Method for constructing three-dimensional model to scan e.g. casing of statue, involves projecting structured luminous pattern on surface, acquiring stereoscopic images of surface, and constructing scanning model from images

摘要

The method involves projecting a structured luminous pattern on a surface with respect to orientation of a scanner. Stereoscopic images of the surface are acquired by acquiring images quadruplet, where the images quadruplet comprises a pair of structured bi-dimensional stereoscopic images of the surface and a pair of textured bi-dimensional stereoscopic images. A scanning model is constructed from the images. Independent claims are also included for the following: (1) a computer program product comprising instructions for executing a method for constructing a three-dimensional model of a physical surface (2) a three-dimensional scanning system comprising a CPU.
