On-Vehicle Device Trimming Image Data to Reduce Upload Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional management systems that upload video data from dashboard cameras on vehicles to servers are inefficient in reducing the amount of data transmitted, leading to increased data processing loads and communication costs.
Innovation Solution
An on-vehicle device that uploads trimming information, where a target area is trimmed from captured image information, using a processor to generate and transmit still images instead of full video frames, reducing data volume and processing load by employing video compression and image recognition to identify and upload only relevant frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all video data is uploaded to the server, then complete driving information is available for analysis, but the amount of data transmitted increases significantly
Solution Approach 1:
The patent extracts only the essential driving information elements from complete video data. The on-vehicle device identifies and extracts key parameters such as driving behavior patterns, road conditions, and traffic situations, transmitting only these extracted elements to the server rather than the entire video dataset, thereby reducing transmission volume while preserving analysis capability
Solution Approach 2:
The patent segments video data into discrete, analyzable units or frames, processes each segment to identify relevant information, and transmits only the segmented relevant data points. This segmentation allows the system to break down continuous video streams into manageable information units that can be selectively uploaded based on their analytical value
2Productivity
If video compression and image recognition are employed, then data processing load is reduced, but system complexity increases
Solution Approach 1:
The patent applies video compression and image recognition algorithms as preliminary processing steps on the on-vehicle device before data transmission. By performing these processing actions in advance, the system reduces the volume and complexity of data that needs to be transmitted and processed by the server, improving overall processing efficiency despite the added complexity at the edge device
Solution Approach 2:
The on-vehicle device acts as an intermediary that introduces processing functions between the camera and the server. This intermediary performs compression and recognition tasks, transforming raw video data into processed information units, thereby distributing the processing load and improving system-wide efficiency

AI summary
An on-vehicle device uploads information concerning a vehicle to an external device with a predetermined period, and includes a processor that uploads, to an external device, trimming information where a target area is trimmed from image information that is captured by the vehicle.
