Problems solved by technology
The efficiency of the above-mentioned method is low, and there are large errors in manual measurement, and the accuracy is not high
[0004] Or, in some improved schemes, 3D modeling can be used to construct the 3D structural model of the building, but in these improved methods, the processing of data is not perfect, resulting in the accuracy of the constructed 3D structural model still to be determined. improve
[0005] At the same time, no matter in the two existing technologies, it is impossible to realize the matching display of decoration style information and building structure, and it is impossible to meet the needs of viewing building structure and decoration style at the same time

Embodiment Construction
[0028] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
[0029] figure 1 A flow chart of a method for generating a building model provided by an embodiment of the present invention is shown. This method can be applied to scenes that need to show the building structure and interior decoration style at the same time, so as to obtain a model that matches the structure and interior style. The method can be performed by any computing device with data processing capabilities. Such as figure 1 As shown, ...

The invention discloses a building model generation method and device, computing equipment and a storage medium. The method comprises the steps of obtaining an internal picture obtained through the photographing of the interior of a building, and obtaining point cloud data obtained through the scanning of the interior of the building by a scanner; registering the point cloud data and converting the point cloud data into a building coordinate system; in the building coordinate system, sectioning the selected sectioning plane for multiple times according to the point cloud data, and generating internal structure information of the building by utilizing the sectioned point cloud data; constructing a three-dimensional model of the building according to the internal structure information and the thickness information of the building; and performing mapping processing on the three-dimensional model according to the internal picture to generate a building model. According to the scheme, the point cloud data and the internal picture are combined, the building model containing the building structure and style can be constructed, and matching display of the building structure and the decoration style is facilitated.
Description
technical field [0001] The present invention relates to the technical field of the Internet, in particular to a method, device, computing device and storage medium for generating a building model. Background technique [0002] Buildings are one of the important places for people's daily life and activities, for example, living in houses, attending classes in teaching buildings, etc. At the same time, information such as the structure of the building and the interior decoration style needs to be checked in many occasions. [0003] In the prior art, information such as the size and position of each structure of the building is usually obtained through manual on-site measurement, and then the three-dimensional structural model of the building is obtained by drawing according to the measurement results. The efficiency of the above-mentioned method is low, and there are large errors in manual measurement, and the accuracy is not high. [0004] Or, in some improved schemes, 3D m...
