Bug about Linemod detection

[yuhan1010]

Hi everyone,

when I try to run the detect code following official guide, there are some problems I meet:

yuhan@ubuntu:~/ork_ws$ rosrun object_recognition_core detection -c  `rospack find object_recognition_linemod`/conf/detection.ros.ork

I have no idea why it happened, it is a problem about resolution of figures or sth else?

thx.
