Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The communication pipeline has rich related resource contents, including pipeline resources, space resources, machine room equipment, optical cable resources, client resources, wireless equipment and the like. The diversity of resource contents determines that a communication pipeline construction site is not fixed at a certain place, and the construction area of the communication pipeline engineering is wide in range. In order to carry out whole-course supervision and acceptance on the actual progress and the engineering quality of the communication pipeline engineering in the construction process, operators generally adopt an engineering remote acceptance technology at present to carry out construction and acceptance along with the communication pipeline engineering so as to ensure that the process quality of the whole engineering meets the design requirements and avoid the situation of rework reconstruction during the final acceptance of the engineering.
Electronic fences play a critical role in the remote acceptance of communication pipeline engineering.
As shown in fig. 1, prior to remote acceptance of a target communication pipeline project, an engineer sends construction area information of the target communication pipeline to the server 12 through the design equipment 14. The server 12 determines a circular electronic fence of the target communication pipeline according to a preset radius by taking a position point in the construction area as a circle center. The server 12 configures the determined electronic fence into the acquisition application. The construction site personnel adopt the acquisition application program downloaded in advance on the mobile terminal 11 to acquire images of the area in the electronic fence, so as to obtain field image data. Generally, the acquisition application of the mobile terminal 11 can only acquire live images of the area inside the electronic fence, but cannot acquire live images of the area outside the electronic fence. Illustratively, the mobile terminal 11 may perform the on-site image capturing only when the mobile terminal is located in the geographic area defined by the electronic fence corresponding to the capturing application. If the position of the mobile terminal 11 is not within the geographic area defined by the electronic fence, the collection application on the mobile terminal 11 cannot operate normally or cannot perform field image collection. The mobile terminal 11 may be any mobile device having an image capturing function and a positioning function, such as a mobile phone, a notebook computer, a mobile camera, an internet of things device, and the like. The mobile terminal 11 sends the live image data to the server 12 associated with the collection application, and the server 12 sends the live image data to the display device 13 deployed at the acceptance site. The acceptance personnel remotely accept the target communication pipeline according to the field image data received by the display device 13.
The electronic fence of the target communication pipeline determined by the existing method is a circular electronic fence which is determined according to a preset radius and takes one position point of a construction site of the target communication pipeline as a circle center. The electronic fence often contains a construction area with multiple communication lines. For example, the electronic fence includes a construction area of other communication pipelines (e.g., communication pipeline 2 in fig. 1) in addition to a construction area of a target communication pipeline (e.g., communication pipeline 1 in fig. 1). Therefore, the field image data collected by the collecting application program based on the electronic fence not only includes the field image of the construction area of the target communication pipeline, but also includes the field images of the construction areas of other communication pipelines. When the acceptance personnel receive the site image data of the construction area containing a plurality of communication pipelines, the site image accurately matched with the construction site of the target communication pipeline is difficult to be accurately determined from the site image data, and then the target communication pipeline cannot be accurately accepted. Therefore, the area in the electronic fence determined by the existing method has the problem of poor matching with the actual construction area of the target communication pipeline, so that the field image data corresponding to the electronic fence has poor matching with the actual construction field of the target communication pipeline, and the remote acceptance of the target communication pipeline is adversely affected.
Usually, the communication pipelines are independent from each other, and each communication pipeline is constructed from point to line for a long distance. Therefore, if the construction path of the target communication pipeline is determined, and an electronic fence only matched with the construction path of the target communication pipeline is determined along the construction path of the target communication pipeline, the problem that the matching between the area in the electronic fence determined by the existing method and the actual construction area of the target communication pipeline is poor can be solved.
In view of the above, the present application provides a method for determining an electronic fence, which includes obtaining respective location information of a plurality of communication resource nodes on a target communication line; determining a construction path of a target communication pipeline based on the respective position information of the plurality of communication resource nodes; determining a buffer area of the construction path by taking the construction path as a line element and taking a first preset threshold value as a buffer distance; and determining the position information of the boundary of the buffer area as the position information of an electronic fence corresponding to the construction path, wherein the electronic fence is used for remote acceptance of the target communication pipeline. The construction path of the target communication pipeline is used as a line element, the buffer distance is a first preset threshold value, the buffer area of the construction path is determined, the electronic fence corresponding to the construction path is determined based on the buffer area, the situation that the construction areas of other communication pipelines are brought into the electronic fence of the target communication pipeline is avoided, the situation image data collected in the electronic fence corresponding to the construction path of the target communication pipeline is ensured, the situation image data are accurately matched with the actual construction area (or the actual construction site) of the target communication pipeline, and the problem that the matching performance of the area in the electronic fence determined by the existing method and the actual construction area of the target communication pipeline is poor is solved.
