visp_auto_tracker wraps model-based trackers provided by ViSP visual servoing library into a ROS package. The tracked object should have a QRcode of Flash code pattern. Based on the pattern, the object is automaticaly detected. The detection allows then to initialise the model-based trackers. When lost of tracking achieves a new detection is performed that will be used to re-initialize the tracker.
This computer vision algorithm computes the pose (i.e. position and orientation) of an object in an image. It is fast enough to allow object online tracking using a camera.
This package is composed of one node called 'visp_auto_tracker'. The node tries first to detect the QRcode or the Flash code associated to the object. Once the detection is performed, the node tracks the object. When a lost of tracking occurs the node tries to detect once again the object and then restart a tracking.
The viewer comming with visp_tracker package can be used to monitor the tracking result.

and rosmake.
