CLOTH IMAGE PROCESSING SYSTEM AND CLOTH IMAGE PROCESSING METHOD

PROBLEM TO BE SOLVED: To provide a cloth image processing system which raises accuracy of reproducing a texture in the curved surface area of dress and ornaments higher than the conventional art and provides an image of the dress and ornaments having almost the same level as an actual one to a consumer.SOLUTION: The cloth image processing system comprises: a luminance value function generation unit for generating, from the reflected light intensity that corresponds to the correlation of an observation viewpoint per curvature and an irradiation direction of a light source acquired from a cloth having a plurality of known different curvatures, a luminance value calculation function for calculating a luminance value based on the observation viewpoint in each of the curvatures of the cloth and the irradiation direction of the light source; a three-dimensional shape generation unit for generating a virtual three-dimensional shape of a cloth product by computer graphics; a curvature extraction unit for extracting the average curvature of shape pixels being the pixels in the three-dimensional shape; a function selection unit for selecting a luminance value calculation function for a curvature that corresponds to the average curvature; and a luminance value calculation unit for calculating the luminance value of shape pixels by the luminance value calculation function.SELECTED DRAWING: Figure 1 【課題】服飾品の曲面の領域における質感の再現の精度を従来に比較して高くし、消費者に対して実際と同程度の服飾品の画像を提供する布地画像処理システムを提供する。【解決手段】本発明の布地画像処理システムは、既知である複数の異なる曲率を有する布から取得した、曲率毎の観察視点と光源の照射方向との相対関係に対応した反射光強度から、布の曲率各々における観察視点及び光源の照射方向に基づいた輝度値を算出する輝度値算出関数を生成する輝度値関数生成部と、コンピュータグラフィックスにより、布製品の仮想の３次元形状を生成する３次元形状生成部と、３次元形状における画素である形状画素の平均曲率を抽出する曲率抽出部と、平均曲率に対応する曲率の輝度値算出関数を選択する関数選択部と、形状画素の輝度値を輝度値算出関数により算出する輝度値算出部とを備える。【選択図】図１
