Rendezvous Assistance via Exterior Image Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In carsharing services, matching between the real world and a map world can be insufficient, making it difficult to achieve a rendezvous between a user and a vehicle, especially in crowded conditions where identifying the correct vehicle or person is challenging.
Innovation Solution
A rendezvous assistance apparatus that includes a first acquisition unit to capture images of the outside, a communication controller to transmit and receive positional information, and a controller to display a first display object indicating the position of the second mobile unit on a display, accompanied by the image or landscape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a rendezvous point is displayed on a map, then the rendezvous location is provided, but matching between the real world and map world is insufficient making it difficult to identify the actual vehicle or person
Solution Approach 1:
The patent transmits a captured image of the outside of the first mobile unit (vehicle) to the second mobile unit (user terminal). This image serves as a visual copy of the actual vehicle exterior, allowing the user to identify their vehicle among multiple vehicles by comparing the transmitted image with the real-world appearance, thereby resolving the identification accuracy problem while maintaining location information display.
2Measurement precision
If face images are transmitted in advance, then identification is assisted, but the face in the image may differ from the actual face making identification still difficult
Solution Approach 1:
Instead of transmitting the user's face image to the driver (which may not match due to lighting, angle, or time differences), the patent inverts the approach by transmitting an image of the vehicle exterior captured by the vehicle's camera to the user. This allows the user to visually confirm their vehicle's appearance and location from the driver's perspective, ensuring accurate identification without the mismatch problems of face images.
3Device complexity
If only a map display is used, then the system is simple, but it takes effort and time to achieve rendezvous in crowded conditions
Solution Approach 1:
The patent introduces an image transmission function as an intermediary between the map display and the actual vehicle identification. The captured exterior image acts as a mediator that bridges the gap between the abstract map location and the concrete visual appearance of the vehicle, enabling rapid identification in crowded environments without significantly increasing system complexity.

AI summary
An object is to provide a technique that allows a first mobile unit to provide an appropriate display that makes it possible to easily identify a second mobile unit in a rendezvous of the first mobile unit and the second mobile unit. A For the rendezvous of the first mobile unit and the second mobile unit, a rendezvous assistance apparatus includes a first controller that performs control to cause a first display of the first mobile unit to display a first display object on the basis of the first receive information received by the first mobile unit, the first display object indicating the position of at least part of the second mobile unit accompanied with the first image or a landscape of the outside of the first mobile unit corresponding to the first image.
