POINT CLOUD MERGING FROM MULTIPLE CAMERAS AND SOURCES IN THREE-DIMENSIONAL PROFILOMETRY

摘要

A computer-implemented method of and system for measuring a three-dimensional surface are provided. The method includes projecting structured illumination on the surface and acquiring a plurality of sets of images. The sets of images are processed to obtain a plurality of point clouds. A spatial accumulator is defined. A first point cloud of the plurality of point clouds is combined with a second point cloud of the plurality of point clouds into the spatial accumulator. Spatial coordinates of the surface are generated based on the contents of the spatial accumulator.

1. A computer-implemented method of measuring a three-dimensional surface, the method comprising:
projecting structured illumination on the surface and acquiring a plurality of sets of images; processing the sets of images to obtain a plurality of point clouds; defining a spatial accumulator that is configured to receive point cloud information in each element of the spatial accumulator; combining a first point cloud of the plurality of point clouds with a second point cloud of the plurality of point clouds into the spatial accumulator; and generating spatial coordinates of the surface based on the contents of the spatial accumulator.
