【摘要】 以我国自行研制的机载三线阵CCD相机为例,对基于POS的三线阵影像定位的成像模型、内方位的几何标定、外方位元素的解算以及直接定位和区域网平差方法进行了理论与实验研究。实验结果表明,利用GPS/IMU数据与摄影测量观测值进行联合平差,可以有效地克服相机内、外方位元素的系统误差,提高定位精度。更多还原

【Abstract】 A research on the image geopositioning based on POS by utilizing the domestic airborne three-line CCD camera was made.Theories and methods were studied on imaging model,geometric calibration of interior orientation elements,the solution of exterior orientation elements,direct geopositioning and bundle block adjustment.The result showed that an improvement on the positioning precision can be got from block adjustment by using GPS/IMU data and photogrammetric observation due to its efficiency to work out systematic errors in interior orientation elements and exterior ones.更多还原
