カメラ特性を再現するカメラシミュレータの構築と簡便なパラメータ取得手法の提案

抄録

In this paper, a camera simulator that simulates camera properties and simple methods to obtain its parameters are proposed. The camera simulator simulates distortion, limb darkening, blur by defocus, blur by aberration, motion blur, variation of pixel sensitivity, random noise, gamma correction, and salt and pepper noise. As for methods to obtain camera parameters, parameters of blur by aberration and distortion are obtained by getting an image of a stripe pattern, and parameters of limb darkening, variation of pixel sensitivity, random noise and salt and pepper noise are obtained by getting a number of images using a camera covered by a diffuser. Fundamental experiments show that the constructed Camera Simulator and the proposed methods to obtain camera parameters are effective.
