Geometric Calibration of ADS40 System Based on Test Field

  • 摘要: 分析了ADS40影像的几何特性和相机检校模型,设计了一套针对ADS40系统的检校方案,并基于地面检校场的实际数据进行了验证。实验结果表明,通过合理的检校,可以获得ADS40高精度的检校文件,提高摄影测量的精度,并降低对控制点的依赖性。

     

    Abstract: The particular sensor geometry of the airborne Three-Line-Scanner ADS40 brings particular process.Sensor calibration is important process of photogrammetry.Recently,people tended to research on estimating the performance of the calibration file and analyzing the influence of self-calibration.In contrast,the goal of this paper was to generate a sufficient calibration file based on test field calibration.The paper describes the mathematical model of GPS/IMU supported aerial triangulation of ADS40,designs a set of calibration process,and gives results using the data of the test site.Experimental results show that the calibration of the ADS40 is effective to improve data accuracy and reliability.
