LASER ENHANCED RECONSTRUCTION OF 3D SURFACE

摘要

A method for reconstructing a surface of a three-dimensional object (41) involves a projection of a laser spot pattern (12, 14) onto the surface of the three-dimensional object (41) by a laser (11), and a generation of a series of endoscopic images (24) as an endoscope (21) is translated and/or rotated relative to the three-dimensional object (41). Each endoscopic image (24) illustrates a different view (23) of a laser spot array (13, 15) within the laser spot pattern (12, 14) as projected onto the surface of the three-dimensional object (41) by the laser (11). The laser spot array (13, 15) may be identical to or a subset of the laser spot pattern (12, 14). The method further involves a reconstruction of the surface of the three-dimensional object (41) from a correspondence of the different views (23) of the laser spot array (13, 15) as illustrated in the endoscopic images (24).
