Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a method and system for quickly acquiring coordinates and areas based on map applications. Background Art

[0002] In many aspects of geographic surveying and mapping, it is necessary to calculate the land area of ​​the map, and the results of the area calculation are applied to land planning, infrastructure construction, etc. This greatly reduces the workload of actual land field surveys, saves labor costs, and improves surveying and mapping efficiency. In the prior art, computers are used to draw map polygonal areas and calculate areas, but their operations are complicated and the measurement accuracy is low.

[0003] More information related to the above technical solution can also be found in the following documents:

[0004] For example, a method and system for drawing and calculating the area of ​​a map polygonal area disclosed in Chinese patent publication number CN 112767517 A specifically discloses a method for drawing and calculating the area of ​​a map polygonal area, which is implemented by the following steps: step 1, loading the map and initializing; step 2, defining the longitude and latitude of the mouse click point; step 3, instantiating the polygon editor; step 4, drawing a polygon by clicking the mouse point; step 5, calculating the actual land area corresponding to the polygonal area; step 6, constructing an information window to prompt the polygonal area geographic information.

[0005] In the process of implementing the present invention, the inventors found that the prior art has the following problems:

[0006] The existing methods of drawing polygonal areas and calculating areas on maps can only use polygons to draw the target area. During use, the shape that actually needs to be measured is generally a complex graphic, and multiple marking points need to be clicked in sequence. After clicking the wrong marking point, the boundary cannot be adjusted and needs to be redrawn, resulting in complicated operations and low measurement accuracy. Summary of the invention

[0007] To this end, it is necessary to provide a method and system for quickly obtaining coordinates and areas based on map applications, so as to solve the technical problems in the prior art that multiple marking points need to be clicked in sequence, and after clicking the wrong marking point, the boundary cannot be adjusted and needs to be redrawn, resulting in complicated operation and low measurement accuracy.

[0008] To achieve the above object, the inventor provides a method for quickly obtaining coordinates and areas based on a map application, comprising the following steps:

[0009] Install the plug-in and map application on the terminal respectively, and open the map application and plug-in;

[0010] Search the location whose coordinates and area you need to obtain on the map application and find the location that needs to be measured;

[0011] Click the Start Drawing button to draw the outline. Draw the first point, the second point, and the third point on the map until the outline is closed. Then the drawing ends.

[0012] When drawing the second point, the midpoint between the first and second points is automatically generated. When drawing the third point, the midpoint between the second and third points is automatically generated, and so on.

[0013] After drawing, you can drag the boundary points to modify the outline. The boundary points include the first point, second point, third point to Nth point drawn actively, and the automatically generated midpoint.

[0014] After completing the modification of the outline, click the Save button to complete the drawing of the outline, calculate the actual coordinates and area corresponding to the outline area, and display the actual coordinates and area of ​​the location to be measured.

[0015] Different from the prior art, the above technical solution automatically generates the midpoint between the first point and the second point when drawing the second point, and automatically generates the midpoint between the second point and the third point when drawing the third point, and so on; after drawing, the boundary points can be dragged to modify the contour, and the boundary points include the first point, the second point, the third point to the Nth point drawn actively, and the automatically generated midpoint; after completing the modification of the contour, click the Save button to complete the drawing of the contour, calculate the actual coordinates and area corresponding to the contour area, and display the actual coordinates and area of ​​the location to be measured. In this way, the midpoint can be automatically generated during the drawing process, and after the drawing is completed, the drawing point and the automatically generated midpoint can be dragged to refine the drawn contour, and the drawn boundary can be easily adjusted. The operation is simple, the contour edge can be refined, and the measurement accuracy can be effectively improved.

[0016] As an embodiment of the present invention, in the step of dragging the boundary points to modify the contour:

[0017] When you drag an automatically generated midpoint, a midpoint between two points connected to the midpoint is automatically generated.

[0018] In this way, you can achieve infinite subdivision by dragging the automatically generated midpoint, further adjust the contour edge, and continuously nest it to improve the measurement precision.

