AR Anchor Smart Device Control for Angle-Independent Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for controlling smart devices, such as hardware switches and remote controls, are inefficient and fail to accurately control devices due to the need for manual search and angle-dependent image identification, especially when multiple devices of the same type are present.
Innovation Solution
A device control method and apparatus using AR anchors created based on spatial locations, allowing for the acquisition of AR anchors in images captured by a terminal, determining the target device, displaying its control menu, and generating control instructions for efficient device control, independent of the camera's angle or position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional hardware switches or remote controls are used to control smart devices, then the control method is simple, but the control efficiency is low and cannot satisfy users' efficient control needs
Solution Approach 1:
The patent replaces traditional mechanical control methods (hardware switches, remote controls) with an AR-based visual recognition system. The terminal device captures images, recognizes device features through image processing, and presents control options virtually, substituting mechanical interaction with optical recognition and digital processing to achieve faster, more efficient device control
Solution Approach 2:
The patent introduces an AR control interface as an intermediary between the user and the smart device. Instead of direct mechanical control, the system processes images, identifies devices, and presents virtual control menus that mediate the interaction, enabling efficient control while maintaining system manageability
2Ease of operation
If the control menu is found through mobile phone APP, then the device can be controlled, but the operation process is complex and time-consuming
Solution Approach 1:
The patent performs preliminary actions by pre-processing device features and storing them for rapid matching. When a device is captured in an image, the system can quickly retrieve and match device features without requiring users to manually search through apps, significantly reducing the time to locate and control devices
Solution Approach 2:
The patent creates a visual copy of the device control interface directly over the captured image. Instead of navigating to separate control menus in an APP, the system overlays virtual control buttons and information directly on the device image, allowing users to control devices immediately without additional navigation steps
3Measurement precision
If device image identification is used to control smart devices, then the device can be identified, but the identification is angle-dependent and cannot accurately control devices when multiple devices of the same type are present
Solution Approach 1:
The patent transitions from two-dimensional image pattern recognition to three-dimensional spatial feature recognition. By extracting spatial coordinates, depth information, and positional relationships from images, the system can identify devices from any angle and distinguish between multiple devices of the same type based on their spatial locations, achieving both high accuracy and angle independence
Solution Approach 2:
The patent segments the device identification process into multiple independent feature extraction steps: spatial position extraction, device feature extraction, and matching operations. This segmentation allows the system to process multiple devices simultaneously and accurately distinguish between them based on their unique spatial and feature characteristics
