摘要
为解决电视经纬仪跟踪测量系统中对运动目标快速识别定位的要求 ,在深入分析运动目标特性和电视经纬仪跟踪测量系统特点的基础上 ,利用经纬仪角度变化信息 ,对运动目标图像序列进行帧间差值计算以获得目标残差图 ,并基于残差图提出了一种新型的运动目标快速识别方法 ,大大减少了运算量 结合中值滤波和图像二值化 ,实现了运动目标的快速定位 通过对目标实测图像序列的实验 ,结果证明 :该算法具有快速、稳定、有效等优点 。
To meet the demand of TV theodolite tracking system, a new algorithm is proposed in this paper. According to the characteristics of moving targets and tracking system, fast image difference computing method based on angle changes of TV theodolite is found, with calculation much reduced. Then after median filtering and image segmentation of difference image,precision location for targets accomplished. Experiment results prove it a fast, stable, effective algorithm and a real-time processing mode in tracking system.
