【摘要】：为了得到径向畸变、切向畸变和非方形像元改正3种镜头畸变参数最优化的组合,提高航测时的像点量测精度,研究了不同畸变参数组合条件下对像点量测精度的影响。采用3种型号的镜头对辽宁工程技术大学北校区进行了航测,并利用Virtuozo AATPATB空三软件测试了几种典型组合下的航测结果精度。试验结果表明:在条件允许的情况下,尽可能采用较为全面的畸变参数能够最大限度地提升航测结果的精度;当条件有限时,采用K1和K2组合的模型可以消除大部分镜头畸变带来的影响,对结果精度的提升最为显著。研究成果可以为其他无人机航测任务提供参考。
[Abstract]:In order to obtain the optimal combination of three lens distortion parameters, radial distortion, tangential distortion and correction of non-square pixel, the effect of different distortion parameters on the accuracy of image point measurement is studied. The aerial survey of North Campus of Liaoning University of Engineering and Technology was carried out by using three kinds of lenses, and the accuracy of aerial survey results under several typical combinations was tested by using Virtuozo AATPATB software. The experimental results show that the accuracy of aerial survey results can be maximized by using more comprehensive distortion parameters when conditions permit, and when conditions are limited, The model combined with K1 and K2 can eliminate the influence of most lens distortion and improve the accuracy of the result. The research results can provide reference for other UAV aerial survey missions.
