Description

Background Art

[0002] In the general layout design and construction management of industrial enterprises, it is necessary to count the paved area of roads. Due to the complex road network in industrial enterprises, there are many styles and quantities of various intersections, connection ports, and vehicle yards. Counting the road area is a relatively complex and cumbersome task. At present, various software cannot directly count the road area, and the method of pattern filling is used to count the road area. Using this method, it is necessary to first close the boundary, then perform pattern filling, and finally accumulate to obtain the total area. The main disadvantages are cumbersome operation, low efficiency, and easy to make mistakes. If the road area can be directly counted, the work efficiency and quality will be greatly improved.

[0003] Based on this, the present invention proposes a statistical calculation method, system, and device for the road area of industrial enterprises. Summary of the Invention

[0004] In order to solve the above problems in the prior art, that is, the problems of cumbersome operation, low efficiency, and easy to make mistakes in the prior art, the present invention provides a statistical calculation method, system, and device for the road area of industrial enterprises.

[0005] In the first aspect of the present invention, a statistical calculation method for the road area of industrial enterprises is provided. The method includes the following steps:

[0006] Step S10, obtain the road drawing whose area is to be calculated, obtain the side line and center line in the road drawing, and establish a side line set and a center line set;

[0007] Step S20, obtain any drawing line in the side line set, and judge whether the drawing line is a straight line or an arc line; when the drawing line is a straight line, jump to step S30, otherwise jump to step S40;

[0008] Step S30, obtain the two end points of the straight line, and obtain the two virtual points on the center line that are the closest to the center line from the two end points. Generate a first block based on the end points and the virtual points, calculate the area of the first block, and jump to step S20 until all the straight lines in the side line set are judged, then jump to step S50;

[0009] Step S40, obtain the starting point, ending point, center point, and radius of the arc line; obtain the shortest distances from the starting point and the ending point to the center line, and form virtual line segments; generate a second block based on the virtual line segments, the center line, the starting point, and the ending point, calculate the area of the second block, and jump to step S20 until all the arc lines in the side line set are judged, then jump to step S50;

[0010] Step S50: Accumulate the areas of multiple said first blocks and the areas of multiple said second blocks to obtain the road area.

[0011] In some preferred embodiments, for the said first block, its generation method is as follows:

[0012] Connect the said endpoint with the virtual point closest to it to obtain a virtual straight line segment as the partition line, and use the block enclosed by the partition line, the center line, and the straight line as the first block. The fixed points of the first block are two endpoints and at least one virtual point.

[0013] In some preferred embodiments, for the area of the said first block, its calculation method is as follows:

[0014] Judge whether two virtual points coincide. If so, the first block is a triangle, and use the area calculation model of a triangle to calculate the area of the first block;

[0015] If not, the first block is a quadrilateral, and use the area calculation model of a quadrilateral to calculate the area of the first block; the quadrilateral includes a trapezoid, a rectangle, or a square.

[0016] In some preferred embodiments, for the said second block, its generation method is as follows:

[0017] When the virtual line segment intersects one of the center lines in the set of center lines, judge whether the center line connected to the starting point and the ending point is the same center line;

[0018] If it is the same center line, use the block enclosed by the center line, the virtual line segment, and the arc line as the second block;

[0019] If it is not the same center line, use the block enclosed by multiple said center lines, the virtual line segment, and the side line as the second block.

[0020] In some preferred embodiments, when the virtual line segment intersects both of the two center lines in the set of center lines, extract the arc line on the other side corresponding to the arc line in the set of side lines. When there is only one center line between the two arc lines, use this center line as the center line to be calculated. Respectively obtain the shortest distances from the starting points and ending points of the two arc lines to the center line to be calculated, and generate a virtual line segment. Use the block enclosed by the virtual line segment, the center line to be calculated, and the arc line as the second block.

[0021] In some preferred embodiments, for the area of the said second block, its calculation method is as follows:

[0022] When the center line connecting the starting point and the ending point is the same center line, the second block is a three-sided and one-arc block, and the area of the second block is calculated by combining the concavity and convexity of the arc line in the three-sided and one-arc block;

[0023] When the center line connecting the starting point and the ending point is not the same center line, the second block is a four-sided and one-arc block, and the area of the second block is calculated by combining the concavity and convexity of the arc line in the four-sided and one-arc block.

[0024] In some preferred embodiments, the block enclosed by the virtual line segment, the center line to be calculated, and the arc line is a sector ring block, and the area of the second block is calculated by combining the calculation model of the sector ring block.

[0047] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related invention, rather than limiting the invention. Additionally, it should be noted that, for the sake of convenience of description, only the parts related to the relevant invention are shown in the drawings.

[0048] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and embodiments.