The electronic fence determination method provided by the present application is described below with reference to some embodiments.
Fig. 2 is a diagram of a remote acceptance scenario of communication pipeline engineering according to an embodiment of the present application. As shown in fig. 2, the job site personnel download the acceptance application on the mobile terminal 11 in advance. The construction site personnel sends an authentication request to the background equipment 21 associated with the acceptance application program through the acceptance application program on the mobile terminal 11. The authentication request includes an identification of the target communication pipe and an acceptance period. The background device 21 performs authentication based on the authentication request. After the authentication is passed, the background device 21 configures the electronic fence of the target communication pipeline for the acceptance application program on the mobile terminal 11. Optionally, the configured valid time period of the electronic fence is an acceptance time period. And (3) the construction site personnel adopt an acceptance application program on the mobile terminal 11 in an acceptance time period to carry out on-site image acquisition on the geographical area limited by the electronic fence configured by the program so as to obtain on-site images of the target communication pipeline. The acceptance application of the mobile terminal 11 can only collect live images of the area inside the electronic fence configured for the application, but cannot collect live images of the area outside the electronic fence. Specifically, the acceptance application program can normally collect the live image only when the mobile terminal 11 is located in the electronic fence corresponding to the acceptance application program, or only when the mobile terminal 11 is located in the geographic area defined by the electronic fence corresponding to the acceptance application program. If the position of the mobile terminal 11 is not in the electronic fence, the acceptance application program cannot run normally or cannot collect the field image. The mobile terminal 11 may be any mobile device with image capturing and positioning functions, such as a mobile phone, a notebook computer, a mobile camera, an internet of things device, and the like. The mobile terminal 11 sends the live image collected by the acceptance application to the background device 21 associated with the acceptance application, and the background device 21 sends the live image to the display device 13 deployed on the acceptance site. The acceptance personnel remotely accept the target communication pipeline project based on the live image received by the display device 13.
Wherein, the electronic fence of the target communication pipeline may be determined by the background device 21 as follows: the background device 21 obtains the respective location information of the plurality of communication resource nodes on the target communication pipeline from the design device 14 corresponding to the target communication pipeline. The communication resource node may be a location point where equipment in a computer room is deployed on a communication pipeline or other communication resource construction points. The location Information may be location Information based on a Geographic Information Science (GIS) map. The background device 21 determines a construction path of the target communication pipeline based on the respective location information of the plurality of communication resource nodes. The background device 21 determines a buffer area of the construction path by using the construction path of the target communication pipeline as a line element and using a first preset threshold as a buffer distance. As shown in fig. 2, the buffer zone is a band-shaped area surrounding the construction path. The background equipment 21 determines that the position information of the boundary of the buffer area is the position information of the electronic fence corresponding to the construction path. The electronic fence is used for remote acceptance of the target communication pipeline. And the electronic fence corresponding to the construction path is the electronic fence of the target communication pipeline. Alternatively, the designing device 14 may also design and determine a construction path of the target communication pipeline based on the respective location information of the plurality of communication resource nodes on the target communication pipeline, and then send the construction path to the background device 21. The background device 21 determines a buffer area of the construction path by using the received construction path of the target communication pipeline as a line element and using a first preset threshold as a buffer distance, and determines position information of a boundary of the buffer area as position information of the electronic fence corresponding to the construction path of the target communication pipeline.
Optionally, the background device 21 determines the buffer area of the construction path by using the construction path of the target communication pipeline as a line element and using a first preset threshold as a buffer distance, where the buffer area of the construction path may be determined by using a line buffer area algorithm in the spatial analysis of the vector data and using the first preset threshold as the buffer distance by the background device 21. Alternatively, the line buffer algorithm may be an angular bisector method or a convex arc method.
