Vehicle Surround-View Display with Dynamic Projection Planes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display control systems for vehicles often result in the disappearance or double-imaging of surrounding vehicles in combined images from multiple camera views, leading to confusion for the driver due to discontinuities and distortions at image joints.
Innovation Solution
A display control apparatus that includes a vehicle detector and an image processor, which sets a second projection plane for detected surrounding vehicles, generates a surrounding vehicle image by projecting captured images onto this plane, and superimposes it on a background image, using blending techniques to prevent disappearance and double-imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single projection plane is set behind the vehicle for combining multiple camera images, then the image combination process is simplified, but surrounding vehicles may disappear or appear as double-images causing driver confusion
Solution Approach 1:
The system dynamically switches between a first projection plane (for normal operation) and a second projection plane (when surrounding vehicles are detected). This dynamic adjustment allows the system to maintain simplified processing while ensuring reliable vehicle detection by adapting the projection plane based on detected vehicle positions
Solution Approach 2:
The system uses different projection planes for different regions/scenarios: the first projection plane is used for general background imaging, while the second projection plane is specifically used when surrounding vehicles are detected. This local differentiation ensures that each region is processed with the most appropriate method for its specific requirements
2Manufacturing precision
If the projection plane is set to match the position of surrounding vehicles, then double-imaging is avoided, but the background image may become distorted or discontinuous
Solution Approach 1:
The system segments the image processing into two distinct parts: background image generation using the first projection plane, and surrounding vehicle image generation using the second projection plane. This segmentation allows each part to be optimized independently - the background maintains continuity while vehicles are accurately positioned without distortion
3Measurement precision
If multiple projection planes are used to prevent vehicle disappearance, then detection accuracy improves, but the image processing complexity increases
Solution Approach 1:
Rather than continuously using multiple projection planes, the system dynamically selects which projection plane to use based on whether surrounding vehicles are detected. This reduces processing complexity while maintaining high detection accuracy when needed
Solution Approach 2:
The system applies different processing methods locally: using the second projection plane only in the specific case when surrounding vehicles are detected, while using the first projection plane for all other scenarios. This localized approach maintains precision without unnecessarily increasing overall system complexity

AI summary
A display control apparatus includes a vehicle detector and a processor, the processor generating a background image of a vehicle, setting, when a surrounding vehicle is detected in a predetermined region, a second projection plane to a position at which the surrounding vehicle is detected, generating a surrounding vehicle image by projecting a plurality of captured images onto the second projection plane, and superimposing the surrounding vehicle image on the background image.
