| 摘 要： | 面向飞行器对地面目标的匹配系统应用,提出一种惯导信息辅助的模板校正方法.根据目标位置以及摄像机位姿信息,建立目标透视成像模型以及不同摄像机位姿下的模板校正方程;通过分析目标任意点与形心的景深关系,对校正方程进行转化并给出完整的模板校正算法.最后通过基于视景仿真技术搭建的目标模拟平台,截取不同摄像机位姿下的目标成像,并与...

| Abstract: | For the application to the ground target matching system of the aircraft,an INS-aided(Inertial Navigation System) template correction method is proposed.Firstly,the perspective projection model of the ground target was established according to the position of target and the pose(position and attitude) of camera.Then,the correction equations between the templates were deduced according to their pose parameters.By analyzing the relationship of the depth of field between each point and the centric of the targe... |
