Detailed Description

In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein.

In the prior art, when building arrangement planning design is performed by adopting a mode of arranging buildings along a boundary of a plot, a building designer usually determines an area where building occlusion may occur at a corner of the plot artificially, and the artificially determined mode has a high requirement on the personal level of the building designer, namely, whether the area where building occlusion may occur is accurately determined depends on the personal level of the building designer to a great extent.

In view of the problems in the prior art, the embodiment of the present application provides an intelligent method for determining an area where buildings arranged at corners of a plot are blocked by each other, and an electronic device can accurately determine an area where building blocking may occur at corners of a plot based on the method provided by the embodiment of the present application, so that accuracy of blocking area determination is no longer limited by personal level of a building designer.

Specifically, in the method for determining the area where buildings arranged at corners of a parcel are blocked, the electronic device determines an included angle at which a building blocking phenomenon may occur on a target parcel as a target included angle according to a boundary of the target parcel; and then determining an area formed by target points in the target plot as a shielding area, wherein the distance between the target point and a first edge of a target included angle is smaller than a first preset distance, and the distance between the target point and a second edge of the target included angle is smaller than a second preset distance, the first preset distance is not smaller than the depth of the building arranged along the first edge, and the second preset distance is not smaller than the depth of the building arranged along the second edge. The electronic equipment can accurately determine the area where the building shielding possibly occurs at the included angle of the plot based on the method, so that the positioning process of the shielded area completely gets rid of architects, and the positioning accuracy of the shielded area is guaranteed not to be limited by the personal level of the architects.

It should be noted that the electronic device for executing the method for determining the area where buildings arranged at corners of a parcel are blocked by each other provided in the embodiments of the present application may specifically be a terminal device or a server. The terminal device may be a computer, a smart phone, a tablet computer, or the like. The server can be a web server or an application server.

The following describes a method provided by the present application for determining an area where buildings disposed at corners of a parcel block each other by way of example.

It should be noted that the technical solution provided in the embodiment of the present application is applied to the field of building design, and when building arrangement and layout timing is performed on an actually existing land, an area where building occlusion may occur at a corner of the land can be determined by the method provided in the embodiment of the present application. The building is specifically a building above the ground, and considering that many plots are complex in practical application and the ground heights at different positions are different, the building above the ground is a building above the ground at the position.

Referring to fig. 1, fig. 1 is a schematic flowchart of a method for determining an area where buildings disposed at corners of a parcel block from each other according to an embodiment of the present application. It should be noted that the flow shown in fig. 1 may be implemented by a shape library of Python related to geometry processing in an electronic device. As shown in fig. 1, the method for determining an area where buildings disposed at corners of a parcel block are obstructed from each other includes the steps of:

step 101: and determining an included angle which is possibly subjected to building shielding phenomenon on the target plot according to the boundary of the target plot, and taking the included angle as the target included angle.

When the electronic device adopts the mode of arranging the buildings along the boundaries of the plot to arrange the buildings on the target plot, in order to prevent the buildings arranged at the corners from being shielded, the area on the target plot, which may be shielded by the buildings, needs to be determined.

Considering that the target parcel is not of a regular geometric shape in many cases, the boundary on the target parcel that is approximated by a long straight side may be substantially composed of a plurality of short sides, or may be composed of a plurality of approximately parallel long straight sides. The above situation has a great influence on the judgment of the target included angle, and in order to ensure that the target included angle is accurately found, the electronic device may firstly perform normalization processing on the boundary of the target parcel.

Specifically, the electronic device may traverse each boundary of the target parcel, and merge two adjacent boundaries if an included angle between the two boundaries is smaller than a preset angle.

It should be noted that, here, the distance between two adjacent boundaries is within a preset distance range, where the distance between two boundaries refers to a distance between two nearest points on the two boundaries, respectively, and if it is determined that an included angle between straight lines where the two adjacent boundaries are located on the target parcel is smaller than a preset angle, it may be determined that the two adjacent boundaries are approximately parallel, at this time, the two boundaries may be merged, and normalization processing may be continuously performed on other boundaries of the target parcel based on the boundaries obtained after the merging processing.

