Vehicle Image Data Correlation via WiFi Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle image acquisition systems cannot correlate multiple pieces of image information of a vehicle, providing only one unclear piece of information to users, making it difficult to judge vehicle violations or identify detailed vehicle information.
Innovation Solution
A method and system that utilize a WiFi detector to obtain unique identification information of WiFi terminals, combining this information with vehicle image data to enable the data server to correlate and provide multiple pieces of image information to users, allowing clearer data selection and violation judgment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple image acquisition devices capture vehicle images, then the quantity of image information increases, but the data server cannot correlate these images and can only provide one unclear piece to the user
Solution Approach 1:
The patent introduces WiFi detection information as an intermediary element to correlate multiple vehicle images. The image acquisition device obtains WiFi detection information (MAC addresses) from terminals in the vehicle, and uses this information as a mediator to link multiple images captured by different devices. The data server then uses this WiFi information to correlate images that would otherwise be impossible to connect, enabling the user to receive multiple correlated clear images instead of one unclear image.
2Device complexity
If only one piece of image information is provided to the user, then the system complexity is reduced, but the user cannot clearly judge vehicle violations or identify detailed vehicle information
Solution Approach 1:
The patent segments the image provision process into two parts: the data server provides multiple segmented image pieces to the user, and the user's terminal device performs the final assembly and selection. This segmentation allows the server to send multiple clear images without overwhelming complexity, while the user can select the clearest image or composite them to judge violations and identify vehicle details.
3Ease of operation
If the data server stores and processes multiple vehicle image pieces, then the user can select clearer data, but the requirement for image correlation capability increases system complexity
Solution Approach 1:
The patent applies preliminary action by having the image acquisition device obtain and attach WiFi detection information to each image before sending it to the data server. This preliminary correlation work is done at the edge device, so when the user requests images, the server can quickly retrieve and provide multiple correlated images without needing complex real-time correlation processing capabilities.

AI summary
Embodiments of the present application disclose a method, device, system and server for acquiring and providing vehicle image data. The method for providing vehicle image data includes: receiving a query request message for vehicle image data which carries unique identification information (S201, S405); obtaining each piece of vehicle image data corresponding to the unique identification information based on the unique identification information and pieces of vehicle image data containing unique identification information stored in an image database, and providing each piece of vehicle image data corresponding to the unique identification information to a user (S202, S406); vehicle image data stored in the image database are sent by an image acquisition device after acquiring the vehicle image data, the vehicle image data acquired by the image acquisition device include image information of a vehicle, and unique identification information of at least one WiFi terminal obtained using a preset WiFi detector when acquiring the image information of the vehicle. In embodiments of the present application, multiple pieces of image information of a vehicle can be correlated and provided to a user together.
