AR Data Processing System Position-Based Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image recognition methods for augmented reality (AR) display systems face limitations in recognizable objects, leading to high power consumption, delays in image display, increased data traffic, and privacy concerns due to the need for marker detection and extensive data transmission.
Innovation Solution
A data processing system comprising a portable terminal, a network, and a server, where position information is transmitted to the server, and corresponding object data is sent back to the terminal for comparison with imaging data, allowing for efficient AR display, reduced power consumption, and minimized data transmission by updating mismatched object data in the database.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image recognition is performed by using imaging data on a portable terminal, then image recognition function is achieved, but power consumption increases and image display is delayed
Solution Approach 1:
The patent divides the image recognition system into two parts: the portable terminal captures imaging data and transmits position information, while the server performs the computationally intensive image recognition and object data comparison. This segmentation allows the terminal to maintain recognition functionality with minimal local processing, significantly reducing power consumption.
Solution Approach 2:
The server acts as an intermediary between the portable terminal and the object database. The terminal transmits only position information to the server, which then retrieves and compares relevant object data, returning only the comparison results. This intermediary approach avoids transmitting large amounts of imaging data while maintaining recognition accuracy, reducing both power consumption and processing delay.
2Measurement precision
If image recognition is performed by transmitting imaging data to the server, then recognition accuracy is improved, but data traffic increases and privacy issues occur
Solution Approach 1:
The patent extracts only the essential position information from the imaging data and transmits it to the server, leaving the bulk imaging data local to the terminal. This extraction approach maintains recognition accuracy by enabling server-side comparison with object database entries while minimizing data traffic and avoiding privacy concerns associated with transmitting sensitive imaging data.
Solution Approach 2:
The server preliminarily retrieves object data from the database based on position information before receiving the actual imaging data for comparison. This preliminary action allows the system to prepare reference data in advance, ensuring accurate recognition while avoiding the need to transmit large amounts of imaging data over the network.
3Device complexity
If marker detection method is used for object recognition, then recognition process is simplified, but recognizable objects are limited
Solution Approach 1:
The patent creates a virtual copy of the real-world environment by storing object data (including images, positions, and attributes) in a database on the server. The portable terminal captures imaging data and compares it with these stored copies, enabling recognition of any object that has been previously registered in the database, thus vastly expanding the recognizable objects range while keeping the terminal's processing complexity low.
Solution Approach 2:
The server-based recognition system serves multiple functions: it stores diverse object data in the database, performs image comparison, corrects position information, and provides AR display data. This universal approach allows the same system to recognize various types of objects (buildings, landmarks, artworks, etc.) without requiring different recognition methods, enhancing versatility while maintaining process simplicity.
Data Source
AI summary
An object is to provide a novel data processing system. The data processing system includes a portable terminal, a network, a server, and a database. The portable terminal transmits position information to the server through the network. The server transmits, to the portable terminal through the network, a plurality of pieces of object data corresponding to the position information obtained from the database. Imaging data obtained by the portable terminal and the plurality of pieces of object data are compared, and when there is a piece of the object data that does not match the imaging data, the mismatched piece of the object data stored in the database is updated.
