Systems and methods for adjusting lighting of a part based on a plurality of selected regions of an image of the part

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 that image quality. Portions of the image are extracted based on the defined regions of interest. The image quality of the captured image is determined based on an analysis of the regions of interest and the image quality defined in the multi area image quality tool.
