Driver Assistance Apparatus Using V2V Image Merging for Expanded Visual Field
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver assistance systems, such as Around-view Monitoring (AVM) systems, have limited utility due to the restricted field of view, primarily benefiting only in parking and low-speed driving, as they cannot capture images of wider areas beyond the camera's range, necessitating a solution to provide a broader visual field for enhanced safety and convenience.
Innovation Solution
A driver assistance apparatus comprising cameras to capture a main image and a communication unit to receive sub-images from other vehicles, with a processor generating an expanded image by combining the main and selected sub-images based on predetermined conditions or user input, thereby covering blind spots and areas outside the primary camera's range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cameras are mounted to capture images around the vehicle, then the driver can receive assistance operating the vehicle, but the space that can be included in the around-view screen is very limited
Solution Approach 1:
The patent combines images from multiple sources: local cameras mounted on the vehicle and remote cameras from other vehicles. The image processing unit merges these different image sources to create an expanded around-view screen that covers areas beyond what a single vehicle's cameras can capture, thereby increasing visual field coverage while maintaining driver assistance capability
Solution Approach 2:
The patent introduces communication units and image processing units as intermediaries to receive, process, and integrate images from other vehicles. These intermediary components enable the system to access and utilize remote camera data, expanding the visual field without requiring additional physical camera mounting space on the host vehicle
2Ease of operation
If the around-view screen is used for parking and slow speed driving, then the driver receives assistance, but the utilization is limited to a few situations
Solution Approach 1:
The patent enhances the versatility of the around-view monitoring system by enabling it to function effectively across multiple driving scenarios. By integrating remote vehicle images, the system provides comprehensive visual coverage that is useful not only for parking and slow-speed driving but also for higher-speed maneuvers and situations requiring extended blind spot monitoring, making the system universally applicable across diverse operating conditions

AI summary
Disclosed are a driver assistance apparatus and a control method for the same. The driver assistance apparatus includes at least one camera configured to generate a main image by capturing an image of a periphery of a vehicle, a communication unit configured to receive a plurality of sub images generated by at least one other vehicle, and a processor configured to: select at least one of the sub images based on a predetermined condition or user input; and to generate an expanded image using the main image and the selected sub image.
