超轻型飞机GPS导航与摄影控制

低空超轻型飞机可以实现云下飞行,为大比例尺低空数码航空摄影测量提供了航空平台。本文将基于我国的超轻型飞机平台,设计机载低空数码航摄GPS导航和定点曝光控制系统,详细阐述了导航算法,并对"一机两屏"的方案进行了分析。通过自动定点曝光控制,保证航摄影像的前后、左右重叠度,试验结果显示该系统稳定可靠。

GPS navigation and digital photogrammetric camera control using super-light aircraft

Super-light aircraft has a very good performance of flying under cloud,which makes it possible for large-scale low altitude digital aerial photogrammetry,especially in south-west China region.Based on China-made "Mifeng" super-light aircraft platform,this paper presented an innovative design of airborne GPS navigation and digital photogrammetric camera control system.An advanced algorithm of GPS navigation was given in details along with a creative navigation solution,named "one computer double screen"With automatic photo shooting on pre-designed point,the suggested system would realize and ensure the overlap rate of two adjacent images in front-end direction and left-fight direction.Test results showed that the suggested system had a very good reliability and stability performance.