[0049] In the first embodiment of the present invention, a statistical calculation method for the road area of industrial enterprises is provided. The method includes the following steps:

[0050] Step S10: Obtain the road drawing whose area is to be calculated, obtain the side lines and the center line in the road drawing, and establish a side line set and a center line set;

[0051] Step S20: Obtain any one graphic line in the side line set, and determine whether the graphic line is a straight line or an arc line; when the graphic line is a straight line, jump to step S30, otherwise jump to step S40;

[0052] Step S30: Obtain the two endpoints of the straight line, and obtain the two virtual points on the center line that are the closest to the two endpoints from the center line. Generate a first block based on the endpoints and the virtual points, calculate the area of the first block, and jump to step S20. Until all the straight lines in the side line set are judged, jump to step S50;

[0053] Step S40: Obtain the starting point, ending point, center point, and radius of the arc line; obtain the shortest distances from the starting point and the ending point to the center line, and form virtual line segments; generate a second block based on the virtual line segments, the center line, the starting point, and the ending point, calculate the area of the second block, and jump to step S20. Until all the arc lines in the side line set are judged, jump to step S50;

[0054] Step S50: Accumulate the areas of multiple first blocks and the areas of multiple second blocks to obtain the road area. This method.

[0055] To more clearly illustrate a method for statistically calculating the road area of an industrial enterprise according to the present invention, the following will describe in detail each step in the embodiments of the present invention in combination with Figure 1 Expand and describe each step in the embodiments of the present invention in detail.

[0056] A method for statistically calculating the road area of an industrial enterprise according to the first embodiment of the present invention includes steps S10 - S50, and each step is described in detail as follows:

[0057] Step S10: Obtain the road drawing of the area to be calculated, obtain the side lines and center lines in the road drawing, and establish a side line set and a center line set;

[0058] Among them, the road drawing is a DWG format file; the drawn road lines only include two simple line types, namely line segments and arcs, and do not include complex line types such as spline curves; all road center lines are located on the same layer, and the line type is center line or dotted line; all road side lines are located on the same layer, and the line type is solid line; the layers where the road side lines are located and the layers where the center lines are located do not contain other line drawings.

[0059] Among them, establish a road side line set B and a road center line set C. Using two elements, namely the layer and the line type, as combined conditions, through programming, automatically search the graphic database, compare the layer and line type of each line one by one, extract all road side lines that meet the conditions into the set B, and extract all road center lines that meet the conditions into the set C. To implement this process, generally use the API function acedSSGet. The input of the screening conditions for the layer and the line type can be achieved by selecting samples and then extracting the layer name and line type name.

[0060] Step S20: Obtain any one line in the side line set, and determine whether the line is a straight line or an arc line; when the line is a straight line, jump to step S30, otherwise jump to step S40;

[0061] Step S30: Obtain the two endpoints of the straight line, and obtain the two virtual points on the center line that are the closest to the center line from the two endpoints. Generate a first block based on the endpoints and the virtual points, calculate the area of the first block, and jump to step S20. Until all the straight lines in the side line set are judged, then jump to step S50;

[0062] Among them, the generation method of the first block is as follows:

[0063] Connect the endpoint with the virtual point closest to it to obtain a virtual straight line segment as the partition line, and use the block enclosed by the partition line, the center line, and the straight line as the first block. The fixed points of the first block are the two endpoints and at least one virtual point.

[0064] Among them, the area of the first block is calculated as follows:

[0065] Determine whether two virtual points coincide. If so, the first block is a triangle, and the area of the first block is calculated using the area calculation model of a triangle;

[0066] If not, the first block is a quadrilateral, and the area of the first block is calculated using the area calculation model of a quadrilateral; the quadrilateral includes a trapezoid, a rectangle or a square.

[0067] Specifically, extract the first graphic line B1 from the road boundary line set B.

[0068] If the extracted graphic line B1 is a straight line segment, obtain two end points pt11 and pt12.

[0069] Traverse each straight line segment in the center line set C. For any straight line segment C1, calculate the closest points pt21 and pt22 from pt11 and pt12 to the straight line C1 respectively, forming two virtual straight line segments. One is the virtual line segment from pt11 to pt21, and the other is the virtual line segment from pt12 to pt22. To find the point on the line segment that is closest to the specified point, the API function getClosestPointTo can be used.

[0070] Traverse the other graphic lines in the boundary line set B except B1. If none of the other graphic lines intersect with these two virtual line segments, it is considered that B1 and C1 form a block, and the boundary points of the block are pt11, pt12, pt22, and pt21.

[0071] If pt21 and pt22 coincide, the formed block is a triangle, and use Figure 2 Calculate the area of the triangle. The area of the triangle can be calculated using Heron's formula, Figure 2 where a, b, and c in it are the lengths of the three sides of the triangle respectively.

[0072] If pt21 and pt22 do not coincide, the formed block is a trapezoid, and use Figure 3 Calculate the area of the trapezoid. In most cases, this trapezoid is a rectangle, and it may only be a trapezoid in special cases. The area calculation method of the trapezoid is used in all cases, Figure 3 where a in it is the length of the short side of the trapezoid, b is the length of the long side of the trapezoid, and h is the height of the trapezoid.

