运行 cv2.getRectSubPix(img, (5,5), (0,0)) 抛出错误:

OpenCV Error: Unsupported format or combination of formats (Unsupported combination of input and output formats) in getRectSubPix.

imgdtypefloat64,由img.dtype决定。

最佳答案

查看源代码表明 getRectSubPix 的输入组合只有:

depth == CV_8U && ddepth == CV_8U

depth == CV_8U && ddepth == CV_32F

depth == CV_32F && ddepth == CV_32F

这意味着输入数组需要转换为int8或float32才能传入,这可以通过以下方式完成:

np.int8(img)

np.float32(img)
