这个错误通常是由于传递给函数的参数不正确引起的。请检查你传递给cv2.polylines()函数的参数是否正确。
其中一个可能的原因是你传递给函数的点集不正确,可能包含无效值或者点的数量不正确。请确保传递给函数的点集是正确的,并且每个点都是一个有效的坐标值。
另外,还有一些其他的可能导致这个错误的原因,比如你传递给函数的线宽度不正确或者你传递给函数的颜色不是一个有效的RGB或BGR值。请检查你传递给函数的所有参数,并确保它们都是正确的。
如果你仍然无法解决这个问题,请提供更多的上下文和代码片段,以便更好地理解问题并提供帮助。

cv2.error: OpenCV(4.5.5) :-1: error: (-5:Bad argument) in function 'flip'
This error occurs when the flip() function in OpenCV is called with an incorrect or invalid argument. The most common reason for this error is passing an image that has not been properly loaded or has been corrupted.
To resolve this error, make sure that the image you are passing to the flip() function is a valid image and has been loaded correctly using the imread() function in OpenCV. Additionally, check that the argument being passed to the flip() function is one of the allowed values (0, 1, or -1) for flipping the image horizontally, vertically, or both.
