3D Laser Triangulation

Laser based 3D scanners use a process called trigonometric triangulation to accurately capture a 3D shape as millions of points. Laser scanners work by projecting a laser line or multiple lines onto an object and then capturing its reflection with a single sensor or multiple sensors.

Types of 3D Scanners and 3D Scanning Technologies:

Short Range 3D Scanners Short Range 3D scanners typically utilize a Laser triangulation or Structured Light technology.

Benefits of 3D Laser Scanners:

• Able to scan tough surfaces, such as shiny or dark finishes
• Less sensitive to changing light conditions and ambient light
• Often more portable
• Simpler design – easier to use and lower cost
