Summary: | To use self-learning for enhancing efficiency in acquiring necessary information in a ledger sheet through automatic character recognition.SOLUTION: A ledger sheet information recognition device comprises: an acquisition section which acquires a ledger sheet image from a ledger sheet; an extraction section which extracts positional information on a portion subjected to character recognition in the ledger sheet image; a storage section which stores model information with the positional information defined for respective types of ledger sheets; a character recognition section which performs either a character recognition process of the portion subjected to the character recognition corresponding to the positional information defined in the model information when the model information with the positional information corresponding to the same extracted by the extraction section defined is stored in the storage section or the character recognition process of the portion subjected to the character recognition designated through operation input in the ledger sheet image when the model information is not stored in the storage section; and a model creation section which, when the character recognition process of the designated portion subjected to the character recognition is completed, creates the model information for the ledger sheet corresponding to the ledger sheet image using the positional information in the ledger sheet image of the designated portion subjected to the character recognition and allows the storage section to store the created model information.SELECTED DRAWING: Figure 1
【課題】 帳票のから必要な情報を自動的に文字認識する効率を高めるように自己学習する。【解決手段】 実施形態によれば、帳票から帳票イメージを取得する取得部と、帳票イメージにおいて文字認識対象部分の位置情報を抽出する抽出部と、位置情報を、帳票種類毎に定義したモデル情報を保存する保存部と、抽出部によって抽出された位置情報に一致する位置情報が定義されたモデル情報が保存部に保存されている場合、このモデル情報に定義されている位置情報に対応する文字認識対象部分の文字認識処理を行い、保存されていない場合、帳票イメージにおいて、操作入力によって指定された文字認識対象部分の文字認識処理を行う文字認識部と、指定された文字認識対象部分の文字認識処理がなされた場合、指定された文字認識対象部分の帳票イメージにおける位置情報を用いて、帳票イメージに対応する帳票のためのモデル情報を作成し、作成したモデル情報を、保存部に保存させるモデル作成部とを備える。【選択図】図1 |
