Three-dimensional imager

Abstract

A three-dimensional (3D) measuring system and a method of determining a distance is provided. A three-dimensional (3D) measuring system includes a projector operable to project a pattern of light onto an object. A camera is operable to image the projected pattern of light. An electrical power distribution network is operable to receive alternating current having a line frequency. A control system is operable to set an exposure time of the camera to a positive integer divided by twice a line frequency. A processor is operable to determine three-dimensional (3D) coordinates of a point on the object based at least on the projected pattern of light and on the imaged pattern of light.
