Scanned Image Orientation Correction for Automatic Scoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic scoring systems fail to accurately process scanned test materials when their orientation deviates from the desired direction, leading to poor convenience and inefficiency.
Innovation Solution
An information processing apparatus that includes a scanned image data acquiring section, orientation determining section, scanned image data correcting section, and transmitting section to ensure the scanned image data is properly oriented for automatic scoring, using a code image to determine and correct orientation and facilitate communication with a learning managing apparatus and image forming apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the automatic scoring apparatus directly processes scanned images without orientation verification, then the processing speed is maintained, but the scoring accuracy deteriorates when the test material orientation deviates from the desired direction
Solution Approach 1:
The patent applies preliminary action by verifying the orientation of the scanned test material image before performing automatic scoring. The orientation verification step is executed in advance to detect whether the image is properly oriented, and only appropriately oriented images are transmitted for scoring. This prevents orientation-related errors in the scoring process without requiring complex real-time correction mechanisms during scoring.
2Reliability
If the system verifies and corrects image orientation before scoring, then the scoring reliability is improved, but the processing time increases
Solution Approach 1:
The patent extracts the orientation verification function as a separate, independent step from the main scoring process. By isolating the orientation check as a preliminary filtering operation, the system can quickly identify and exclude improperly oriented images without requiring time-consuming correction or re-scanning operations. This extraction allows the scoring process to focus only on valid, properly oriented images, maintaining overall processing efficiency while improving reliability.
3Ease of operation
If the automatic scoring apparatus processes images without orientation checking, then the ease of operation is maintained, but the convenience deteriorates due to incorrect scoring of misoriented test materials
Solution Approach 1:
The patent applies self-service by implementing automatic orientation verification and validation within the scoring system. The system automatically checks whether scanned test material images are properly oriented before processing, and only transmits appropriately oriented images for scoring. This self-verification mechanism eliminates the need for manual orientation checking by operators, maintaining ease of operation while simultaneously improving convenience by preventing incorrect scoring of misoriented materials through automatic validation.

AI summary
The information processing apparatus includes a scanned image data acquiring section that acquires filled-out teaching material image data indicating a filled-out teaching material image generated by an image forming apparatus reading a filled-out teaching material sheet. The information processing apparatus includes a scanned image data correcting section that corrects the filled-out teaching material image data in such a way that the orientation of the filled-out teaching material image becomes normal when the filled-out teaching material image data is a target of automatic scoring and the orientation of the filled-out teaching material image is not normal, and a scanned image data transmitting section that transmits the filled-out teaching material image data on the filled-out teaching material image having the normal orientation to the teaching material managing apparatus.
