My team and I have built the following setup (view from above). It's a 3x3x3m aluminum grid with 4 Kinects placed at height 2.1~2.2m and are facing downwards (at 20~30 degrees). The angle between the neighbors is 90 degrees. At this point I need to merge point clouds from all these cameras (camera calibration, manual transformations have been applied). The question is: do I merge them to one single camera one by one, or follow clockwise/counterclockwise direction, or there is a better way to merge them?
