Vehicle Door Opening Collision Warning Using Surround View Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Smart vehicles often collide with adjacent vehicles when opening doors, leading to scratches and economic losses due to the lack of effective collision prevention systems compared to traditional vehicles.
Innovation Solution
A vehicle door-opening anti-collision method and apparatus that establishes a surround view interface diagram, identifies obstacles, and determines the risk of collision by comparing the obstacle's contour range with the door opening/closing range, providing warning prompts to prevent collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If door opening/closing operation is performed without collision detection, then ease of operation is improved, but object-affected harmful factors worsen due to collision damage
Solution Approach 1:
The system performs preliminary detection of obstacles in the door opening path before the actual door opening operation. The contour range identification and overlapping area calculation are completed in advance, allowing the system to issue warnings or prevent door opening before collision occurs, thus resolving the contradiction between ease of operation and prevention of harmful effects
Solution Approach 2:
The system continuously monitors the surrounding environment and provides real-time feedback about potential collision risks. By calculating the overlapping area between the door opening range and obstacle contour range, the system gives feedback to the driver through warnings, enabling the driver to adjust the door opening action to avoid collision while maintaining operational convenience
2Object-affected harmful factors
If collision prevention system is implemented, then object-affected harmful factors are reduced, but device complexity increases
Solution Approach 1:
The system uses a multi-functional approach where the same image processing and contour detection algorithms serve multiple purposes: obstacle detection, contour range identification, and overlapping area calculation. This universal application of core processing functions reduces the need for separate dedicated components for each function, thereby limiting the increase in device complexity while achieving comprehensive collision prevention
Solution Approach 2:
The system creates a digital copy or representation of the physical environment through imaging and contour range identification. By working with these digital representations and calculating overlapping areas in the digital domain, the system avoids the need for complex physical sensors and mechanical prevention mechanisms, thus reducing device complexity while effectively preventing collision damage
3Measurement precision
If contour range identification is performed on obstacles, then measurement precision is improved, but loss of time increases due to processing requirements
Solution Approach 1:
The system performs partial contour range identification by focusing on the critical portions of obstacles that may intersect with the door opening path. Rather than fully processing and identifying every detail of every obstacle, the system calculates only the overlapping area between the door opening range and obstacle contours, which provides sufficient measurement precision for collision prevention while significantly reducing processing time

AI summary
The disclosure provides a vehicle door-opening anti-collision method and apparatus, a vehicle (100) , and a storage medium (300). The method includes: establishing a surround view interface diagram for the vehicle (S110); obtaining an image of an obstacle around the vehicle when the vehicle is in a stopped state (S120); performing an identification on the image of the obstacle to obtain an contour range of the obstacle in the surround view interface diagram (S130); and determining, when an overlapping area exists between the contour range and a door opening/closing range, that a risk of collision exists for opening a door of the vehicle, and determining a corresponding risk warning (S140). In the present disclosure, by determining whether the overlapping area exists between the contour range of the obstacle around the vehicle and the door opening/closing range, it is determined whether the risk of collision exists for opening the door of the vehicle, thereby reducing the risk of collision for opening the door of the vehicle.
