Parking View Synthesis for Accurate Space Boundary Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle parking assistance systems face challenges in providing accurate parking assistance, especially in poor environmental conditions like nighttime or rainy weather, due to limitations in camera imaging and increased difficulty in detecting parking space boundaries.
Innovation Solution
A vehicle parking assistance apparatus that includes a first imager for capturing a frontward view, a second imager for capturing a rearward view, and a vehicle controller that generates synthetic data by synthesizing parking space data from the first imager with rearward view data from the second imager, and displays this synthetic data to assist the driver in parking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only a front camera is used for parking assistance, then the device complexity is reduced, but the measurement precision of parking space boundaries deteriorates in poor environmental conditions
Solution Approach 1:
The patent combines image data from both the front camera and rear camera to generate synthetic views that display parking space boundaries. The controller synthesizes the front camera image data showing forward parking spaces with the rear camera image data, creating a composite display that provides accurate boundary detection even in poor lighting conditions where a single camera would fail.
2Measurement precision
If multiple cameras are used to improve detection accuracy, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
The front camera serves dual purposes: capturing images for forward viewing display and providing image data for synthesizing parking space boundary information. The rear camera similarly provides both rearward viewing capability and contributes to the synthetic display generation. This multi-functionality reduces the need for additional dedicated sensors while maintaining high detection accuracy.
3Measurement precision
If synthetic data is generated by combining front and rear camera data, then the measurement precision of parking space boundaries improves, but the device complexity and processing requirements increase
Solution Approach 1:
The controller continuously acquires and processes image data from both cameras in advance, generating synthetic views that are ready for immediate display. By performing the synthesis operation continuously and preliminarily, the system avoids complex real-time processing delays when the driver needs parking assistance information, simplifying the real-time control requirements.

AI summary
A vehicle parking assistance apparatus is configured to provide parking assistance when parking a vehicle in a parking space. The vehicle parking assistance apparatus includes first and second imagers, a display, and a vehicle controller. The first imager is configured to provide capture a frontward view of the vehicle. The second imager is configured to provide capture a rearward view of the vehicle. The display is configured to provide display at least first imaging data and second imaging data the first imager and the second imager respectively. The vehicle controller is configured to provide calculate parking space data regarding the parking space, using the first imaging data. The vehicle controller is configured to, when detecting shifting of the vehicle to a reverse range, generate synthetic data in which the parking space data is synthesized with the second imaging data, and display the synthetic data on the display.
