Identification Device Using Transmitted Operation Patterns
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional identification systems face a high risk of misidentification when attempting to identify moving bodies, such as vehicles, due to the difficulty in accurately detecting and recognizing operation patterns from images, especially in dynamic environments.
Innovation Solution
An identification device that generates and transmits a specific operation pattern to a moving body, detects the executed operation pattern from images, and compares it with the original to ensure matching patterns, thereby accurately identifying the moving body and reducing misidentification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If operation patterns are detected from images to identify moving bodies, then identification capability is provided, but misidentification risk increases due to difficulty in accurately detecting and recognizing operation patterns from images in dynamic environments
Solution Approach 1:
The identification device transmits a predetermined operation pattern to the moving body before detection. This preliminary action ensures that the moving body performs a specific, pre-defined operation sequence, making it easier to accurately detect and recognize the operation pattern from images, thereby reducing misidentification risk while maintaining identification capability
Solution Approach 2:
The system detects the operation pattern executed by the moving body and compares it with the transmitted predetermined operation pattern. This feedback mechanism allows verification of whether the detected pattern matches the expected pattern, enabling accurate identification while minimizing misidentification by confirming pattern consistency
2Ease of operation
If image-based detection is used to identify moving bodies, then non-contact identification is achieved, but detection accuracy deteriorates in complex scenarios like bad weather
Solution Approach 1:
By transmitting a predetermined operation pattern before detection, the system ensures that the moving body performs a specific sequence of operations. This makes the operation pattern more distinct and recognizable even in complex scenarios like bad weather, maintaining detection accuracy while preserving non-contact identification capability
Solution Approach 2:
The system changes the operational parameters of the moving body by having it execute a specific predetermined operation pattern rather than random operations. This parameter change makes the operation pattern more distinguishable and easier to detect accurately from images, even when environmental conditions like weather are complex

AI summary
An identification device includes: an operation generator that generates a first operation pattern to be executed by a first moving body among moving bodies, and transmits the first operation pattern to the first moving body; an operation detector that detects second operation patterns executed by the moving bodies, using at least one image obtained by at least one image obtaining device; and a target identifier that obtains, from the first moving body, a time at which the first moving body executed the first operation pattern, and compares the first operation pattern with a second operation pattern detected at the time from second operation patterns to determine whether these patterns match each other. When determining that they match each other, the target identifier identifies, as the first moving body, a moving body that is included in at least one image and executed the second operation pattern detected at the time.
