中画幅量测相机与高精度POS系统的集成与应用

Integration and Application of Medium Format Metric Camera and High Precision POS System

介绍了中画幅量测相机与高精度POS集成的航空摄影测量系统及其工作原理,该摄影测量系统能捕获高分辨率、高清晰原始影像,同时采集相机曝光瞬间的高精度位置姿态数据,系统结构紧凑,具备单架次130 km2以上5 cm分辨率影像数据的获取能力,兼具高空摄影的成像精度和低空摄影的灵活性,可作为现阶段航空摄影领域的重要补充。

We described the working principle of the aerial photography surveying system, which was integrated by medium format metric camera and high precision POS system in this paper. The photography surveying system is able to capture the high-definition resolution images and collect the high precision data of position and orientation synchronously with the camera exposure. The system has a compact structure, and it's able to collect the data of 5-centimetre resolution image during one single flight. This system preserves the mapping accuracy of highaltitude aerial photography and the flexibility of low-altitude aerial photography, which is an important supplement of the current aerial photography field.
