利用激光测距数据处理线阵卫星摄影测量影像

以线阵CCD测量相机为有效载荷的传输型卫星是目前获取影像的有效途径。本文针对两线阵卫星影像摄影测量处理的相关问题,提出将激光测距数据用于相机焦距在轨标定和光束法平差的理论及数学模型,并进行了实验验证。实验表明利用激光测距数据参与两线阵影像处理,能够满足测制1∶10 000比例尺地形图精度要求。

Application of laser distance measurement data in linear array satellite photogrammetry

Using linear array CCD cameras as payload in transmission satellites is an effective way of image acquisition.In order to solve some problems in the photogrammetric processing of two-linear-array satellite image,it was proposed to apply the laser distance measurement data in the theory and mathematical model of in-flight calibration focus of camera and bundle adjustment in the paper.It performed verification test finally,and the results showed that the participation of laser distance measurement in the two-linear-array image processing could meet the requirement of accuracy in producing 1∶ 10 000 scale topographic map.
