在对特定人员位置识别并实时跟踪进行视频采集的应用中, 基于ARM9 S3C2410处理器并搭载CCD成像单元、红外波段滤光片和两自由度云台实现了一个全自动红外目标识别系统, 在采集并分析红外图像样本基础上, 设计了一种快速的图像二值化算法, 通过自动分割、快速搜索比对等步骤, 实现了对既定红外目标的实时检测和运动跟踪, 该系统简单可靠, 便于嵌入各类自动化应用设备。

In the application of recognizing the position, tracing and video collecting in real time for a special person, a full-automatic Infrared target recognizing system is designed, which consists of a ARM9 S3C2410 processor, charge coupled device (CCD) imaging units, Infrared filter and 2 degrees of freedom pan tilt. A fast image binaryzation algorithm is designed based on collecting and analyzing Infrared image samples. Through automatic segmentation, fast searching and contrasting, the detection and motion tracing on known Infrared targets in real time are realized. The system is simple, reliable and easy to be embedded in automatic equipments.
