Description
Technical Field
[0001] The present application relates to the technical field of photovoltaic power station construction, and in particular to a method and system for grouping triangular faces in mountainous terrain. Background Art
[0002] In recent years, with the flat terrain, the land resources with good construction conditions have been decreasing, which cannot meet the needs of the construction of photovoltaic power stations in the process of vigorous development. Gradually, the number of photovoltaic power stations built in hilly and mountainous areas with complex terrain is increasing.
[0003] At present, most photovoltaic power stations in the southwest region with good solar energy resources are built on wasteland, sparse forests and hillsides. In the early stage of photovoltaic power station construction, if the triangular surfaces of the mountain become the key to the construction of the photovoltaic power station, it is urgent to propose a scheme that can accurately group the triangular surfaces of the mountain terrain to provide support for the subsequent construction of photovoltaic power stations.

[0007] Screening each angle in the first angle set according to a preset angle threshold to obtain a second angle set;
[0008] Grouping is performed on each angle in the second angle set to obtain the group to which each angle in the second angle set belongs.
[0009] Preferably, the step of screening the angles in the first angle set according to a preset angle threshold to obtain a second angle set includes:
[0010] The angles between the triangular faces and the horizontal plane that are greater than the preset angle threshold are screened out from the first angle set, and the angles between the triangular faces and the horizontal plane that are greater than the preset angle threshold are eliminated to obtain a second angle set.
[0011] Furthermore, the preset angle threshold is the maximum value of the angle between the triangular surface used for photovoltaic power station construction and the horizontal plane.
[0012] Furthermore, the grouping of the angles in the second angle set to obtain the group to which the angles in the second angle set belong includes:

[0016] Furthermore, the method further comprises:
[0017] The triangular faces corresponding to the angles in the first group, the second group, and the third group are rendered in different colors respectively.
[0018] The second embodiment of the present application provides a grouping system for mountain terrain triangles, including:
[0019] An acquisition module, used for obtaining the angles between each triangle of the mountainous terrain and the horizontal plane by dividing the geometric information of the Delaunay triangle based on the terrain, so as to form a first angle set;
[0020] A screening module, used for screening each angle in the first angle set according to a preset angle threshold to obtain a second angle set;
[0021] A grouping module is used to group the angles in the second angle set to obtain the group to which the angles in the second angle set belong.
[0022] Preferably, the screening module is also used for:
[0023] The angles between the triangular faces and the horizontal plane that are greater than the preset angle threshold are screened out from the first angle set, and the angles between the triangular faces and the horizontal plane that are greater than the preset angle threshold are eliminated to obtain a second angle set.
[0024] Furthermore, the preset angle threshold is the maximum value of the angle between the triangular surface used for photovoltaic power station construction and the horizontal plane.
[0025] Furthermore, the grouping module is also used for:
[0026] Filtering out angles between triangular faces and horizontal planes whose angle values fall within a preset first angle range from the second angle set, and dividing the angles into a first group;
[0027] Screening out angles between triangular faces and horizontal planes whose angle values fall within a preset second angle range from the second angle set, and dividing the angles into a second group;
