3D Laser Scanners

Provided by: ToolingU

A laser line scanner is a type of 3D optical measuring device used to record an object's geometry. Laser line scanners gather measurements by projecting a single or multiple laser lines onto an object while a camera captures its reflection. The scanned point data is used to construct a 3D model in real time. 3D laser line scanners are used for many applications in manufacturing, including inspection, GD&T analysis, and reverse engineering processes. After taking this class, users will be able to describe 3D laser line scanners and how they function.

Course Objectives:

  • Describe inspection methods used in manufacturing
  • Distinguish between laser and structured light scanning
  • Describe laser line scanners
  • Describe 3D laser line scanner applications
  • Distinguish between different laser light colors
  • Distinguish between single-line and multiple-line scanners
  • Distinguish between flying dot principle and solid beam principle
  • Describe how laser scanners function
  • Describe 3D laser line scanner data collection and analysis
  • Describe how laser line scanners are integrated with other components
  • Describe how 3D scanning is used in smart manufacturing.

Recommended Background

  • Recommended for manufacturing personnel, particularly for the quality control and inspection department.
