Hi Mike, hi Patrick

That works fine for me but now I have a new problem. I want to save the depth image as an video with the VideoWriter. I initialize it as follows:

cv::VideoWriter depth_writer_;

depth_writer_.open("/home/stefan/Desktop/depth_video.avi", CV_FOURCC('D','I','V','3'), 20, cv::Size(640,480),false);
                if( !depth_writer_.isOpened())
                  ROS_ERROR("[KinectTracking::KinectTracking] DEPTH failed to open!\n");

that works as well fine with me but the output is a video where three images are shown side by side. If I use the color images and set the last parameter to true that works find.

Does anybody have an idea to solve that?

Thanks a lot

Stefan
