In this embodiment, a method for processing object attributes based on a polygon area set, as shown in fig. 2, includes:

(A) Acquiring an object E to be processed with polygonal boundary data; creating a polygon area object R0 describing a default value of an attribute P of the object E, and adding the R0 into a polygon area set Rs describing the attribute P of the object E;

(D) Application of a set of polygonal areas Rs for describing the properties P of the object E.

The method comprises the steps that an object E is provided with a polygonal boundary, a polygonal area set Rs is a container object, aggregate elements in the polygonal area set Rs are polygonal areas and are used for describing the condition that an attribute P of the object E has different values in subareas in the polygonal boundary of the object E, the polygonal area set Rs manages polygonal area objects in the container in a layered mode, the polygonal area is a data structure and is defined in a class or structure body mode, boundary attribute Bd records boundary point coordinate data of orderly arranged polygonal areas, numerical attribute Va records values of the attribute P of the object E in the polygonal area boundary, layer number attribute Ly records layer numbers of the polygonal area, and the values of boundary attribute Bd of the polygonal area object R0 are taken from the polygonal boundary data of the object E; the value of the numeric attribute Va of the polygon area object R0 is taken from the default value P0 of the attribute P of the object E; the value of the layer number attribute Ly of the polygon area object R0 is taken from the reference layer number L0 used for the current polygon area object creation.

The step (B) is that the attribute P of the object E has different values in a certain sub-region, which means that a plurality of sub-regions are divided within the polygon boundary of the object E, wherein the values of the attribute P of the object E in each sub-region are different, there is no limitation on the number of the sub-regions divided within the polygon boundary of the object E, and the attribute P of the processing object E has different values in the sub-region, which means that a polygon area object Ri matching with the sub-region Zi is created, and after assigning each member attribute of the polygon area object Ri, the polygon area object Ri is added to the polygon area set Rs describing the attribute P of the object E.

The step (C) is that the management of the polygon area set Rs for describing the attribute P of the object E is a process of adding, inserting, modifying and deleting the polygon area set Rs set elements describing the attribute P of the object E and a process of saving and recovering the polygon area set Rs describing the attribute P of the object E.

The step (D) is that the application of the polygon area set Rs for describing the attribute P of the object E refers to the quick and accurate solving conclusion of the value of the attribute P of the object E at any specified position Pos.

(A) Acquiring an object E to be processed with polygonal boundary data; setting a layer number used for creating a current polygon area object to be L0; a polygon area object R0 describing the default value of the attribute P of the object E is created, and after assigning each member attribute of the polygon area object R0, the polygon area object R0 is added to the polygon area set Rs describing the attribute P of the object E.

Here, the polygon area objects in the polygon area set Rs are managed in a hierarchical manner, and the positions of layers where the polygon area objects are located are indicated from small to large in layer numbers from bottom to top.

Here, the polygon area refers to a data structure defined in the form of a class or a structure body, the boundary attribute Bd records coordinate data of boundary points of the polygon area sequentially arranged, the numerical attribute Va records a value of an attribute P of an object E in the boundary of the polygon area, and the layer number attribute Ly records a layer number where the polygon area is located.

For the above specific embodiment, the creation of the polygon area object R0, adding the polygon area object R0 to the polygon area set Rs describing the attribute P of the object E, is performed as follows:

(A1) An object E having polygon boundary data is acquired.

(A2) Setting the layer number used for creating the current polygon area object as L0, setting the value of L0 as 0, creating the polygon area object R0, and assigning values to each member attribute of the polygon area object R0, wherein the method comprises the following steps:

the value of the boundary attribute Bd of the (A2-1) polygon area object R0 is taken from the polygon boundary data of the object E.

The value of the numeric attribute Va of (A2-2) the polygonal area object R0 is taken from the default value P0 of the attribute P of the object E.

The value of the layer number attribute Ly of (A2-3) polygon area object R0 is taken from the layer number L0 used for the current polygon area object creation.

(A3) The polygon area object R0 is added to the polygon area set Rs describing the attribute P of the object E.

Here, the polygon area object R0 describes the default value of the attribute P of the object E as the lowest-layer member in the polygon area set Rs describing the attribute P of the object E.

