相机几何参数是影响卫星影像几何精度的重要因素。基于地面试验场的相机参数在轨标定是解决参数变化的有效手段,但其标定结果受制于试验场影像的获取,且两次标定间相机参数变化难以确定。因此,本文提出在相机参数定期在轨标定的基础上,... 相机几何参数是影响卫星影像几何精度的重要因素。基于地面试验场的相机参数在轨标定是解决参数变化的有效手段,但其标定结果受制于试验场影像的获取,且两次标定间相机参数变化难以确定。因此,本文提出在相机参数定期在轨标定的基础上,辅助监测相机光轴,在轨实时监测的相机夹角,并进行模拟仿真试验。试验结果表明,该方法能有效对相机夹角进行在轨辅助监测。 展开更多

This paper describes the structure, geometric model and geometric calibrationof Photogrammetron Ⅰ - the first type of photogrammetron which is designed to be a coherent stereophotogrammetric system in which two cameras are mounted on a physical base but driven by anintelligent agent architecture. The system calibration is divided into two parts: the in-labcalibration determines the fixed parameters in advance of system operation, and the in-situcalibration keeps tracking the free parameters in real-time during the system operation. In a videosurveillance set-up, prepared control points are tracked in stereo image sequences, so that the freeparameters of the system can be continuously updated through iterative bundle adjustment and Kalmanfiltering. 展开更多
