Abort when runing pose calibrator

[ns15417]

I got an error when running pose calibrator, which abort at the file ChainBundle.cc line 1011. I dont know what happed cuz i just followed the instruction on the file "Getting-Started.pdf" . In the section of pose calibrator, it says "Once running, point the first camera (image outlined in bright blue) at the checkerboard until it is found, then press [Spacebar]", i got the image and my first camera recognized the chessboard and then i hit [Spacebar], but it aborted. `[ INFO] [1559113809.600338404]: TrackerCalib: camera1 just initialized with checkerboard! [FATAL] [1559113809.817671649]: ASSERTION FAILED file = /home/shinan/catkin_ws/src/mcptam/src/ChainBundle.cc line = 1011 cond = _pAbortFlag
