复杂场景下的单目标跟踪和多目标跟踪是视觉目标跟踪中最困难的不足一直没有得到很好的解决。

Complex scenarios single target tracking and multi-target tracking is the most difficult visual target tracking problem has not been solved.

针对匀速航路、匀加速航路和拐弯航路的数字仿真得出：序贯滤波、并行滤波和最优数据压缩滤波可以很好的跟踪目标且精度较单雷达跟踪有明显的改善。

The conclusion is that sequential filtering, parallel filtering and optimal data compress filtering can run after all kinds of track and the precision of tracking is better than radar.
