In-Vehicle Image Management System for Rare Data Transmission
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 volumes and frequencies, particularly for rare images.
Innovation Solution
The system includes an in-vehicle device with a camera and sensors that store images and vehicle state data, a portable device for user-controlled image selection and rare image determination, and an image management server that only stores and transmits selected rare images when permitted by the user, reducing unnecessary data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic transmission of all photographed images is implemented, then complete image data is available on the server, but communication volume and frequency become excessive
Solution Approach 1:
The patent extracts only the essential image data (rare images) from the complete set of photographed images for transmission to the server. The portable device determines which images are 'rare' based on comparison with previously stored images, and only these extracted images are transmitted, thereby reducing communication volume while maintaining data reliability for important cases
Solution Approach 2:
Different quality levels of image transmission are applied based on local conditions. Common images are not transmitted (or transmitted with lower priority), while rare images are transmitted with high priority. This local quality differentiation optimizes communication resources by allocating bandwidth based on the actual importance of each image type
2Reliability
If all photographed images are transmitted to the server, then comprehensive image storage is achieved, but communication frequency increases excessively
Solution Approach 1:
The system extracts only rare images from the complete set of photographed images for transmission. The portable device compares each new image with previously stored images and identifies only those that are significantly different or noteworthy, extracting these for transmission while leaving common images local, thereby reducing communication frequency
Solution Approach 2:
The portable device performs preliminary determination of image rarity before transmission. By pre-processing images locally and identifying rare ones in advance, the system avoids unnecessary communication attempts for common images, thereby reducing communication frequency while ensuring complete storage of important rare images on the server

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 portable device. The portable device executes a portable side determination process for determining whether or not the selected image is a rare image by using the selected image and the selected vehicle state, and transmits the selected image determined to be a rare image by the portable side determination process and the selected vehicle state to the image management server only when the transmission is permitted by the user. The image management server stores the selected image and the selected vehicle state transmitted from the portable device in the image storage device.
