Article specifying information for specifying articles collected in an article collection site is detected from an image captured by an imaging unit (). When the article specifying information is detected, a position of the article in the article collection site are determined from the position of the article specifying information in the captured image, and article information in which the detected article specifying information is correlated with position information indicating the determined position of the articles is stored. The position information of a pickup target article corresponding to the article specifying information of the pickup target article is acquired with reference to the article information. A laser beam output unit () presents the position of the pickup target article to a pickup operator so as to recognize the presented position by irradiating the position of the pickup target article with a laser beam on the basis of the acquired position information.

Pickup system and pickup method

A two-dimensional code reader and program generate edge images based on obtained images, extract candidate regions within these edge images, determine whether or not the extracted candidate regions are valid, determine whether or not characteristic patterns are included in each corresponding region in the original image, and then detects two-dimensional code regions within original images. The two-dimensional code reader and program repeatedly implement generation of edge images based on conversion conditions that correspond to the applicable order among a plurality of conversion condition types in a pre-set order, detection of candidate regions among the generated edge images, determination of whether or not the extracted candidate regions are valid, determination of whether or not characteristic patterns are included in the corresponding regions in the original images that correspond to valid candidate regions, and detection of two-dimensional code regions.

Two-dimensional code reader and program

Disclosed is a technology that specifies each of a plurality of two-dimensional codes in an image and reduces the processing time for judging color in each cell region in each specified two-dimensional code. Based on edge images generated from obtained images, candidate regions among these edge images are extracted, a judgment is made about whether or not a characteristic pattern is included in each of the corresponding regions in the original images that correspond to these extracted candidate regions, and then the two-dimensional code regions are detected from among the original images. The color is judged both for each pixel group that comprises each row of that region and for each pixel cell, in pixel array order. If it is determined that a certain number or more pixels in each row that corresponds to each cell region are included in the color judgment region, color judgment is omitted for the remaining pixels in that row.
