ABSTRACT:
A method and apparatus for measuring the dimensions and determining the three-dimensional, spatial volume of objects, particularly small objects. Reflected laser light sensors are employed. A stationary measurement embodiment of the apparatus may be employed to measure regular cuboidal objects. A dynamic or in-motion embodiment may be employed to measure the dimensions of cuboidal objects or a three-dimensional outline of objects of irregular configuration.