According to the electronic fence determining method, the construction path of the target communication pipeline is used as a line element, the first preset threshold value is used as the buffer distance, the buffer area of the construction path is determined, the position information of the boundary of the buffer area is determined to be the position information of the electronic fence corresponding to the construction path, the electronic fence matched with the construction path of the target communication pipeline is obtained, the problem that the matching between the construction areas of other communication pipelines and the actual construction area of the target communication pipeline is poor due to the fact that the field images collected in the electronic fence of the target communication pipeline are the field images accurately matched with the actual field of the target communication pipeline, and the problem that the matching between the areas in the electronics determined by the existing method and the actual construction area of the target communication pipeline is poor is solved, and rail inspection personnel are guaranteed to accurately inspect the target communication pipeline project based on the collected field images.
The following describes the determination method of the electronic fence provided by the present application in detail with reference to fig. 2, fig. 3, fig. 4, and fig. 5.
Fig. 3 is a flowchart of an electronic fence determining method according to an embodiment of the present application. Fig. 4 is a first schematic view of an electronic fence according to an embodiment of the present application. Fig. 5 is a second schematic view of an electronic fence according to an embodiment of the present application. The execution subject of the embodiment shown in fig. 3 is the background device 21 in the embodiment shown in fig. 2. As shown in fig. 3, the method includes:
s101, obtaining the position information of each of a plurality of communication resource nodes on a target communication pipeline.
Specifically, the backend device 21 acquires the respective location information of the plurality of communication resource nodes on the target communication pipeline. Illustratively, the background device 21 obtains the respective location information of the multiple communication resource nodes on the target communication pipeline from the design device 14 corresponding to the target communication pipeline. Alternatively, the background device 21 may also obtain the respective location information of the plurality of communication resource nodes on the target communication pipeline from other devices storing the communication resource nodes of the target communication pipeline.
The communication resource nodes on the target communication pipeline are 1 st node, 2 nd node, 3 rd node, 4 th node, 5 th node, 6 th node, 7 th node and 8 th node shown in fig. 4 or fig. 5.
S102, determining a construction path of a target communication pipeline based on the position information of each of the plurality of communication resource nodes.
Specifically, the background device 21 determines the construction path of the target communication pipeline based on the position information of each of the plurality of communication resource nodes.
Optionally, the background device 21 connects the plurality of communication resource nodes of the target communication pipeline in sequence according to the communication direction to obtain the construction path of the target communication pipeline.
For example, assume that the target communication pipe communication direction order is: the 1 st node, the 2 nd node, the 3 rd node, the 4 th node, the 5 th node, the 6 th node, the 7 th node and the 8 th node. The background device 21 sequentially connects the 1 st node, the 2 nd node, the 3 rd node, the 4 th node, the 5 th node, the 6 th node, the 7 th node, and the 8 th node to obtain the construction path of the target communication pipeline as shown in fig. 4.
Optionally, if the number of the communication resource nodes on the target communication pipeline exceeds two, the background device 21 sorts the plurality of communication resource nodes of the target communication pipeline according to the communication direction to obtain a node sequence. The background device 21 determines whether the mth communication resource node, the (m-1) th communication resource node and the (m + 1) th communication resource node in the node sequence are collinear based on the position information; if not, the background device 21 determines that the mth communication resource node is the break point of the target communication pipeline. The background device 21 determines a construction path of the target communication pipeline based on the respective position information of the first communication resource node, the determined break point, and the last communication resource node in the node sequence. Wherein m is more than or equal to 2 and is a natural number. The first communication resource node and the last communication resource node are end points of the construction path.
Illustratively, the background device 21 sequentially connects the first communication resource node, the determined break point, and the last communication resource node to obtain the construction path of the target communication pipeline. Preferably, the first communication resource node, the determined break point and the last communication resource node are characteristic points of the construction path. The connecting line of two adjacent characteristic points is a straight line.
For example, if the background device 21 determines that the 2 nd node, the 4 th node, the 5 th node, and the 6 th node are break points in the plurality of communication resource nodes of the target communication pipeline, the background device 21 sequentially connects the first communication resource node (e.g., the 1 st node), the determined break points (e.g., the 2 nd node, the 4 th node, the 5 th node, and the 6 th node), and the last communication resource node (e.g., the 8 th node), to obtain the construction path of the target communication pipeline as shown in fig. 5.
