我正在尝试在 python 中使用 opencv 跟踪红色对象。这是我到目前为止的代码：

    #convert the image to HSV
    hsv=cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

    #lower threshold for red
    lower_red=np.array([0, 100, 75])
    #upper threshold for red
    upper_red=np.array([5, 76, 100])

    mask=cv2.inRange(hsv, lower_red, upper_red)

当我运行它时，出现的错误如下：

OpenCV Error: Sizes of input arguments do not match (The lower bounary is             neither an array of the same size and same …
