Structured-light 3D scanner Application

Applications

Industrial Optical Metrology System (ATOS) utilizes structured light technology for highly accurate and scalable measurements. These systems feature self-monitoring for calibration status, conversion accuracy, environmental changes and part movement to ensure high-quality measurement data.Google Project Tango SLAM (Simultaneous Localization and Mapping) uses depth techniques including structured light, time-of-flight and stereo.Time-of-flight requires the use of an infrared (IR) projector and IR sensor; the stereo does not.3D scanners from MainAxis srl use advanced patented technology for full color 3D scanning with acquisition times of a few microseconds for medical and other applications.

A technology from PrimeSense, used in earlier versions of the Microsoft Kinect, that uses projected patterns of infrared dots to generate dense 3D images.(Later, the Microsoft Kinect switched to a time-of-flight camera instead of structured light.)·The structure sensor uses a pattern of projected infrared dots, calibrated to minimize distortion to generate a dense 3D image.

• Structure Core uses stereo cameras to match random patterns of projected infrared dots to generate dense 3D images.

• The Intel RealSense camera projects a series of infrared patterns to obtain 3D structures.

• The Face ID system works by projecting over 30,000 infrared points onto the face and generating a 3D facial map.

• The VicoVR sensor uses infrared point patterns for skeletal tracking.

• Chiaro Technologies uses a single engineered infrared point pattern called Symbolic Light to stream 3D point clouds for industrial applications
