Technical Field

[0002] The land parcel sketch is the original record in the cadastral data. The land parcel sketch provides a basis for the maintenance, restoration and resolution of ownership disputes of the boundary points. The land parcel sketch can be used in conjunction with the cadastral survey form to provide important information for determining the coordinates of the boundary points and making the land parcel sketch. The land parcel sketch is an important drawing to check the geometric relationship of each parcel in the cadastral map and ensure the quality of the cadastral map.

[0003] The land parcel sketch should indicate the land parcel number and house number, the land parcel number and house number of the adjacent land parcel; the name of the user of the land parcel and the name of the user of the adjacent land parcel; the boundary points of the land parcel, the boundary point numbers and boundary lines; the length of the boundary sides, the distance between the boundary points and the adjacent features, and the length of the building sides, etc. In real estate registration and certification, it is necessary to obtain the distance between the land parcel and the adjacent land parcel. Traditionally, the distance is measured by manually pulling the boundary points using CAD or CASS software. This is a large workload with low efficiency. It is also easy to make mistakes due to human factors, which greatly affects the efficiency of real estate registration and certification. Summary of the invention

[0037] In order to make the purpose, 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 in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention.

[0038] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0039] Reference Figure 1 As shown, an embodiment of the present invention provides a method for automatically identifying the spacing of a plot sketch, comprising the following steps:

[0040] S1, obtaining the sketch data information of the plot, and obtaining the plot and multiple neighboring plots;

[0041] S2, acquiring the boundary points of the current plot and the adjacent plot, and obtaining the boundary points of the current plot and the boundary points of the adjacent plot;

[0042] S3, connecting the boundary point of the current plot of land with the boundary point of the adjacent plot of land to obtain a distance line between the boundary points of the current plot of land and the adjacent plot of land;

[0043] S4, among the spacing lines, obtain the shortest one or two shortest spacing lines on each boundary point of the land parcel.

[0044] Specifically, in the actual operation of this embodiment, a plot of land is confirmed in the plot sketch data, and there will be multiple neighboring plots around the plot of land. The distance lines between the plot of land and the neighboring plots, as well as the lengths of the distance lines, can be obtained through the method in the embodiment of the present invention. As described above, through the method provided by the present invention, the shortest or two shortest distance lines on each boundary point of the plot of land can be obtained. For the plot of land, there can be one or more neighboring plots. When there is one neighboring plot of land, only one distance line is retained on the boundary point of the plot of land, that is, the shortest distance line. When there are multiple neighboring plots of land, the boundary point of the plot of land needs to be measured with at most two neighboring plots, that is, the two shortest distance lines are retained on the boundary point of the plot of land. At the same time, the shortest distance line on the boundary point of the neighboring plot can be obtained. For the boundary points of adjacent plots, there will only be a spacing line between the adjacent boundary points of the own plot, that is, only one shortest spacing line is retained on each boundary point of the adjacent plot, and this shortest spacing line represents the spacing line between the adjacent plot and the own plot.

[0045] Furthermore, in the step S1, obtaining the land parcel sketch data information includes:

[0046] The graphic lines in the plot sketch data information are physically encoded to obtain JMD physical lines, non-JMD physical lines and non-physical lines.

[0047] Specifically, the JMD entity line includes general house lines, simple house lines, concrete house lines, and ground building lines such as proportional walls; the non-JMD entity lines are entity lines such as road lines and other non-buildings; the non-physical lines are lines such as floating balconies. In the process of obtaining the data information of the plot sketch, the graphic lines in the plot sketch are encoded. In this embodiment, the encoding adopts the encoding rules of the standard CASS encoding comparison table to obtain which is the JMD entity line, non-JMD entity line, and non-physical line (JMD is the abbreviation of residential area). Among them, the general house code is 141101, the simple house code is 141200, the concrete house code is 141111, and the proportional wall code is 144301. By determining the encoding attributes of each graphic line, setting the conditions for the spacing line to pass through and not to pass through, it is obtained which coding line graphic line the spacing line can pass through, and finally the spacing line that meets the regulations is obtained.

[0048] Furthermore, in step S2, the boundary point of the adjacent plot is a boundary point located at the vertex of the positive angle of the adjacent plot.

[0049] Specifically, boundary points are used to determine the location of property boundaries in cadastral surveying, and the lines connecting the boundary points constitute boundary lines. Boundary points are characteristic points on property boundary lines, and the scope and location of houses and their land use are determined by boundary points. Since only the spacing lines that meet the regulations between the current plot and the adjacent plot need to be obtained, the most accurate spacing between the current plot and the adjacent plot can be obtained. Therefore, this embodiment only considers the boundary points located at the vertices of the positive angles in the adjacent plots, so as to obtain the shortest spacing lines between the current plot and the adjacent plots. Since the spacing line between the boundary points located at the negative angles and the current plot is not the shortest spacing line, only the boundary points located at the vertices of the positive angles on the adjacent plots are required.

