How does rtabmap fuse wheel odometry with visual odometry?

I set up my robot with turtlebot and kinect and excute rtabmap.

-- http://wiki.ros.org/rtabmap_ros/Tutor...

I hid the image of the Kinect sensor and moved the turtlebot.

And I moved the turtlebot to calculate the travel distance only with the kinect image.

I think the rtabmap algorithm is internally fusing image information and wheel odometry.

How are you fusing?

And do you have your own paper about fusing wheel odometry and viusal odometry?

Thank you ^ ^

Hi,

rtabmap doesn't fuse wheel odometry and visual odometry. There is only one odometry input to rtabmap node (so one or the other can be used). If you want to fuse odometries, look at the robot_localization package for example, then use its odometrry output as the odometry input of rtabmap.

cheers

I have question.

Where does RTABMAP use the incoming odometry?

hmm i want to know how rtabmap algorithm use internally odometry.

The map's graph has two kinds of links: odometry and loop closure. Odometry is used to set the transform between two consecutive nodes added to map's graph.
