Three-dimensional image acquisition system

Abstract

The invention provides a three-dimensional image acquisition system. The LED light source and the camera which are mutually spaced are arranged on the bracket which is arranged around the photographedobject; a polarizer is mounted on the camera; the polarization angle of the polarizer is adjusted, the three-dimensional image acquisition system can shoot a set of shot object three-dimensional photo data with left-handed circularly polarized light and a set of shot object three-dimensional photo data with right-handed circularly polarized light; the obtained two sets of photo data are importedinto image-based modeling software to carry out texture and polygon modeling; a set of non-highlight texture images and a set of highlight texture images can be obtained; the specular texture image can be obtained by taking the highlight texture image as the normal image and taking the non-highlight texture image as the diffuse image according to the formula of normal-diffuse=specular, so that themanufacturing period is greatly shortened, and the labor cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of image acquisition, in particular to a three-dimensional image acquisition system. Background technique [0002] In the process of 3D graphics rendering and image generation, it is necessary to assign surface texture images to the 3D model. The optical information of the texture image material obtained by the general method all contains the highlight component (specular reflection), but the texture material used in the three-dimensional graphics rendering process needs to separate the highlights to obtain diffuse and specular reflections. ) Two kinds of image materials, otherwise the rendering result is unreal and incorrect. [0003] At present, the method of separating the highlights in the image is manually removed by image processing software. This method of making texture image materials without highlights (specular reflection) depends to a large extent on the skills of the production staff, and in some case...
