运行检测程序报错

Traceback (most recent call last):

cv2.error: OpenCV(4.6.0) :-1: error: (-5:Bad argument) in function 'line'

>  - Can't parse 'pt1'. Sequence item with index 0 has a wrong type

原因：类型出错

解决办法：

第一种：将报错语句中所有能改类型的值全加上int强制转成整型

第二句更正为：

cv2.line(img, (int(corners_int[0, 0]), int(corners_int[0, 1])), (int(corners_int[3, 0]), int(corners_int[3, 1])), (255, 255, 0), 2)

第二种：opencv-python版本过高导致，降低版本

参考别的博主，从4.6.0降下来，亲测该版本可行

pip install opencv-python==4.5.1.48
