基于联合变换相关的目标跟踪方法

成像跟踪制导中，相关跟踪技术占有重要的地位。基于联合变换相关的目标跟踪方法，使用图像序列的相邻两帧图像依次进行相关运算，提取相关结果中互相关峰的位置和相邻两帧图像时间间隔等信息，即可得到目标位置、方向和速度的变化情况。计算机仿真实验结果表明:该算法有效地解决了传统相关跟踪算法中存在累积误差和容易使目标漂移出其参考模板的问题，可以实现稳定跟踪。

Target tracking method based on joint transform correlation

Correlation tracking technology plays an important role in image tracking. A tracking method based on joint transform correlation was studied. Adjacent frames in image series were sequentially operated, then the position of the correlation peak and the time interval of adjacent frames were obtained. These data enabled us to get the changes of target in position, direction and velocity. Simulation results show that the proposed method solves the problems in traditional algorithms which have accumulated errors and are easy to make targets drift out of the reference template , and can recognize and track the target steadily based on joint transform correlation.