[0019] As an implementation mode of the present invention, the first point, the second point, the third point to the Nth point actively drawn by the operator on the map are marked with large dots, and the automatically generated midpoint is marked with a small dot;

[0020] In the step where the operator drags the boundary points to modify the contour, when the operator drags the automatically generated midpoint, the midpoint becomes a large dot mark, and the two automatically generated midpoints thereafter are marked with small dots.

[0021] In this way, the identification points can be distinguished. The automatically generated midpoints are marked with small dots. The large dots can be dragged, but no midpoints are generated. After the small dots are dragged, they are automatically converted into large dots, thereby generating two midpoints, which is convenient for adjusting the boundaries of the contour and improves the controllability of the adjustment.

[0022] As an implementation mode of the present invention, in the step of dragging the boundary points to modify the outline, the map can be zoomed in, zoomed out, and the interface display position can be moved.

[0023] In this way, the map can be zoomed in, zoomed out, and the interface display position can be moved, making it easy to adjust the boundaries of the outline.

[0024] As an implementation mode of the present invention, after drawing the first point, the second point, and the third point on the map, it is necessary to click the first point again so that the outline thereof will be closed.

[0025] In this way, you can click the first point at any time to complete the closed selection of the contour, making it easier for the operator to select the area range.

[0026] As an embodiment of the present invention, after completing the step of modifying the profile, the following steps are also included:

[0027] Click the Auto-adjust Boundary button to adjust the boundary of the outline. After the adjustment is completed, click the Save button.

[0028] In this way, you can use the automatic boundary adjustment button to make fine adjustments to the outline boundary, which can effectively improve the accuracy of the edge.

[0029] As an implementation manner of the present invention, adjusting the boundary of the contour specifically includes the following steps:

[0030] The display interface of the terminal at this time is intercepted, and the graphics within the boundary of the contour and the graphics outside the boundary of the contour are analyzed by an image recognition method;

[0031] When the color similarity between the graphics within the boundary of the contour and the graphics outside the boundary of the contour is greater than a preset value, the preset range outside the boundary of the contour is included in the boundary of the contour.

[0032] In this way, by comparing the color similarity between the graphics within the boundary of the outline and the graphics outside the boundary of the outline, the graphics outside the boundary can be included in the outline within a preset range without manual adjustment, thereby improving the adjustment speed.

[0033] As an implementation of the present invention, when the color similarity between a graphic within a preset range within the boundary of the contour and a graphic at the center point within the contour is less than a preset value, the graphic within the preset range within the boundary is included outside the boundary of the contour.

[0034] In this way, the color similarity between the graphics within the preset range of the boundary and the graphics at the center point of the boundary can exclude the preset range of the boundary without manual adjustment, thereby improving the adjustment speed.

[0035] As an implementation mode of the present invention, it also includes an automatic adjustment return button. When the automatic adjustment boundary button is clicked, the boundary of the contour is adjusted. After the adjustment is completed, the automatic adjustment return button can be clicked to return to the original boundary of the contour.

[0036] In this way, the automatic adjustment return button can be used. When the adjustment does not conform to the actual situation, it can return to the original state and perform manual adjustment, which is convenient for the operator.

[0037] To achieve the above objectives, the inventors also provide a system for quickly acquiring coordinates and areas based on a map application, including a method for quickly acquiring coordinates and areas based on a map application as described in any one of the methods provided by the above inventors.

[0038] Different from the prior art, the system of the above technical solution can automatically generate midpoints during the drawing process. After the drawing is completed, the drawing points and the automatically generated midpoints can be dragged to refine the drawn contour, and the drawn boundaries can be easily adjusted. The operation is simple, the contour edges can be refined, and the measurement accuracy can be effectively improved.

[0058] In many aspects of geographic surveying and mapping, it is necessary to calculate the land area of ​​the map, and apply the results of the area calculation to land planning, infrastructure construction, etc. This greatly reduces the workload of actual land site surveys, saves labor costs, and improves surveying and mapping efficiency.

[0059] In the prior art, a polygon is drawn by clicking a point with a mouse; the actual land area corresponding to the polygon area is calculated; and an information window is constructed to display the geographical information of the polygon area. However, in the process of use, the shape that actually needs to be measured is generally a complex figure, and multiple marking points need to be clicked in sequence. Moreover, after clicking the wrong marking point, the boundary cannot be adjusted and needs to be redrawn, resulting in complicated operation and low measurement accuracy.

