【摘要】：為了得到徑向畸變、切向畸變和非方形像元改正3種鏡頭畸變參數(shù)最優(yōu)化的組合,提高航測(cè)時(shí)的像點(diǎn)量測(cè)精度,研究了不同畸變參數(shù)組合條件下對(duì)像點(diǎn)量測(cè)精度的影響。采用3種型號(hào)的鏡頭對(duì)遼寧工程技術(shù)大學(xué)北校區(qū)進(jìn)行了航測(cè),并利用Virtuozo AATPATB空三軟件測(cè)試了幾種典型組合下的航測(cè)結(jié)果精度。試驗(yàn)結(jié)果表明:在條件允許的情況下,盡可能采用較為全面的畸變參數(shù)能夠最大限度地提升航測(cè)結(jié)果的精度;當(dāng)條件有限時(shí),采用K1和K2組合的模型可以消除大部分鏡頭畸變帶來的影響,對(duì)結(jié)果精度的提升最為顯著。研究成果可以為其他無人機(jī)航測(cè)任務(wù)提供參考。
[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.
