Over the past few years, 3D machine vision has rapidly gained popularity in manufacturing - and for good reason. 3D vision provides a robust solution for inspection and measurement where 2D data has fallen short due to misalignment, glare, or lack of contrast.
There are a few technologies used to create 3D images for inline inspection, but the two most common are pattern projection using structured light and laser profilers. The best 3D vision system for an application will depend on many factors including line speed, part size, or accuracy requirements. Below is some information to get you started, but if you have any questions you can request a free consultation with a local vision expert.
