人工光源对波门形心跟踪影响的分析

Artificial Illuminator Effect on Gate Centroid Tracking

研究人工光源对红外成像跟踪的影响对保证跟踪稳定性具有重要的意义。文章以波门形心跟踪为例,详细介绍了波门形心跟踪算法的原理,在分析人工光源对形心跟踪的影响基础上,通过对不同光源照射参数时目标的形心跟踪效果进行了实验。结果表明:当光源照射参数不同时,目标的形心跟踪误差将不同,相同条件下,光照功率越大,光照时间越长,照射距离越近时,目标的形心误差越大,垂直照射比平行照射时的误差大。

Study on artificial illuminator effect on infrared imaging tracker is a great signification to keep the tracker＇s stability.In this paper,taking the gate centroid tracking for example,the principle of a gate centroid tracking is introduced detailly,based on the effection of gate centroid tracking from ten illuminators,the targets＇s centroid tracking effection through different parameters is tested.The results show that centroid tracking error is differential under differential illuminators＇s parameters,in the same condition,the greater centroid tracking error with bigger power,longer time,nearer distance and the vertical direction.
