Camera-Based Entity Card Recognition for Virtual Object Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies require complex user operations to view target objects in application programs, resulting in low presentation efficiency, especially when multiple target objects are present in a background.
Innovation Solution
A method and apparatus that utilize a camera and display screen to photograph an entity card, obtain image interpretation data of a target object, match it with prestored data, and render the corresponding virtual target object on the screen, allowing automatic presentation without user complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user opens a corresponding window and enters parameters to view a target object in an application program, then the target object can be obtained by matching, but the operation complexity increases and presentation efficiency decreases
Solution Approach 1:
The patent replaces the manual mechanical operation of opening windows and entering parameters with an optical recognition system. The camera captures an image of the target object, and image processing algorithms automatically identify and retrieve the target object information, substituting physical user actions with automated optical and computational processes.
Solution Approach 2:
The system enables self-service by allowing the target object to be automatically recognized and retrieved through image capture. The camera and image processing system perform the identification and retrieval functions autonomously without requiring user intervention to open windows or input parameters, making the system serve itself in the information retrieval process.
2Loss of time
If manual parameter entry is required to identify target objects, then accuracy can be maintained, but time consumption increases
Solution Approach 1:
The patent applies preliminary action by pre-processing and storing target object images and their corresponding information in a database before recognition is needed. When a target object needs to be identified, the system compares the captured image against pre-processed reference images, enabling rapid and accurate identification without requiring manual parameter entry or real-time complex processing.
Data Source
AI summary
Embodiments of this application disclose a target object rendition method performed by an electronic device having a camera and a display screen. The electronic device photographs an entity card by using a camera. From the photograph, the electronic device obtains a to-be-recognized target object that is printed on the entity card and then image interpretation data of the to-be-recognized target object, the image interpretation data being used to reflect a feature of the to-be-recognized target object. After matching the image interpretation data with prestored image interpretation data, the electric device obtains a prestored target object corresponding to prestored image interpretation data matching the image interpretation data. Finally, the electronic device invokes an application (e.g., a computer game) associated with the prestored target object (e.g., a virtual character of the computer game) and renders, using the application, the prestored target object on the display screen.
