A method and apparatus for measuring the length, width, and height of rectangular solid objects moving on a conveyor. The apparatus includes a light curtain, two laser triangulation range finders, and a pulse tachometer mounted on a frame around a conveyor. As an object is conveyed through the frame, measurements from each of the sensors are correlated by a digital computer to estimate the length, width and height of the object. The method and apparatus does not require a break in the surface of the conveyor, and is insensitive to object placement and orientation on the conveyor.

Abstract

A method and apparatus for measuring the length, width, and height of rectangular solid objects moving on a conveyor. The apparatus includes a light curtain, two laser triangulation range finders, and a pulse tachometer mounted on a frame around a conveyor. As an object is conveyed through the frame, measurements from each of the sensors are correlated by a digital computer to estimate the length, width and height of the object. The method and apparatus does not require a break in the surface of the conveyor, and is insensitive to object placement and orientation on the conveyor.
