Method and apparatus for reconstructing three-dimensional surfaces from two-dimensional images

摘要: A method and apparatus for reconstructing the surface, i.e third dimension, of a three-dimensional object from two-dimemsional information includes projecting radiant energy, such as light, substantially parallel ray source at said number different angles relative to reference surface with respect which is placed. The lengths locations shadows cast by are measured function angle light rays. location determined shadow respective created. Preferably, an electronic camera that generates electrical signals indicative image. These preferably received computer determines surface. also controls position energy source. relatively insensitive variations in measurement signal processing conditions. produced applying may be used many applications, example, positioning robot gripper retrieve part bin.
