and firstly, carrying out point cloud data segmentation on the three-dimensional point cloud data to obtain a three-dimensional point cloud sub-data sequence.
In practice, the executing body can perform point cloud data segmentation on the three-dimensional point cloud data through a clustering algorithm to obtain a three-dimensional point cloud sub-data sequence. Specifically, the clustering algorithm may be a K-means clustering algorithm. In addition, the execution body may further perform point cloud data segmentation on the three-dimensional point cloud data based on a segmentation manner of geometric features (e.g., based on curvature, curvature change rate, etc.), to obtain a three-dimensional point cloud sub-data sequence.
Second, for each three-dimensional point cloud sub-data in the three-dimensional point cloud sub-data sequence, executing the following processing steps:
And a first sub-step of performing unit face segmentation on the three-dimensional point cloud sub-data to generate three-dimensional point cloud data blocks and obtain a three-dimensional point cloud data block set.
Wherein, the unit surface is a region with preset size. In practice, the execution body may perform unit surface segmentation along a plane formed by the three-dimensional point cloud sub-data, so as to generate a three-dimensional point cloud data block, and obtain a three-dimensional point cloud data block set. The three-dimensional point cloud data block is composed of at least one three-dimensional coordinate point in a unit area surrounding the city.
And a second sub-step of performing outlier rejection on each three-dimensional point cloud data block in the three-dimensional point cloud data block set to generate an outlier-rejected three-dimensional point cloud data block, and obtaining an outlier-rejected three-dimensional point cloud data block set.
Wherein, first, the execution body may determine a midpoint coordinate of at least one three-dimensional coordinate point included in the three-dimensional point cloud data block. And then, determining the coordinate distance between at least one three-dimensional coordinate point included in the three-dimensional point cloud data block and the midpoint coordinate, and sequencing the at least one three-dimensional coordinate point included in the three-dimensional point cloud data block according to the coordinate distance. Then, the execution subject may reject the last K three-dimensional coordinate points out of the sorted at least one three-dimensional coordinate point as outliers. The value of K may be determined according to the number of three-dimensional coordinate points in at least one three-dimensional coordinate point included in the three-dimensional point cloud data block. For example, k=10% ×m. M is the number of three-dimensional coordinate points in at least one three-dimensional coordinate point included in the three-dimensional point cloud data block. K is more than or equal to 0, and when 10 percent of the X M exists in decimal, the value of the 10 percent of the X M is rounded downwards.
And a third sub-step of determining the surface center of the unit surface corresponding to each outlier-removed three-dimensional point cloud data block in the outlier-removed three-dimensional point cloud data block set to obtain a surface center set.
In practice, the surface center may be a position point corresponding to a midpoint coordinate of at least one three-dimensional coordinate point included in the three-dimensional point cloud data block after the outlier is removed.

The content of the foregoing "in some alternative implementations of some embodiments" is taken as an invention point of the disclosure, which solves the second technical problem mentioned in the background art, namely, "the conventional three-dimensional modeling manner occupies relatively much computing resources, and increases the computing resource occupancy rate of the three-dimensional modeling simulation. Based on this, the present disclosure simplifies the way of construction when constructing a three-dimensional model, i.e., only three-dimensional construction of the three-dimensional model surface is considered. Specifically, first, point cloud data is divided into point cloud data, so that synchronous processing can be performed on a plurality of three-dimensional point cloud sub-data in parallel. Next, since the present disclosure relates to only three-dimensional construction of a surface of a three-dimensional model, unit face segmentation is performed on the three-dimensional point cloud sub-data to generate a three-dimensional point cloud data block, and a three-dimensional point cloud data block set is obtained. Compared with the voxelization mode, the data processing amount is reduced. And then, performing outlier rejection on each three-dimensional point cloud data block in the three-dimensional point cloud data block set to generate an outlier-rejected three-dimensional point cloud data block, and obtaining an outlier-rejected three-dimensional point cloud data block set. To reduce the effect of outliers on the final modeled longitude.

And the three-dimensional point cloud data blocks after the elimination in the unit surface are represented by the surface center, so that the volume of the point cloud data for modeling is further reduced. And finally, carrying out plane construction according to the obtained plane center set to generate an initial plane corresponding to the three-dimensional point cloud sub-data. By the method, the processing amount of three-dimensional modeling data is reduced, and the occupation of resources is reduced.

In some embodiments, the executing body may determine the water inlet point information in the target power distribution room according to the three-dimensional model, so as to obtain a water inlet point information set. The water inlet point information characterizes an area communicated with the outside in the three-dimensional model. In other words, the water inlet point information may also characterize the area in the target distribution room that communicates with the outside world. Optionally, the water inlet point information in the water inlet point information set may include: the position of the water inlet point and the specification of the water inlet point. The water inlet point position represents coordinates of the water inlet point in the three-dimensional model, and can also represent three-dimensional coordinates in a target power distribution room. The coordinates of the water inlet points, which are characterized by the positions of the water inlet points, in the three-dimensional model and the three-dimensional coordinates, which are characterized by the positions of the water inlet points, in the target distribution room can be mutually converted. In practice, the execution subject may determine the position of the water inlet point by calculating the slope of the plane of the three-dimensional model, and determining the position of the area where the slope disappears or the position where the peripheral slope value is larger than the own slope value. The influent point specification characterizes the area size of the influent point.
In some optional implementations of some embodiments, the executing body determines, according to the three-dimensional model, water inlet point information in the target power distribution room to obtain a water inlet point information set, and may include the following steps:
and a first step of determining a plane boundary according to the plane construction information of the distribution room.

