SUMMARY

The optical system of a structured light 3D scanner operates by projecting a series of light patterns onto the object being scanned. The deformation of these patterns, captured by cameras, allows for the calculation of the Z coordinate through triangulation. This method enables precise depth measurement and creates a detailed 3D representation of the scanned object. Tools like the Artec 3D scanner utilize this technology to enhance scanning accuracy and efficiency.

PREREQUISITES
  • Understanding of triangulation principles in 3D scanning
  • Familiarity with optical systems and light projection techniques
  • Knowledge of structured light scanning technology
  • Basic concepts of 3D modeling and representation
NEXT STEPS
  • Research the principles of triangulation in 3D scanning
  • Explore the functionality of Artec 3D scanners
  • Learn about optical systems used in structured light scanning
  • Investigate software tools for processing 3D scan data
USEFUL FOR

Engineers, 3D scanning professionals, and anyone interested in understanding the mechanics behind structured light 3D scanning technology.

Hello, can anyone explain me how optical system of a structured light 3d scanner like this one works? I tried to google it, but still didn't understand how it get's Z coordinate.

Welcome to the PF. :smile:

That same website has more information on how to do the 3-D scans...
