5 years ago Hello zhongxin,
I know this is a quite late response but maybe this response can help others. I used to have that same problem, in my case it was because I loaded my own models that were in mm instead of meters.
What you reported happens when no objects are found. Try lowering the threshold in the .conf file to a low number like 30. In that case prettymuch anything looks like a model and it should give a response. In my case this showed a gigantic model in rviz (1000x too large).
I hope this helps you or others solve probles like these.
hello everyone I
m now using linemod to detect the coke can with the ORK tutorials after the linemod training when I run the detection it cant detect anything in rviz.grxuser@grxuser-XPS-8900:~/catkin_ws/src/ork_tutorials/data$ rosrun object_recognition_core detection -c
