Machine Vision Lighting Fundamentals

For inspection of moving or non moving parts strobe lighting can offer unsurpassed advantages over other types of lighting.

Machine vision lighting fundamentals. For example whereas led lighting has a longer life expectancy quartz halogen lighting may be the choice for a particular inspection because it offers greater intensity. The lens may cause the specular reflection to disappear completely. 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. The usual desired output is data that is used to make an inspection decision or to permit a comparison with other data.

Machine vision hardware components a machine vision system con sists of hardware and software components. The basic hardware components are a light source a solid state camera and lens and a vision processor. One area that is often neglected in machine vision applications is lighting considerations. Types of reflection specular reflection diffuse reflection.

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. 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. 2 comparison and contrast of common vision lighting sources.

Light flows from source to image figure 12. Unless these angles are well controlled it is best to avoid depending. Machine vision lighting fundamentals light source object lens and camera figure 11. The fundamentals of machine vision part 1.

And has to be tolerated by the machine vision system such as changing lighting conditions or foreign objects. Machine vision fundamentals outline and principles this is the first in a series of articles intended to provide a short introduction to. The in sight integrated light is a diffuse ring light that provides bright uniform lighting on the target for machine vision applications. Due to the diffuse nature of the light at closer working distances less than 70mm the light also provides a.
