Server-Based Moving Image Generation for Drive Recorder Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional moving image generation systems require high processing capabilities to analyze expressions and utterances in real time, necessitating a powerful analysis system installed in vehicles, which is impractical and resource-intensive.
Innovation Solution
A moving image generation system that uses a server outside the vehicle to analyze and clip shot data from a drive recorder, setting a clipping range based on mood, gestures, and user specifications to automatically generate a road trip movie, reducing the need for high processing capabilities on the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If real-time analysis of expressions and utterances is performed in the vehicle, then automatic generation of road trip albums is achieved, but high processing capabilities and complex analysis systems are required
Solution Approach 1:
The patent extracts the complex analysis function from the vehicle and places it on a server. The vehicle only performs simple data collection and transmission, while the server handles the complex expression and utterance analysis. This separation resolves the contradiction by maintaining automation while reducing vehicle system complexity.
Solution Approach 2:
The patent introduces a server as an intermediary between the vehicle and the analysis process. The server acts as a mediator that receives data from the vehicle, performs the complex analysis, and returns results. This intermediary approach enables automatic generation without requiring complex systems in the vehicle.
2Productivity
If high processing capabilities are installed in the vehicle, then real-time analysis can be performed, but resource requirements and system costs increase
Solution Approach 1:
The patent extracts the heavy processing requirements from the vehicle and relocates them to a server with adequate resources. This allows the vehicle to maintain productivity in terms of data collection while minimizing the quantity of processing resources needed locally.
Solution Approach 2:
The patent moves the processing dimension from the vehicle to a remote server, effectively changing the spatial dimension of where processing occurs. This allows the vehicle to achieve analysis capability without physically housing the processing resources, thus reducing resource requirements in the vehicle.
3Measurement precision
If complex analysis systems are deployed in vehicles, then accurate expression and utterance analysis is achieved, but ease of operation and system installation become difficult
Solution Approach 1:
The patent extracts the complex analysis system from the vehicle and places it on a server, thereby maintaining analysis accuracy while dramatically improving ease of operation. The vehicle system becomes simple to install and operate, while the server handles the complex analysis tasks.
Data Source
AI summary
The moving image generation server acquires shot data during a load trip by a drive recorder mounted in the vehicle. The moving image generation server analyzes moving image and audio of the shot data. Then, the moving image generation server sets the clipping range based on the analysis result of the moving image and the audio. The moving image generation server automatically generates a moving image obtained by clipping an image of a clipping range from the shot data as a load trip movie.
