Embodiment

[0035] Refer to attached figure 1 , this embodiment provides a method for site selection and design of a temporary construction project based on multi-source data fusion technology, the specific method is as follows:

[0036] 1) Multi-source data to build a 3D GIS model

[0037] Download the high-precision digital surface model (DSM) .tif format file and the moderate-resolution digital orthophoto image (DOM) .tif format file in the construction area through the network map software. Note: If the resolution is too high, the image memory will be quite large , it is prone to problems such as download failure and data loading freeze;

[0038] UAVs collect images on site, establish aerial survey data processing procedures in the office, and produce high-definition 1:1 digital orthophoto (DOM).tif format files;

[0039] Through the global mapper software, the boundaries of the UAV orthophoto data are cropped, and the above three digital products are geo-calibrated respectively;

Abstract

According to the temporary construction project site selection and design method based on the multi-source data fusion technology. Three-dimensional design is carried out on temporary construction project planning based on the geometric analysis function of the three-dimensional real terrain, fusion is carried out, and the temporary construction project site selection and design efficiency is improved. The method aims to overcome the defects of long time consumption, large field workload, low design efficiency and the like of traditional temporary construction engineering site selection and design, and belongs to the field of constructional engineering.

Description

technical field [0001] The invention relates to a site selection and design method for temporary construction projects based on multi-source data fusion technology, which is especially suitable for site selection and design of large temporary facilities for construction investigation of new projects, and belongs to the field of construction engineering. Background technique [0002] In the engineering construction industry, especially railway or highway engineering, in order to grasp the geospatial information of the construction site and be familiar with the geographical environment of the construction site in the project construction investigation, the current more advanced method is to load the line kml file on the OVC map, according to The automatic positioning of the mobile phone, the investigation team uniformly entered the site for on-site survey, and planned the construction location of the Dalin facility according to the site terrain. The field workload is quite huge...
