Method for forming intuitive and visual data of concealed culvert structure detection

Abstract

The invention discloses a method for forming intuitive and visual data of concealed culvert structure detection, which comprises the following steps of: scanning the space appearance and the internal structure of a concealed culvert by using a three-dimensional laser scanning device to obtain a three-dimensional model of the concealed culvert; performing analyzing based on the three-dimensional model of the concealed culvert to obtain the size characteristics of a concealed culvert body, the spatial distribution condition of a concealed culvert inspection well and the troubleshooting and statistical information of a concealed culvert discharge port, so as to form intuitive visual data, wherein the troubleshooting and statistical information of the concealed culvert discharge outlet comprises the spatial position of the discharge outlet, the elevation of the pipe bottom, the diameter, the material and whether water flows out or not during actual measurement. According to the method, the three-dimensional laser scanning technology and the unmanned carrier are combined, detection of the buried culvert structure can be efficiently achieved, monitoring and analysis based on the three-dimensional model are more accurate, and visual and visual data can be rapidly obtained.

Description

technical field [0001] The invention relates to the technical field of implicit structure detection, in particular to a method for forming intuitive and visualized data for implicit structure detection. Background technique [0002] In some cities, the early drainage mode was mostly rainwater and sewage confluence, and the confluence pipe basically discharged into the box culvert. Because the discharge outlets of some pollution sources are relatively hidden, it is difficult to identify them by manual inspection. Although many places have completed the investigation and connection of pollution sources, the effect of new sewage pipes is still not obvious. In order to give full play to the role of sewage facilities and pipe network in sewage storage and operation as soon as possible, and to reduce the phenomenon of direct discharge of sewage into box culverts, it is often necessary to check and detect the internal drainage outlets and spatial structures of combined box culverts...

Problems solved by technology

[0002] In some cities, the early drainage mode was mostly the combined rain and sewage system, and the combined pipes were basically discharged into the box culvert. Because the discharge outlets of some pollution sources are relatively hidden, it is difficult to identify them by manual inspection.

Although many places have completed the investigation of pollution sources and connection work, the effect of new sewage pipes is still not obvious
