Machine vision lighting.

Vision lighting is the key to creating all important contrast between the feature of interest and its background. Lighting is one of the most critical aspects of machine vision applications. However some objects have 3d aspects that make accurately identifying surface defects more difficult. A lighting technique involves a light source and its placement with respect to the part and the camera.

For many surfaces simple defects such as scratches and dents are easily identifiable with a machine vision camera and a traditional lighting solution. Failure to properly illuminate a target can result in the loss of information and productivity. The main reason is that improper illumination results in loss of information which in most cases cannot be recovered via software. The llg660 generates a high quality uniform laser line making it especially suitable for machine vision applications.

The selection of the appropriate lighting component for a specific application is very important to ensure that a machine vision system performs its tasks consistently and reliably. It is well understood that the quality and appropriateness of lighting are critical aspects for creating a quality robust and timely vision inspection.

A practical guide to machine vision lighting abstract. Smart vision lights is the leading designer and manufacturer of led lighting solutions for any type of machine vision or automation camera application. Our innovative products were first to feature universal internal current control drivers offering constant on strobed operation reducing cost simplifying wiring requirements and making. Many lightings are developed over the years to address the different requirements of vision application based on various lighting geometry wave length and intensities.

The lighting sources now commonly used in machine vision are fluorescent quartz halogen led metal halide mercury and xenon. In addition to an understanding of illumination types and techniques geometry filtering sensor characteristics. Fluorescent quartz halogen and led are the most widely used lighting types in machine vision particularly for small to medium scale inspection stations. The pre requisite to good vision is the right light.
