Machine Vision 101

Hermary manufactures a suite of 3D scanners that form an integral part of machine vision systems. Machine Builders & System Integrators use Hermary scanners as a key component in a wide variety of solutions that deliver real value.

 

3D or 2D Machine Vision?

Manufacturers have two choices 3D or 2D machine vision, depending on application requirements. More recently manufacturers have embraced 3D machine vision to deliver accurate dimensional data, taking application capabilities to a new strategic level.

 

How do 3D Scanners Work?

Hermary scanners work on the principle of laser triangulation. A laser beam is projected at a known angle onto a target to be measured; a camera at a known offset from the laser views the projected image.

 

What is a Point Cloud?

3D Machine Vision captures the location and shape of an object in a format suitable for processing by a computer or a PAC/PLC.  An object’s surface is represented by a list of three-dimensional coordinates (X, Y, Z) which is referred to as a “Point Cloud”.

 

Why Class II Lasers?

Workplace safety is important to all. By design, all Hermary products are Class II (or Class IIM) laser rated.

 

What Can be Scanned?

Laser triangulation depends upon capturing a small amount of reflected energy in the imaging system. Most materials can be scanned using laser triangulation.
