Structured-light 3D scanner
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.
Pronunciation
- Structured-light: /ˈstrʌktʃərd laɪt/
- 3D scanner: /ˈθriː diː ˈskænər/
Etymology
The term "Structured-light 3D scanner" is derived from the technology it uses. "Structured-light" refers to the method of projecting a known pattern of pixels (often grids or horizontal bars) onto a scene. The way that these patterns deform over the surfaces allows the system to calculate the depth and surface information of the objects in the scene, as used in 3D scanning.
Related Terms
- 3D scanning: The process of analyzing a real-world object or environment to collect data on its shape and possibly its appearance.
- Photogrammetry: The science of making measurements from photographs, especially for recovering the exact positions of surface points.
- Laser scanning: A method of collecting surface data or measuring building structures using a laser scanner.
- Computer vision: An interdisciplinary scientific field that deals with how computers can gain high-level understanding from digital images or videos.
Usage
Structured-light 3D scanners are used in various applications such as healthcare, entertainment, and industrial design where precise measurements are required. In the medical field, these scanners are used for creating prosthetics, studying body movement, and for surgical planning.
