Embodiment Construction

[0043] The present invention is further described in conjunction with the following examples.

[0044] The method for constructing scene based on BIM technology in this embodiment, such as figure 1 shown, including the following steps:

[0045] Step 1: Photographic photo data processing: Obtain a group of site photos from multiple angles, import the photos into Agisoft Metashape Pro software for processing, and the software extracts image information and converts them into point clouds;

[0046] Step 2: Cloud editing, classification and automatic calibration: Edit and arrange the generated point cloud data, classify the point information and reconstruct the geometry, and the saved file format is .LAS;

[0047] Step 3: Generate DSM / DTM: Generate DSM (Digital Surface) / DTM (Digital Terrain) model based on projection calculation;

[0048] Step 4: Correct the texture color of the DSM (Digital Surface) / DTM (Digital Terrain) model;

[0049] Step 5: Export the model to .obj format;...

Abstract

The invention discloses a BIM (Building Information Modeling) technology-based scene construction method, which relates to the technical field of garden landscape model manufacturing, and comprises the following steps of obtaining a group of site photos at multiple angles, importing the photos into Agisoft Metaphapp Pro software for processing, extracting image information by the software, and converting the image information into point cloud; editing and arranging the generated point cloud data, classifying the point information and geometrically reconstructing the point information, and storing the point cloud data in a file format of. LAS; generating a DSM/DTM model according to projection calculation; correcting the texture color of the DSM/DTM model; exporting the model into a. Obj format; importing the model in the. Obj format into 3D software for processing. According to the method for exporting the model in the SU format from the 3D software, the two kinds of software, namely the Agisoft Metaphapp Pro and the 3D software, are reasonably applied, organic combination of the two kinds of software is achieved, the advantages are complementary, and then manufacturing of a realistic site is achieved.

Description

technical field [0001] The invention relates to the technical field of garden landscape model making, in particular to a BIM technology-based scene construction method and system and its application in garden landscape digital modeling. Background technique [0002] With the continuous development of BIM (Building Information Modeling) in the construction industry at home and abroad, the application of BIM in landscape architecture has been paid more and more attention. Site model is an important part of landscape architecture. [0003] The site model modeling is divided into five types according to the type of site primitives: site terrain, road square, parking lot, green water body, and building structure. In the existing technology, it is difficult for the site terrain model to realistically reflect the real ups and downs. Contents of the invention [0004] The purpose of the present invention is to avoid the deficiencies in the prior art and provide a scene constructi...
