Vehicle Surrounding Camera Image Switching for Obstacle Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicle surrounding monitoring systems, overlapping regions between adjacent cameras create unclear displays of objects in bird's-eye view images, making it difficult for drivers or vehicle control devices to confirm the presence or absence of obstacles, especially when the vehicle's passage region overlaps with an object.
Innovation Solution
A vehicle control device that combines images from multiple cameras to generate a surrounding screen image, includes a collision determination unit to assess obstacles on the vehicle's route, and switches between a standard and alarm screen image based on obstacle presence, using specific camera images to highlight obstacles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a bird's-eye view screen image is generated by combining images from multiple cameras with overlapping regions, then the overall surrounding view is continuous and recognizable, but objects in the overlapping regions cannot be clearly displayed and their details cannot be confirmed
Solution Approach 1:
The system segments the display into two types: the overall bird's-eye view screen image for continuous surrounding monitoring, and a magnified screen image that segments and enlarges specific regions containing objects. This allows simultaneous achievement of overall continuity and local detail clarity.
Solution Approach 2:
The system transitions from a two-dimensional bird's-eye view to a magnified view that effectively adds a dimensional perspective by enlarging specific regions. This dimensional change allows objects in overlapping regions to be viewed with sufficient detail for identification while maintaining the overall contextual view.
2Extent of automation
If the vehicle control device relies on the bird's-eye view screen image for automatic control, then automated navigation is enabled, but the driver cannot instantly determine appropriate response when obstacles are present in overlapping regions
Solution Approach 1:
The system performs preliminary detection to identify objects in overlapping regions, and when such objects are detected, it proactively generates and displays the magnified screen image before the driver needs to make a decision. This preliminary action reduces the driver's response time by providing critical information in advance.
Solution Approach 2:
The system provides feedback to the driver by detecting objects in overlapping regions and automatically generating magnified views when necessary. This feedback mechanism ensures the driver receives timely information about potential obstacles, enabling faster response while maintaining automated control functions.
3Area of stationary object
If the system displays only the bird's-eye view screen image, then the overall surrounding situation is visible, but it is difficult to confirm the presence or absence of obstacles in the vehicle's passage region
Solution Approach 1:
The display system segments the visual information by creating a magnified screen image that focuses on specific regions containing objects from the overlapping areas. This segmentation allows the system to maintain comprehensive coverage while providing enhanced detail for obstacle detection in critical regions.
Solution Approach 2:
The system applies local quality enhancement by generating magnified views specifically for regions where objects are detected in overlapping camera fields. This allows different parts of the display to have different levels of detail - the overall bird's-eye view maintains broad coverage while localized regions provide high-detail obstacle confirmation.
