Hi，I'm using roslaunch find_object_2d find_object_3d_kinect2.launch to find object.But error occurs at the end of the adding object from taking a picture .Here are some error information ：

Could you give me some advice ? Thank you!

I cannot reproduce the error:

$ roslaunch kinect2_bridge kinect2_bridge.launch publish_tf:=true
$ roslaunch find_object_2d find_object_3d_kinect2.launch

then "Edit->Add object from scene...", take picture, select object and add it.

Is it crashing every time you add a new object?

I have solved this problem by installing opencv nonfree.
