Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual field survey method is used for landscape evaluation, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The patent replaces manual field survey methods with automated computer-based image analysis technology. Street view pictures are automatically captured and processed through AI image recognition algorithms to identify landscape elements and calculate viewing areas, eliminating subjective human evaluation while maintaining operational simplicity.
Solution Approach 2:
The patent uses street view pictures as digital copies of the urban landscape to perform analysis. These image copies contain sufficient visual information to identify mountains, water, architecture, and other landscape elements, allowing precise measurement without requiring physical field surveys.
2Measurement precision
If computer viewing image analysis based on street view pictures is used, then measurement precision is improved, but interactivity deteriorates
Solution Approach 1:
The patent transforms the static street view image analysis into a dynamic interactive system. Users can input different planning schemes, and the system dynamically recalculates and displays the viewing corridor analysis results in real-time, enabling interactive exploration of different urban planning scenarios.
Solution Approach 2:
The patent implements a feedback mechanism where the system not only analyzes current viewing corridors but also provides optimized responses for planning schemes. The analysis results feed back into the planning process, allowing iterative improvement of urban design based on quantitative viewing corridor metrics.
3Measurement precision
If GIS view field analysis based on digital modeling is used, then measurement precision is improved, but authenticity deteriorates
Solution Approach 1:
The patent uses actual street view pictures captured from the urban environment as the basis for analysis, rather than relying on idealized digital models. These real photograph copies preserve the authentic visual characteristics, lighting conditions, and actual landscape elements present in the urban space.
Solution Approach 2:
The patent focuses analysis on specific local viewing points and directions captured in street view pictures. By analyzing each location's actual visual characteristics rather than applying uniform digital modeling assumptions, the method preserves the local authenticity of different urban landscapes including variations in architecture, terrain, and vegetation.

AI summary
The present invention discloses a dynamic interactive simulation method for recognition and planning of an urban viewing corridor. The method includes: constructing a sand table of morphology data of an urban space around an urban viewing point; creating a visual sphere, calculating a blocking point set, acquiring a three-dimensional view field of the viewing point, and obtaining an effective projection plane of a sight line of the viewing point; extracting a visual three-dimensional road model, calculating projection curvatures of road centerlines at points equidistant from each other, and screening and recognizing a viewing corridor; collecting a real scene, and inputting the collected real scene to a three-dimensional interactive display platform; inputting a new planning scheme to the three-dimensional interactive display platform, and simulating an urban viewing corridor with the planning scheme superimposed; and outputting, by using augmented reality glasses, a dynamic interactive VR scene of the urban viewing corridor space after the urban planning scheme is superimposed. The present invention combines a real dynamic viewing process, and uses a three-dimensional interactive display platform for planning simulation and interactive output, thereby providing a basic rational support for further optimization and decision-making of urban planning and design.
