Vision imaging system having a camera and dual aimer assemblies

Abstract:

A vision system for imaging feature sets on an object surface, including a first imaging system having at least a first image sensor and first optics, the first imaging system defining a standard, on-axis configuration having a system optical axis. A second imaging system defines an extended-depth of focus (DOF) configuration with second optics. A vision system processor receives and processes image data from the first imaging system and the second imaging system. A primary aimer assembly and a secondary aimer assembly that each project a discrete beam of structured light onto the surface in a relative relationship that indicates a focus distance with respect to the first imaging system and indicates an approximate center of the field of view of the second imaging system.
