Abstract
The present invention relates to methods and apparatus for measuring the linear dimensions and determining the three-dimensional, spatial volume of objects. In the preferred embodiments, ultrasonic sensing is employed, alone or in combination with other measuring methods such as light curtains and the timing of moving objects, to ascertain linear dimensions. The preferred embodiments are particularly adapted to the measurement of large and irregularly configured objects, such as palletized loads, and to the measurement of moving, rectangular objects of random orientation with respect to the direction of travel.
