从视频像素灰度序列中提取特定人员的状态特征，采用平面阵对特征信息进行融合处理是实现计算机视觉下特定人员定位的重要步骤。传统的人员视觉定位方法采用视频步进跟踪学习方法，在随机状态分布下的复杂环境人员进行准确定位效果不佳，提出一种基于平面圆阵定位算法的特定人员计算机视觉定位方法，提取监控视频的图像，进行视频图像的背景建模，得到高斯差分尺度空间中的背景像素灰度值，实现对特定人员的表情识别的动作判别，以此为数据基础设计平面圆阵人员定位系统，实现对暴恐等特定人员的准确锁定和跟踪识别。仿真实验表明，采用该算法准确实现1500 m远距离暴恐人员特征识别与定位，误差较小，分辨率和准确性较高。

The extraction of characteristics of specific personnel from video pixel sequence, planar array is used for feature information fusion, this is an important step for the realization of specific personnel positioning. Traditional video step track-ing method is used for positioning, but the positioning effect is bad when the environment is complicated. An improved spe-cific personnel positioning algorithm is proposed based on plane circular array processing, and the video image is extracted, the background modeling of video image is taken, and background pixel gray value in Gauss differential scale space, the fa-cial expression recognition of specific personnel action discrimination are realized. Based on this, plane circular array per-sonnel positioning system is designed, specific personnel accurate locking and tracking identification are realized. Simula-tion results show that this algorithm can achieve long distance violent terrorist personnel feature recognition and positioning as far as 1500 m. The error is lower, and it has high resolution and accuracy.
