如何使用 OpenCV 将 Bayer 转换为 RGB，反之亦然 [英] How do I convert Bayer to RGB using OpenCV and vice versa

问题描述

OpenCV 提供了将 Bayer 转换为 RGB 的函数，但是如何使用这个 CV_BayerBG2BGR 和其他类似的函数?我使用了下面的代码，但错误显示为无效频道号.由于我使用 RGB 图像作为 originalImage，那么这个函数实际上是如何工作的?

OpenCV provided function to convert Bayer to RGB, but how to use this CV_BayerBG2BGR , and other similar function? I used code below, but the error appears stated invalid channel number. Since I use RGB image as originalImage, anyway how this function actually works?

void main(){
// Declare and load the image
// Assume we have sample image *.png
IplImage *originalImage = cvLoadImage("bayer-image.jpg",-1);

// The image size is said to be 320X240
IplImage *bayer2RGBImage;
bayer2RGBImage = cvCreateImage(cvSize(100,100),8,3);
cvCvtColor(originalImage,bayer2RGBImage,CV_BayerBG2BGR);

//Save Convertion Image to file.
cvSaveImage("test-result.jpg",bayer2RGBImage);

//Release the memory for the images that were created.
cvReleaseImage(&originalImage);
cvReleaseImage(&bayer2RGBImage);}

另外，我也想把普通的RGB图像转换成bayer格式(比如双线性)，openCV是否也提供这个功能?

Furthermore, I'd like to convert common RGB image to bayer format (let say bilinear) too, whether openCV provide this function as well?

任何帮助将不胜感激.

提前致谢.

推荐答案

遗憾的是 OpenCV 不提供 BGR 到 Bayer 的转换.只能向后转换.

Unfortunately OpenCV does not provide BGR to Bayer conversion. Only backward conversion is available.

如果您需要转换为 Bayer 格式，那么您应该自己实现此转换或使用其他库.

If you need a conversion to Bayer format then you should implement this conversion yourself or use another library.
