Understanding 3D Scanning Technologies

Before discussing integration, it is essential to understand how 3D scanning captures physical geometrie. Three primary technologies dominate thee market: laser triangulation, structured light, andd contrimmetry. Each has distinct t pretts, crisacy levels, and typical applications.

Laser Triangulation

Laser scanners project a laser line onto an object and use cameras to o triangulate thee reflecte light, generating a dense point cloud. These scanners are widely used for industrial metrology because they offer high clicacy (0,01- 0,05 mm) over medium tem large parts. They perfom well on matte surfaces but strugle with reflective or transparent materials.

Structured Light

Structured lights systems project a series of planet light grids onto thee object. Distortions in the Patterns are captured by cameras andd decoded intro 3D coordinates. These scanners are faset and often used for slaller objects, accesing g custiacy similar to laser scanners. They are sensitivy to ambient ligt and require calibration, but they excel at capturintricate surface detales and color texture.
