摘要
针对应急测绘中无人机视频数据缺少地理信息而无法实现视频空间定位及分析等问题,该文提出了以旋翼无人机为平台搭载高清成像设备和定位测姿模块实时获取带有地理信息的视频影像的技术方案。在无人机视频信号处理和地理信息获取的基础上,利用VS2010软件编程平台开发了一套无人机地理信息视频系统,系统结合二维地理信息平台,实现了无人机航迹坐标的实时展示、关键帧与地理信息平台实时匹配、距离和面积量测等功能。飞行测试结果表明,无人机地理信息视频系统具有实际应用价值。
Aiming at the problem that unmanned aerial vehicle（UAV）video lacks geographic information so that it cannot realize the real-time location and spatial analysis in emergency surveying and mapping,a technical scheme that selected unmanned gyroplane as platform boarding high-definition cameras and position and orientation module to acquire real-time video images with geographic information was proposed in this paper.Based on video signal processing technology and geographic information acquisition method,the UAV geographic information video system was developed by using VS2010,which could show UAV track coordinate on the two dimensional geographical information platform,match video key frame with geographic information and survey distance and area.The result of fright test showed that the UAV geographic information video system has practical application value.
