Question

当我运行代码以使用网络摄像头进行对象检测时，收到以下错误消息：

 frame = cv2.rectangle(open_cv_stream, t1, br, color, 5)

TypeError：必须为整数（元组类型为元组）

capture = cv2.VideoCapture(0)
capture.set(cv2.CAP_PROP_FRAME_WIDTH, 1920)
capture.set(cv2.CAP_PROP_FRAME_HEIGHT, 1080)

while True:
    stime = time.time()
    ret, frame = capture.read()

    if ret:
        results = tfnet.return_predict(frame)

        for color, result in zip(colors, results):
            t1 = (result['topleft']['x'], result['topleft']['y'])
            br = (result['bottomright']['x'], result['bottomright'])
            label = result['label']
            confidence = result['confidence']
            text = '{}: {:.0f}%'.format(label,confidence * 100)
            frame = cv2.rectangle(frame, t1, br, color, 5)
            frame = cv2.putText(frame, text, t1, cv2.FONT_ITALIC, 1, (0,0,0),2)
        cv2.imshow('frame',frame)
        print('FPS {:.1f}'.format(1/(time.time() - stime)))
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break
capture.release()
cv2.destroyAllWindows()

可能是什么问题？

Answer 1

我注意到您错过了br变量中的['y']。

 for color, result in zip(colors, results):
        t1 = (result['topleft']['x'], result['topleft']['y'])
        br = (result['bottomright']['x'], result['bottomright']['y'])
        label = result['label']
        confidence = result['confidence']
        text = '{}: {:.0f}%'.format(label,confidence * 100)
        frame = cv2.rectangle(frame, t1, br, color, 5)
        frame = cv2.putText(frame, text, t1, cv2.FONT_ITALIC, 1, (0,0,0),2)

看看是否可行！

opencv对象检测需要一个整数（got类型元组）
