As industry expectations for automation and measurement accuracy increase, more applications are benefitting from 3D machine vision techniques over simpler 2D measurement systems to enable reliable decision-making. For example, inline automated optical inspection (AOI) can identify defective parts in a production line so they can be routed for rework or scrapped earlier, saving time and money and increasing product quality. Introducing z-dimension data enables fewer false fails and can measure geometries not captured by 2D systems. Other example 3D machine vision applications include factory automation use cases such as pick-and-place systems or robotic arms, inline metrology, solder paste inspection, and biometrics.
Structured light is one of the top 3D machine vision techniques that combines a light pattern generator with an optical sensor such as a camera. DLP technology is used in structured light systems to provide fast, flexible and highly programmable light patterns, resulting in 3D measurements with millimeter or even micron-level accuracy. This webinar will cover system considerations as well as TI DLP® Products for structured light solutions.
