摘要
遮挡问题是目标跟踪算法中的难点问题之一。用模糊算法模拟人脑的记忆过程,结合图像序列的时间相关性和空间相关性,采用模糊分析方法实现对运动目标的动态跟踪,取得了很好的效果。本文针对目标被局部遮挡或者伪目标干扰等情况,提出了基于分层模板匹配与模糊跟踪相结合的目标跟踪算法。该算法在matlab软件环境下进行了仿真实验。实验结果表明:算法实现了跟踪过程中目标存在遮挡问题、伪目标干扰时的稳定的、实时的跟踪。
Occlusion is one of the difficult problems in target tracking algorithm. Using fuzzy algorithm to simulate the human memory process, combined with the temporal correlation and spatial correlation of image sequences, fuzzy analysis is employed to traclc moving object dynamically, and good result is achieved. It case of the target being partially occluded or false target jamming etc. , a target tracking algorithm is put forward by combination of hierarchical template matching and fuzzy tracking. Simulation experiments are carded out in MATLAB software environment. The experimental results show that the algorithm realizes stable and real - time target tracking process in the presence of occlusion, pseudo target interference.
