Python Opencv 错误记录

本文记录在使用Python中的Opencv库的过程中踩过的坑，以史为鉴。

cv2.rectangle

问题

• {TypeError}an integer is required (got type tuple)
• {TypeError}argument for rectangle() given by name (‘color’) and position (3)
• {TypeError}argument for rectangle() given by name (‘thickness’) and position (4)
• {TypeError}an integer is required (got type tuple)

解决办法

• 坐标pt1,pt2需要是整型
• img=np.ascontiguousarray(img)，然后调用rectangle
