介绍了海监取证系统的应用背景，结合国内外的发展现状，借鉴POS辅助图像定位技术在航测领域上的应用，绘制大比例尺的地形图进行了目标定位。海监机载取证系统，通过集成双轴伺服稳定平台、高精度POS系统、高清摄像机等设备，配备相应处理软件，同时具备侦察目标及高精度定位能力。初步试验结果显示，当试验高度为40 m时，目标实时定位精度小于0．26 m。%Application background of the evidence collection system for maritime surveillance is introduced.In combination with its development status both at home and abroad and by reference to the application of POS-aided image location in aerial survey.Large scale topographic map was drawn for target locating.By integration of such equipment as the biaxial servo stabilized platform,high-accuracy Position &Orientation System ( POS) and HD video camera,and equipped with corresponding processing software,the airborne evidence collection system for maritime surveillance has the ability of both target reconnaissance and localization with high precision.Preliminary experimental results show that the accuracy of real-time target locating is better than 0.26 m when the flying height is 40 m.
