Opencv针式仪表盘识别.py

不能用 这个就是骗积分的，我读取图片都出现not enough values to unpack (expected 3, got 2) 不建议下载

你好，下载了程序，修改了img_path 报错，Traceback (most recent call last): File "C:/Users/lenovo/Desktop/DashBoard.py", line 404, in <module> main() File "C:/Users/lenovo/Desktop/DashBoard.py", line 400, in main detection_contour() File "C:/Users/lenovo/Desktop/DashBoard.py", line 244, in detection_contour binary, contours, hierarchy = cv2.findContours(binary, cv2.RETR_TREE, cv2.CHAIN_APPROX_SIMPLE) ValueError: not enough values to unpack (expected 3, got 2)

不知道能不能用
