Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image generating devices for water-surface movable bodies cannot capture a 360-degree view around the device, limiting the ability to image directions different from the imaging device's direction, and lack indication for unavailable capture ranges.
Innovation Solution
An image generating device with a captured image inputting module, position acquiring module, posture acquiring module, additional display information acquiring module, and synthesized image generating module that creates a synthesized image by superimposing virtual reality graphics on the captured image based on positional and posture information, allowing indication of areas beyond the captured image range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single camera is used to image the situation around the water-surface movable body, then the device complexity is reduced, but the coverage area is limited and cannot capture 360 degrees
Solution Approach 1:
The patent creates a virtual copy of the captured image in three-dimensional space, allowing the limited camera view to be represented and extended virtually. The captured image is projected onto a three-dimensional virtual space, creating a virtual model that can be viewed from multiple angles without adding physical cameras.
Solution Approach 2:
The patent transitions from two-dimensional image display to three-dimensional virtual space representation. By projecting the captured image onto a three-dimensional virtual space and allowing rotation around the water-surface movable body, the system provides omnidirectional viewing capability without requiring multiple physical cameras.
2Loss of information
If the captured image is displayed in its original form, then the ease of operation is maintained, but the loss of information occurs for directions not captured by the camera
Solution Approach 1:
The system creates a virtual copy of the physical environment by projecting the captured image onto a three-dimensional virtual space. This virtual model preserves all spatial information and can be rotated to display any direction, eliminating information loss without requiring additional physical sensors.
Solution Approach 2:
The patent introduces a three-dimensional virtual space as an intermediary between the captured image and the display. This virtual space acts as a mediator that preserves all spatial information from the limited camera view and makes it accessible from any viewing angle through virtual rotation.
3Area of stationary object
If multiple cameras are installed to achieve 360-degree coverage, then the coverage area is improved, but the device complexity and cost increase
Solution Approach 1:
Instead of using multiple physical cameras, the patent creates a virtual representation of the environment using a single camera's captured image. This virtual copy provides 360-degree viewing capability through three-dimensional space projection and rotation, eliminating the need for multiple physical sensors.
Solution Approach 2:
The patent solves the coverage limitation by adding a third dimension to the image display. By projecting the two-dimensional captured image onto a three-dimensional virtual space, the system enables omnidirectional viewing without requiring multiple cameras positioned at different locations.
4Adaptability or versatility
If the graphic is placed only within the captured image area, then the manufacturing precision is maintained, but the adaptability is reduced for displaying information in uncaptured directions
Solution Approach 1:
The patent allows graphics to be placed in the third dimension of the virtual space, extending beyond the boundaries of the original two-dimensional captured image. This enables information to be displayed in directions not captured by the camera while maintaining proper spatial relationships through the three-dimensional coordinate system.

AI summary
The present disclosure is to enable to confirm a situation around a water-surface movable body also for a direction different from an imaging direction of an imaging device. A captured image inputting module accept an input of an image captured by an imaging device installed in a water-surface movable body. A position acquiring module acquire positional information indicative of a position of the water-surface movable body. A posture acquiring module acquire posture information indicative of a posture of the water-surface movable body. An additional display information acquiring module acquire additional display information including information indicative of positions of one or more locations. The synthesized image generating module generate a synthesized image where a graphic rendering a three-dimensional virtual reality object indicative of the additional display information is synthesized on the captured image based on the positional information, the posture information, and the additional display information, and when the captured image is placed partially in the synthesized image, place the graphic across a boundary of the captured image.
