摘　　要：在运动目标跟踪方面,运动目标跟踪算法直接影响着运动目标跟踪的准确性和稳定性,现有的目标跟踪算法大多是基于特征或运动信息的,虽然能够完成对运动目标的可靠跟踪,但是需要处理的数据量大,运算复杂,很难达到实时跟踪的要求。本文首先阐述了跟踪算法中模板相关匹配算法的基本原理,然后跟踪系统的实际需求,详述了投影法快速定位目标跟踪的方法,并给出了投影算法跟踪的实验结果,该算法基本能满足跟踪系统中运算量小和实时性的要求。For moving object tracking, the accuracy and stability of objects tracking depend on moving objects tracking algorithms to a great extent. Most of the current approaches proposed are mainly feature-based or motion-based. These approaches are reliable to track objects, but they have a lot of data to be processed and they are too complicated to apply in real time. First this paper analyzes the basic principle of template-matching method, a typical model of target tracking. Then we explicate how to achieve fast positioning and tracking of the target according to the actual demand of the system, and list out the result of such experiment based on projection. This real-time tracking method boasts little computation and turns out to be a good choice.
