지방사진 측량의 렌즈 왜곡보정 모델 개발 = A development of lens distortion Correction model of Terrestrial Photogrammetry

다국어 초록 (Multilingual Abstract)

It may contain an error of lems distortion that photogrammetry on the basis of film taping a photograph of an object.
In order to elevate precision in metric photos, search the model using non-metric photos in photogrammetry, the method of error correction due to lens distortion was reserched in this paper.
The results of experimental analysis, in the case of symmetrical and asymmetrical lens distortion was, in the case of the metric photos, the error was minimized by the distortion coeficient K₁, in Symmetrical lens distortion.
In the case of non-metric photos, the error was minimized by the distortion coeficient K₁, K₂ and K₃ of symmetrical lens distortion and P₁ and P₂ of asymmetrical lens distortion.
By using the equation of correction as follows the validity of non-metric was verified in close Range Photogrammetry.
Δx=x(K₁r²+k₂r⁴+k₃r^6)+P₁(r²+2x²)+2p₂xy
Δy=y(k₁r²+k₂r⁴+k₃r^6)+P₁(r²+2x²)+2p₂xy
