3D Parking Space Display Occlusion Handling for Clear Slot Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 3D parking displays, vehicle models often obscure available parking space frames, leading to poor visibility and a diminished user experience due to occlusion.
Innovation Solution
Display a first planar parking space contour for available spaces and a 3D occupancy model for unavailable spaces, and perform occlusion processing by adjusting the display of these models based on the current viewing perspective to enhance visibility of available spaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If parking space information is displayed on the head-up display device, then the driver can see parking space information without taking eyes off the road, but the display area is limited and information may be obscured
Solution Approach 1:
The patent transitions the display from a two-dimensional head-up display surface to a three-dimensional virtual image space. The virtual parking guidance mark is projected into the spatial environment ahead of the vehicle, allowing the display to extend beyond the limited physical HUD surface area while maintaining the benefit of not requiring the driver to move their eyes or head.
2Loss of information
If detailed parking space information is displayed, then the driver receives comprehensive guidance, but the information may be obscured by external light or other factors
Solution Approach 1:
The patent employs color changes in the virtual parking guidance mark to convey different information states and maintain visibility. The virtual image can change color to indicate parking space status (available, occupied, reserved) and to enhance contrast against different background conditions, reducing the impact of external light interference.
Solution Approach 2:
The patent introduces a virtual image as an intermediary between the driver and the actual parking environment. This virtual representation is superimposed on the real-world view through the HUD, allowing information to be displayed without being directly affected by external light conditions that would obscure physical displays.
3Measurement precision
If the vehicle captures images of the parking environment, then accurate parking space information can be obtained, but the image processing increases computational load
Solution Approach 1:
The patent extracts only the essential features needed for parking space detection from the captured images, rather than performing comprehensive image analysis. The image processing focuses specifically on identifying parking space boundaries, occupancy status, and relevant geometric features, reducing computational requirements while maintaining detection accuracy.

AI summary
A parking space display processing method and a vehicle are provided. The method includes: displaying a first planar parking space contour for an available parking space and displaying a 3D occupancy model for an unavailable parking space when a vehicle starts 3D parking; determining whether a target 3D occupancy model occludes a contour line of a target first planar parking space contour based on a current display perspective; and performing display occlusion processing when it is determined that the target 3D occupancy model occludes the contour line of the target first planar parking space contour. According to the invention, highlighted display of occluded available parking spaces in 3D parking is achieved, the visibility of occluded available parking space frames in 3D space is enhanced, and user's parking experience is improved.