In practice, the execution body may generate a distribution room plan for the target distribution room based on the distribution room plan configuration information. In particular, the executive body may import the panelist plane configuration information into engineering drawing software, such as CAD (Computer AIDED DESIGN) software, to generate the panelist plane map. The execution subject may then determine a house plane boundary of the target distribution room in a distribution room plan as the plane boundary.
And a second step of determining a local three-dimensional model matched with the plane boundary in the three-dimensional model.
The boundary similarity between the orthographic projection boundary corresponding to the local three-dimensional model and the plane boundary meets a preset similarity condition. In practice, first, the execution subject may split the three-dimensional model into a plurality of candidate local three-dimensional models. Wherein the orthographic projection boundary of the candidate local three-dimensional model is a closed boundary. Then, the execution body may determine a boundary similarity between an orthographic projection boundary of each of the plurality of candidate local three-dimensional models and the plane boundary, respectively. Then, the execution subject may screen out the candidate local three-dimensional model with the corresponding boundary similarity as the maximum value from the candidate local three-dimensional models as the local three-dimensional model.
And thirdly, determining a concave area corresponding to the local three-dimensional model to obtain a concave area set.
Wherein the curvature value of each point in the concave area is a positive value. In practice, the execution body can determine the concave area corresponding to the local three-dimensional model by calculating the curvature of the curved surface to obtain a concave area set.
And step four, determining the area position of each concave area in the concave area set in the three-dimensional model as the water inlet point position included in the water inlet point information corresponding to the concave area in the water inlet point information set.
And fifthly, determining the area size of each concave area in the concave area set as the water inlet point specification included in the water inlet point information corresponding to the concave area in the water inlet point information set.
And 105, carrying out information matching on the water inlet point position information in the water inlet point position information set to generate simulated water inlet point position information, and obtaining a simulated water inlet point position information set.
In some embodiments, the executing body may perform information matching on the water inlet point information in the water inlet point information set to generate simulated water inlet point information, so as to obtain a simulated water inlet point information set. The simulated water inlet point position information in the simulated water inlet point position information set comprises: at least one water inlet point position information. And when the flooding simulation is carried out, taking the position corresponding to the position information of at least one water inlet point included in the simulation water inlet point position information characterization as the water inlet point.
In some optional implementations of some embodiments, the performing body performs information matching on the water inlet point location information in the water inlet point location information set to generate simulated water inlet point location information, to obtain a simulated water inlet point location information set, and may include the following steps:
The first step is to determine the number of the water inlet point location information in the water inlet point location information set as a first target value.
In practice, the execution body may determine the first target value through a len () function.
And a second step of generating a range of intervals by taking the first target value as an upper interval and taking the second target value as a lower interval.
Wherein the second target value is 1.
And thirdly, carrying out random non-repeated combination on the water inlet point position information in the water inlet point position information set by taking the interval value as a quantity constraint value for each interval value in the interval range to obtain the simulated water inlet point position information in the simulated water inlet point position information set.
Wherein the interval value is an integer value.
As an example, the interval range may be [1,3]. The set of water intake point location information may include: water inlet point information a, water inlet point information B, water inlet point information C, water inlet point information D, water inlet point information E, and water inlet point information F.

The above embodiments of the present disclosure have the following advantageous effects: the flooding simulation method applied to the distribution room reduces the risk of the equipment being damaged by flooding through some embodiments of the present disclosure. In particular, the higher risk of flooding damage to the equipment is due to: the timeliness of manual inspection is poor, and flooding protection is extremely easy to be untimely, so that the risk of equipment being damaged by flooding is increased. In practice, when the flooding condition is complex, the mode of adopting manual inspection and carrying out flooding protection according to the actual condition is poor in timeliness, and because water has conductivity, the untimely flooding protection is extremely easy to increase the short circuit risk of equipment, so that the risk of equipment flooding damage is increased. Based on this, a flooding simulation method applied to a distribution room according to some embodiments of the present disclosure first obtains distribution room description information corresponding to a target distribution room, where the distribution room description information includes: the system comprises distribution room plane configuration information and distribution room equipment information, wherein the distribution room plane configuration information is used for describing the house plane configuration of the target distribution room, and the distribution room equipment information is used for describing equipment parameters and equipment layout of distribution room equipment in the target distribution room. Thus, the house plane structure and the equipment layout corresponding to the target distribution room are obtained. And secondly, determining three-dimensional point cloud data aiming at the target distribution room according to the distribution room description information. Then, a three-dimensional model for the target distribution room is generated based on the three-dimensional point cloud data. Thus, a three-dimensional model for the target distribution room is obtained for subsequent flooding simulation. Further, according to the three-dimensional model, water inlet point information in the target power distribution room is determined, and a water inlet point information set is obtained. In practice, there are often multiple areas of the target distribution room that are in communication with the outside, and when flooding occurs, the areas that are in communication with the outside may be water intake locations. In addition, the information matching is carried out on the water inlet point position information in the water inlet point position information set so as to generate simulated water inlet point position information and obtain a simulated water inlet point position information set. In practice, there may be a case where water is simultaneously fed from a plurality of water feeding positions, and thus, a combination of water feeding points is required.
