Structured Light Scanner Triangulation

Structured light 3d scanning.

Structured light scanner triangulation. 3d scanning can be based on different technologies each with their own benefits limitations. For sub micron applications led structured light sensors are preferred since laser triangulation sensors produce laser speckle that prevents scanning at the sub micron level. Configuring a structured light sensor for a specific application is in some respects a simple process. Nevertheless 3d scanning technology offers distinct advantages compared to traditional touch probe measurements.

The same technique used for thom s face in the radiohead house of cards video. The target object is stationary. 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. So how do laser scanners compare to structured light scanners.

I ll walk you through setting up your projector and camera and capturing images that can be decoded into a 3d point cloud using a processing application. Projecting a narrow band of light onto a three dimensionally shaped surface produces a line of illumination that appears distorted from other perspectives than that of the. At present laser triangulation scanners structured light and contact scanning are the predominant technologies employed for industrial purposes with contact scanning remaining the slowest but overall most accurate option. The concept of triangulation.

By emitting a beam of light on any single point of an object and taking three measurements of the point including distance and angle the exact position of the point space can be determined.
