Abstract
In this paper we present prototype cultural heritage virtual reconstruction method by extracting three color pattern projected on objects surface. With rising accessibility to projecting devices and digital cameras new possibilities have risen. We focused on automatizing active range scanner techniques with assumption to move pattern and not any of the scene elements including both object and devices. Our goal was to acquire detailed point cloud for further reconstruction by determining shape of pattern lines. Results show that with use of difference images, low-pass signal filters and line thinning methods a detailed high poly model can be obtained even without refining point cloud.
