Machine Vision Lighting Fundamentals

One area that is often neglected in machine vision applications is lighting considerations.

Machine vision lighting fundamentals.

What is machine vision machine vision is the substitution of the human visual sense and judgment capabilities with a video camera and computer to perform an inspection task. Light flows from source to image figure 12. The lens may cause the specular reflection to disappear completely. For inspection of moving or non moving parts strobe lighting can offer unsurpassed advantages over other types of lighting.

The usual desired output is data that is used to make an inspection decision or to permit a comparison with other data. Types of reflection specular reflection diffuse reflection. Machine vision hardware components a machine vision system con sists of hardware and software components. The fundamentals of machine vision part 1.

It is the automatic acquisition and analysis of images to obtain desired data for controlling or. Due to the diffuse nature of the light at closer working distances less than 70mm the light also provides a. This integrated light reduces shadowing and provides uniform illumination on matte objects. One area that is often neglected in machine vision applications is lighting considerations.

Unless these angles are well controlled it is best to avoid depending. David dechow in this video series you ll learn all the basics including how images are captured and transferred to the computer the principles of lighting and the common processing algorithms used by machine vision systems. The basic hardware components are a light source a solid state camera and lens and a vision processor. The objective of this article is to familiarize the reader with some of the techniques used in strobe light imaging with.

Criteria as applied to machine vision. The in sight integrated light is a diffuse ring light that provides bright uniform lighting on the target for machine vision applications. Machine vision lighting fundamentals light source object lens and camera figure 11. The advances in machine vision technology have been substantial in recent years with the introduction of faster more powerful processors and the improvements in sensor technology i e solid state cameras.
