IMU/DGPS辅助航空摄影新技术的应用
IMU DGPS 航空摄影测量
2009/11/24
利用IMU/DGPS组合导航技术，可以在航空摄影的同时直接获取像片的外方位元素。试验表明，只要对IMU/DGPS与航摄仪的集成系统误差和漂移误差进行检校和改正，直接获取的像片外方位元素可以用于正射影像的制作和中小比例尺测图。本文首先讨论了IMU/DGPS组合导航技术和IMU/DGPS辅助航空摄影系统的工作原理； 然后，结合甘肃酒泉试验数据，重点分析讨论了IMU/DGPS和航摄仪集成系统的误差及其检...
推导了ADS40航带间外方位元素归一化处理的数学公式，设计了一种描述IMU/DGPS系统误差的数学模型，采用改进的定向片内插模型实现了ADS40影像的区域网平差。试验结果表明，仅需一个地面控制点，IMU/DGPS数据的定位精度就可显著提高，在四角布设地面控制点的情况下，IMU/DGPS数据与ADS40影像的联合平差可得到优于1.5个像素的3维定位精度；构架航线对平差结果的改善作用有限，在作业中采用...