[0073] Step S40: Obtain the starting point, ending point, center point, and radius of the arc line; obtain the shortest distances from the starting point and the ending point to the center line, and form virtual line segments; generate a second block based on the virtual line segments, the center line, the starting point, and the ending point, calculate the area of the second block, and jump to step S20. Until all the arc lines in the set of side lines are judged, jump to step S50;

[0074] Among them, the method for generating the second block is as follows:

[0075] When the virtual line segment intersects with one of the center lines in the set of center lines, it is judged whether the center lines connected to the starting point and the ending point are the same center line;

[0076] If they are the same center line, the block enclosed by the center line, the virtual line segment, and the arc line is used as the second block;

[0077] If they are not the same center line, the blocks enclosed by multiple center lines, the virtual line segment, and the side lines are used as the second block.

[0078] In the present invention, when the virtual line segment intersects with both of the center lines in the set of center lines, the arc line on the other side corresponding to the arc line is extracted from the set of side lines. When there is only one center line between the two arc lines, the center line at this time is used as the center line to be calculated. The shortest distances from the starting points and the ending points of the two arc lines to the center line to be calculated are obtained respectively, and virtual line segments are generated. The block enclosed by the virtual line segments, the center line to be calculated, and the arc line is used as the second block.

[0079] In the present invention, the method for calculating the area of the second block is as follows:

[0080] When the center lines connected to the starting point and the ending point are the same center line, the second block is a three-sided and one-arc block, and the area of the second block is calculated by combining the concavity and convexity of the arc line in the three-sided and one-arc block;

[0081] When the center lines connected to the starting point and the ending point are not the same center line, the second block is a four-sided and one-arc block, and the area of the second block is calculated by combining the concavity and convexity of the arc line in the four-sided and one-arc block.

[0082] In the present invention, the block enclosed by the virtual line segments, the center line to be calculated, and the arc line is a fan-shaped ring block, and the area of the second block is calculated by combining the calculation model of the fan-shaped ring block.

[0083] Specifically, the center point center, starting point start, ending point end, and radius R of the arc line are extracted.

[0084] Traverse the set C of centerlines, obtain the line segment TX1, calculate the nearest point s1 from the starting point start of the circular arc edge B1 to the line segment TX1, and form a virtual line segment XN1.

[0085] Traverse the other lines in the set B of edges except the line segment B1. If none of the other lines intersect this virtual line segment XN1, then it is considered that the centerline TX1 is a centerline corresponding to this circular arc edge.

[0086] Traverse the set C of centerlines, obtain the line segment TX2, calculate the nearest point s2 from the ending point end of the circular arc edge B1 to the line TX2, and form a virtual line segment XN2.

[0087] Traverse the other lines in the set B of edges except the line segment B1. If none of the other lines intersect this virtual line segment XN2, then it is considered that the centerline TX2 is another centerline corresponding to this circular arc edge.

[0088] If TX1 and TX2 are the same line segment, a three-side-one-arc type block is formed, and use Figure 4 to calculate its area. Among them, it is necessary to determine whether the circular arc is a concave arc or a convex arc. The determination method is to judge whether the center point of the arc is inside the quadrilateral. Then use the -1 or +1 coefficient K to represent the concave arc or the convex arc, and substitute it into the formula. Figure 4 where a and b are the lengths of two sides of the three-side-one-arc type block, h is the height of the three-side-one-arc type block, R is the radius of the circular arc line, and θ is the angle between the starting point and the ending point of the circular arc line in the three-side-one-arc type block to the connection line of the center of the circle.

[0089] If TX1 and TX2 are not the same line segment, calculate the intersection point of the line segments TX1 and TX2, form a four-side-one-arc type block, and use Figure 5 to calculate its area, where w1 and w2 are the lengths of the two short sides of the four-side-one-arc type block, and θ is the angle between the starting point and the ending point of the circular arc line in the four-side-one-arc type block to the connection line of the center of the circle.

[0090] If no line segment that meets the conditions can be found and a three-side-one-arc type block or a four-side-one-arc type block cannot be constructed, then find another corresponding circular arc B2 from the set B of edges. It is judged that there is and only one centerline between the circular arcs B1 and B2. At this time, a fan-shaped ring block is formed, and use Figure 6 to calculate the area, where R1 and R2 are the radii of the two circular arc lines respectively, and θ is the angle between the starting point and the ending point of the circular arc line in the fan-shaped ring block to the connection line of the center of the circle.

[0091] Among them, the calculation models of the above-mentioned blocks are all prior arts and will not be elaborated here.

They can be executed simultaneously (in parallel) or in reverse order, and these simple changes are all within the protection scope of the present invention.

[0094] A drawing acquisition module, which acquires the road drawing for which the area is to be calculated, acquires the side lines and the center line in the road drawing, and establishes a side line set and a center line set;
