Stereovslam error :: Assertion `left_.tfFrame() == right_.tfFrame()'

edit

After i publish my two left and right videos from stereo camera and run stereo_synchronizer node and stereo_image_proc node everything seems to go file but i get this error from stereo_vslam_node and see no output:

stereo_vslam_node: /opt/ros/diamondback/stacks/vision_opencv/image_geometry/src/stereo_camera_model.cpp:28: bool image_geometry::StereoCameraModel::fromCameraInfo(const sensor_msgs::CameraInfo&, const sensor_msgs::CameraInfo&): Assertion `left_.tfFrame() == right_.tfFrame()' failed.

You can zoom in the file by opening it in another window. Here is how my system looks , does anybody has anyidea what might be going wrong ??