The straight line between two points is the shortest, and during the construction process of the communication pipeline, a plurality of communication resource nodes which can be collinear are usually deployed on a straight line type communication pipeline, so that on one hand, communication resources such as optical/electric cables can be saved, and on the other hand, the construction is more convenient. Therefore, before the construction path of the target communication pipeline is determined, the non-collinear break points are determined from the plurality of communication resource nodes, the construction path of the target communication pipeline is determined based on the break points and the position information of the first and last communication resource nodes, and the accuracy of the determined construction path is ensured.
For example, the background device 21 may determine whether the mth communication resource node in the node sequence is collinear with the (m-1) th communication resource node and the (m + 1) th communication resource node based on the location information in the manner shown in steps S1021-S1022:
s1021, based on the position information of the (m-1) th communication resource node and the (m + 1) th communication resource node, the background device 21 determines a first common line connecting the (m-1) th communication resource node and the (m + 1) th communication resource node.
S1022, if the background device 21 determines that the vertical distance from the mth communication resource node to the first collinear line is less than or equal to the second preset threshold, it determines that the mth communication resource node is collinear with the (m-1) th and (m + 1) th communication resource nodes.
S103, determining a buffer area of the construction path by taking the construction path as a line element and taking a first preset threshold value as a buffer distance.
Illustratively, the background device 21 determines a buffer area of the construction path by taking the construction path as a line element and taking a first preset threshold R as a buffer distance.
As shown in fig. 4 and 5, the buffer zone is a band-shaped area surrounding the construction path.
Optionally, the first communication resource node, the determined break point, and the last communication resource node in the node sequence are feature points of the construction path. The background device 21 may determine the buffer area of the construction path by using the construction path as a line element and using the first preset threshold R as a buffer distance in the following manner shown in steps S1031 to S1035:
and S1031, the background equipment 21 determines an equidistant line of which the vertical distance from a connecting line of two adjacent characteristic points on the construction path is equal to a first preset threshold value.
Preferably, a connecting line of two adjacent characteristic points on the construction path is a straight line, and an equidistant line, the vertical distance of which from the connecting line of two adjacent characteristic points on the construction path is equal to the first preset threshold R, is a parallel line of the connecting line.
S1032, the background equipment 21 determines that the intersection point of two adjacent equidistant lines on the same side of the construction path is a first intersection point.
S1033, the background device 21 determines a circular buffer area corresponding to the end point of the construction path by taking the end point of the construction path as a circle center and taking the first preset threshold R as a radius.
S1034 and the background device 21 determines that the intersection point of the circular buffer and the equidistant line is the second intersection point.
S1035, the back-end device 21 determines the buffer area of the construction path based on the position information of the first intersection point and the second intersection point.
For example, the background device 21 forms a closed loop by using a connection line of two second intersection points adjacent to the same end point of the construction path, a connection line of the second intersection point and an adjacent first intersection point, and a connection line of two adjacent first intersection points on the same side of the construction path. The back-office equipment 21 determines the area defined within the closed loop to be a buffer of the construction path. The buffer area of the construction path formed by the connection line of two adjacent second intersection points at the same end point, the connection line of the second intersection point and the adjacent first intersection point, and the connection line of two adjacent first intersection points at the same side of the construction path is shown in fig. 4.
Optionally, the first intersection point and the second intersection point are boundary points of the buffer. The backend device 21 may determine the buffer area of the construction path based on the position information of the first intersection point and the second intersection point in the manner shown in steps S1036 to S1038 as follows:
s1036, the background device 21 determines a circular line with the end point of the construction path as the center of the circle and the first preset threshold as the radius.
S1037, the background equipment 21 sequentially connects the boundary points on the same side of the construction path according to the communication direction to obtain a first boundary line.
S1038, the background device 21 determines that the maximum closed loop area formed by the first boundary line and the circumferential line is a buffer area of the construction path.
Further, after the back-end device 21 determines that the maximum closed-loop area formed by the first boundary line and the circumferential line is the buffer area of the construction path, the back-end device 21 determines whether the first intersection point is a salient point. If yes, the backend device 21 adopts an arc with a radius equal to the first preset threshold R to perform arc closure on the first boundary line at the salient point, so as to obtain a buffer area with a closed boundary arc, as shown in fig. 5. The boundary of the buffer zone at the intersection of the circular arcs is shown in fig. 5.
