Simulace vlastností objektivu

Abstract

Algoritmy počítačového vidění typicky zpracovávají snímky získané fotoaparátem nebo kamerou. Tyto snímky obsahují nedokonalosti, které jsou způsobeny konstrukcí objektivu. Táto práce se věnuje popisu simulace, která upravuje počítačem generované snímky 3D generovaného světa na snímky, které simulují výstup konkrétního fotoaparátu. Popisovaný algoritmus umožňuje simulovat geometrické zkreslení, chromatickou aberaci, efekt hloubky ostrosti, pohybové rozostření, vinětaci a odlesky. Simulátor taktéž umožňuje simulovat adaptaci aperturní clony v objektivu.

Computer vision algorithms typically process real world image data acquired by cameras or video cameras. Such image data suffer from imperfections cause by the acquisition process. This paper focuses on simulation of the acquisition process on simulation of the acquisition process in order to enable rendering of images based on a 3D generated model. Imperfections, such as geometry distorion, chromatic aberration, depth of field effect, motion blur, vignetting and lens flare are considered.
