Computer Description of Curved Objects
April 1976 (vol. 25 no. 4)
pp. 439-449
G.J. Agin, Stanford Research Institute
A ranging system, consisting of a laser, computer-controlled optical deflection assembly, and TV camera, obtains three-dimensional images of curved solid objects. The object is segmented into parts by grouping parallel traces obtained from the ranging system. Making use of the property of generalized translational invariance, the parts are described in terms of generalized cylinders, consisting of a space curve, or axis, and a circular cross section function on this axis.
Index Terms:
Computer vision, recognition of curved objects, three-dimensional imaging.
