摘　　要：近年来,无人机针对不同类型自然灾害应急救灾取得显著成效,但是快速获取灾情现场信息,满足第一张图应急测绘需求的机载航测系统尚未成型,无法保障应急救灾的时效性。因此,本文依据轻小型一体化多载荷集成设计,构建了基于中大型无人机飞行平台的航测相机、轻小型SAR、集成座架及定位定姿系统(POS)信号共享的一体化集成新型机载航测系统。新型机载航测系统通过控制器完成定点曝光实时成像,结合实时解算的高精度POS数据自动完成影像压缩拼接正射影像图,突破无人机机载系统成图自动化、实时化技术,打破传统航空摄影测量地面成图模式,为国家及地方救援救灾提供决策支撑。In recent years,UAVs have been effective in responding to different types of natural disasters to a certain extent,but there is no airborne aerial survey system that can quickly obtain disaster site information and meet the emergency surveying and mapping needs of the first picture,and it is difficult to guarantee the timeliness of emergency respond.Therefore,in this paper,based on the design requirements of light and small integration,an aerial camera,light and small SAR,sharing integrated mount and position and orientation system(POS)signal based on CH-4 UAV flight platform,a new type of aerial survey system integrated with multiple devices,in which the aerial camera completes fixed-point exposure real-time imaging through the low-power small controller integrated with the embedded system according to the planned to the route of the mission area,and automatically completes the image format combined with the high-precision POS data calculated in real time,and compression and splicing into orthoimage,which breaks through the automation and real-time technology of aerial mapping of drones onboard equipment,and break the traditional aerial photogrammetry ground mapping model,and guide the country and localities rescue relief of disaster providing decision support.
