HALCON Application for Shape-Based Matching

Shape-based matching is mainly emphasized in this paper for actual wokpiece applications based HALCON, a new machine vision software. First a measuring ROI, i.e., the region of interest is determined to create a model. Then the matching and locating of the search object is achieved by using affine transform. Experiment result indicates that this method can find objects starting based on a single model image and localize objects with subpixel accuracy.
