Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video monitoring is used for scene monitoring, then warning can be provided in advance on some dangers, but the monitoring is merely locally visible and does not provide real-time real situation reproduction
Solution Approach 1:
The patent transitions from traditional 2D video monitoring to 3D panoramic visualization. Multiple panoramic cameras capture images from different positions, and through splicing and geometric correction, construct a three-dimensional real-geographic-space scene. This dimensional enhancement provides comprehensive situational awareness while maintaining real-time monitoring capabilities.
Solution Approach 2:
The patent combines multiple panoramic cameras, attitude sensors, measuring robots, and audio collecting devices into an integrated monitoring system. These components work together to collect, process, and synthesize multi-source data, merging visual, spatial, and auditory information into a unified three-dimensional scene representation.
2Device complexity
If video monitoring does not perform geometric correction and image splicing, then the system is simple, but deformation increases at higher observation distances
Solution Approach 1:
The patent performs geometric correction and orthographic projection in advance during the image processing stage. By pre-calculating and applying correction parameters based on camera positions and attitudes, the system eliminates deformation issues before presentation, ensuring accurate spatial representation without adding real-time processing complexity.
Solution Approach 2:
The patent introduces intermediate processing steps including splicing stitching modules and geometric correction modules that act as mediators between raw panoramic images and the final three-dimensional scene. These intermediary components handle the complex transformations, isolating the complexity from the main monitoring function.
3Device complexity
If video monitoring does not form a real visualized video scene with three-dimensional geographic coordinates, then the system is simple, but the actual production process cannot be accurately analyzed and controlled
Solution Approach 1:
The patent enhances traditional 2D monitoring by constructing a three-dimensional real-geographic-space scene with accurate geographic coordinates. This dimensional enhancement enables precise spatial analysis, volume measurement, and positional tracking, providing the measurement precision required for accurate production process analysis and control.
4Loss of information
If panoramic cameras are used to construct real-geographic-space scene, then real-time three-dimensional visualization is achieved, but the system complexity increases
Solution Approach 1:
The patent divides the complex monitoring system into modular functional components: panoramic camera modules, attitude sensor modules, measuring robot modules, audio collecting devices, and centralized processing modules. Each module performs a specific function, and the modular architecture simplifies system management, maintenance, and scalability while achieving comprehensive three-dimensional visualization.
