Abstract

Multiple lines of laser light can be used in machine vision, as an illumination source for three-dimensional vision, for part registration, detecting and determining proper placement of parts against low-contrast backgrounds, gauging parts with complicated geometries, and situations currently employing a single line of light illumination. Using multiple lines of laser light in conjunction with an electronic image processor can produce real-time part registration and inspection. This technique has also been used to show part deflection or distortion in real time. This paper describes how to generate and project multiple lines of laser light and how to use these lines in machine vision.
