【摘要】 随着PC/104嵌入式计算机技术的快速发展,数字航空摄影在航空遥感领域已经发展成为热点。轻小型飞机是低成本的新型遥感平台,它要求装载的遥感仪器体积小、重量轻、抗震性好。PC/104嵌入式计算机较好的满足了此要求,并具备开发周期短的优势。在航摄仪器中应用的数码相机单相机的成像面是有限的,为了提高航空作业时的工作效率根据航空摄影测量的要求需将四个同型号的相机组合在一起工作,因此相机的同步曝光、曝光信号的同步发送、GPS坐标的实时获取以及飞行记录文件的实时存储成为关键,相机的单机加固、单机检校、平台检校的方法研究是整个研制的基础,各子系统之间的柔性连接、电磁兼容、抗干扰设计成为保障。在获取正确的数字影像后,对影像格式的正确转换、畸变校正以及缩略影像拼接是对以后做正射影像、空中三角测量做好坚实的基础。本文就是结合现代电子技术与航空摄影测量的要求,以PC/104嵌入式计算机为控制系统的数码航空摄影测量仪逐步解决了这些问题并应用到实际生产实例当中。论文不仅给出了课题设计的设计思想、技术路线、整体框架、部分实物图和原理图及测试结果,并且还奔赴许多省份做了大量的试验数据进行严密分析,设计的成果具有较高的性价比,应用前景比较好。更多还原

【Abstract】 Along with the PC/104 rapid development of embedded computer technology, digital aviation photography in the airline has become a hotspot in remote sensing. Light small airplanes are low cost of new remote sensing platform, it requires the load of remote sensing equipment is small in size, light weight, good vibration resistance. PC/104 embedded computer better satisfy this requirement, and has the advantage of short development cycle.Digital camera single camera imaging surface is limited in the application of aerial photography instrument. In order to improve the working efficiency of the air operation, we will Put four cameras together work according to the requirement of aerial photogrammetry.So the camera’s synchronous exposure and sent, GPS coordinates of real-time access and flight record files stored in time become key. The camera’s standalone reinforcement, Single camera calibration and platform of methods study calibration are based. Flexible connection, electromagnetic compatibility and Anti-interference design between subsystems become guarantee. The correct image format conversion calibration and Thumbnail images mosaics after acquiring the correct digital image which are very important for doing Point-blank images and Air triangle measuring. This paper is combined with the modern electronic technology and aerial photogrammetry, at the request of the PC/104 embedded computer for control system of digital aviation photography measuring instrument gradually solve these problems and apply to the actual production examples of.The paper product design not only gives the design thought, technical route and the overall framework, part of the real figure and principle diagram and test results but also to many provinces did a lot of test data are rigorous analysis, design products with high performance-to-price ratio, market prospect is better.更多还原