(B) The case where the attribute P of the object E has different values for each sub-region within the polygon boundary of the object E is handled.

Here, the case where the attribute P of the object E has different values in a certain sub-region means that a plurality of sub-regions are divided within the polygon boundary of the object E, wherein the value of the attribute P of the object E is different in each sub-region.

Here, there is no limitation on the number of division of the sub-regions within the polygon boundary of the object E.

Here, the condition that the attribute P of the processing object E has different values in a certain sub-region refers to creating a polygon area object Ri matching with the sub-region Zi, assigning a value to each member attribute of the polygon area object Ri, and adding the polygon area object Ri to the polygon area set Rs describing the attribute P of the object E.

Here, when the attribute P of the processing object E has different values in a certain sub-region, the following steps are performed:

(B1) Judging: if there is no case where the attribute P of the unprocessed object E has a different value in a certain sub-region, performing step (B2); if there is a case where the attribute P of the unprocessed object E has different values in a certain sub-area, the processing is performed as follows:

(B1-1) selecting sub-regions Zi in which the attribute P of a certain unprocessed object E has different values.

(B1-2) setting the layer number used for creation of the current polygon area object to Li.

Here, the value of the layer number Li is set to be the value of the layer number Li-1 of the previous layer plus a constant value, for example, 10, which can represent different positions of the layer where the polygon area object is created, and simultaneously meet the requirement of inserting the set element in the polygon area set Rs describing the attribute P of the object E.

(B1-3) creating a polygonal area object Ri, assigning values to each member attribute of the polygonal area object Ri, according to the following steps:

the value of the boundary attribute Bd of the (B1-3-1) polygonal area object Ri is taken from the polygonal boundary data of the sub-area Zi.

Here, the polygon boundary data of the sub-region Zi is acquired by the "minimum closed region discovery method (patent No. ZL 201410385509.2) surrounding a given point in a two-dimensional graph" patent technology.

Here, polygon boundary data of the sub-region Zi is acquired, and the following steps are performed:

(B1-3-1-1) creating an empty aggregate container S to accommodate the line segments and/or the polyline.

(B1-3-1-2) traversing all the polygon area objects in the polygon area set Rs of the attribute P of the object E, for each polygon area object Rj, processing the related data as follows:

and (B1-3-1-2-1) judging: if the value of the layer number attribute Ly of the polygon area object Rj is smaller than the layer number Li used for the current polygon area object creation, the value of the boundary attribute Bd of the polygon area object Rj is added to the container S.

(B1-3-1-3) if necessary, providing auxiliary line segments or auxiliary folding lines, added to the container S, enabling members in the container S to form a closed figure that describes the polygonal boundary of the sub-region Zi.

Here, providing the auxiliary line segment or auxiliary broken line as necessary means providing the corresponding auxiliary line segment or auxiliary broken line only when the boundary attribute Bd of the polygon area object conforming to the condition cannot be enclosed to form the closed polygon boundary describing the sub-area Zi.

(B1-3-1-4) selecting any point Pt within the polygonal boundary of the sub-region Zi.

(B1-3-1-5) acquiring data describing a polygonal boundary of the sub-region Zi by using the collective elements in the container S and the selected point Pt and using a "minimum closed region discovery method (patent number ZL 201410385509.2) for surrounding the given point in a two-dimensional graph" patent technique.

The value of the numerical attribute Va of the (B1-3-2) polygonal area object Ri is taken from the value Pi of the attribute P of the object E within the sub-area Zi.

The value of the layer number attribute Ly of the (B1-3-3) polygonal area object Ri is taken from the layer number Li used for the current polygonal area object creation.

(B1-4) adding the polygonal area object Ri to the polygonal area set Rs describing the attribute P of the object E.

(B1-5) returning to step (B1).

(B2) The processing is completed in the case where the attribute P of the object E has different values in a certain sub-area.

(C) Management of a set of polygonal areas Rs for an attribute P describing an object E, comprising the steps of:

(C1-1) adding, inserting, modifying, deleting the set elements in the polygon area set Rs describing the attribute P of the object E as required.

