This is in contrast to a laser scanner which emits multiple laser dots on the object one after the other.
Structured light 3d scanner.
A structured light 3d scanner is a 3d scanning device for measuring the three dimensional shape of an object using projected light patterns and a camera system.
A structured light 3d scanner is a type of 3d scanner that uses the following components to capture 3d scans.
Structured light 3d scanners versus laser 3d scanners they are both optical 3d measurement devices that uses light based measurement techniques to capture a 3d scan.
The capturing unit is the physical part of the scanner that consists of a projection light source white light blue led light and typically 1 or 2 camera s.
Projecting a narrow band of light onto a three dimensionally shaped surface produces a line of illumination that appears distorted.
3d scanning technology that brilliantly captures reality in a matter of seconds capture reality with hp s new 3d scan solution.
What is structured light 3d scanning.
Structured light scanning is a 3d scanning technology that uses a single light source that projects multiple lines on the object all of which are tracked simultaneously by a camera or multiple cameras.
This technology also uses trigonometric triangulation but works by projecting a pattern of light onto the object to scan and not a laser line or dot.
Technology benefits and limitations.
