Claim One:
1. A system for obtaining data representing surface points of an object, said system comprising: a sensing device having a pattern projector for providing a projected pattern on a surface of said object, at least one basic camera for acquiring basic 2D image data representing a basic 2D image of at least a portion of said object at a basic resolution, and a characteristic camera for acquiring characteristic image data representing a characteristic image of at least a portion of said object, said characteristic camera being at least one of a texture camera and a high resolution camera, said texture camera being a camera adapted to capture characteristic texture information about said portion of said object, said high resolution camera being a camera adapted to capture high resolution information about said portion of said object at a high resolution, said high resolution being higher than said basic resolution, said projected pattern being apparent on said basic image, a spatial relationship of said basic camera, said pattern projector and said characteristic camera in a sensor coordinate system being known; a basic image processor for extracting, from said basic 2D image data, 2D point data representing at least one set of 2D surface points provided from a reflection of said projected pattern on said surface; a 3D surface point calculator for calculating a set of 3D surface points in said sensor coordinate system using said 2D point data representing set of 2D surface points; a characteristic image processor for mathematically projecting said set of 3D surface points onto said characteristic image data to obtain a location of said 3D surface points in said characteristic image data and for extracting characteristic data for said set of 3D surface points at a short distance from said projected 3D surface points in said characteristic image data.
