摘要

We present an integrated system for the recognition, pose estimation and simultaneous tracking of multiple objects in 3D scenes. Our target application is a complete semantic representation of dynamic scenes which requires three essential steps; recognition of objects, tracking their movements, and identification of interactions between them. We address this challenge with a complete system which uses object recognition and pose estimation to initiate object models and trajectories, a dynamic sequential octree structure to allow for full 6DOF tracking through occlusions, and a graph-based semantic representation to distil interactions. We evaluate the proposed method on real scenarios by comparing tracked outputs to ground truth trajectories and we compare the results to Iterative Closest Point and Particle Filter based trackers.
