Embodiment Construction
[0026] Such as figure 1 As shown, this embodiment is a reverse three-dimensional modeling method of an established hydropower station, and the specific steps are as follows:
[0027] Familiarize yourself with the layout and geographical environment of the built hydropower station first, select a 3D laser scanner that meets the accuracy requirements according to the needs, design the scanning site and scanning path of the 3D laser scanner, and use the 3D laser scanner to analyze the building structure and equipment of the built hydropower station. The site collects data and obtains point cloud data of the building structure and equipment of the hydropower station;
[0028] Perform denoising processing on the obtained initial point cloud data, check whether the point cloud data is correct with the on-site photos and drawings, and store it for backup after the check is completed; combine the on-site photos and drawings to point cloud data after denoising processing The splicing ...

The invention relates to a built hydropower station reverse three-dimensional modeling method and device, a storage medium and equipment, provide a reverse three-dimensional modeling method and devicefor a built hydropower station, a storage medium and equipment so as to quickly, efficiently and accurately carry out three-dimensional digital modeling on the built hydropower station. According tothe technical scheme, the built hydropower station reverse three-dimensional modeling method is characterized by comprising the steps of acquiring hydropower station building structure point cloud data and equipment point cloud data; de-noising the point cloud data of the hydropower station building structure and the point cloud data of the equipment, and splicing to form a point cloud data three-dimensional surface model of the hydropower station building structure and the equipment; and importing the point cloud data three-dimensional surface model of the hydropower station building structure and equipment into three-dimensional modeling software to create a fine model of the hydropower station building structure and equipment. The method is suitable for the field of power station modeling.
Description
technical field [0001] The invention relates to a reverse three-dimensional modeling method, device, storage medium and equipment of an established hydropower station. Applicable to the field of power station modeling. Background technique [0002] With the development of industrial technology, my country will carry out research and development of hydropower technology, equipment and ecological technology, and build "Internet +" smart hydropower stations. Intelligence will become the main development trend of hydropower station construction in the future. [0003] The foundation of intelligent hydropower station construction is power station digitization, and an important feature of power station digitization is the three-dimensional digitization of the physical power station. For the hydropower station that has been built for many years, due to technical limitations at the time of design, there was no 3D digital model, and after many technical transformations, the design d...
