Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies for vehicle surroundings monitoring do not effectively improve the visibility of rotatable three-dimensional images displayed on a display device, particularly at the boundary regions between captured images.
Innovation Solution
A control device and method that generate a three-dimensional image from imaging data of multiple cameras on a moving vehicle, allowing rotation of the image space and adjusting the rotation amount to prevent boundary regions from being in specific, conspicuous regions when the rotation stops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a three-dimensional image is generated by combining captured images from multiple cameras and displayed as a rotatable image, then the user can view the vehicle surroundings from multiple angles, but the visibility deteriorates when boundary regions between captured images are positioned in the specific region (center) when rotation stops
Solution Approach 1:
The system performs preliminary prediction of the boundary region position before the rotation stops. The prediction unit predicts where the boundary region will be located when rotation ceases, and based on this prediction, the rotation amount is adjusted in advance to prevent the boundary from stopping in the specific region, thereby maintaining image quality throughout the rotation animation.
2Manufacturing precision
If the rotation amount is adjusted to avoid boundary regions in the specific region, then image visibility is improved, but the rotation animation may not complete a full 360-degree rotation
Solution Approach 1:
The rotation amount is made dynamic rather than fixed. The determination unit adjusts the rotation amount based on the predicted boundary position, allowing the system to adapt the rotation behavior dynamically. This enables the rotation to stop at optimal positions that avoid boundary regions while still providing comprehensive viewing of the surroundings.
3Ease of operation
If the rotation stops at a position where boundary regions are present in the specific region, then the rotation animation is simple and completes naturally, but user discomfort increases due to reduced visibility
Solution Approach 1:
The system incorporates a feedback mechanism where the prediction unit continuously monitors the boundary region position during rotation. Based on this feedback, the determination unit adjusts the rotation amount to ensure the boundary does not stop in the specific region. This feedback loop eliminates user discomfort while maintaining smooth rotation animation through iterative position optimization.

AI summary
A control device includes circuitry configured to: generate, based on respective pieces of imaging data obtained by a plurality of imaging devices of a moving body, a three-dimensional image indicating a space including both the moving body and surroundings of the moving body; and cause a display device to display the generated three-dimensional image. The circuitry is capable of rotation of the space in the three-dimensional image, and the circuitry changes a rotation amount of the rotation, in a case where it is predicted that a boundary region of the respective pieces of imaging data in the three-dimensional image is present in a specific region when the rotation is stopped.