In the work progress of communication pipeline, for being under construction, the bump contained angle adopts circular arc transition construction mode usually, consequently, in this application, carries out the circular arc with the bump department border of buffer area and closes, has ensured the agreeable with of buffer area with the actual construction sight, has improved follow-up definite fence's based on the buffer area precision.
Exemplarily, the background device 21 may determine the first intersection point P as follows i Whether the bump is present: the background device 21 follows the formula α = (x) in a preset coordinate system i -x i-1 )(y i+1 -y i )-(x i+1 -x i )(y i -y i-1 ) Determining a first intersection point P i The value of unevenness α.

S104, the background equipment 21 determines the position information of the boundary of the buffer area as the position information of the electronic fence corresponding to the construction path; the electronic fence is used for remote acceptance of the target communication pipeline.
Specifically, the background device 21 determines that the position information of the buffer boundary is the position information of the electronic fence corresponding to the construction path. And the electronic fence corresponding to the construction path is the electronic fence of the target communication pipeline. The electronic fence is used for remote acceptance of a target communication pipeline. The buffer area is an area defined by the electronic fence corresponding to the construction path.
Illustratively, the background device 21 determines the position information of the buffer boundary on the GIS map as the position information of the electronic fence corresponding to the construction path. Based on the position information of the electronic fence, the background equipment configures the electronic fence of the target communication pipeline on a GIS map associated with the acceptance application program.
For example, after the background device 21 determines that the location information of the buffer boundary is the location information of the electronic fence corresponding to the construction path, the background device 21 may respond to the authentication request sent by the mobile terminal 11, and configure the electronic fence of the target communication pipeline for the acceptance application on the mobile terminal 11 based on the location information of the electronic fence after the authentication is passed.
The electronic fence determination method provided by the present application is described below with specific examples.
Example one, as shown in fig. 2 and 5, assume that there are multiple communication resource nodes on the target communication pipeline. Background device 21 may determine the electronic fence of the target communication pipeline as follows in steps (1) - (8).
(1) The background device 21 acquires the position information of each of the plurality of communication resource nodes of the target communication pipeline from the design device 14. The location Information may be location Information based on a Geographic Information Science (GIS) map, such as location Information expressed in longitude and latitude.
The background device 21 performs the subsequent steps (2) - (8) based on the GIS map.
(2) The background device 21 sorts the acquired multiple communication resource nodes according to the communication direction to obtain a node sequence: [ 1 st node, 2 nd node, 3 rd node, 4 th node, 5 th node, 6 th node, 7 th node, 8 th node ].
The background device 21 determines whether three adjacent nodes in the node sequence are collinear or not based on the position information of each communication resource node. Specifically, the background device 21 determines whether the 2 nd node is collinear with the 1 st node and the 3 rd node according to steps S1021-S1022, and if it is determined that the 2 nd node is not collinear with the 1 st node and the 3 rd node, it is determined that the 2 nd node is a break point. Similarly, the background device 21 determines whether the 3 rd node is collinear with the 2 nd node and the 4 th node according to steps S1021-S1022, and if the 3 rd node is determined to be collinear with the 2 nd node and the 4 th node, it is determined that the 3 rd node is not a break point. Similarly, the background device 21 determines whether the 4 th node is collinear with the 3 rd node and the 5 th node according to steps S1021-S1022, and determines that the 4 th node is a break point if it is determined that the 4 th node is not collinear with the 3 rd node and the 5 th node. Similarly, the background device 21 determines whether the 5 th node is collinear with the 4 th node and the 6 th node according to steps S1021-S1022, and if the 5 th node is determined not to be collinear with the 4 th node and the 6 th node, the 5 th node is determined to be a break point. Similarly, the background device 21 determines whether the 6 th node is collinear with the 5 th node and the 7 th node according to steps S1021-S1022, and if it is determined that the 6 th node is not collinear with the 5 th node and the 7 th node, it is determined that the 6 th node is a break point. Similarly, the background device 21 determines whether the 7 th node is collinear with the 6 th node and the 8 th node in steps S1021-S1022, and if it is determined that the 7 th node is collinear with the 6 th node and the 8 th node, it is determined that the 7 th node is not a break point. Thus, the background device 21 determines that the 2 nd node, the 4 th node, the 5 th node, and the 6 th node are all break points.
