High resolution fully 3-D mapping of human surfaces by laser array camera and data representations

Abstract

A 3-D surface is mensurated by active triangulation: an electro-optically controlled laser camera projects an array of beams onto the surface, and an optical camera detects the reflected images from a different perspective. By controlling the projection of the rays in a binary pattern mode, it is possible to correlate automatically the surface positions illuminated by the active camera and observed by the passive camera, and thus achieve the rapid triangulation of multiple surface points in three dimensions. The present implementation technique is discussed in comparison with other data acquisition methods. After an entire body surface is mensurated by multiple perspectives around the body, a volumetric representation is generated. Some examples are displayed using computer graphics.
