Parking Space Overlay Using 3D Upward Extension Surfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing parking lot systems fail to effectively and reliably distinguish parkable and non-parkable spaces, leading to increased time consumption and potential accidents during vehicle parking, especially in crowded lots.
Innovation Solution
An information processing apparatus generates display data by superimposing graphic data, such as fence-type or box-type virtual objects, on vehicle surroundings images to clearly indicate parkable and non-parkable spaces using sensors and external information, enhancing visibility and reducing confusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If color-coded lines are used to indicate parkable and non-parkable spaces, then information can be transmitted to drivers, but the lines are difficult to recognize and may be confused with actual painted lines in the parking lot
Solution Approach 1:
The patent transitions from 2D line representations to 3D upward extension surfaces. The virtual images extend vertically from the ground position, creating a dimensional change that makes them visually distinct from flat painted lines on the parking lot surface. This dimensional differentiation resolves the confusion between virtual indicator lines and actual painted lines while maintaining effective information transmission to drivers.
Solution Approach 2:
The patent introduces asymmetric visual characteristics by giving parkable and non-parkable spaces different geometric forms (e.g., different heights, orientations, or patterns of upward extensions). This asymmetry enables drivers to quickly distinguish between parkable and non-parkable areas without confusion, addressing the recognition difficulty while preserving clear information delivery.
2Measurement precision
If drivers visually check surroundings to search for empty spaces, then they can identify parkable areas, but it takes time and increases the risk of contact accidents
Solution Approach 1:
The system performs preliminary action by pre-processing and presenting parking space information to drivers before they need to manually search. The image processing apparatus automatically identifies and displays parkable spaces using upward extension surfaces, allowing drivers to immediately see available parking areas without time-consuming visual scanning, thus reducing both search time and accident risk while maintaining accurate identification.
Solution Approach 2:
The patent replaces the mechanical visual checking process with an automated image processing system. Instead of drivers manually scanning and interpreting parking lot visuals, the system automatically captures images, processes them to generate upward extension surface representations, and presents the results, substituting human visual search with automated optical processing to eliminate time loss and improve accuracy.
3Loss of information
If multiple colored lines are painted on the parking lot surface, then parkable and non-parkable spaces can be distinguished, but drivers may confuse virtual image lines with actual painted lines
Solution Approach 1:
The patent resolves the reliability issue by moving the virtual indicator lines from the 2D ground plane to a 3D vertical dimension. The upward extension surfaces rise above the parking lot surface, creating a clear visual distinction from flat painted lines. This dimensional separation ensures drivers can reliably differentiate between virtual indicators and actual parking markings, maintaining both information delivery and distinction reliability.
Solution Approach 2:
The patent applies local quality by giving specific spatial characteristics to different types of parking spaces. Parkable and non-parkable spaces have distinct local properties in terms of upward extension geometry, position, and configuration. This localized differentiation ensures reliable distinction between space types while maintaining clear information communication to drivers.