[0060] The applicant has found that during the drawing process, midpoints can be automatically generated, and the outline can be modified by dragging the drawing points and midpoints to refine the drawn outline. The drawn boundary can be easily adjusted, the operation is simple, the outline edge can be refined, and the measurement accuracy can be effectively improved.

[0061] The method and system for quickly acquiring coordinates and areas based on a map application can be applied to mobile terminals such as mobile phones, laptop computers, and tablet computers.

[0062] According to some embodiments of the present application, please refer to Figures 1 to 9 This embodiment relates to a method for quickly obtaining coordinates and areas based on a map application, comprising the following steps:

[0063] Install the plug-in and map application on the terminal respectively, and open the map application and plug-in;

[0064] Search the location whose coordinates and area you need to obtain on the map application and find the location that needs to be measured;

[0065] Click the Start Drawing button to draw the outline. Draw the first point, the second point, and the third point on the map until the outline is closed. Then the drawing ends.

[0066] When drawing the second point, the midpoint between the first and second points is automatically generated. When drawing the third point, the midpoint between the second and third points is automatically generated, and so on.

[0067] After drawing, you can drag the boundary points to modify the outline. The boundary points include the first point, second point, third point to Nth point drawn actively, and the automatically generated midpoint.

[0068] After completing the modification of the outline, click the Save button to complete the drawing of the outline, calculate the actual coordinates and area corresponding to the outline area, and display the actual coordinates and area of ​​the location to be measured.

[0069] In this way, the midpoint can be automatically generated during the drawing process. After the drawing is completed, the drawing point and the automatically generated midpoint can be dragged to refine the drawn outline. The drawn boundary can be easily adjusted. The operation is simple, the outline edge can be refined, and the measurement accuracy can be effectively improved.

[0070] According to some embodiments of the present application, optionally, in the step of dragging a boundary point to modify the contour:

[0071] When you drag an automatically generated midpoint, a midpoint between two points connected to the midpoint is automatically generated.

[0072] In this way, you can achieve infinite subdivision by dragging the automatically generated midpoint, further adjust the contour edge, and continuously nest it to improve the measurement precision.

[0073] According to some embodiments of the present application, optionally, the first point, the second point, the third point to the Nth point actively drawn by the operator on the map are marked with large dots, and the automatically generated midpoint is marked with a small dot;

[0074] In the step where the operator drags the boundary points to modify the contour, when the operator drags the automatically generated midpoint, the midpoint becomes a large dot mark, and the two automatically generated midpoints thereafter are marked with small dots.

[0075] In this way, the identification points can be distinguished. The automatically generated midpoints are marked with small dots. The large dots can be dragged, but no midpoints are generated. After the small dots are dragged, they are automatically converted into large dots, thereby generating two midpoints, which is convenient for adjusting the boundaries of the contour and improves the controllability of the adjustment.

[0076] According to some embodiments of the present application, optionally, in the step of dragging boundary points to modify the outline, the map can be zoomed in, zoomed out, and the interface display position can be moved.

[0077] In this way, the map can be zoomed in, zoomed out, and the interface display position can be moved, making it easy to adjust the boundaries of the outline.

[0078] According to some embodiments of the present application, optionally, after drawing the first point, the second point, and the third point on the map, it is necessary to click the first point again so that its outline will be closed.

[0079] In this way, you can click the first point at any time to complete the closed selection of the contour, making it easier for the operator to select the area range.

[0080] According to some embodiments of the present application, optionally, after completing the step of modifying the profile, the following steps are further included:

[0081] Click the Auto-adjust Boundary button to adjust the boundary of the outline. After the adjustment is completed, click the Save button.

[0082] In this way, you can use the automatic boundary adjustment button to make fine adjustments to the outline boundary, which can effectively improve the accuracy of the edge.

