Technical Field

[0002] This section is intended to provide a background or context to embodiments of the invention that are recited in the claims. No description herein is admitted to be prior art by inclusion in this section.

[0003] At present, urban development needs to be planned and designed with the help of a three-dimensional planning and design system. In addition to the planning and design of buildings, the planning and design of green spaces and landscape trees are also indispensable for the planning and design of new residential areas.

[0055] Exemplary Methods

[0056] Reference below Figure 1 , Figure 1 This is a flow chart of a three-dimensional planning and design method for residential landscape provided by an embodiment of the present invention. It should be noted that the embodiments of the present invention can be applied to any applicable scenario.

[0057] Figure 1 The process of the three-dimensional planning and design method of residential landscape provided by an embodiment of the present invention includes:

[0058] Step S101, obtaining vector data of green space areas and geographical location information of the residential area from planning data of the residential area.

[0059] In an embodiment of the present invention, the geographical location information includes at least the longitude and latitude and altitude of the location of the residential area. The planning data may include at least a three-dimensional visualization model, a building surface, control planning data, land use data, and a road red line. Vector data of a green area may be obtained from the land use data. A three-dimensional planning model of a residential area may be established based on planning data, data such as the plot ratio and green area ratio of the residential area.

[0060] In the embodiment of the present invention, the vector data of the green area may be spatial data of the green area. The green area may be a polygonal area. The polygonal area may include multiple vertices. The vector data may include vertex coordinates of each vertex of the polygonal area.

[0062] In the embodiment of the present invention, the tree point coordinate set includes multiple tree point coordinates, and each of the tree point coordinates is located in the green area. The preset number of trees can be specified by the user, or the number of trees that can be planted in the current green area can be determined based on previous design experience, which is not limited in the embodiment of the present invention.

[0063] As an optional implementation, the green area is a polygonal area, and step S102 performs planning and design based on a preset number of trees and the vector data. The method of determining the tree point coordinate set of the green area may include the following steps:

[0064] Acquire multiple vertex coordinates of the green area from the vector data;

[0065] Projecting the vertex coordinates into a plane coordinate system to obtain plane green space area information; wherein the plane green space area information includes vertex plane coordinates corresponding to each vertex coordinate;

[0066] According to the preset number of trees and the plane green area information, a tree point coordinate set of the green area is determined; wherein each tree point coordinate included in the tree point coordinate set is located in the plane green area, and the plane green area is composed based on the plane coordinates of each vertex.

[0067] Among them, by implementing this implementation method, the green space area can be projected into the plane coordinate system according to the vertex coordinates in the vector data, and the plane green space area information corresponding to the green space area can be determined. Then, based on the obtained plane green space area information, the tree point coordinate set in the plane green space area can be determined, so that the tree point coordinate set can be determined more intuitively.

[0068] Optionally, according to the preset number of trees and the planar green area information, the method of determining the tree point coordinate set of the green area may include the following steps:

[0069] According to the vertex plane coordinates in the planar green space information, the area of ​​the planar green space area and the set of four points are calculated; wherein the set of four points includes a minimum horizontal coordinate, a minimum vertical coordinate, a maximum horizontal coordinate and a maximum vertical coordinate;

[0070] Calculate the tree spacing based on the preset number of trees and the area;

[0071] Based on the four-point set, determining a target area including the planar green space area;

[0072] Based on the preset number of trees, the tree spacing and the target area, a set of tree point coordinates in the green area is determined.

[0073] Among them, by implementing this implementation method, the area and the four-point set of the plane green space area can be calculated according to the vertex plane coordinates in the plane green space information, and then the tree spacing and the target area including the plane green space area can be calculated according to the obtained area and the four-point set. Therefore, the tree point coordinate set of the green space area can be determined according to the preset number of trees, tree spacing and target area, so that the obtained tree point coordinates are all located within the plane green space area, and the distances between each tree point coordinate are relatively balanced, thereby improving the rationality of the tree point coordinates.

