How Does a Structured Light 3D Scanner Work?
The process of 3D scanning using a structured light scanner involves several steps:
1 – Light Projection:
The scanner projects structured light, typically in the form of line or dot patterns, onto the surface of the object to be scanned. These light patterns create shadows and deformations on the object’s surface based on its geometry.
2 – Image Capture:
One or more cameras are used to capture the image of the object with the projected light. The cameras record deformations and variations in the light patterns resulting from the object’s shape.
