Anaglyphs with OpenCV

Here is a quick function that returns an anaglyph image from two sources. For the 3D goggles, I use Filter #25 for red and #58 for green. Depending on which side you load the source images, you need to check for which side is red or green. // Return an anaglyph image of a right and left channel // Author : Nicolas Bourré 20100927 IplImage * toAnaglyph(IplImage * imgLeft, IplImage *imgRight) { IplImage *iplReturn; IplImage *l_R, * l_G, *l_B; IplImage *r_R, * r_G, *r_B; iplReturn = cvCreateImage( cvGetSize (imgLeft), 8, 3); l_R = cvCreateImage( cvGetSize (imgLeft), 8, 1); l_G = cvCreateImage( cvGetSize (imgLeft), 8, 1); l_B = cvCreateImage( cvGetSize (imgLeft), 8, 1); r_R = cvCreateImage( cvGetSize (imgLeft), 8, 1); r_G = cvCreateImage( cvGetSize (imgLeft), 8, 1); r_B = cvCreateImage( cvGetSize (imgLeft), 8, 1); cvSplit(imgLeft, l_R, l_G, l_B, NULL); cvSplit(imgRight, r_R, r_G, r_B, NULL); cvMerge(r_R, r_G, l_B, NULL, iplReturn); cvReleaseImage(&l_R); cvReleaseImage(&l_G); cvReleaseImage(&l_B); cvReleaseImage(&r_R); cvReleaseImage(&r_G); cvReleaseImage(&r_B); return iplReturn; } In my case, I needed a quick solution so I didn’t calibrate the cameras for spatial correction. Enjoy this little snippet!
