Vehicle Window Display Alignment for Immersive AR Scenery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for associating pictures with geographic information, such as scenery and buildings, fail to provide value-added information to occupants of moving bodies as they only superimpose pictures without enhancing the occupant's experience.
Innovation Solution
A display device and method that provides a virtual object corresponding to scenery or objects seen by occupants of moving bodies, using a display system with a display controller that determines and displays virtual objects based on the positional relationship between the object and the moving body, allowing for enhanced immersion and information provision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pictures are superimposed onto scenery without considering the moving body's position, then the display process is simple, but the immersion and accuracy of the virtual object relative to the real scenery deteriorate
Solution Approach 1:
The patent replaces complex manual positioning methods with automated image processing and coordinate transformation algorithms. The display controller automatically calculates the positional relationship between the moving body and scenery by processing image data and performing coordinate transformations, substituting mechanical positioning with computational methods to achieve high accuracy without excessive complexity
Solution Approach 2:
The system performs self-positioning and self-alignment by automatically calculating the relative position between the moving body and the scenery based on captured images. The display controller autonomously determines the correct display position of virtual objects without requiring external intervention, making the system self-sufficient in maintaining accurate positioning
2Stability of the object's composition
If virtual objects are displayed without considering the moving body's movement, then the display system is simple, but the consistency between virtual object position and real scenery position deteriorates
Solution Approach 1:
The system continuously captures images of the scenery and uses the display controller to calculate the current positional relationship between the moving body and the scenery. This feedback loop ensures that the virtual objects are consistently positioned relative to the real scenery by constantly updating the display based on the latest position information
Solution Approach 2:
The patent implements a dynamic display system that automatically adapts to the moving body's movement. The display controller continuously updates the virtual object positions based on real-time positional calculations, making the system dynamic and responsive to changes in the moving body's position while maintaining consistency
3Adaptability or versatility
If conventional picture superposition is used, then the implementation is simple, but the value-added information and occupant experience deteriorate
Solution Approach 1:
The display device serves multiple functions: it displays the real scenery, superimposes virtual objects with accurate positional relationships, and provides value-added information to occupants. By integrating these functions into a single system that processes image data and performs coordinate transformations, the patent achieves multi-functionality without proportionally increasing complexity
Solution Approach 2:
The display controller acts as an intermediary that processes raw image data, calculates positional relationships, and generates the final composite display. This intermediary component coordinates between the image capturing device and the display device, enabling enhanced occupant experience through a manageable level of complexity
