First claim

What is claimed is:

1 . An artificial intelligence (AI)-based urban design multi-plan generation method for a regulatory plot, the method comprising the following operation steps:
(a) collecting two-dimensional vector data of surrounding architectures and roads, verifying three-dimensional spatial information via an unmanned aerial vehicle (UAV) oblique photography, and generating a 3D model by stretching architectures based on storey quantities and forming roads based on centerline and width data; (b) scanning regulatory plan maps to obtain index data comprising land properties, entrance and exits locations, a development intensity, discount rates, and setback lines; and (c) inputting regulatory parameters and spatially linking to the 3D model; (d) acquiring an urban design case database, extracting a characteristic index system, and selecting similar cases via a decision tree; (e) generating road network plans by:
(i) forming a hidden grid between entrances and exits,
(ii) connecting shortest paths iteratively,
(iii) widening roads to comply with urban branch road specifications; and
(iv) verifying compliance with regulatory codes, and
(v) generating parameters for road network density, uniformity, accessibility, and connectivity, and
(f) generating landscape system plans by:
(i) setting a starting point in non-residential blocks,
(ii) configuring a basic unit with predefined open angle range α and length range li;
(iii) growing units via an L-System evolutionary algorithm until connectivity is achieved;
(iv) verifying separation from vehicle roads, and
(v) generating parameters for block quantity, area, and shape index;
(g) generating architectural combination plans by:
(i) constructing a sample database via vectorization;
(ii) matching cases with ≥90% similarity to select samples;
(iii) training a CVAE-GAN model to generate combinations;
(iv) verifying compliance with regulatory parameters and sunshine spacing;
(v) generating parameters for skyline profile volatility; and
(h) merging plans, into GIS layers, generating a report, and simulating scenes via virtual reality glasses.

2 . The method of claim 1 , wherein the hidden grid in step (e)(i) has a size of 30 m×30 m.
