Three dimensional log scanning device for a log positioning and saw system

摘要

A scanning device for determining the shape of irregular substantially cylindrical objects. Lines of light are projected onto the surface of the object. The position of the images of the lines on the surface are measured at predetermined positions to obtain a three dimensional profile of the object. The device can be incorporated into a log cutting system and the position of the log can be adjusted based on the profile determination to obtain maximum yield from the log.
