Abstract
A method and apparatus for measuring the dimensions and determining the three-dimensional, spatial volume of objects. An object detection system is employed to detect proper placement of an object to be measured, and waveguides are employed as standoffs and received wave isolators for reflected-wave sensors. An autocalibration method for ultrasonic sensors is also disclosed.
