栅格化极坐标目标定位方法

Rasterized Polar Coordinate Target Positioning Method

针对战场侦察等环境下,目标侦测定位需要快速、多目标、全方位等特点,本文设计提出栅格化目标定位方法。介绍了该定位方法实现的集成激光测距、热像仪等仪器的一体化平台,利用具有夜视作用的热像仪做图像采集,激光测距仪标定距离,电子罗盘定向;信息处理单元运用图像处理技术,在采集数据的基础上建立栅格化极坐标模型,目标进入能够快速匹配对目标定位,实现全方位快速目标检测定位,尤其对群多目标定位具有较大优势。

For battlefield reconnaissance and other environmental objectives detection positioning have the features of quickness, multi-target, and omnibearing, this paper proposes and designs rasterized polar coordinate target positioning method and describes the integrated platform to achieve the method, which integrated laser rangefinder, thermal imager and other equipment. The platform uses a thermal imager with night vision effect for image acquisition, a laser rangefinder for calibrating distance and an electronic compass for calibrating orientation. The information processing unit uses image processing technology to set up rasterized polar coordinate model based on collected data. The method can quickly complete the matching positioning when the target passes into, achieve all-round rapid target detection and location, and especially has a large advantage for multi-targeting group.
