一种目标空间运动分析系统

针对运动目标空间定位问题，将立体视觉技术与单视频序列下的运动目标检测相结合，设计了一种目标空间运动分析系统，实现目标的空间定位，扩展了单视频序列运动目标检测课题的应用范围。针对从单目向多目过渡过程中面临的问题，从硬件上提出了相应的解决方案，将立体镜头与高速相机相结合，克服了芯片一致性、相机同步、运动拖影等影响。由于立体像对源于同一帧图像，所以可以直接使用传统单序列运动目标检测方法获取运动掩模。使用该空间运动分析系统在光照充足的室外条件下进行单一目标的自由落体和斜坡运动2组实验，实验结果表明:该系统运行稳定，实现了运动目标的空间位置分析功能,1 m范围内，定位绝对误差小于0.01 m。

Stereo motion analyzing system for object in space

According to the problem of spatial location for the moving object, the stereo vision technique and moving object detection in a single video sequence were combined. A stereo motion analyzing system was designed to achieve the goal of spatial location. It can expend the application range for the moving object detection issue in a single video sequence. According to the problems in the course of transition from monocular to multi-view, a solution was proposed based on the hardware. Combined the stereo lens with the high-speed camera, the problems of chip consistency, camera synchronization and the motion ghost can be overcome. Because the stereo images come from the one image, the traditional moving object detection method in a single video sequence can be used directly to obtain motion mask. Two groups of real experiments were taken by the system in full bright daylight conditions, containing free fall and slope movement. The results show that the system works stably and realizes the stereo motion analyzing capabilities for object. The absolute location error is less than 0.01 m at a range of 1 m.