[0074] In the embodiment of the present invention, the set of four points may include the minimum horizontal coordinate x min , minimum ordinate y min , maximum horizontal coordinate x max and the maximum ordinate y max The target area can be a rectangular area, and the four vertices of the target area can be: (x min ,y min )、(x min ,y max )、(x max ,y min ) and (x max ,y max ).

[0075] Specifically, according to the preset number of trees and the area, the formula for calculating the tree spacing is:

[0076]

[0077] Where S represents the area, n d Indicates the preset number of trees, and l indicates the distance between trees.

[0078] Optionally, based on the preset number of trees, the tree spacing and the target area, determining the tree point coordinate set of the green area may include the following steps:

[0079] 1) Set the tree spacing 1 and the number of tree points n p The set L(l i ,n pi), where l i ,n pi are a set of tree spacings and the number of tree points in the set, respectively;

[0080] 2) Set the row number to n. Initially, n = 0 and the tree point position is p. i (x i ,y i ), where y i =y min , establish the tree point coordinate set P, which is initially an empty set;

[0081] 3) If n is an even number, then is the horizontal coordinate of the first tree point in row n, that is, the first tree point p in row n i The coordinates of

[0082] If n is an odd number, then x i =x min is the horizontal coordinate of the first tree point in row n, that is, the first tree point p in row n i The coordinates of (x min ,y min );

[0083] After i =y min , and x i by The step size is increased multiple times, that is x i ∈[x min ,x max ];

[0084] Add each tree point coordinate that meets the above conditions into the tree point coordinate set P;

[0085] 4) When x i >x max When i Increase Right now n=n+1;

[0086] 5) If y i ∈[y min ,y max ], then execute step 3) to step 5);

[0087] 6) If Then get the number of tree points n in the tree point coordinate set P p ;

[0088] 7) If n p =0, then And execute step 2) to step 6);

[0089] 8) If n p ≠n d , then the set L(l i ,n pi ) is added to the set L, and L is adjusted by n pi Ascending, l i Sort in descending order, according to n d The value of n is found in the set L pi The value of n d The corresponding distances of two adjacent items are l1 and l2, so let And execute step 2) to step 6);

[0090] 9) If n p =n d , at this time, the tree point coordinate set P is a uniformly arranged set.

[0091] As an optional implementation, after planning and designing based on the preset number of trees and the vector data to determine the tree point coordinate set of the green area in step S102, and before step S103, the following steps may also be performed:

[0092] The horizontal coordinate and the vertical coordinate of each tree point coordinate are randomly offset to obtain candidate tree point coordinates corresponding to each tree point coordinate; wherein the difference between the horizontal coordinate of the candidate tree point coordinate and the horizontal coordinate of the corresponding tree point coordinate is within a preset difference range; and the difference between the vertical coordinate of the candidate tree point coordinate and the vertical coordinate of the corresponding tree point coordinate is within the preset difference range;

[0093] If the candidate tree point is within the planar green area, the tree point coordinates corresponding to the candidate tree point are replaced with the coordinates of the candidate tree point;

[0094] If the candidate tree point is within the planar green area, the candidate tree point is deleted.

[0095] Among them, by implementing this implementation method, the horizontal and vertical coordinates of each tree point coordinate can be randomly offset to obtain adjusted candidate tree point coordinates, and the candidate tree point coordinates that are still in the flat green area can be determined as new tree point coordinates to make the tree point coordinates more diversified and enhance the ornamental value of the tree landscape.

[0096] In the embodiment of the present invention, the preset difference range of the random offset can be

[0097] Step S103: determining planning and design information of candidate trees in the green area based on the geographical location information, the vector data and the tree point coordinate set.

[0098] In the embodiment of the present invention, the candidate tree planning and design information includes the tree point coordinate set and the target tree model corresponding to each of the tree point coordinates.