(3) The background device 21 sequentially connects the first communication resource node (i.e., the 1 st node), the determined break points (i.e., the 2 nd node, the 4 th node, the 5 th node, and the 6 th node), and the last communication resource node (i.e., the 8 th node), to obtain the construction path of the target communication pipeline as shown in fig. 5. The background device 21 determines that the 1 st node, the 2 nd node, the 4 th node, the 5 th node, the 6 th node and the 8 th node are feature points of the construction path.
(4) And the background equipment 21 determines an equidistant line of which the vertical distance from a connecting line of two adjacent characteristic points on the construction path is equal to a first preset threshold value R. The connecting line of two adjacent characteristic points on the construction path is a straight line.
The background equipment 21 determines that the intersection point of two adjacent equidistant lines on the same side of the construction path is a first intersection point.
(5) And the background equipment 21 determines a circular buffer area corresponding to the construction path end point by taking the construction path end point as a circle center and taking the first preset threshold value as a radius.
The backend device 21 determines the intersection of the circular buffer and the equidistant line as a second intersection.
(6) And the background device 21 determines the first intersection point and the second intersection point as boundary points of the buffer area.
The background device 21 determines a circumferential line corresponding to the construction path end point by taking the construction path end point (i.e., the 1 st node and the 8 th node) as a circle center and taking a first preset threshold as a radius.
The background device 21 connects the boundary points on the same side of the construction path in sequence according to the communication direction to obtain a first boundary line.
(7) And the background equipment 21 determines the maximum closed loop area formed by the first boundary line and the circumferential line as a buffer area of the construction path.
(8) The background device 21 determines whether the first intersection is a bump in the manner shown in step S103. If yes, the backend device 21 adopts an arc with a radius equal to the first preset threshold R to perform arc closure on the first boundary line at the salient point, so as to obtain a buffer area with a closed boundary arc as shown in fig. 5.
The background equipment 21 determines that the buffer area which is closed by the boundary arc is the area which is limited by the electronic fence corresponding to the construction path of the target communication pipeline. The background device 21 determines that the position information of the buffer zone boundary closed by the boundary arc is the position information of the electronic fence corresponding to the target communication pipeline construction path.
Example two, as shown in fig. 2, assume that there are only 1 communication resource node, such as the 1 st node, on the target communication pipeline. The background device 21 acquires the location information of the communication resource node of the target communication pipeline, i.e., the location information of the 1 st node, from the design device 14. The background device 21 determines a buffer area by taking the 1 st node as a circle center and the first preset threshold R as a radius. The background device 21 determines that the position information of the buffer boundary is the position information of the electronic fence corresponding to the target communication pipeline.
Example three, as shown in fig. 2, assume that there are 2 communication resource nodes, such as the 1 st node and the 2 nd node, on the target communication pipeline. The background device 21 acquires the position information of the communication resource node of the target communication pipeline, i.e., the position information of each of the 1 st node and the 2 nd node, from the design device 14. The background equipment 21 determines that the connection line of the 1 st node and the 2 nd node is a construction path of the target communication pipeline. The background device 21 determines a circumferential line with the end points (i.e., the 1 st node and the 2 nd node) of the construction path as a center and the first preset threshold R as a radius. The background equipment 21 determines an equidistant line at a vertical distance R from the construction path. The background equipment 21 determines the maximum closed loop area formed by the circumferential line and the equidistant line as a buffer area of the construction path. Background device 21 determines the location information of the buffer boundary as the location information of the electronic fence of the target communication pipeline.
Example four, as shown in fig. 2, assume that the number of communication resource nodes on the target communication line exceeds 2. After the background device 21 determines the construction path of the target communication pipeline according to the steps (1) to (3) in the example one, the background device 21 may determine the buffer area of the connection line between two adjacent feature points in a similar manner as in the example three. And the background device 21 adopts a superposition algorithm to superpose the determined buffer areas to obtain an area limited by the electronic fence of the target communication pipeline. Further, the background device 21 determines whether an intersection point of two adjacent equidistant lines on the same side of the construction path is a concave point, and if so, replaces an arc boundary adjacent to the intersection point with an included angle boundary where the intersection point is located.
