Continuous Region Tracking using PTZ Thermal Infrared Imager

We propose a real-time keypoint tracking and mapping approach for continuous region tracking. The proposed approach is realized in a parallel way, which can be substantially optimized for multi-core processor. One thread tracks the keypoints employing our ultra-low-weight keypoint detector and hybrid SP-Tree, and the other thread handles the 3D mapping task. Experiments are conducted to demonstrate that the proposed approach can keep high accuracy while substantially reducing the computational load. In conjunction with background segmentation, the proposed approach can address region tracking task using PTZ Thermal Infrared Imager.
