Solution Overview
Problem
Existing image data management methods in manufacturing sites face difficulties in efficiently retrieving and reproducing image snap conditions, such as camera position and exposure time, without specialized software, especially in environments without dedicated information processing devices.
Innovation Solution
An image management device that acquires and stores image data and snap conditions as archive data in a text file, allowing easy access and reproduction of image snap conditions without requiring special software, using an image data acquisition unit, image snap condition acquisition unit, and archive data creation unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image data and snap conditions are stored using a database system with dedicated software, then information can be organized and stored, but it becomes difficult to retrieve and reproduce image snap conditions without specialized software and dedicated information processing devices
Solution Approach 1:
The patent creates a simplified copy of the database structure by storing image snap conditions in a text file with a specific format that can be read by any text editor. This copy contains all necessary information (camera position, exposure time, reduction ratio, snap range) in a human-readable and easily accessible format, eliminating the need for specialized software while maintaining data integrity and organization.
Solution Approach 2:
The text file acts as an intermediary between the complex database system and the user. It translates structured database information into a simple, universal format that can be accessed without dedicated software, serving as a bridge that maintains data reliability while improving accessibility and ease of operation.
2Loss of information
If multiple types of information (camera position, exposure time, reduction ratio, snap range) are stored for every image data, then complete image snap conditions can be reproduced, but the complexity of collecting and managing this information increases
Solution Approach 1:
The patent segments the image management information into distinct, clearly labeled fields within the text file (camera position, exposure time, reduction ratio, snap range). Each parameter is separated and identified with a specific tag, making it easy to locate and extract individual pieces of information without having to process the entire dataset, thus reducing management complexity while maintaining completeness.
Solution Approach 2:
The patent changes the format parameter from a complex database structure to a simple text file format. This parameter change simplifies the information management system while preserving all necessary data elements, allowing complete image snap conditions to be stored and retrieved without increasing device or system complexity.
3Adaptability or versatility
If image data and snap conditions are stored in separate locations, then data can be managed independently, but it becomes difficult to collect all necessary information to reproduce a single vision program execution state
Solution Approach 1:
The patent merges image data and snap condition information into a single integrated storage unit (text file) that contains both the image file path and all associated snap conditions. This combination eliminates the need to separately collect and correlate information from multiple locations, reducing the time required to gather complete image snap conditions while maintaining the flexibility to manage data independently through the structured format.
Data Source
AI summary
An image management device includes: an image data acquisition unit that acquires image data snapped by a visual sensor; an image snap condition acquisition unit that acquires an image snap condition applied when the image data is snapped, from a manufacturing machine and the visual sensor; an archive data creation unit that creates archive data based on the image data and the image snap condition; and an archive data storage unit that stores the archive data. The archive data creation unit creates archive data after recording the image snap condition in a file. The image management device can easily reuse image data that is snapped by the visual sensor attached to the manufacturing machine and an image snap condition of the image data.
