Overview

This package contains one single node: viodom_node, which estimates robot motion based on incoming raw images and IMU mesaurements from the Visual-Inertial (VI-) Sensor. To correctly estimate the motion, the node first needs to wait for a few seconds to initialize an IMU filter.

Tf tree

The transforms tree (following REP 105) is as follows:

• odom → base_link → camera

Visual odometry algorithms generally calculate camera motion. To be able to calculate robot motion based on camera motion, the transformation from the camera frame to the robot frame has to be known. Therefore this implementation needs to know the tf base_link → camera to be able to publish odom → base_link. The node currently uses default values from the sensor setup on the AscTec Neo Research platform.
