Abstract
A model containing a plurality of model edges is acquired, and a position that matches the model is searched for within a search image. Within the search image, a plurality of edge extraction regions including the respective plurality of model edges when the model is moved to the position searched for are set, and an arithmetic operation of extracting an edge in each of the plurality of edge extraction regions is performed. If there is an edge extraction region where no edge has been able to be extracted, of the model moved to the position searched for, a model edge located in the edge extraction region where no edge has been able to be extracted is incorporated into an edge set, and fitting is performed to the edge set.