It should be understood that the preset angle may be set according to actual requirements, for example, set to 2 °, and the preset angle is not specifically limited herein.

After the normalization processing of each boundary on the target parcel is completed, the electronic device may further search an included angle, which may cause a building shielding phenomenon, on the target parcel as the target included angle, based on the boundary of the target parcel after the normalization processing.

In specific implementation, the electronic device may determine, for a first target boundary on a target parcel, a boundary, as a second target boundary, where a distance between the electronic device and the first target boundary is smaller than a preset distance and a length of the boundary is greater than a second preset length; and further, determining an included angle between the first target boundary and the second target boundary, and if the included angle between the first target boundary and the second target boundary is smaller than a preset angle, determining the included angle between the first target boundary and the second target boundary as a target included angle which is possible to cause building shielding.

The process of determining the target included angle is described below by way of example, assuming that the first preset length and the second preset length are both 30m, the preset distance is 5m, and the preset angle is 120 °. For the boundary of the normalized target parcel, the electronic device may traverse all normalized boundaries on the target parcel in a clockwise or counterclockwise direction starting from any edge boundary, for each boundary, the electronic device may determine whether the length of the boundary is greater than 30m, determine that the boundary is a first target boundary if the length of the boundary is greater than 30m, and then searching a boundary which is less than 5m away from the first target boundary and has a length of more than 30m as a second target boundary, if the second target boundary which meets the above conditions is searched, the electronic equipment further determines an included angle between the first target boundary and the second target boundary, if the included angle between the first target boundary and the second target boundary is less than 120 degrees, determining the included angle between the first target boundary and the second target boundary as the included angle at which building occlusion is likely to occur, that is, determining the included angle between the first target boundary and the second target boundary as the target included angle.

It should be understood that the distance between two boundaries in the above essentially refers to the distance between the two closest points on the two boundaries, respectively. In addition, in practical application, the first preset length, the second preset length, the preset distance and the preset angle are not limited to the above-mentioned quantities, and the first preset length, the second preset length, the preset distance and the preset angle may be set according to practical requirements, and the first preset length, the second preset length, the preset distance and the preset angle in the application are not limited at all.

Step 102: determining an area formed by target points in the target land block as an occlusion area; the distance between the target point and the first edge of the target included angle is smaller than a first preset distance, the first preset distance is not smaller than the depth of a building arranged along the first edge, the distance between the target point and the second edge of the target included angle is smaller than a second preset distance, and the second preset distance is not smaller than the depth of the building arranged along the second edge.

After the electronic equipment determines the target included angle, an area formed by target points meeting preset conditions can be determined as a shielding area, and buildings are arranged in the shielding area, so that building shielding is most likely to occur.

It should be noted that the preset conditions that the target points need to satisfy are as follows: the distance between the target point and the first edge of the target included angle is smaller than a first preset distance, the distance between the target point and the second edge of the target included angle is smaller than a second preset distance, the first preset distance is not smaller than the depth of a building arranged along the first edge, and the second preset distance is not smaller than the depth of the building arranged along the second edge.

It should be noted that the first edge of the target included angle is one edge of the target included angle, and the second edge of the target included angle is the other edge of the target included angle, that is, the first edge and the second edge of the target included angle are two different edges forming the target included angle respectively.

In a possible implementation manner, the electronic device may determine the occlusion region by drawing parallel lines. Specifically, the electronic device may draw a first parallel line in an inward direction toward the target parcel, the first parallel line being parallel to a first side of the target angle and having a distance from the first side satisfying the first preset distance, and draw a second parallel line in an inward direction toward the target parcel, the second parallel line being parallel to a second side of the target angle and having a distance from the second side satisfying the second preset distance.

Furthermore, the electronic device may determine a region enclosed by the first side and the second side of the target included angle and the first parallel line and the second parallel line as a shielding region in the above, where a point in the shielding region is substantially the target point in the above, and satisfies a preset condition corresponding to the target point.

