【Abstract】 A new method for change detection and 3D locating in real-time image sequences is introduced, namely bit-planes differential motion detection and projected matrix spatial locating algorithm. The method marks images by flat-fields with different information of different bit-planes, then makes motion detection, and uses the images got by a single camera for 3D locating. Compared with other classic change detection and spatial locating methods, this method provides an advantageous performance in speed, accuracy, complexity and robustness. The proposed algorithm has shown a perfect performance in the real-time video monitoring at railway crossing.更多还原
