-system-introduction-master/surround_view/utils.py", line 114, in get_weight_mask_matrix distToB = cv2.pointPolygonTest(polyB, (x, y), True) cv2.error: OpenCV(4.5.5) :-1: error: (-5:Bad argument) in function 'pointPolygonTest'

Hi, since you are using OpenCV 4.5.5, which is a higher version than this repo (4.0.0), I guess the function cv2.pointPolygonTest() expects different types of arguments now. Maybe you can try cv2.pointPolygonTest(polyB, (int(x), int(y)), True) ?

老师您好，在照着您的建议修改之后，在surround_view\utils.py文件中出现了如下问题C = sorted(cnts, key=lambda x: cv2.contourArea(x), reverse=True)[0]IndexError: list index out of range，请问该如何解决？

你试试把 sorted(cnts, key=lambda x: cv2.contourArea(x), reverse=True) 结果打印出来，看看返回了一个什么。

请问您解决了吗。我目前也是遇到了这个错误
