Abstract
Cieľom diplomovej práce je poukázať na digitalizáciu historických textílii ako na ?kultúrne dedičstvo?. V prvej časti tejto práce sú popísane základné teoretické poznatky vzťahujúce sa ku skúmanej problematike v oblasti kolorimetrie so zameraním na digitálne systémy záznamu obrazových dát. Teória sa predovšetkým orientuje v oblasti farebných modelov, miešaniu farieb a vzniku farebného vnemu, kde sa podieľajú tri základné faktory. Ďalej je v práci popísaná správa farieb pre zariadenia a taktiež bezkontaktné meranie pri digitalizácii alebo pred samotným reštaurovaním diela a stručný prehľad o historických textíliách a ich reštaurovaní. V experimentálnej časti sa diplomová práca zaoberá vplyvom osvetlenia na kolorimetrické parametre finálneho obrazového záznamu vzniknutom na snímači, pri opakovanom meraní. Detailné popísanie použitých zariadení a podmienok za akých bolo hodnotenie prevádzané. A následná kolorimetrická analýza výskytu jednotlivých odtieňov v systéme CIE LAB na historických textíliách. V úplnom závere diplomovej práce sa nachádza vyhodnotenie výsledkov.
The objective of this thesis is to present the digitalisation of historic textiles as the cultural heritage. In the first part of this work is described the basic theoretical knowledge related to examined issues in the field of colorimetry with the focus on digital image data recording systems. The theory is primarily focused on area of color models, the color perception's origin which involves three basic factors and mixing colors. Additionally, my work includes the subject of Color management devices as well as non-contact measurement in digitalization or before the actual restoration work; and a brief overview of historic textiles and their restoration. The experimental part of the thesis deals with the impact of lighting on colorimetric indicators of the final video record observed on the sensor, with repeated measurements. Detailed description of used equipments and the conditions under which the evaluation was conducted. Subsequent colorimetric analysis of different colors occuring in the CIE LAB system on historic textiles. The final part of my diploma work contains the evaluation of the results.
