Abstract: Disclosed are a method, an apparatus and a storage medium for measuring the quality of a built environment. The method includes the following steps: identifying key influencing factors determining environmental quality, and establishing an index system of environmental quality influencing factors, wherein the key influencing factors include non-observation elements and observation elements; analyzing the relationship between the environmental quality and the key influencing factors to form a theoretical model; acquiring observation elements to form a large sample database; calculating path coefficients of each key influencing factor of environmental quality according to the distribution of sample data in the large sample database, and converting the path coefficients into weights; dividing distribution intervals of all observation elements dynamically according to the distribution of sample data, and defining quality assignments of all observation elements; and performing an environmental quality measurement of samples in combination with the weights and the quality assignments.

Abstract: The present invention discloses an artificial intelligence (AI)-based method for generating a building block in a commercial district, and relates to the field of AI urban design. According to the present invention, geographic information data of a target district and surrounding districts is acquired to construct a three-dimensional space sand table, then design conditions in various planning files and local legal regulations are translated and extracted to generate a three-dimensional building block of the district, and then a training sample library of three-dimensional contour lines of the district is constructed, a machine learning model is loaded to generate three-dimensional building heights of the district and optimize building forms, to generate a plurality of schemes for the building block of the district, and finally simulated display of the schemes and display of scheme indexes are performed by using a holographic display device, and the schemes are outputted. For the problem that a previous generation of AI technology generates a large quantity of invalid schemes, the present invention realizes the AI-based generation of a plurality of valid schemes, resolving the problem that the previous generation of AI requires a long time and large manpower to screen out a valid scheme, and improving the design efficiency for planners.

Abstract: 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.
