Accident Video Collection Using Nearby Vehicle Compression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods and apparatuses for collecting accident vehicle videos suffer from slow data transmission speeds due to a lack of separate processing when transmitting video recordings to other vehicles or servers, which also affects the speed of providing traffic information.
Innovation Solution
A method and apparatus that identify nearby vehicles based on position information, obtain a reduced data size video from these vehicles, and transmit it to a video collecting device, using V2V communication and data processing to enhance transmission speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If video data is transmitted without separate processing, then the transmission process is simple, but the data transmission speed is slow
Solution Approach 1:
The patent applies preliminary action by performing video processing (encoding, compression, or selection of key frames) at the source vehicle before transmission. This preprocessing reduces the data size that needs to be transmitted, thereby increasing transmission speed without adding complexity to the transmission system itself.
Solution Approach 2:
The patent segments video data into manageable units such as key frames, intermediate frames, or divided video segments. This segmentation allows for more efficient processing and transmission, as smaller data units can be handled more quickly by communication systems while still conveying essential accident scene information.
2Loss of energy
If full-resolution video is transmitted, then the video quality is high, but the network bandwidth is consumed
Solution Approach 1:
The patent applies local quality by transmitting high-resolution data only for critical regions of the video (such as the accident scene area) while using lower resolution for other areas. This selective quality approach maintains sufficient video quality for accident analysis while significantly reducing overall bandwidth consumption.
Solution Approach 2:
The patent transmits only the necessary portion of video data required for accident analysis rather than complete full-resolution videos. This partial action approach provides sufficient information for determining liability while conserving network bandwidth resources.

AI summary
A method and apparatus for collecting a video of a vehicle in an accident includes obtaining position information of the accident vehicle at a time when an accident occurs, identifying, based on the position information, a nearby vehicle located within a predetermined distance from the accident vehicle, obtaining, from the nearby vehicle, a video having a reduced data size of the video capture of the accident vehicle, and outputting the video having the reduced data size.