In another possible implementation manner, the electronic device may determine the occlusion region by drawing a rectangle. Specifically, the electronic device may draw a first target rectangle in an inward direction toward the target parcel based on a first side of the target angle and a vertex of the target angle, and draw a second target rectangle in the inward direction toward the target parcel based on a second side of the target angle and the vertex of the target angle.

In order to ensure that the area where building occlusion may occur at the corner can be accurately determined based on the drawn first target rectangle and the second target rectangle, in general, the length and width of the first target rectangle and the length and width of the second target rectangle need to be determined according to the depth of the building arranged along the first side of the target angle and the depth of the building arranged along the second side of the target angle. Specifically, the width of the first target rectangle and the length of the second target rectangle may be determined according to the depth of buildings arranged along the first side, and the width of the second target rectangle and the length of the first target rectangle may be determined according to the depth of buildings arranged along the second side.

The embodiment of the present application provides two exemplary implementations for drawing the first target rectangle and the second target rectangle, and the two implementations are described in detail below.

In a first implementation manner, the electronic device may determine, according to a local building specification, a first main face back distance corresponding to a first edge of the target included angle and a second main face back distance corresponding to a second edge of the target included angle; further, calculating a sum of the first main face back and the depths of the buildings arranged along the first side as a width of the first target rectangle and a length of the second target rectangle, and calculating a sum of the second main face back and the depths of the buildings arranged along the second side as a length of the first target rectangle and a width of the second target rectangle; drawing a first target rectangle towards the inward direction of the target land parcel by taking the vertex of the target included angle as one vertex of the first target rectangle, taking the first edge as the long edge of the first target rectangle and according to the length and the width of the first target rectangle; and drawing the second target rectangle towards the inward direction of the target land parcel according to the length and the width of the second target rectangle by taking the vertex of the target included angle as one vertex of the second target rectangle and the second side as the long side of the second target rectangle.

The main surface setback is a perpendicular distance between a boundary of the target parcel and a surface of the buildings arranged along the boundary facing the boundary, and accordingly, the first main surface setback is a perpendicular distance between the first edge and the surface of the buildings arranged along the first edge facing the first edge, and the second main surface setback is a perpendicular distance between the second edge and the surface of the buildings arranged along the second edge facing the second edge.

In order to facilitate understanding of the drawing process of the first target rectangle and the second target rectangle, the drawing process is exemplarily described below with reference to fig. 2. As shown in FIG. 2, the vertex of the target angle is point O, the first side of the target angle is OA, and the second side of the target angle is OB; one long side OC of the first target rectangle OCDE is located on the first side OA, the lengths OC and DE of the first target rectangle are equal to the sum of the second main face relief corresponding to the second side OB and the depth of the buildings arranged along the second side OB, and the widths OE and CD of the first target rectangle are equal to the sum of the first main face relief corresponding to the first side OA and the depth of the buildings arranged along the first side OA; one long side OH OF the second target rectangle OFGH lies on the second side OB, the lengths OH and FG OF the second target rectangle being equal to the sum OF the first main face relief corresponding to the first side OA and the depth OF the buildings arranged along the first side OA, and the widths OF and GH OF the second target rectangle being equal to the sum OF the second main face relief corresponding to the second side OB and the depth OF the buildings arranged along the second side OB.

In practical applications, in addition to using the vertices of the target included angle as the vertices of the first target rectangle and the second target rectangle, the vertices of the target included angle may also be used as other points on the long side of the first target rectangle and the long side of the second target rectangle. For example, when the length of the first target rectangle is set to be twice the sum of the second principal plane back-off distance and the depth of the buildings arranged along the second side, the vertex of the target angle may be taken as the midpoint of the long side of the first target rectangle, and when the length of the second target rectangle is set to be twice the sum of the first principal plane back-off distance and the depth of the buildings arranged along the first side, the vertex of the target angle may be taken as the midpoint of the long side of the second target rectangle.

It should be understood that, in practical applications, the relationship between the long side of the target rectangle and the sum of the main surface back-off distance and the building depth may be set according to actual requirements, and the manner of setting the long side of the target rectangle is not limited in any way herein.

