Title:
VIDEO AND LIDAR TARGET DETECTION AND TRACKING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2014/077928
Kind Code:
A3
Abstract:
Embodiments of video and LIDAR target detection and tracking system and method for segmenting targets are generally described herein. In some embodiments, the system may perform moving target detection using three-frame difference processing on frames of LIDAR range images of a scene to identify a moving target and determine an initial position estimate for the moving target. The system may also perform segmentation of the moving target using a single frame of the LIDAR range images to generate a segmented target that may include a target mask and target centroid position. After segmentation, moving target registration including motion compensation may be performed by registering the segmented target in multiple LIDAR frames to determine a target position, a target orientation and a target heading. In some embodiments, a three-dimensional model of the moving target may be generated and added to a sequence of video frames.
