Workpiece display assistance device, workpiece display assistance method, and workpiece display assistance program

A workpiece display assistance method comprising:

• obtaining, by a first model generation unit, shape data of a workpiece to be set, and generating an original model of the workpiece based on the shape data;
• generating, by a second model generation unit, a plurality of matching models by rotating and/or inverting the original model;
• matching, by an extraction unit, each of the plurality of matching models to the original model and extracting aligned portions of the respective matching models with the original model as matching sections;
• creating, by a model creation unit, a matching aggregate model by aggregating the matching sections extracted in a state conforming to the original model and synthesizing the matching sections;
• comparing, by a determination unit, the original model with the matching aggregate model and determining a feature point on the workpiece;
• and
• displaying, by a display unit, the feature point in a highlightable manner, along with an image of the workpiece, on a display screen of a display device based on a determination result of the determination.

A non-transitory, computer readable storage medium having stored thereon a workpiece display assistance program for causing a computer to execute:

• obtaining, by a first model generation unit, shape data of a workpiece to be set, and generating an original model of the workpiece based on the shape data;
• generating, by a second model generation unit, a plurality of matching models by rotating and/or inverting the original model;
• matching, by an extraction unit, each of the plurality of matching models to the original model and extracting aligned portions of the respective matching models with the original model as matching sections;
• creating, by a model creation unit, a matching aggregate model by aggregating the matching sections extracted in a state conforming to the original model and synthesizing the matching sections;
• comparing, by a determination unit, the original model with the matching aggregate model and determining a feature point on the workpiece;
• and
• displaying, by a display unit, the feature point in a highlightable manner, along with an image of the workpiece, on a display screen of a display device based on a determination result of the determination.
