Abstract
The lighting behavior of a vision system is inconsistent between vision systems, within a vision system over time or between parts being viewed. This inconsistency makes it difficult to correctly run part programs even within a single run of parts on a single machine. The multi area image quality tool systems, methods and graphical user interfaces adjust the light intensity of a vision system to obtain a desired image quality or characteristic of a captured image. The multi area image quality tool is used to define a plurality of regions of interest within a captured image to be used to determine the image quality or characteristic of the captured image resulting from a current illumination level. The multi area image quality tool allows a user to easily and quickly define multiple regions of interest that can be used to determine the image quality of a captured image. The multi area image quality tool allows the user to specify the location, orientation and size of two or more regions of interest around a critical feature of the captured image, and to specify the light sources to be used to illuminate the part, the image quality to be measured, and a range of acceptable values for…
