Alignment system, alignment method, and recording medium

An alignment system, comprising:

• an image processor to detect, from a captured image of a workpiece including an identification target, the identification target through a rough search and a fine search different from each other;
• an operation controller to control, based on actual coordinates of the identification target detected by the image processor, a driver to move the workpiece;
• and
• a setting terminal for performing a setting on the image processor,
• wherein detecting the identification target by the image processor and controlling the driver by the operation controller are performed repeatedly,
• the fine search is performed on a search range narrower than a range for the rough search, and when the identification target is detected through the fine search, the image processor performs, as a next search, the fine search without performing the rough search,
• the rough search includes pattern matching to perform matching of a pattern included in the workpiece and a pattern model preregistered by the setting terminal, and
• the fine search is performed using search logic for the fine search that is generated by the setting terminal in registering the pattern model to be used in the pattern matching in the rough search based on a shape of the pattern model.
