Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Transmitting all images captured while a vehicle is traveling results in a large communication load and storage requirements, indicating a need for improved image transmission technology.

Innovation Solution

An information processing method and system where a vehicle captures and stores images, and transmits them only when a change in speed greater than or equal to a threshold occurs within a predetermined section, allowing for targeted image transmission to an information processing apparatus for analysis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If all images captured while a vehicle is traveling are transmitted, then complete image data is available for analysis, but communication load and storage requirements increase significantly

Engineering Contradiction:

Improveimage data completenessVSAvoidcommunication load

Core Design Contradiction:

Loss of informationVSLoss of energy

Solution Approach 1:

The patent extracts and transmits only the necessary image data (images containing road signs) rather than all captured images. The in-vehicle apparatus selectively identifies and transmits only those images that meet specific criteria (containing road signs within a predetermined period), thereby reducing communication load while preserving essential information for analysis.

Inventive Principle:

Principle #2Taking out (Extraction)

2Loss of information

If all images captured while a vehicle is traveling are transmitted, then complete image data is available for analysis, but storage capacity requirements at the data center increase

Engineering Contradiction:

Improveimage data completenessVSAvoidstorage capacity

Core Design Contradiction:

Loss of informationVSQuantity of substance

Solution Approach 1:

The system extracts and transmits only relevant image data containing road signs rather than all captured images. By filtering images based on the presence of road signs and transmitting only those that meet the criteria, the patent significantly reduces the volume of data requiring storage at the data center while maintaining analytical completeness.

Inventive Principle:

Principle #2Taking out (Extraction)

3Loss of energy

If images are transmitted only when speed change occurs, then communication load and storage needs are reduced, but image transmission efficiency may be compromised

Engineering Contradiction:

Improvecommunication loadVSAvoidimage transmission efficiency

Core Design Contradiction:

Loss of energyVSProductivity

Solution Approach 1:

The in-vehicle apparatus performs preliminary analysis of captured images to identify those containing road signs before transmission. By pre-processing images locally and selecting only relevant ones for transmission based on speed change events, the system ensures that transmitted images are of high value while maintaining communication efficiency.

Inventive Principle:

Principle #10Preliminary action

AI summary

An information processing method for a vehicle includes capturing and storing images of an area in front of the vehicle, acquiring information on the speed of the vehicle, and transmitting an image to an information processing apparatus when a judgment is made that a change in speed equal to or greater than a threshold occurs while the vehicle is traveling in a predetermined section, the image being captured during a predetermined period that includes the time when the judgment is made.
