Against the existing practical problems of photogrammetry by most current UAVs with a single digital camera, a design of the multi-format combined camera is analyzed detailedly. Taking PHASE ONE IQ180 as an ex-ample, its combination parameters and corresponding relations are discussed by comparing the combination modes and imaging characteristics of doubly combined camera with triply combined camera to analyze the effects of mosaic error and elevation accuracy. It is concluded that combined camera has obvious advantages in improving elevation accuracy, increasing picture format, enhancing operation efficiency and so on, which has some guiding signifi-cance to the design of multi-format combined camera.%针对当前大多UAV搭载单个数码相机进行摄影测量时存在的实际问题,详细分析了多面阵组合相机的结构设计.以飞思IQ180相机为例,通过比较双拼组合相机与三拼组合相机的组合方式及各自成像特点,对其相机的组合参数以及相应关系进行探讨;并通过对拼接误差与高程精度的影响分析,得出组合相机对高程精度的提高、增大像幅、提高作业效率等方面有明显的优越性,对多面阵数码相机的设计具有一定的指导意义.
