Browser Display Verification for Web Map Rendering Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The correctness of Web maps drawn and displayed in browsers cannot be verified due to variations in browsers, systems, and graphics hardware, making it difficult to ensure accurate map rendering.
Innovation Solution
A display verification method and apparatus that provides image drawing data to the browser for local rendering, acquires the rendered image, and compares it with a standard image to detect any display abnormalities, with the option to switch to server rendering if issues are found.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If browser local rendering is used for Web maps, then rendering speed and user experience are improved, but rendering correctness and consistency cannot be guaranteed
Solution Approach 1:
The patent implements a feedback mechanism where the rendered map image from the browser is captured and sent back to the server for verification. The server compares the browser-rendered image with a standard reference image to detect any rendering discrepancies. This feedback loop enables the system to identify rendering errors and trigger corrective actions while maintaining the performance benefits of client-side rendering.
Solution Approach 2:
The server acts as an intermediary between the browser and the standard map rendering system. It receives the browser-rendered image, performs verification against the standard image, and can provide correction guidance or fallback rendering. This intermediary role allows the system to maintain both client-side rendering performance and server-side rendering quality control.
2Productivity
If browser local rendering is used, then system resource utilization is improved, but verification of rendering accuracy becomes difficult
Solution Approach 1:
The patent uses image copying technology to capture the browser-rendered map display and create a digital copy of the rendered image. This copy can then be transmitted to the server for automated comparison with the standard reference image. The copying approach enables automated verification without requiring manual visual inspection, significantly reducing verification difficulty while maintaining efficient resource utilization.
3Reliability
If rendering verification is implemented, then rendering correctness is improved, but system complexity increases
Solution Approach 1:
The patent implements a universal verification mechanism that works across different browsers and operating systems by capturing the rendered image output and comparing it with a standard reference. The verification system is designed to be browser-agnostic and platform-independent, using standard image processing and comparison techniques that can be applied universally. This approach maintains rendering correctness across diverse environments without requiring separate verification systems for each platform.
