Section diagram generation method, system and device and storage medium

Abstract

The invention discloses a cross-section diagram generation method and system, a computer device and a storage medium. The method comprises steps of obtaining aerial photography data through an unmanned plane, and carrying out the processing of the aerial photography data to obtain a digital elevation model, a topographic information image, a point element, point position coordinate information and elevation information, and generating a section diagram according to the corresponding relation between the point position coordinate information and the elevation information. The method is advantaged in that the unmanned aerial vehicle is used for collecting aerial photography data, image processing such as digital elevation model generation and terrain information image generation is carried out on the aerial photography data, information of areas where more people cannot reach can be collected, and measuring personnel can obtain section diagrams of more positions at a computer side in a man-machine interaction mode and the like; the method has high convenience, greatly reduces the operation intensity of measurement personnel, shortens the operation time, improves the operation efficiency, can assist the engineering construction, and effectively guarantees the work safety of the measurement personnel. The method is widely applied to the technical field of engineering data measurement.

Description

technical field [0001] The invention relates to the technical field of engineering data measurement, in particular to a method, system, computer device and storage medium for generating a section view. Background technique [0002] In the construction process of infrastructure and other engineering projects, it is necessary to obtain more accurate 3D terrain data as a basis for design and changes. In the existing technology, surveyors are required to carry total stations, GPS TRK measuring instruments and other instruments to carry out step-by-step surveys, and the construction areas that need to make cross-sectional diagrams are often complex in terrain, dense in vegetation, and vast in area, and there are many areas that are difficult for surveyors to reach. The method of manual surveying is intensive, inefficient, and data sampling is not comprehensive. It is difficult to obtain topographic data at any point or section, and it is not conducive to the work safety of survey...
