Abstract
An attachment tool includes an image capturing unit configured to capture an image of a random pattern provided on a comparison region of a part; and an identification result-outputting unit configured to output a part identification result obtained by comparing an image characteristic of the captured image of the random pattern with a previously stored image characteristic of a random pattern of a part.
Claims17
An attachment tool comprising:
- a camera capturing an image of a random pattern provided on a comparison region of a part;
- a covering part having a shape covering an area where the random pattern for the part is provided comprising a partially-dark-colored surface corresponding to a range in a predetermined angle from a normal direction and facing the area where the random pattern is provided, and a light dispersing-and-emitting surface corresponding to a range in an angle other than the predetermined angle;
- a memory storing instructions;
- and
- a processor executing the instructions to perform:
- obtaining a result of comparing an image characteristic of the captured image of the random pattern of the part with a previously stored image characteristic of the random pattern of the part, and
- outputting the result of the comparing indicating matching or mismatch.

A work management method comprising:
- capturing an image of a random pattern provided on a comparison region of a part by a camera comprised in an attachment tool, wherein, a covering part formed to cover a region on which the random pattern of the part is provided comprises a partially-dark-colored surface corresponding to a range in a predetermined angle from a normal direction and facing the area where the random pattern is provided, and a light dispersing-and-emitting surface corresponding to a range in an angle other than the predetermined angle;
- and
- obtaining a result of comparing an image characteristic of the captured image of the random pattern of the part with a previously stored image characteristic of the random pattern of the part, and
- outputting the result of the comparing indicating matching or mismatch, by the attachment tool.

A comparison device comprising:
- a memory storing instructions;
- and
- a processor executing the instructions to perform:
- comparing an image characteristic extracted from an image of a random pattern that is provided on a comparison region of a part and captured by a camera comprised in an attachment tool with a previously stored image characteristic of the random pattern of the part, the image characteristic being stored in storage device, wherein, a covering part formed to cover a region on which the random pattern of the part is provided comprises a partially-dark-colored surface corresponding to a range in a predetermined angle from a normal direction and facing the area where the random pattern is provided, and a light dispersing-and-emitting surface corresponding to a range in an angle other than the predetermined angle;
- and
- outputting the result of the comparing.
