Webb最佳答案. 该错误意味着图像已经是“颜色” (意味着它已经有 3 个 channel )。. OpenCV 无法从 GRAY 转换它至 RGB 因为灰度图像只有一个颜色 channel 。. CV_8UC3 意味着您有 3 个 8 位深度的颜色 channel 。. 如果你真的想确保你有一个 CV_8UC3 ，您可以在制作图像时尝试这样的 ... 1 Answer Sorted by: 2 You specified the color space conversion code as COLOR_RGB2GRAY. This means your input ( frame) should be in RGB format and output ( grey2) will be in gray format. The problem is you created frame input as CV_8UC1 (8-bit single-channel array). You can create it as CV_8UC3 (3-channel) to fix the problem. Share
