Paper Abstract

In this paper a 3D shape measurement system with additional color and angular reflectance measurement capabilities is presented. The shape measurement system is based on structured light projection with the use of DLP projector. 3D shape measurement method is based on sinusoidal fringes and Gray codes projection. The color measurement system uses multispectral methods with a set of interference filters to separate spectral channels. Additionally the setup includes an array of compact light sources for measuring angular reflectance based on image analysis and 3D data processing. All three components of the integrated system use the same grayscale camera as a detector. The purpose of the system is to obtain complete information about shape, color and reflectance characteristic of measured surface, especially for cultural heritage objects in order to use in documentation, visualization, copying and storing. Some measurement results of real objects with a discussion of accuracy are presented along with future development plans.
