Inspection apparatus and storage medium storing computer program

A non-transitory computer-readable storage medium storing a set of program instructions for an inspection apparatus, the inspection apparatus comprising a controller and a memory, the set of program instructions, when executed by the controller, causing the inspection apparatus to perform:

• acquiring drawing data indicating a drawing of a portion including a label affixed to a particular affix position of a product;
• identifying the label in the drawing based on the drawing data;
• identifying a position of a reference portion of the product in the drawing based on the drawing data, the reference portion being a portion serving as a reference for specifying the particular affix position of the label with respect to the product, the identifying the position of the reference portion including:
• identifying a first extension line in contact with the label in the drawing by analyzing the drawing data;
• and
• identifying a second extension line parallel to the first extension line and separated from the label in the drawing, the second extension line being located on the reference portion, thereby identifying the position of the reference portion of the product in the drawing;
• acquiring dimension information indicated in the drawing based on the drawing data, an identification result of the label in the drawing, and an identification result of the position of the reference portion in the drawing, the dimension information being information for specifying a positional relationship between the reference portion and the particular affix position, the dimension information including a tolerance of the particular affix position, the acquiring the dimension information including:
• identifying a numerical value associated with the first extension line and the second extension line by analyzing the drawing data;
• and
• acquiring the dimension information based on the numerical value;
• acquiring captured image data obtained by capturing an image of the product to which the label is affixed, a captured image indicated by the captured image data including a portion of the product including the label;
• identifying the label in the captured image based on the captured image data;
• identifying the reference portion of the product in the captured image based on the captured image data;
• and
• determining whether an affix position of the label in the captured image is the particular affix position specified by the dimension information, based on an identification result of the label in the captured image, an identification result of a position of the reference portion in the captured image, and the dimension information.

An inspection apparatus comprising:

• a controller;
• and
• a memory storing instructions, the instructions, when executed by the controller, causing the inspection apparatus to perform:
• acquiring drawing data indicating a drawing of a portion including a constituent part arranged at a particular arrangement position of an object;
• identifying the constituent part in the drawing based on the drawing data;
• identifying a position of a reference portion of the object in the drawing based on the drawing data, the reference portion being a portion serving as a reference for specifying the particular arrangement position of the constituent part with respect to the object, the identifying the position of the reference portion including:
• identifying a first extension line in contact with the constituent part in the drawing by analyzing the drawing data;
• and
• identifying a second extension line parallel to the first extension line and separated from the constituent part in the drawing, the second extension line being located on the reference portion, thereby identifying the position of the reference portion of the object in the drawing;
• acquiring dimension information indicated in the drawing based on the drawing data, an identification result of the constituent part in the drawing, and an identification result of the position of the reference portion in the drawing, the dimension information being information for specifying a positional relationship between the reference portion and the particular arrangement position, the dimension information including a tolerance of the particular arrangement position, the acquiring the dimension information including:
• identifying a numerical value associated with the first extension line and the second extension line by analyzing the drawing data;
• and
• acquiring the dimension information based on the numerical value;
• acquiring captured image data obtained by capturing an image of the object on which the constituent part is formed, a captured image indicated by the captured image data including a portion of the object including the constituent part;
• identifying the constituent part in the captured image based on the captured image data;
• identifying the reference portion of the object in the captured image based on the captured image data;
• and
• determining whether an arrangement position of the constituent part in the captured image is the particular arrangement position specified by the dimension information, based on an identification result of the constituent part in the captured image, an identification result of a position of the reference portion in the captured image, and the dimension information.
