Solution Overview

Problem

Existing vehicle parking display systems provide a poor user experience due to rigid and unnatural switching between multiple angles of view, resulting in image flickering and a poor visual effect.

Innovation Solution

A three-dimensional parking display method that determines an initial and final angle of view for a virtual camera based on a parking start instruction, calculates a transition angle of view using a switching benchmark and ratio, and displays a series of image frames to smoothly transition between these angles, improving the visual coherence and user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple angles of view are switched directly during parking display, then the parking scenario can be viewed from different perspectives, but the switching is rigid and unnatural causing image flickering and poor visual effect

Engineering Contradiction:
Improvemulti-angle viewing capabilityVSAvoidvisual smoothness
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies dynamics by transitioning from static angle switching to dynamic continuous angle transition. The virtual camera's angle of view changes continuously over time according to a transition function, creating smooth visual transitions between different viewing angles during the parking process, thereby eliminating rigid switching and image flickering

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of camera angle from discrete fixed values to continuous varying values. By introducing a transition function that varies the camera angle continuously based on time and parking progress, the system achieves natural visual transitions while maintaining multi-angle viewing capability

Inventive Principle:
Principle #35Parameter changes

2Loss of information

If multiple angles of view are switched directly during parking display, then different perspectives are available, but image flickering occurs reducing user experience

Engineering Contradiction:

Solution Approach 1:

The patent ensures continuity of useful action by making the camera angle transition continuous rather than discrete. The virtual camera smoothly transitions between angles throughout the parking process, maintaining continuous visual information without interruption or flickering, thereby improving both information continuity and image stability

Inventive Principle:

Solution Approach 1:

The patent introduces dynamic angle transition control where the camera angle varies continuously based on time and parking progress. This dynamic approach significantly improves visual quality by eliminating rigid switching effects, while the underlying implementation remains computationally straightforward using basic interpolation functions

Inventive Principle:
Principle #15Dynamics

AI summary

The present disclosure discloses a three-dimensional parking display method, a vehicle, and a storage medium. The three-dimensional parking display method includes: determining an initial angle of view and a final angle of view of a virtual camera to a three-dimensional parking scenario based on an obtained parking start instruction; determining a transition angle of view based on the initial angle of view and the final angle of view; and displaying a plurality of image frames of the three-dimensional parking scenario drawn by the virtual camera based on the initial angle of view, the transition angle of view, and the final angle of view. Therefore, a parking picture is adapted to a real parking scenario, and switching between the initial angle of view and the final angle of view is smooth and natural. In this way, the visual effect is better, which is beneficial to improve user experience.
