摘要
为提高无人机倾斜摄影测量的数据采集效率,基于高分辨率单反数码相并综合顾及了相机布局、成像质量及快门同步等影响因素,研发了一种适合较大区域的六目倾斜摄影相机系统。测试及应用结果表明,该六目倾斜摄影相机比五目全画幅倾斜摄影相机外业数据采集效率提升约40%,能够在保证精度的同时显著减少总照片数量、提高据处理效率。可满足实景三维建模、地形图及地籍图测量等不同领域的应用需求。
In order to improve the data acquisition efficiency of unmanned aerial vehicle(UAV)oblique photogrammetry,a six-lens oblique camera system suitable for large areas was developed based on high-resolution single lens reflex(SLR)digital camera and taking into account factors such as camera layout,image quality and shutter synchronization.The test and application results showed that the field data acquisition efficiency of the six-lens oblique camera was about 40%higher than that of the five-lens full-frame oblique camera,which could significantly reduce the number of total photos and improve the data processing efficiency while ensuring the accuracy.It can meet the application requirements of real three-dimensional(3D)modeling,topographic map,cadastral map survey and other fields.
