REGISTRATION METHOD FOR MODEL DATA FOR OPTICAL RECOGNITION PROCESSING, AND OPTICAL SENSOR

PROBLEM TO BE SOLVED: To easily generate model data having high recognition accuracy and being consistent with the installation environment of each of optical sensors and measurement conditions. SOLUTION: A basic model representing a range in which a workpiece can be optically recognized is input, and pieces of processing of imaging and measuring the workpiece under the same condition as that in an actual measurement and matching the feature data of the workpiece obtained from this measurement with the basic model are executed for a plurality of number of cycles. Then, in the basic model, information is set as unnecessary information where the information cannot be associated with the feature data of the workpiece in all of the pieces of matching processing, or where the number of times or ratio the information cannot be associated is more than a predetermined reference value, or where the information cannot be associated with the feature data in any one of the pieces of executed matching processing. Then, the unnecessary information is deleted from the basic model, and information after each deletion is identified as model data to be registered and is registered to the memory.
