Abstract

Official abstract text for this publication.

A character recognition device includes a recognizer that recognizes at least one character string from an image including a trailer captured by an imaging device, an attribute determinator that determines an attribute of the character string recognized by the recognition unit, and a trailer ID estimator that estimate whether the character string is a trailer ID based on the attribute of the character string determined by the attribute determinator.

First claim

Opening claim text (preview).

1 . A character recognition device comprising: a recognizer that recognizes at least one character string from an image including a trailer captured by an imaging device; and an ID estimator that estimates a possibility that the character string is a trailer ID is higher when a writing manner of the character string is vertical writing than when writing manner of the character string is horizontal writing. 2 . The character recognition device according to claim 1 , wherein The ID estimator estimates that the character string is the trailer ID when the writing manner of the character string is the vertical writing and a content indicated by the character string is not a container ID according to a predetermined specification. 3 . The character recognition device according to claim 2 , wherein the container ID is a container ID regulated by ISO6346. 4 . The character recognition device according to claim 2 , wherein the ID estimator estimates that the character string is not the trailer ID when the character string is the container ID according to the predetermined specification. 5 . (canceled) 6 . The character recognition device according to claim 4 , wherein the ID estimator estimates that the character string is the trailer ID when the writing manner of the character string is the vertical writing and the character string is written at a corner of the trailer. 7 - 11 . (canceled) 12 . The character recognition device according to claim 6 , wherein the ID estimator estimates that the possibility that the character string is the trailer ID is higher when the character string includes both of a character and a number than when the character string includes only the character or only the number. 13 . The character recognition device according to claim 1 , wherein the ID estimator estimates that the possibility that the character string is the trailer ID is higher when a number of characters in the character string is within a predetermined range than when the number of characters in the character string is out of the predetermined range. 14 . (canceled) 15 . The character recognition device according to claim 1 , wherein the ID estimator outputs a determination result to a display device. 16 . A character recognition method comprising: recognizing at least one character string from an image including a trailer captured by an imaging device; and estimating a possibility that the character string is a trailer ID is higher when a writing manner of the character string is vertical writing than when the writing manner of the character string is horizontal writing.
