Abstract
A system includes a first light source that emits a beam of light; an electrical modulator that imparts a time-varying modulation on the beam of light; a beam-shaping system that shapes the beam of light and projects the shaped beam of light onto an object; an image sensor that captures the beam of light reflected from the object; and processors that determine three-dimensional (3D) coordinates of points on the object.
Claims17
A system comprising:
- a first light source operable to emit a beam of light;
- an electrical modulator operable to impart a time-varying modulation on the beam of light;
- a beam-shaping system operable to shape the beam of light into a line of light and to project the line of light onto an object;
- an image sensor operable to capture the line of light reflected from the object;
- at least one processor operable to determine three-dimensional (3D) coordinates of points on the object based at least in part on the reflected line of light captured by the image sensor;
- and
- an accessory device having a processor for receiving image data from the system over an Ethernet cable and in response determining additional 3D coordinates of points on the object based on the image data, the accessory device further sending electrical power over the Ethernet cable to the system.
