Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality systems in mobile vehicles face challenges in accurately estimating the relative positional relationships between physical objects and users due to incorrect image recognition and insufficient positioning precision, leading to overlapping errors and discomfort in viewing virtual information.
Innovation Solution
An information display system comprising a light transmitting display, image capturing device, positioning device, and processing device, which calculates reference position information and performs object recognition processing to determine the display position of virtual information on the display, using a combination of GPS and image recognition technologies to enhance accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single positioning technology (GPS or image positioning) is used to determine the relative positional relationship, then the device complexity is reduced, but the positioning precision deteriorates due to incorrect image recognition or insufficient samples
Solution Approach 1:
The patent combines GPS positioning technology and image positioning technology into a unified positioning system. The processing device integrates position information from GPS with recognition results from image processing to determine the relative positional relationship between the vehicle and target objects, thereby improving positioning precision while maintaining reasonable system complexity
Solution Approach 2:
The positioning device is designed to perform multiple functions: it can operate using GPS alone, image positioning alone, or both together. This multi-functional capability allows the system to adapt to different scenarios and maintain high positioning precision across various conditions without significantly increasing complexity
2Adaptability or versatility
If image positioning technology is used to recognize target objects, then the adaptability to different target objects is improved, but the reliability deteriorates due to incorrect image recognition or insufficient number of samples
Solution Approach 1:
The system uses feedback from GPS positioning to verify and correct image recognition results. When the processing device receives position information from GPS and recognition results from image processing, it compares and validates them against each other, improving reliability by using the more accurate modality to correct potential errors in the other
Solution Approach 2:
The patent prepares multiple positioning and recognition methods in advance (GPS, image positioning, object database) to cushion against the unreliability of any single method. If image recognition fails or produces incorrect results, the system can fall back on GPS positioning or query the object database, ensuring continued reliable operation

AI summary
A method, a processing device, and a system for information display are proposed. The information display system is installed on a mobile vehicle and includes a light transmitting display, an image capturing device configured to capture a target image of a target object, a positioning device configured to generate position information of the mobile vehicle, and a processing device configured to perform the following operations. First reference position information of the target object is calculated according to the position information of the mobile vehicle. Object recognition processing is performed on the target image. A display position of virtual information of the target object is determined using a recognition result of the object recognition processing or the first reference position information according to the recognition result of the object recognition processing. The virtual information is displayed through the light transmitting display according to the display position of the virtual information.