[0083] According to some embodiments of the present application, optionally, adjusting the boundary of the contour specifically includes the following steps:

[0084] The display interface of the terminal at this time is intercepted, and the graphics within the boundary of the contour and the graphics outside the boundary of the contour are analyzed by an image recognition method;

[0085] When the color similarity between the graphics within the boundary of the contour and the graphics outside the boundary of the contour is greater than a preset value, the preset range outside the boundary of the contour is included in the boundary of the contour.

[0086] In this way, by comparing the color similarity between the graphics within the boundary of the outline and the graphics outside the boundary of the outline, the graphics outside the boundary can be included in the outline within a preset range without manual adjustment, thereby improving the adjustment speed.

[0087] According to some embodiments of the present application, optionally, when the color similarity between a graphic within a preset range within the boundary of the contour and a graphic at the center point within the contour is less than a preset value, the graphic within the preset range within the boundary is included outside the boundary of the contour.

[0088] It can recognize map images and automatically adjust the edge range by identifying changes in map color (for example, when reaching the edge of a street, there are green spaces, parks, and ponds next to it, and the map color is obviously different). If it obviously does not conform to the street outline, it can be excluded. If it conforms, it can be included in the outline. This method can be a subtle adjustment of the outline edge or a large area of ​​the outline. It needs to be adjusted in the operator's display interface. The outline that exceeds the display interface cannot be adjusted, which is convenient for the operator to view. If the non-conforming part is found, it can be returned to the original outline boundary, which is more flexible to use.

[0089] In this way, the color similarity between the graphics within the preset range of the boundary and the graphics at the center point of the boundary can exclude the preset range of the boundary without manual adjustment, thereby improving the adjustment speed.

[0090] According to some embodiments of the present application, optionally, an automatic adjustment return button is also included. When the automatic adjustment boundary button is clicked, the boundary of the contour is adjusted. After the adjustment is completed, the automatic adjustment return button can be clicked to return to the original boundary of the contour.

[0091] In this way, the automatic adjustment return button can be used. When the adjustment does not conform to the actual situation, it can return to the original state and perform manual adjustment, which is convenient for the operator.

[0092] This embodiment also relates to a system for quickly acquiring coordinates and areas based on a map application, including any of the methods for quickly acquiring coordinates and areas based on a map application as described above. The system in this case is hardware, specifically a computer device.

[0093] According to some embodiments of the present application, optionally, see Figures 1 to 9 This embodiment relates to a method for quickly obtaining coordinates and areas based on a map application, comprising the following steps:

[0094] Install the plug-in and map application on the terminal respectively, and open the map application and plug-in;

[0095] Search the location whose coordinates and area you need to obtain on the map application and find the location that needs to be measured;

[0096] For example, search for the location of a farm and locate the farm.

[0097] You can only start outlining after clicking "Start Drawing";

[0098] Click the Start Drawing button to draw the outline. Draw the first point, the second point, the third point, and the fourth point on the map. Click the first point again to close the outline.

[0099] When drawing, there is an undo button below;

[0100] When drawing the second point, the midpoint between the first and second points is automatically generated. When drawing the third point, the midpoint between the second and third points is automatically generated. When drawing the fourth point, the midpoint between the third and fourth points is automatically generated. When clicking the first point again, the midpoint between the fourth point and the first point is automatically generated.

[0101] After the contour is closed, you can drag the boundary points to modify the contour. For example, if you move the midpoint between the fourth point and the first point, the midpoint between the first point and the midpoint, and the midpoint between the midpoint and the fourth point will be automatically generated for further refinement.

[0102] For example, if the midpoint between the third point and the fourth point is moved, the midpoint between the third point and the midpoint, and the midpoint between the midpoint and the fourth point are automatically generated for further refinement;

[0103] When dragging boundary points to modify the outline, you can zoom in on the map and move the interface display position to facilitate modifying the outline.

[0104] Different from the prior art, the method for quickly acquiring coordinates and areas based on map applications in this embodiment can automatically generate midpoints during the drawing process. After the drawing is completed, the drawing points and the automatically generated midpoints can be dragged to refine the drawn contour, and the drawn boundaries can be conveniently adjusted. The operation is simple, the contour edges can be refined, and the measurement accuracy can be effectively improved.
