Ledger Sheet Recognition Merging Multiple Pages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ledger sheet recognition techniques face challenges in managing multiple-page ledger sheets, as they often recognize image data from multiple pages as separate sheets, leading to inefficiencies in time and effort for data management.
Innovation Solution
An information processing system and method that extracts ledger sheet management information from recognized data, allowing for the combination of multiple-page ledger sheet images based on predefined conditions, displaying a preview screen with combined images to facilitate efficient management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ledger sheet recognition is performed on multiple-page ledger sheets using existing techniques, then character strings can be read from each page, but the image data from multiple pages is recognized as representing different ledger sheets, increasing time and effort for management
Solution Approach 1:
The patent merges multiple ledger sheet images into a single recognized entity by extracting management information (such as invoice number, date, or other identifying fields) from each page and comparing them. When the management information indicates they belong to the same ledger sheet, the system combines them into one unified recognition result, allowing multiple pages to be treated as a single ledger sheet rather than separate entities, thereby reducing management time and effort
2Measurement precision
If ledger sheet recognition is performed on multiple-page ledger sheets using existing techniques, then character strings can be read from each page, but the time and effort for managing the ledger sheet increases
Solution Approach 1:
The patent merges multiple ledger sheet images into a single recognized entity by extracting management information (such as invoice number, date, or other identifying fields) from each page and comparing them. When the management information indicates they belong to the same ledger sheet, the system combines them into one unified recognition result, allowing multiple pages to be treated as a single ledger sheet rather than separate entities, thereby reducing management time and effort
3Ease of manufacture
If multiple-page ledger sheet images are processed separately, then each page can be recognized independently, but the system complexity increases for handling multiple pages as one entity
Solution Approach 1:
The patent segments the ledger sheet recognition process into two distinct stages: first, independent recognition of each page to extract character strings and management information; second, a combination stage that compares management information across pages to determine if they belong to the same ledger sheet. This segmentation allows the system to maintain processing simplicity for individual pages while introducing controlled complexity only when needed for combining multiple pages, making the overall system manageable
Data Source
AI summary
An information processing system includes at least one information processing apparatus. The information processing system includes circuitry that outputs a list of ledger sheet management information items to a terminal apparatus. Each of the ledger sheet management information items is extracted from a ledger sheet recognition result of ledger sheet recognition executed on ledger sheet image data of a ledger sheet. Based on a combination of ledger sheet management information items included in the list of ledger sheet management information items and identified as meeting a certain condition, the circuitry causes the terminal apparatus to display a preview screen including respective preview images of a plurality of ledger sheet images corresponding to the ledger sheet management information items included in the combination of ledger sheet management information items.
