Surround View Video Processing With Adjustable Circuit Viewpoints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle video shooting methods, particularly for circuit driving, are limited by the use of a single front camera and lack dynamic surround view capabilities, which restricts their application to specific environments and speeds, and do not allow for user-adjustable viewpoints or comprehensive circuit map generation.
Innovation Solution
A system and method that processes multiple vehicle exterior videos to create a surround view video with adjustable viewpoints, integrates a virtual model of the vehicle, and generates circuit maps and tracking lines, enabling dynamic viewing and enhanced user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single front camera is used for video shooting, then the device complexity is reduced, but the view coverage and information completeness deteriorate
Solution Approach 1:
The patent merges multiple camera feeds (front, rear, left, right cameras) into a single integrated surround view video stream. This combining approach provides comprehensive 360-degree coverage while maintaining manageable system complexity through unified processing and display.
Solution Approach 2:
The camera system is designed to serve multiple functions: it can operate as a standard front camera for normal driving, activate surround view mode when the vehicle stops, and provide circuit driving mode for racing applications. This multi-functionality addresses information completeness across different operating scenarios.
2Loss of information
If cameras are positioned for surround view shooting, then the view coverage is improved, but the device complexity increases
Solution Approach 1:
The system dynamically activates surround view mode based on vehicle operating conditions (when the vehicle stops). This dynamic approach provides comprehensive coverage when needed while maintaining simpler operation during normal driving, effectively managing the complexity-coverage trade-off.
Solution Approach 2:
The system changes operational parameters based on driving mode: in circuit driving mode, it provides continuous surround view capability at higher speeds, whereas in normal mode it activates only when stopped. This parameter-based control optimizes the balance between coverage and complexity.
3Adaptability or versatility
If surround view video is activated at high speeds, then the adaptability is improved, but the safety and reliability deteriorate
Solution Approach 1:
The system implements speed-based parameter changes: surround view activation threshold is set at 20 km/h for normal driving (providing safety by limiting activation at low speeds) but allows higher speed operation in circuit driving mode. This conditional parameter adjustment resolves the contradiction between adaptability and safety.
4Ease of operation
If viewpoint adjustment is added to surround view video, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The viewpoint adjustment mechanism allows dynamic repositioning of the virtual camera angle within the surround view display. Users can adjust the viewpoint to see different perspectives of their vehicle and surroundings, enhancing ease of operation through flexible control while the system handles the processing complexity.

AI summary
A method for processing video obtained by circuit driving includes receiving a plurality of videos taken by shooting an outside of a vehicle, receiving input by a user for moving a viewpoint of a first surround view video, creating a second surround view video having the viewpoint moved from the first surround view video based on the plurality of videos and the input by the user, and providing the second surround view video, where the first surround view video and the second surround view video display both the outside of the vehicle and a virtual model of the vehicle through processing of the plurality of videos.
