靶场光测多站图像多目标判读技术

Multi-tar-get interpretation technique for multi-station images of optical measurement in range

靶场光测图像处理的一个突出难题是如何分辨图像上出现的大量小目标。利用单站序列图像上目标的运动关联、目标在多站图像上像点之间的对极几何约束关系,提出了靶场多站图像多目标判读的新技术,采用单站序列图像目标卡尔曼运动轨迹预测及跟踪识别技术,以及多站图像对极几何约束同名目标匹配技术,突破了传统方法仅进行单站图像判读的局限。仿真结果证明其能有效解决多站、多目标的判读问题,已成功应用于我们研制的多套靶场图像判读系统中。

It is a difficult problem to distinguish a large amount of small targets in the processing of optical images of missile range.According to the motion relevancy of image sequence of single station and the epipolar geometry restriction of targets of multi-stations,a new technique for interpretation of multi-targets of multi-stations was proposed,which makes use of Kalman filter and epipolar geometry.The correctness and feasibility of the method have been proven by simulation data.Also the technique has been applied in sevral interpretation systems.
