rtabmap+bumblebee.launch+stereo_mapping.launch

edit

When I use my own camera Bumblebee2 and rtabmap_ros to do the experiment,there are something wrong.

  roslaunch rtabmap_ros bumblebee.launch
  roslaunch rtabmap_ros stereo_mapping.launch

After that there come to some error message:

  stereo_odometry: /home/exbot/catkin_ws/src/vision_opencv/image_geometry/src/stereo_camera_model.cpp:36: bool image_geometry::StereoCameraModel::fromCameraInfo(const CameraInfo&, const CameraInfo&): Assertion `left_.fx() == right_.fx()' failed.

Does anyone know why? Thank you very much for your reply!
