摘　　要：线阵CCD传感器在航天摄影测量时由于多种因素干扰,CCD传感器及镜头的各项参数均发生了变化,这将对定位精度产生很大的影响。本文针对ALSO/PRISM下视相机内方位检校展开分析,设置了合理的内方位参数,构建了合适的内方位模型,并以ALOS影像为例对模型精度进行了验证。Linear array CCD sensor measurements in space photography jamming a variety of factors, the parameters of CCD sensor and lens arc changed, which will have a huge impact on positioning accuracy. In this paper, the nadir camera calibration of ALSO/ PRISM was analyzed, within a reasonable set of orientation parameters, and a suitable location model was constructed. Finally an ALOS image was taken as an example to verify the model accuracy.
