摘要
为了解决大视场红外告警系统中目标定位精度较差的问题, 采用一种基于主动标志物的多项式拟合法, 对大视场红外告警系统中目标方位提取进行了理论研究和实验验证。利用高温陶瓷加热片模拟红外目标, 通过高精度2维转台获得相机姿态角与目标中心坐标的对应数据点集, 采用二元高阶多项式对目标方位信息进行拟合, 实现了大视场红外告警系统中目标高精度方位提取。结果表明, 该拟合方法的角度误差在±0.1°以内, 目标定位精度较高。这一结果有助于大视场红外成像中目标方位的提取。
Abstract
In order to solve the problem of poor target location accuracy in wide-field infrared alarm system, a polynomial fitting method based on active markers was used to extract target location in wide-field infrared alarm system. A high-temperature ceramic heating plate was used to simulate an infrared target, and a high-precision 2-D turntable was used to obtain the corresponding data point set of the camera’s attitude angle and the target center coordinates, and a binary high-order polynomial was used to fit the target orientation information. The high-precision azimuth extraction of the target in the large-field infrared warning system was realized. The experimental results show that the angle error of the fitting method is within ±0.1°, and the target positioning accuracy is high. This result is helpful for target azimuth extraction in large-field infrared imaging.
