我也试图做同样的事情，因为需要将处理过的图像与两个库结合起来.我尝试做的是将 byte[] 放入 Mat 而不是 RGB 值.它奏效了！所以我所做的是:

I also was trying to do the same thing, because of need to combining image processed with two libraries. And what I’ve tried to do is to put byte[] in to Mat instead of RGB value. And it worked! So what I did was:

1.Converted BufferedImage 到字节数组:

1.Converted BufferedImage to byte array with:

byte[] pixels = ((DataBufferByte) image.getRaster().getDataBuffer()).getData();

2.然后，如果您将 type 设置为 CV_8UC3

2. Then you can simply put it to Mat if you set type to CV_8UC3

image_final.put(0, 0, pixels);
