必要としない。The laser projector 2 irradiates the surface of the article to be managed 1 with laser light. FIG. 1 shows an embodiment in which parallel light of a laser beam of 760 nm and 5 mW is applied to the article to be managed 1 separated by 30 cm. The irradiation beam diameter of the laser beam irradiated on the surface of the article to be managed 1 is a circular shape of about 5 mm. did. in this case,
When the article to be managed 1 is smaller than the irradiation beam diameter of the laser beam, the entire opposite surface of the article can be irradiated with the laser beam. Therefore, in this case, the irradiation position of the article is specified only by irradiating the entire opposing surface of the article with the laser light, and no other special procedure for specifying the irradiation position of the article is required.

の集合を意味している。The speckle pattern 8 picked up by the CCD camera 3 is removed by the image processing device 4 by removing a relatively small grain pattern 8a among the irregular grain patterns in order to obtain a binarized image. Processing for processing the value image is performed. FIG. 2 shows the speckle pattern 8 in this state. A relatively small grain pattern 8a shown by a broken line is a pattern to be removed from an image, and a relatively large grain pattern 8b shown by a solid line is a speckle pattern. These are the individual grain patterns constituting the pattern. Therefore, in the illustrated embodiment, the speckle pattern stored in the storage device is strictly a granular pattern 8b indicated by a solid line.