Here, in performing the insert operation on the set element in the polygon area set Rs describing the attribute P of the object E, it is necessary to set the value of the layer number where the current polygon area object is created to a value between the values of the member attribute layer numbers Ly of the upper and lower adjacent layer polygon area objects.

(C1-2) saving a polygon area set Rs describing an attribute P of the object E.

Here, the polygon area set Rs describing the attribute P of the object E is saved in order to be able to restore the polygon area set Rs describing the attribute P of the object E when reconstructing the object E, instead of being recreated.

Here, when the polygon area set Rs describing the attribute P of the object E is saved and restored, it is necessary to perform serialization and deserialization processing on the polygon area set Rs describing the attribute P of the object E.

(D) The application of the polygonal area set Rs for describing the property P of the object E is performed as follows:

(D1) The position Pos at which the value of the attribute P of the object E is to be acquired is given.

(D2) Judging: if the position Pos is outside the polygon boundary range of the object E, the value of the attribute P of the object E cannot be obtained, the solution fails, and step (D3) is executed; if the position Pos is within the polygon boundary of the object E, the following steps are performed:

(D2-1) the set elements in the polygon area set Rs describing the attribute P of the object E are arranged in descending order of layer number Ly.

Here, the collective elements in the polygon area set Rs describing the attribute P of the object E are arranged in descending order of layer number Ly, so as to be performed in order from top to bottom of the layers in which the polygon area objects in the polygon area set Rs are located when solving the value of the attribute P of the object E to traverse the polygon area objects.

(D2-2) sequentially looping all the polygonal area objects in the polygonal area set Rs of the attribute P of the processing object E, according to the following steps:

(D2-2-1) setting the value of the cycle counter K to 1.

(D2-2-2) sequentially fetching the kth polygonal-area object Rk from the polygonal-area set Rs of the attribute P of the object E.

And (D2-2-3) judging: if the position Pos is within the range of the boundary attribute Bd of the polygon area object Rk, the value of the attribute P of the object E is equal to the value of the numerical attribute Va of the polygon area object Rk, the solving is successful, the loop is interrupted, and the step (D3) is executed; if the position Pos is outside the boundary attribute Bd of the polygon area object Rk, the loop counter K is incremented by 1, and the process returns to step (D2-2-2) to execute the next loop.

(D3) And outputting a solving conclusion, and ending the solving work.

Here, when the value of the attribute P of the specified position object E cannot be acquired, outputting a corresponding prompt; when the value of the attribute P of the specified position object E is successfully acquired, the obtained attribute value is output.

In fig. 2, a to-be-processed object E having polygon boundary data is first acquired (step S101).

Then, the polygon area R0 of the L0 th layer is created and processed, and after assigning values to the respective member attributes of the polygon area object R0, the polygon area object R0 is added to the polygon area set Rs describing the attribute P of the object E (step S102).

Here, the value of the boundary attribute Bd of the polygon area R0 of the L0 th layer is taken from the polygon boundary data of the object E, and the value of the numerical attribute Va of the polygon area R0 is taken from the default value P0 of the attribute P of the object E.

Then, the attribute P of the processing object E has a different value in a certain sub-region.

First, it is determined whether or not the attribute P of the unprocessed object E has a different value in a certain sub-area (step S103).

If there is a case where the attribute P of the unprocessed object E has a different value in a certain sub-region, the polygon area Ri of the Li-th layer is created and processed and added to the polygon area set Rs (step S104), and then returned (step S103).

If there is no case where the attribute P of the unprocessed object E has a different value in a certain sub-region, the polygon area set Rs describing the attribute P of the object E is managed (step S105).

Here, the processing of adding, inserting, modifying, deleting, etc. the set elements in the polygon area set Rs describing the attribute P of the object E is mainly completed as needed, and the processing of saving and restoring the polygon area set Rs describing the attribute P of the object E is completed.

Then, an application may be made for the polygon area set Rs describing the attribute P of the object E (step S106).

Here, the creation and management of the polygon area set Rs describing the attribute P of the object E have been completed, and for any given position, a solution conclusion of the value of the attribute P of the object E can be conveniently and quickly obtained.
