摘要
本文根据现代航测中使用的大幅面数码相机原理,研制了一种五拼组合宽角近景摄影测量相机,在顾及镜头畸变和摄影景深的影响下,给出了系统设计框架、检校方法和影像后处理方法,并利用室内定轨移动摄影测量系统对相机系统进行了相关实验,实验结果表明该相机系统可用于地面大型物体近距离高精度摄影测量。
According to the principle of large format digital camera used in modern aerial photogrammetry, the paper developed a multi-camera system used in close-range photogrammetry. The system is composed of five ordinary digital cameras. Considering the effect of lens distortion and photographic depth, the paper gave the design framework of the system, the calibration method, and the images processing methods. Experiment was carried out on the multi-camera system using indoor orbit determined mobile photogrammetry system, and the results showed that the multi-camera system could be used for the high precision photogrammetry of the ground large objects.
