Problems solved by technology

[0002] In the home design industry, designers need all the detailed information of the house structure and the geometric dimensions of the house, and the process of obtaining all the detailed information of the house structure and the geometric dimensions of the house is complicated, requiring professional surveyors to conduct multi-point measurements on the spot and record each In most cases, the location information of the measurement point needs to be measured by the designer on the spot, and the on-site measurement takes up a lot of time for the designer, which not only costs a lot of time, but also leads to a lot of wasted labor costs

Embodiment 1

[0064] An example of this application, such as figure 1 As shown, a house structure analysis method is proposed, the method includes:

[0065] S100: Obtain a building point cloud.

[0066] The low-cost iPad pro (no technical threshold requirement for users) can be used to scan the house in 3D to obtain the house point cloud in real time. The house point cloud obtained by the iPad pro can also be stored in a predetermined database, and when a certain house structure needs to be analyzed, the house point cloud corresponding to the house can be obtained from the database.

[0067] S200: Determine, according to the coordinates of the house point cloud, the number of floors of the house formed by the house point cloud and the sub-house point cloud corresponding to each floor of the house.

[0068] It can be understood that the Z coordinate of the house point cloud is the coordinate in the height direction. When the height of the point cloud is higher, the corresponding Z coordina...

Embodiment 2

[0082] An example of this application, such as image 3 As shown, a method for determining the wall point cloud of the i-th layer by using the remaining point cloud after removing the roof point cloud of the i-th layer and the ground point cloud of the i-th layer is proposed, the method includes the following steps :

[0083] S341: Vertically project the three-dimensional structure formed by the remaining point clouds of the i-th layer onto the two-dimensional plane bird's-eye view.

[0084] S342: Perform denoising processing on the remaining point cloud based on the two-dimensional image on the two-dimensional plane bird's-eye view to determine the wall point cloud of the i-th layer.

[0085] It can be understood that the three-dimensional structure formed by the remaining point cloud of the i-th layer includes the walls of the house. According to prior knowledge: the walls of the house and the walls of the adjacent houses are basically perpendicular to each other, and it ca...

Embodiment 3

[0102] An example of this application, such as Figure 6 As shown, a house structure analysis method also includes the following steps:

[0103] S500: Fit each group of sub-wall point clouds of the i-th layer based on a predetermined second fitting accuracy, where the second fitting accuracy is greater than the first fitting accuracy.

[0104] S600: Vertically project the fitted sub-walls formed by each group of sub-wall point clouds of the i-th layer onto the two-dimensional plane bird's-eye view to determine whether there are concave-convex parts on the corresponding sub-walls.

[0105] S700: If there is a concave-convex part, determine the thickness of the concave-convex part on the bird's-eye view of the two-dimensional plane.

[0106] S800: Project each group of sub-wall point clouds of the fitted i-th layer onto the corresponding XZ plane or YZ plane to determine the height and width of the concave-convex part of the corresponding sub-wall.

[0107] S900: Determine whe...

Abstract

The embodiment of the invention discloses a house structure analysis method and device, terminal equipment and a readable storage medium. The method comprises the steps: acquiring a house point cloud, determining the number of floors of a house formed by the house point cloud and a sub-house point cloud corresponding to each floor of the house according to the coordinates of the house point cloud, dividing the sub-house point cloud corresponding to each floor into wall point clouds, roof point clouds and ground point clouds according to the coordinates of the sub-house point cloud corresponding to each floor, and determining the number of sub-walls of each layer, the sub-wall point cloud corresponding to each sub-wall of each layer, the number of rooms of each layer and the room point cloud corresponding to each room of each layer according to the wall point cloud of each layer. The method realizes automatic analysis of the house structure based on the house point cloud, does not need field measurement by professionals, and avoids waste of excessive time cost in field measurement.

Description

technical field [0001] The present invention relates to the field of point cloud image processing, in particular to a house structure analysis method, device, terminal equipment and readable storage medium. Background technique [0002] In the home design industry, designers need all the detailed information of the house structure and the geometric dimensions of the house, and the process of obtaining all the detailed information of the house structure and the geometric dimensions of the house is complicated, requiring professional surveyors to conduct multi-point measurements on the spot and record each In most cases, the position information of the measurement points requires the designer to measure on the spot, and the on-site measurement takes up a lot of time for the designer, which not only costs a lot of time, but also leads to a lot of wasted labor costs. Contents of the invention [0003] In view of the above problems, the present invention proposes a house struct...
