Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed virtual perspective is used for displaying vehicle surroundings, then the system structure is simple, but the user cannot view images from desired angles
Solution Approach 1:
The patent implements a dynamic virtual perspective system where the viewpoint can be freely changed in three-dimensional space based on user input. The virtual camera position and orientation are dynamically adjusted to allow viewing from any desired angle, transforming the fixed perspective into a flexible, user-controllable viewing experience.
Solution Approach 2:
The patent introduces a virtual camera as an intermediary between the captured images and the user's view. This virtual camera synthesizes the surrounding image from multiple camera inputs and allows the user to control its position and orientation, effectively mediating between the fixed physical cameras and the flexible viewing requirements.
2Area of stationary object
If multiple cameras are used to capture surroundings, then the coverage area is improved, but the image synthesis complexity increases
Solution Approach 1:
The patent merges images from multiple physical cameras into a single synthesized surrounding image viewed from a virtual perspective. By combining the image data and processing them through coordinate transformations and perspective adjustments, the system achieves comprehensive coverage while presenting a unified view to the user.
Solution Approach 2:
The patent creates a virtual copy of the physical camera system in the digital domain. The virtual camera replicates the function of capturing images but operates in software, allowing flexible positioning and orientation without additional physical hardware. This virtual copying enables comprehensive coverage with controlled synthesis complexity.
3Ease of operation
If the virtual perspective position is changed frequently, then the user can find desired viewing angles, but the processing time increases
Solution Approach 1:
The patent performs preliminary actions by pre-processing the images from multiple cameras into a standardized format suitable for virtual perspective synthesis. By preparing the image data in advance with proper coordinate system alignment and calibration, the system reduces the computational burden during real-time perspective changes, enabling faster regeneration when the user adjusts the viewing angle.

AI summary
A plurality of images of an imaging subject are captured by using a plurality of cameras. The plurality of images are synthesized to generate a synthesized image viewing the imaging subject from a virtual perspective. The synthesized image is displayed on a screen. When a user operation for changing the position of the virtual perspective is detected, the position of the virtual perspective in the synthesized image is changed.