[0050] Furthermore, in step S3, the step of obtaining the distance line between the boundary points of the current plot and the adjacent plot includes:

[0051] Automatically remove the spacing line intersecting the current plot and the adjacent plot;

[0052] Automatically remove the longer of two intersecting spacing lines;

[0053] Automatically remove the spacing line between the current plot and the adjacent plot that is less than 0.1m apart;

[0054] The spacing lines whose angles with the boundary lines of the land parcel are less than 30 degrees are automatically removed, and finally the spacing lines between the boundary points of the land parcel and the adjacent land parcel are obtained.

[0055] Specifically, there may be many spacing lines between the boundary points of the current plot and the boundary points of the adjacent plot, but not all of them are spacing lines that meet the requirements. Each boundary point of the current plot can be connected to each boundary point of the adjacent plot to form a spacing line. Therefore, in the specific operation process, this embodiment sets conditions for the spacing lines and retains the spacing lines that meet the requirements.

[0056] When the spacing point connection line between the current plot and the adjacent plot intersects the ownership area of ​​the current plot or the adjacent plot, that is, when the spacing connection line intersects the JMD entity line, the spacing connection line does not meet the requirements and needs to be removed;

[0057] There are many intersecting spacing lines between the current plot and the adjacent plot. For the intersecting spacing lines, the longer one of every two intersecting spacing lines needs to be removed, and the shorter one needs to be retained, so as to be more conducive to obtaining the shortest spacing line between the current plot and the adjacent plot.

[0058] When the neighboring plot is directly adjacent to the current plot, there is no need to obtain the spacing line, and the length of the spacing line is 0; if the length of the spacing line between the current plot and the neighboring plot is less than 0.1m, the spacing line with a length less than 0.1m is removed;

[0059] When the angle between the spacing line and the boundary line of the land parcel is less than 30 degrees, it indicates that this spacing line is not the shortest and optimal spacing line and should be removed.

[0060] Preferably, in this embodiment, each of the above conditions for automatically removing the connection lines that do not meet the specified spacing is in parallel rather than in priority order, and the above automatic removal conditions must be met at the same time in order to obtain the shortest spacing connection line.

[0061] Furthermore, after step S4, the method further includes:

[0062] S5, if the spacing line does not intersect any JMD solid line, non-JMD solid line and non-solid line, then output the length of the spacing line; if the spacing line intersects the non-JMD solid line and the non-solid line, then output the length of the spacing line.

[0063] Specifically, when the boundary points between the current plot and the adjacent plot are connected to form a spacing line, there may be non-JMD solid lines and non-solid lines, as well as JMD solid lines such as walls between the current plot and the adjacent plot. As can be seen from the above, the graphic lines have been encoded, and based on the encoded line information, the graphic lines that the spacing lines can pass through and the graphic lines that cannot be passed through can be obtained. In this embodiment, non-JMD solid lines and non-solid lines do not affect the determination of the spacing lines, and the spacing lines are allowed to intersect with non-JMD solid lines and non-solid lines, thereby obtaining the spacing lines between the current plot and the adjacent plot. The length accuracy of the spacing lines obtained in this embodiment is 0.01m. If there are JMD solid lines such as walls between the current plot and the adjacent plot, the spacing lines will not be generated and the distance will not be output.

[0064] As a case of this embodiment, Figure 2 As shown in the figure, with "Hemei Village Shanqing Hall" as the main plot, the boundary point J4 of this plot can pass through the dotted line of the neighboring plot in the figure, that is, the balcony line, which is a non-solid line. There are two spacing lines at the location of the boundary point J4, which are connected to two adjacent neighboring plots respectively, indicating the spacing between the two neighboring plots. Similarly, if Figure 3 As shown, "Lü Rijin" in the black box is the main plot, the boundary point J4 is connected to the boundary point of the adjacent plot, and passes through the balcony line, and the specific length is displayed on this spacing line.

[0065] As a case of this embodiment, Figure 4 As shown, "Lü Rishi" in the black box is the main plot, and the boundary point J13 of the main plot crosses the road line, where the road line is a non-JMD entity line. The boundary point on the boundary point J13 can cross the road line and connect with the boundary point of the adjacent plot, and the length of the spacing line is displayed.

[0066] As a case of this embodiment, Figure 5 As shown, "Lü Xueche" in the black box is the main plot, and there is a JMD entity line between the boundary point J3 and the adjacent plot. In this case, no spacing line is generated and no spacing is output.

[0067] like Figure 6 As shown, "Lv Binyan" in the black box is the main plot. There is a JMD entity line between the boundary point J5 and the adjacent plot, that is, the wall line opposite the boundary point J5. At this time, no spacing line is generated and no spacing is output.
