Drive Recorder Video Retrieval for Accident Vehicle Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video retrieval systems from drive recorders are ineffective in utilizing captured video data if the recorder's vehicle is not at the scene of an accident, limiting the ability to identify involved vehicles.
Innovation Solution
An imaging device with an imaging unit, video recording unit, event information receiving unit, and video retrieving unit that captures and analyzes video data within specific time and location parameters to identify relevant vehicles involved in accidents, even if the recording vehicle is not present, using discriminators for vehicle type recognition and scoring search results for prioritization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video data is transmitted only when the recorder's vehicle is at the accident scene, then direct evidence is obtained, but video data from other vehicles in the vicinity cannot be utilized
Solution Approach 1:
The system enables video recording units to serve multiple functions: not only recording their own vehicle's video data but also receiving and storing video data from other vehicles in the vicinity. This multi-functionality allows the system to utilize video evidence from multiple sources, expanding the scope of available evidence while maintaining reliability through systematic management of diverse video data sources
2Measurement precision
If manual collection and transmission of video data is required, then data accuracy is maintained, but effort and time consumption increase
Solution Approach 1:
The system performs preliminary actions by automatically collecting, managing, and pre-processing video data from multiple recording units before it is needed for accident investigation. The video management server continuously receives and organizes video data in advance, so when an accident occurs, the relevant video data is already prepared and can be quickly retrieved without manual collection, thus reducing time loss while maintaining data accuracy through systematic management
Solution Approach 2:
The system enables self-service by allowing recording units to automatically transmit their video data to the video management server without requiring manual intervention. The server then automatically manages, stores, and makes the data available for retrieval, eliminating the need for manual data collection and transmission while maintaining data integrity through automated processes
