python - 类型错误 : Scalar value for argument 'color' is not numeric in openCV

Question

这是我的代码

im = cv2.imread('luffy.jpg')
gray = cv2.cvtColor(im,cv2.COLOR_BGR2GRAY)
ret,thresh = cv2.threshold(gray,127,255,0)

contours,h = cv2.findContours(thresh,cv2.RETR_TREE,cv2.CHAIN_APPROX_SIMPLE)

for cnt in contours:
    moment = cv2.moments(cnt)
    c_y = moment['m10']/(moment['m00']+0.01)
    c_x = moment['m01']/(moment['m00']+0.01)
    centroid_color = im[c_x,c_y]
    centroid_color = np.array((centroid_color[0],centroid_color[1],centroid_color[2]))
    print type(centroid_color)
    cv2.fillPoly(im,cnt,centroid_color)

我在最后一行尝试将 centroid_color 传递给颜色参数时遇到该错误。是<type 'numpy.ndarray'>并且我已经能够将此数据类型作为其他实例中的颜色成功传递到 cv2.fillPoly 中，所以我不确定为什么它会在这里出现问题。

Answer 1

centroid_color = tuple ([int(x) for x in centroid_color])
