In-Vehicle Image Management System for Reducing Communication Volume
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information management systems for vehicles transmit excessive amounts of image data regardless of necessity, leading to high communication volume and frequency, particularly for rare images.
Innovation Solution
An information management system where an in-vehicle device transfers selected images and vehicle state data to a portable device only when user-permitted, which then transmits these data to an image management server for determination and storage as rare images, reducing unnecessary communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic transmission of images meeting predetermined conditions is implemented, then image management is simplified, but communication volume increases excessively
Solution Approach 1:
The patent extracts the image determination function from the edge device and relocates it to the image management server. Only images that have been pre-selected by the user at the edge device are transmitted to the server for final determination as rare images. This extraction reduces the volume of data processed and transmitted while maintaining the simplicity of automatic management for common images.
Solution Approach 2:
The patent implements preliminary action by having the edge device perform image selection and preliminary determination before transmission to the server. The user selects images at the edge device, and the system pre-filters them before they reach the image management server. This preliminary processing reduces the communication burden while maintaining effective rare image identification.
2Reliability
If all photographed images are transmitted to the server, then rare images are not missed, but communication frequency and volume become excessive
Solution Approach 1:
The patent segments the image processing workflow into two distinct stages: edge device processing (user selection and preliminary filtering) and server processing (final rare image determination). This segmentation allows the system to handle only necessary images at the server level, reducing communication frequency while maintaining reliable rare image detection through the collaborative effort of both stages.
Solution Approach 2:
The patent introduces the edge device as an intermediary between the camera and the image management server. The edge device acts as a mediator that performs preliminary selection and filtering, transmitting only selected images to the server. This intermediary role reduces communication volume while ensuring that rare images are not missed through the user's selection process.
3Quantity of substance
If user selection of images is required, then communication volume is reduced, but operation complexity increases
Solution Approach 1:
The patent implements self-service by enabling the user to directly select and determine which images to transmit without requiring complex automated processing. The user's own judgment and selection process is leveraged to filter images, reducing communication volume while keeping the operation simple and intuitive. The system trusts and utilizes the user's expertise in identifying important images.
Data Source
AI summary
The in-vehicle device transfers the selected image selected by the user from the photographed images stored in the storage device and the selected vehicle state, which is the vehicle state when the selected image is captured, to the form terminal. The portable device transmits the selected image and the selected vehicle state to the image management server only when the transmission is permitted by the user. The image management server determines whether or not the selected image is a rare image using the selected image and the selected vehicle state, and stores the selected image in the image storage device when the selected image is determined to be a rare image.
