Structured Light Scanner Triangulation

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.

Structured light scanner triangulation.

The same technique used for thom s face in the radiohead house of cards video. In this article we explore the two main technologies used for 3d scanning for 3d printing in other words laser triangulation and structured light. Just as with other 3d scanning technologies structured light 3d scanning is based on the concept of triangulation. Structured light 3d scanning.

3d scanning can be based on different technologies each with their own benefits limitations. Nevertheless 3d scanning technology offers distinct advantages compared to traditional touch probe measurements. Configuring a structured light sensor for a specific application is in some respects a simple process. 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. 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. So how do laser scanners compare to structured light scanners. 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.

The target object is stationary.
