Engineering Contradiction Analysis
1Productivity
If traditional map board pattern and separated management of engineering geological data according to projects are used, then data management is simple, but construction efficiency is reduced
Solution Approach 1:
The patent merges multiple geological image graphs into a single comprehensive geological information management system. By integrating vector data and image data through spatial-location matching, the system combines previously separated data management approaches into a unified platform that improves construction efficiency while maintaining manageable complexity through systematic organization.
2Area of stationary object
If multiple geological image graphs are joined together to form large-scale ground images, then comprehensive geological coverage is improved, but processing complexity increases
Solution Approach 1:
The patent segments the process of creating large-scale ground images into distinct steps: acquiring multiple geological image graphs, determining coordinate relations through imaging mode analysis, performing geometric correction on individual graphs, and finally joining them according to optimal mosaic borders. This segmentation manages processing complexity by breaking down the complex task into manageable stages while achieving comprehensive ground coverage.
Solution Approach 2:
The patent performs preliminary geometric correction and coordinate system transformation on individual geological image graphs before joining them together. By pre-processing each image graph to establish accurate image coordinate to ground coordinate relations, the system simplifies the subsequent joining process and ensures high-quality large-scale ground images with reduced overall processing complexity.
3Manufacturing precision
If geometric correction and optimal mosaic border determination are performed, then image joining precision is improved, but processing time increases
Solution Approach 1:
The patent implements self-service mechanisms in the image processing workflow through automated optimal mosaic border determination. The system automatically identifies and determines the best mosaic borders by analyzing brightness continuity and geometric relationships, eliminating the need for manual intervention while maintaining high joining precision. This automation reduces processing time compared to manual methods while preserving accuracy.
