Outdoor construction method based on UAV photography technology and bim technology

Abstract

The present invention discloses an outdoor construction method based on a UAV photography technology and a BIM technology. The method comprises the following steps: 1) acquiring UAV field data; 2) performing data processing by using corresponding software; 3) establishing a BIM information model; 4) by applying a BIM technology, performing sloping according to different sites and designs; and 5) designing a BIM site model. The method disclosed by the present invention has the following advantages: manpower cost and time cost of measurement are greatly reduced; on-site terrain data is acquired in real time, which is convenient and quick; by combining BIM, on-site construction is provided with a visualized three-dimensional model and precise data at each stage, such as excavation volume reports, construction drawings and spatial information, so as to ensure implementation of project quality.

Description

technical field [0001] The invention relates to the field of earthwork measurement and construction technology, in particular to an outdoor construction method based on unmanned aerial vehicle photography technology and BIM technology, which is suitable for construction land with fewer buildings and a wider site, and for large-scale infrastructure projects, road and bridge projects should be applicable. Background technique [0002] In large-scale and large-scale infrastructure projects, the outdoor project will undoubtedly look at the entire site and play a decisive role in the image of the project. Therefore, in order to reasonably arrange the project progress, accurately calculate the project cost, and improve the project quality, it is usually necessary to be efficient, Accurately calculate site earthwork volume. The quality and efficiency of earthwork measurement will bear a large weight in the project, which directly affects the cost and progress of the project, and a...

Problems solved by technology

[0011] However, in the above calculation methods, there are still the following defects: the earthwork survey of the grid method requires the measurement of the elevation of the grid nodes, which requires the grid layout in advance, and then measures the node elevation, which greatly increases the workload; The measurement workload of the section method to calculate the earthwork is generally large, and its accuracy is related to the distance between sections and the selection of elevation points on the section.

It is not applicable to the tight construction period and large volume measurement
