Vehicle Surround View Image Standardization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surround view systems for vehicles provide inaccurate images when viewed from a user terminal, particularly at the boundaries, due to unclear information and varying camera viewpoints.
Innovation Solution
A vehicle system comprising a communicator, camera, and controller that converts surrounding images into standardized reference images using predetermined parameters, and a user terminal that receives these images, generates matrices for virtual camera viewpoints, and adjusts the viewpoint based on user commands to output accurate and clear images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If surround view images are provided through user terminal with virtual camera viewpoint, then remote identification is enabled, but image accuracy deteriorates especially at boundaries
Solution Approach 1:
The patent introduces an intermediary processing system that includes coordinate transformation modules and matrix generation units. These intermediaries convert images from multiple physical cameras into a standardized reference image coordinate system, ensuring accurate boundary representation while enabling remote viewing through user terminals.
Solution Approach 2:
The system dynamically adjusts viewpoint parameters and camera position parameters through matrix transformations. By changing these parameters, the system can provide different virtual camera viewpoints while maintaining image accuracy through proper coordinate system transformations and reference image generation.
2Area of stationary object
If multiple cameras are used to capture surround view, then comprehensive coverage is achieved, but image inconsistency at boundaries occurs
Solution Approach 1:
The patent merges images from multiple cameras by transforming them into a unified reference image coordinate system. The controller generates a standardized reference image that integrates information from all cameras, ensuring consistent boundary representation and comprehensive surround coverage through coordinate alignment.
Solution Approach 2:
The system creates a virtual reference image that copies and integrates information from all physical cameras. This reference image serves as a standardized representation that maintains consistency across all viewpoints while preserving the comprehensive coverage provided by multiple cameras.
3Ease of operation
If viewpoint adjustment is allowed based on user command, then user control flexibility increases, but image reliability decreases when command exceeds predetermined range
Solution Approach 1:
The system dynamically adjusts the virtual camera viewpoint within predetermined ranges based on user commands. The viewpoint parameters are modified in real-time to provide flexible control, while the system maintains reliability by constraining adjustments within validated parameter ranges that ensure image quality and accuracy.

AI summary
A vehicle provides a standardized and accurate image around the vehicle by changing an image obtained by the vehicle to a single reference and providing the changed image to a user terminal. The vehicle includes a communicator that communicates with the user terminal or a server and a camera that obtains an image around the vehicle. A controller then converts a surrounding image obtained by the camera into a reference image implemented with a predetermined parameter and transmits the reference image to the user terminal.