[0099] Optionally, a tree and plant library can be constructed, which can include tree model information; the tree model information can include the height of the tree type, coverage area, altitude and latitude suitable for growth, tree age, growth coefficient, etc., which is not limited to this embodiment of the present invention.

[0100] As an optional implementation manner, the method of determining the candidate tree planning and design information of the green area based on the geographic location information, the vector data and the tree point coordinate set in step S103 may include the following steps:

[0101] Acquire the elevation data of each of the tree point coordinates from the vector data;

[0102] determining a tree cover area based on the tree spacing;

[0103] Based on the geographic location information, the elevation data, the tree coverage area and the tree point coordinate set, candidate tree planning and design information of the green area is determined.

[0104] Among them, by implementing this implementation method, the elevation data of each tree point coordinate can be obtained from the vector data, and the tree coverage area can be calculated based on the tree spacing, and then the matching tree model can be determined according to the geographic location information, the elevation data, and the tree coverage area, and then the candidate tree planning and design information of the green area can be obtained based on the obtained tree model and the tree point coordinate set. It can be seen that by implementing this implementation method, the tree model in the obtained candidate tree planning and design information can be matched with the local geographic information, and the tree model with the appropriate height can be selected according to the elevation data of the tree point coordinates, and the tree model with the tree coverage area meeting the requirements can also be selected, thereby improving the accuracy of the candidate tree planning and design information.

[0105] In the embodiment of the present invention, the vector data may include a digital elevation model (DEM) of the green area, and the tree point coordinates are input into the digital elevation model, and the elevation data corresponding to the tree point coordinates can be output.

[0106] In the embodiment of the present invention, the calculation formula of the tree coverage area S′ may be:

[0107]

[0108] Step S104, inputting the candidate tree planning and design information and the preset growth years into a pre-built three-dimensional planning model of a residential area, and obtaining the maximum view occlusion rate and the shortest sunshine duration corresponding to the candidate tree planning and design information.

[0109] In an embodiment of the present invention, the three-dimensional planning model of the residential area can calculate the scaling ratio of the tree model according to the age and growth coefficient of the tree species, scale the tree model at each point respectively, extract the building surface data from the planning data, interpolate a series of points at certain intervals along the edge of the building surface and the building height direction, perform visual range analysis on each point respectively, and obtain the maximum visual range occlusion rate, perform sunshine analysis on each side of the building, and obtain the shortest sunshine duration.

[0110] Step S105: if the maximum view occlusion rate is less than the preset occlusion rate and the shortest sunshine duration is greater than the preset sunshine duration, the candidate tree planning and design information is determined as the target tree planning and design information.

[0111] In the embodiment of the present invention, if the maximum viewing area occlusion rate is greater than or equal to the preset occlusion rate, or the shortest sunshine duration is less than or equal to the preset sunshine duration, the following steps may also be performed:

[0112] The growing years, the preset number of trees and the green area are updated to obtain updated growing years, the preset number of trees and the green area;

[0113] Based on the updated growing years, the preset number of trees and the green area, steps S102 to S104 are executed.

[0114] Among them, by implementing this implementation method, when the maximum visual area obstruction rate and the shortest sunshine duration do not meet the preset conditions, the growth years, the preset number of trees and the green area can be updated, and steps S102 to S104 can be repeatedly executed, so that the obtained target tree planning and design information can meet the preset conditions, thereby ensuring the reliability of the target tree planning and design information.

[0115] The present invention can take into account the three-dimensional space in the residential area during the planning of the green area, avoiding the situation where the tree landscape blocks the windows of the residence, resulting in a smaller visual area of ​​the residents' houses or too short sunshine duration, thereby improving the effect of the landscape design scheme in practical application. In addition, the present invention can also make the tree point coordinate set more intuitive to determine. In addition, the present invention can also improve the rationality of the tree point coordinates. In addition, the present invention can also improve the ornamental value of the tree landscape. In addition, the present invention can also improve the accuracy of the candidate tree planning and design information.
