This utility model discloses a digital landscape model demonstration device, relating to the field of digital landscape model technology. It includes a housing with a top plate on top. A base is fixedly mounted on the top of the top plate, and a mounting frame is rotatably mounted on the upper end of the base. A digital landscape demonstrator is detachably mounted on the top of the mounting frame. A curved slide rail is symmetrically fixed to the top of the top plate with the base as the center. Support rods are symmetrically fixed to the side walls of the mounting frame. A T-shaped slide rod is fixedly mounted on the upper end of one support rod, limiting its sliding within the inner wall of one of the curved slide rails. A protruding rod is fixedly mounted on the upper end of the other support rod, sliding within the inner wall of the other curved slide rail. A locking bolt is threaded onto the end of the protruding rod away from the support rod, and the locking bolt movably fits against the side wall of the curved slide rail. Tightening the locking bolt ensures a tight fit against the side wall of the curved slide rail, allowing the device to be angled according to usage requirements, facilitating the demonstration of the landscape model.

This invention provides a drone VR landscape construction system based on spatial computing, comprising: a digital twin reference construction module for constructing a digital twin as an absolute spatial reference; a drone edge SLAM module for generating a sparse point cloud containing three-dimensional coordinates; a point-to-surface alignment correction module for continuously aligning the sparse point cloud to the surface of the digital twin using a point-to-surface matching algorithm to eliminate cumulative drift during drone operation; a virtual reality interaction module for displaying the reconstructed landscape scene from a first-person perspective and capturing the operator's gaze hotspots in real time; a dynamic re-collection feedback module for converting gaze hotspots into regions of interest and generating re-collection tasks to drive the drone to dynamically re-collect and verify the regions of interest; and an output module for generating a spatially computed, drift-free, and quality-labeled 3D VR landscape model. This invention aims to achieve drift-free, real-time human-machine collaborative high-fidelity VR landscape construction.

This application relates to the field of landscape design and digital modeling technology, and discloses a method and apparatus for establishing a landscape model based on data fusion technology. The method includes the following steps: collecting original point cloud data and images of the site; extracting key growth morphology parameters through data registration, semantic segmentation, and individual vegetation segmentation; constructing a multi-dimensional quantitative evaluation model of the landscape's ecology and aesthetics based on these parameters; transforming the design problem into a multi-objective optimization mathematical model and solving it to generate a Pareto optimal solution set; finally, converting the specific design scheme selected from the solution set into a parametric building information model and integrating it with a digital terrain model to generate an interactive three-dimensional integrated landscape model. This invention can objectively and efficiently generate optimized design schemes that take into account both ecological and aesthetic values, automating the design evaluation and optimization adjustment process, and improving the efficiency and optimization level of design scheme generation.
