Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bird's-eye view video generation technologies face challenges in accurately generating continuous videos when the positional relationship of imaging devices changes, leading to discontinuous connections and difficulties for drivers to check vehicle surroundings effectively.
Innovation Solution
A video generation system that includes multiple imaging devices mounted on movable parts of a vehicle, a detection unit for movement, and a processing unit that synthesizes videos by adjusting the orientation of captured images based on detected movement, ensuring continuous and accurate bird's-eye view video generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If imaging devices are mounted on movable parts of a vehicle, then the system can capture videos from dynamic positions, but the bird's-eye view video becomes discontinuous and inaccurate when the positional relationship changes
Solution Approach 1:
The patent applies dynamics by making the video orientation adjustable based on the actual positional relationship between imaging devices. Instead of fixing video orientation to predetermined directions, the system dynamically adjusts video orientation according to detected movement of movable parts, allowing the bird's-eye view video to remain accurate despite changes in imaging device positions.
2Manufacturing precision
If the imaging device position is fixed along a predetermined direction, then accurate bird's-eye view video can be generated, but the system cannot adapt when the positional relationship of imaging devices changes
Solution Approach 1:
The system transitions from a static predetermined orientation to a dynamic adjustable orientation. The video orientation is no longer fixed but is adjusted based on detection information about the actual positional relationship between imaging devices, enabling both accuracy and adaptability.
Solution Approach 2:
The patent implements feedback by using detection information about the positional relationship between imaging devices to adjust video orientation. The system continuously monitors the actual positions and adjusts the video orientation accordingly, creating a closed-loop control system that maintains video accuracy despite positional changes.
3Area of stationary object
If multiple imaging devices are used to capture videos from different positions, then comprehensive vehicle surroundings can be monitored, but the connecting portions between videos become discontinuous
Solution Approach 1:
The system uses detection information about the positional relationships between multiple imaging devices to adjust video orientations. This feedback mechanism ensures that videos from different positions are oriented correctly relative to each other, maintaining continuity at connecting portions while preserving comprehensive monitoring coverage.

AI summary
A device includes a video acquiring unit 42 that is arranged on a vehicle and acquires videos captured by imaging units 10, at least one of the imaging devices being mounted on a movable part that is movable with respect to a body of the vehicle, a vehicle information acquiring unit 43 that acquires detection information indicating that movement of the movable part is detected, a bird's-eye view video generating unit 44 that generates a synthesized video by synthesizing the videos that are captured by the imaging units 10 and are acquired by the video acquiring unit 42, and a display control unit 45 that displays the synthesized video generated by the bird's-eye view video generating unit 44 on the display panel 31. When the vehicle information acquiring unit 43 acquires detection information indicating that the movement of the movable part is detected, the bird's-eye view video generating unit 44 generates a synthesized video by changing orientation of a video that is captured by the imaging unit 10 mounted on the movable part in which the movement is detected.
