Autonomous Vehicle Dispatch Superimposed Image Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulty in identifying the dispatched autonomous driving vehicle approaching their desired pickup position, especially in scenarios with multiple vehicles or complex environments.
Innovation Solution
A vehicle dispatch system that includes a recognition information acquisition unit, storage information acquisition unit, dispatch vehicle position estimation unit, user device position estimation unit, surrounding image generation unit, and superimposed image generation unit, which display the dispatch vehicle's position and user device's position on a superimposed image, allowing users to easily identify the approaching vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the autonomous driving vehicle approaches the pickup position, then the user can receive the vehicle dispatch service, but the user has difficulty specifying which vehicle is the dispatched vehicle
Solution Approach 1:
The system creates a visual copy of the surrounding environment through images captured by cameras mounted on the autonomous driving vehicle. These images are transmitted to the user's terminal device, allowing the user to visually identify the approaching vehicle without needing additional positioning information. The image acts as a visual replica that conveys the vehicle's location and orientation.
Solution Approach 2:
The system introduces an intermediary communication channel between the autonomous driving vehicle and the user's terminal device. Images captured by the vehicle's cameras are transmitted through this intermediary channel, providing the user with visual information about the vehicle's position and surroundings, thereby solving the identification problem.
2Productivity
If multiple autonomous driving vehicles are deployed, then the vehicle dispatch service capacity increases, but the difficulty of identifying the specific dispatched vehicle increases
Solution Approach 1:
Each autonomous driving vehicle transmits visual copies of its surrounding environment through captured images. This allows the user to distinguish between multiple vehicles by viewing the unique visual information each vehicle captures, such as different surrounding landmarks, road conditions, or positions relative to the pickup location.
Solution Approach 2:
The system utilizes visual information from camera images that may include color variations in the surrounding environment, vehicle外观, or visual markers. These visual differences help the user distinguish between multiple autonomous driving vehicles approaching the pickup position.

AI summary
A vehicle dispatch system provides a vehicle dispatch service of an autonomous driving vehicle in response to a vehicle dispatch request from a user. The vehicle dispatch system includes a dispatch vehicle position estimation unit that estimates a dispatch vehicle position based on comparison of a surrounding environment recognition information, which is acquired by a sensor mounted in a dispatch vehicle, with a surrounding environment storage information, which is stored in advance, a user terminal position estimation unit configured to estimate a user terminal position, a surrounding image generation unit configured to generate a surrounding image of the dispatch vehicle based on the surrounding environment recognition information or the surrounding environment storage information, and a display processing unit configured to display a superimposed image having the dispatch vehicle position and the user terminal position superimposed on the surrounding image on a user terminal.
