<p>PROBLEM TO BE SOLVED: To provide a system and method for obtaining images with offset utilized for enhanced edge resolution.SOLUTION: In a method in a machine vision inspection system for obtaining two images of a workpiece with a desired sub-pixel offset between the images, the images are acquired using a fast multiple image acquisition operation mode of a camera in the machine vision inspection system. In various implementations, the method includes removing the offset between the images, and therefore the workpiece is congruent in the images, and congruent image data is combined. The combined image data has a resolution better than that allowed by the native resolution of the camera that acquires images in the machine vision inspection system. The method may be implemented in an edge feature video tool for measuring edge features on the workpiece. A motion direction utilized for obtaining the two images may be made to be transverse to the edge direction of an edge that is being measured.</p> |
