【备忘】cv2.rectangle TypeError

img = cv.rectangle( img, pt1, pt2, color[, thickness[, lineType[, shift]]] )
img = cv.rectangle( img, rec, color[, thickness[, lineType[, shift]]] )

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
