Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video analysis techniques suffer from insufficient accuracy.
Innovation Solution
A video analysis apparatus and method that distributes frames between a first and second video analysis unit, where the first unit detects objects and acquires movement information, and the second unit adjusts the detection results based on the first unit's results and movement information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If video analysis is performed by distributing frames to multiple analysis units, then processing efficiency is improved, but analysis accuracy deteriorates
Solution Approach 1:
The video analysis system is segmented into multiple independent analysis units (first video analysis unit and second video analysis unit) that can process frames in parallel. Each unit has its own detection unit that independently analyzes frames, enabling distributed processing while maintaining individual analysis quality.
Solution Approach 2:
The system implements a feedback mechanism where the second video analysis unit receives detection results and movement information from the first unit, then adjusts its own detection results based on this feedback. This iterative refinement process improves overall analysis accuracy while maintaining the benefits of distributed processing.
2Speed
If multiple video analysis units process frames independently, then processing speed is improved, but detection accuracy deteriorates
Solution Approach 1:
The system merges the detection results from multiple independent analysis units by having the second video analysis unit adjust its detection results based on feedback from the first unit. This combination approach leverages the speed advantage of parallel processing while achieving high accuracy through result integration and refinement.
Solution Approach 2:
Movement information and detection results are transmitted from the first video analysis unit to the second unit, creating a feedback loop that enables continuous refinement of detection accuracy while maintaining fast processing speeds through the distributed architecture.

AI summary
A video analysis apparatus and the like with improved video analysis accuracy are provided.The video analysis apparatus includes a first video analysis unit and a second video analysis unit. The first video analysis unit is configured to distribute frames to the first video analysis unit or the second video analysis unit, detect a target object in frames which are distributed to be analyzed in the first video analysis unit, and acquire information on movement associated with the detected target object, and transmitting the information on the movement and a detection result in the first detection unit to the second video analysis unit. The second video analysis unit is configured to detect a target object in frames from the distribution unit, and adjust the detection result of the first detection unit based on a detection result in the second detection unit and the information on the movement.
