Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality applications on vehicles face challenges in correct initialization and display due to environmental factors such as poor lighting and weather conditions, which hinder accurate edge matching.
Innovation Solution
A system comprising a mobile terminal with sensors to capture physical data and a predefined fixed point on the vehicle, using a computing unit to evaluate this data and display AR contents in a contact-analog manner, thereby avoiding computationally intensive edge matching and ensuring robust AR content display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If edge matching is used for AR initialization, then AR contents can be displayed on the vehicle, but accurate initialization is hindered by poor lighting and weather conditions
Solution Approach 1:
The patent introduces a predefined fixed point on the vehicle as an intermediary target for the capture unit. This fixed point serves as a reliable reference that is independent of environmental conditions, allowing the system to accurately determine the mobile terminal's position relative to the vehicle without being affected by lighting or weather variations that hinder edge matching
2Reliability
If edge matching is used for AR initialization, then AR contents can be displayed on the vehicle, but the process becomes computationally intensive
Solution Approach 1:
The patent extracts the initialization process from complex edge matching algorithms to a simpler fixed point capture approach. By isolating the key requirement (determining relative position) and addressing it through a dedicated fixed point target, the system eliminates the need for computationally intensive edge detection and matching operations
3Measurement precision
If fixed point capture is used instead of edge matching, then initialization accuracy is improved, but the system requires a predefined fixed point on the vehicle
Solution Approach 1:
The patent applies preliminary action by pre-defining a fixed point on the vehicle before the AR application is used. This fixed point is established in advance as a reliable reference marker, allowing the system to quickly and accurately initialize without being affected by environmental conditions. The fixed point serves as a pre-prepared solution that eliminates the need for complex real-time environmental analysis
