I'm trying to run the sensor_fusion.launch example for RTAB-Map, but I'm getting the following error:
[ WARN] [1529175256.460112956]: odometry: Could not get transform from base_link to camera_rgb_optical_frame (stamp=1529175256.355035) after 0.10000 seconds ("wait_for_transform_duration"=0.100000)!
Error="Could not find a connection between 'base_link' and 'camera_rgb_optical_frame' because they are not part of the same tree.Tf has two or more unconnected trees.. canTransform returned after 0.101323 timeout was 0.1."
I've attached a copy of my TF tree graph. How can I connect the two trees? I'm using i2c_imu with rtimulib to pull data from the IMU, and libfreenect to get data from a Kinect 360.
