[0029] The first embodiment will be described. figure 1 It is a schematic diagram of an image processing device 10 as an example according to the first embodiment.

[0030] The image processing device 10 is used for inventory management, location management, and the like of a plurality of articles (for example, cardboard boxes) placed on a plurality of shelves in a warehouse or a store. The image processing device 10 has a computer 11 , a moving body 12 , a first imaging unit 13 , and a second imaging unit 14 . The image processing device 10 does not necessarily have to have all these elements. For example, the image processing device 10 may be a device including at least the computer 11 .

[0031] The computer 11 is a device that recognizes characters from images through OCR processing as described later. The computer 11 is, for example, a PC (Personal Computer: personal computer). In addition, a character is a concept including identification codes such as numbers, signs...

[0068] A second embodiment will be described. Here, points different from those of the first embodiment will be described, and descriptions of the same points will be omitted. Figure 7 It is a schematic diagram of an image processing device 10 as an example according to the second embodiment. The image processing device 10 according to the second embodiment corresponds to the image processing device 10 according to the first embodiment except the second imaging unit 14 and the second interface 116 . That is, the image processing device 10 according to the second embodiment has only one imaging unit for imaging an object.

[0069] The processing of character recognition based on the image processing device 10 is image 3 Act101, Act105 and Act106 differ from the first embodiment.

[0070] In Act 101 , the processing unit 111 collects the data of the first image and the second image obtained by the first imaging unit 13 through the first interface 115 . The first image and ...

Abstract

According to one embodiment, an image processing apparatus includes a calculation unit and a recognition unit. The calculation unit is configured to calculate a first similarity degree group which is composed of similarity degrees between respective characters constituting a first character string appearing on a first image and respective candidate characters in a candidate character group, and to calculate a second similarity degree group which is composed of similarity degrees between respective characters constituting a second character string appearing on a second image and the respective candidate characters in the candidate character group.

Description

[0001] This application claims priority to the U.S. application with the filing date of April 8, 2015 and the application number US14 / 681,933, and cites the content of the above application. technical field [0002] The invention relates to an image processing device and an image processing method. Background technique [0003] Generally, OCR (Optical Character Recognition: Optical Character Recognition) processing is performed on a character image obtained by scanning characters written (recorded) on paper. In recent years, application software that corrects character images captured by cameras and performs OCR processing on the corrected character images has appeared (launched) as the resolution of cameras has increased. The OCR process not only analyzes the character image to determine the corresponding character, but also can determine the final character while analyzing the meaning of the character string. Usually, the OCR processing of a character image captured by a ...
