Undisort(DShow9 OpenCV) is not calibrating

Hello. I’m trying to calibrate my kinect camera by Undisort(DShow9 OpenCV) but it’s never found all of calibrating corners o test pattern, so it’s can’t start calibrating process. Is anyone tested this node with another cameras? Or maybe i’m doing something wrong? My grid is 10x7, each quad is 30mm/30mm.
