Display Control for Camera-Aligned Intersection Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not effectively display intersection images on a remote operator's terminal to enhance visibility and instantaneously grasp the traveling direction of a moving body, leading to confusion and difficulty in determining the positional relation between moving objects and the vehicle.
Innovation Solution
A display control device that arranges intersection images on a display device based on the relation between camera imaging directions and the vehicle's traveling direction, using different modes of display to align the images with the vehicle's perspective, including flipping images horizontally when necessary to match the actual traffic situation.

Engineering Contradiction Analysis
1Reliability
If intersection images are displayed on the remote operator terminal, then the remote operator can confirm safety during remote operation, but the remote operator cannot intuitively grasp the traveling direction and traffic situation without additional processing
Solution Approach 1:
The system performs preliminary actions by acquiring the traveling direction of the moving body in advance, calculating the relative direction between camera imaging direction and traveling direction, and determining the display mode (normal or horizontally flipped) before displaying the image. This preparation ensures that when the intersection image is displayed, the remote operator can immediately and intuitively understand the traffic situation without needing to mentally adjust for directional discrepancies.
2Ease of manufacture
If the camera imaging direction does not match the vehicle traveling direction, then the image can be captured from a fixed camera position, but the remote operator experiences confusion in determining positional relations and traveling direction
Solution Approach 1:
The system changes the display parameter of the image (horizontal flipping) based on the calculated relative direction between the camera imaging direction and the vehicle traveling direction. When the imaging direction and traveling direction differ, the image is horizontally flipped during display. This parameter change ensures that the displayed image accurately reflects the actual traffic situation from the vehicle's perspective, preventing loss of directional information while maintaining fixed camera installation.

AI summary
A display control device is configured to control image display of a display device for remote operation of a moving body. The display device includes one or more screens respectively configured to display one or more intersection images captured by one or more cameras. The one or more cameras are installed at an intersection through which the moving body passes and are configured to each image a traffic situation in an area of the intersection. The display control device includes a processor configured to execute an image process of arranging the one or more intersection images on the one or more screens in different modes depending on a relation between one or more imaging directions of the one or more cameras and a traveling direction of the moving body.