In a second implementation, the electronic device may first determine a first reference edge according to buildings arranged along a first edge of the target angle, the first reference edge being parallel to the first edge, and determine a second reference edge according to buildings arranged along a second edge of the target angle, the second reference edge being parallel to the second edge; and then determining the included angle between the first reference edge and the second reference edge as a target reference included angle, wherein the target reference included angle is equal to the target included angle. Furthermore, the first target rectangle and the second target rectangle are drawn based on the first reference edge, the second reference edge and the vertex of the target reference included angle, specifically, the electronic device may determine the depth of the building arranged along the first edge as the width of the first target rectangle and the length of the second target rectangle, and determine the depth of the building arranged along the second edge as the length of the first target rectangle and the width of the second target rectangle; drawing a first target rectangle towards the inward direction of the target land parcel according to the length and the width of the first target rectangle by taking the vertex of the target reference included angle as one vertex of the first target rectangle and taking the first reference edge as the long edge of the first target rectangle; and drawing the second target rectangle towards the inward direction of the target land block according to the length and the width of the second target rectangle by taking the vertex of the target reference included angle as one vertex of the second target rectangle and taking the second reference edge as the long edge of the second target rectangle.

It should be noted that the first reference edge is substantially determined by points on the buildings arranged along the first edge that are nearest to the first edge, that is, the first reference edge is substantially a connection line of points on the buildings arranged along the first edge that are nearest to the first edge; similarly, the second reference edge is essentially a line connecting points on buildings located along the second edge that are closest to the second edge. Since the first reference edge is parallel to the second reference edge, the target reference angle between the first reference edge and the second reference edge is equal to the target angle.

In order to facilitate understanding of the drawing process of the first target rectangle and the second target rectangle, the drawing process is exemplarily described below with reference to fig. 3. As shown in FIG. 3, the vertex of the target angle is point O, the first side of the target angle is OA, and the second side of the target angle is OB; the first reference edge CD is determined according to the buildings arranged along the first edge OA, the second reference edge CE is determined according to the buildings arranged along the second edge OB, the first reference edge CD and the second reference edge CE are intersected at a point C, and the corresponding included angle at the point C is the target reference included angle; one long side CF of the first target rectangle CFGH lies on the first reference side CD, the lengths CF and GH of the first target rectangle being equal to the depth of the buildings arranged along the second side OB, the widths CH and FJ of the first target rectangle being equal to the depth of the buildings arranged along the first side OA; one long side CK of the second target rectangle CIJK is located on the second reference side CE, the lengths CK and IJ of the second target rectangle being equal to the depth of the buildings arranged along the first side OA, and the widths CI and KJ of the second target rectangle being equal to the depth of the buildings arranged along the second side OB.

It should be noted that, in practical applications, in addition to using the vertex of the target reference included angle as the vertex of the first target rectangle and the vertex of the second target rectangle, the vertex of the target reference included angle may also be used as another point on the long side of the first target rectangle and the long side of the second target rectangle. For example, when the length of the first target rectangle is set to be twice the depth of the buildings arranged along the second side, the vertex of the target reference angle may be taken as the midpoint of the long side of the first target rectangle, and when the length of the second target rectangle is set to be twice the depth of the buildings arranged along the first side, the vertex of the target reference angle may be taken as the midpoint of the long side of the second target rectangle.

It should be understood that, in practical application, the relationship between the long side of the target rectangle and the building depth may be set according to actual requirements, and the application does not limit the manner of setting the long side of the target rectangle.

It should be noted that the two implementation manners are only examples, and in practical applications, the electronic device may also use other manners to draw the first target rectangle and the second target rectangle, and the manner of drawing the first target rectangle and the second target rectangle by the electronic device is not limited in this application.

After the electronic equipment finishes drawing the first target rectangle and the second target rectangle, the overlapping area between the first target rectangle and the second target rectangle can be determined as an area where building shielding is likely to occur, namely the overlapping area between the first target rectangle and the second target rectangle is determined as a shielding area, and then buildings are prevented from being arranged in the shielding area.
