Anti-skid Tool Detection via Image Recognition for Vehicle Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for determining when to attach anti-skid tools, such as chains, on vehicles are inadequate as they rely solely on weather data and snow accumulation rankings, neglecting other critical factors like road inclination, making it difficult to accurately assess where these tools are needed.
Innovation Solution
An information provision and driving assistance system that uses image recognition and position measurement technologies to detect the installation of anti-skid tools on vehicles and communicate this information to other vehicles, allowing for accurate determination of where these tools should be installed based on real-time data and vehicle positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If snowy road rank is used to determine chain attachment necessity, then the determination can be made based on available weather data, but the accuracy of determining where chains are needed deteriorates due to ignoring other factors like road inclination
Solution Approach 1:
The patent introduces an image recognition system as an intermediary to detect anti-skid tool installation on vehicles. This intermediary captures visual evidence from the environment and translates it into actionable data about actual chain attachment locations, complementing the weather data-based snowy road rank system and improving overall determination accuracy
Solution Approach 2:
The patent replaces the purely weather-data-based mechanical determination system with an enhanced system that incorporates image recognition and visual detection. This substitution allows the system to observe actual chain attachment behavior and use it to improve the accuracy of determining where chains are needed, beyond what weather data alone can provide
2Measurement precision
If image recognition is used to detect anti-skid tool installation, then the accuracy of identifying where tools are needed is improved, but the device complexity increases due to additional imaging and processing requirements
Solution Approach 1:
The patent makes the image recognition system serve multiple functions: detecting anti-skid tool installation, identifying vehicle positions, and providing visual data for map generation. This multi-functionality justifies the added complexity by having the same system perform several critical tasks that improve overall system accuracy
Solution Approach 2:
The image recognition system detects anti-skid tool installation on vehicles autonomously without requiring manual input or intervention. The system self-services by automatically capturing images, processing them to detect chain attachment, and using this information to improve determination accuracy, thereby managing its own complexity through automation

Data Source
AI summary
An information provision device includes a controller configured to detect installation of an anti-skid tool onto a vehicle from an image including at least a part of the vehicle and at least a part of the vicinity of the vehicle and a communication unit configured to provide position information of the vehicle at the time of the installation of the anti-skid tool detected by the controller. A driving assistance device includes a communication unit configured to acquire position information of a vehicle at the time of installation of an anti-skid tool when the installation of the anti-skid tool onto the vehicle is detected from an image including at least a part of the vehicle and at least a part of a vicinity of the vehicle, and a controller configured to present information acquired by the communication unit to the driver of another vehicle different from the vehicle.
