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. Types of reflection specular reflection diffuse reflection. It is the automatic acquisition and analysis of images to obtain desired data for controlling or. 2 comparison and contrast of common vision lighting sources.

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 in sight integrated light is a diffuse ring light that provides bright uniform lighting on the target for machine vision applications. The objective of this article is to familiarize the reader with some of the techniques used in strobe light imaging with. Machine vision lighting fundamentals light source object lens and camera figure 11.

Unless these angles are well controlled it is best to avoid depending. One area that is often neglected in machine vision applications is lighting considerations. Light flows from source to image figure 12. 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.

And has to be tolerated by the machine vision system such as changing lighting conditions or foreign objects. This integrated light reduces shadowing and provides uniform illumination on matte objects. 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. The basic hardware components are a light source a solid state camera and lens and a vision processor.
