Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current scanners and detectors are limited in their ability to scan small or multiple QR codes and barcodes from screens or images, requiring significant space and manual processing, and cannot read multiple elements simultaneously.
Innovation Solution
A system that enables computerized devices to scan screens directly, using various triggers to capture and process screenshots or focus on specific areas, allowing for the scanning of multiple QR codes or barcodes with reduced size and detail requirements, and performing processes based on scanning results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional scanners are used to scan QR codes from screens, then the QR codes must be large in size to be scannable, but this blocks parts of the media and reduces screen efficiency
Solution Approach 1:
The patent changes the scanning parameters by using camera-based detection with image processing algorithms that can识别 QR codes at much smaller sizes than traditional optical scanners. The system captures screen content via camera, processes the image digitally, and detects QR codes regardless of their small dimensions, thus enabling scanning of compact codes without blocking media content.
Solution Approach 2:
The patent replaces the mechanical optical scanning system with a camera-based imaging system combined with digital image processing. Instead of using a physical scanner that requires direct contact and large code size, the system uses a camera to capture the screen and software algorithms to detect and decode QR codes, enabling detection of much smaller codes.
2Measurement precision
If traditional scanners are used to scan multiple QR codes, then only one code can be scanned at a time, but this reduces scanning efficiency and productivity
Solution Approach 1:
The patent performs preliminary capture of the entire screen content in a single camera frame, which contains multiple QR codes simultaneously. The image processing system then processes this single captured image to detect and decode all QR codes present in the frame, eliminating the need for sequential scanning and significantly improving productivity.
Solution Approach 2:
The patent merges multiple QR code detection operations into a single image processing operation. By capturing all codes in one screen shot and processing them together through image analysis algorithms, the system achieves parallel detection of multiple codes, enhancing scanning speed and efficiency.
3Measurement precision
If manual processing is used to prepare screenshots for scanning, then the process becomes complex and time-consuming, but this reduces ease of operation
Solution Approach 1:
The patent implements self-service by automatically capturing the screen content, processing the image, detecting QR codes, and presenting results without requiring user intervention for cropping, focusing, or manual preparation. The system autonomously performs all necessary operations from screen capture to code detection and result display.
Solution Approach 2:
The system performs preliminary automatic screen capture and image processing before the user needs to view results. By pre-capturing the screen content and pre-processing the image for optimal detection, the system eliminates the need for manual screenshot preparation and directly presents scanning results to the user.
