Image Recognition Apparatus Using Frame-Based Reference Data Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image recognition techniques are prone to erroneous object recognition due to faults in recognition reference data, which increases processing load and is not realistically monitorable in real-time.
Innovation Solution
An image recognition apparatus that alternately switches between multiple sets of recognition reference data on a frame basis, using a storage unit and recognition determining unit to ensure that recognition results meet a predetermined condition before outputting effective results, thereby preventing erroneous recognition and allowing for fault tolerance without increasing processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If recognition reference data is monitored in real-time to detect faults, then recognition reliability is improved, but processing load increases significantly
Solution Approach 1:
The patent applies preliminary action by pre-storing multiple identical copies of recognition reference data in the storage unit before actual recognition operations begin. This allows the system to quickly switch between copies when faults are detected without requiring real-time monitoring or complex processing to generate backup data, thus improving reliability while avoiding increased processing load.
Solution Approach 2:
The patent uses copying by creating multiple identical copies of the recognition reference data and storing them in the storage unit. When a fault is detected in one copy, the system can immediately switch to another copy without requiring complex fault detection algorithms or increasing processing complexity, thereby maintaining high reliability with minimal additional processing load.
2Reliability
If multiple sets of recognition reference data are stored and switched between, then fault tolerance is improved, but storage requirements increase
Solution Approach 1:
The patent implements copying by storing multiple identical copies of recognition reference data in the storage unit. This approach provides fault tolerance through redundancy while keeping storage requirements manageable by using exact copies rather than varied datasets, allowing the system to switch between copies when faults occur without requiring excessive storage capacity.

AI summary
An image recognition apparatus includes a storage unit which stores a plurality of pieces of identical recognition reference data which are used as references for recognizing a specific object from an image, an image recognition unit which recognizes the specific object by alternately making a switch between the plurality of pieces of recognition reference data, on a frame basis, stored in the storage unit, for consecutive frames of the image acquired by an image acquisition unit, and a recognition determining unit which, on condition that recognition results obtained by the image recognition unit by using the plurality of pieces of recognition reference data meet a predetermined matching condition, outputs the recognition results as effective recognition results.
