[0046] It should be noted that the specific manner of obtaining the starting control point, the intermediate control point and the terminating control point is not limited in the present application and can be set according to actual conditions.

[0047] It should be noted that the specific implementation manner of the plotting algorithm based on the control point is not limited in the present application and can be set according to actual conditions.

[0048]

[0049] ​As a possible implementation manner, the control point set can be generated by clicking the map through the map interaction or the like, so as to obtain the position of the control point, wherein the clicked map is the map before the dynamic plotting.

[0050] For example, the following control point set can be obtained by clicking the map:

[0051] (c s ,c k ,……c e ), c = (x, y)

[0052] wherein c s is the starting control point, c k … is the intermediate control point, and c e is the terminal control point.

[0053] Further, after obtaining the starting control point, the intermediate control point and the terminal control point, the plotting reference curve can be obtained according to the starting control point, the intermediate control point and the terminal control point, and then the initial plotting graph can be plotted according to the plotting reference curve.

[0054] S102, simulating the starting control point and dynamically calculating the intermediate control point according to the initial plotting graph, to obtain the simulated starting control point and the dynamically calculated intermediate control point.

[0055] It should be noted that, since the terminal control point usually refers to the fixed information such as the incident location and the accident center, the present application only needs to simulate the starting control point and dynamically calculate the intermediate control point during the dynamic plotting.

[0056] It should be noted that the specific manner of simulating the starting control point and dynamically calculating the intermediate control point according to the initial plotting graph to obtain the simulated starting control point and the dynamically calculated intermediate control point in the present application is not limited, and can be set according to the actual situation.

[0057] As a possible implementation manner, for the simulated starting control point, the simulated starting control point can be obtained by sampling the simulated control point and driving the simulation process; for the dynamically calculated intermediate control point, the dynamically calculated intermediate control point can be obtained by tolerance processing.

[0058] S103, plotting the target plotting graph according to the terminal control point, the simulated starting control point and the dynamically calculated intermediate control point.

[0059] In the present application, after obtaining the terminal control point, the simulated starting control point and the dynamically calculated intermediate control point, the target plotting graph can be obtained by replotting in various ways.

[0060] As a possible implementation, the initial plotting figure can be redrawn according to the starting control point, the intermediate control point and the ending control point to obtain the target plotting figure.

[0061] The application provides a plotting method based on dynamic deduction. The starting control point, the intermediate control point and the ending control point are obtained, and an initial plotting figure is plotted according to the starting control point, the intermediate control point and the ending control point. Then, the starting control point is simulated and the intermediate control point is dynamically calculated to obtain a simulated starting control point and a dynamically calculated intermediate control point. Finally, a target plotting figure is plotted according to the ending control point, the simulated starting control point and the dynamically calculated intermediate control point. Thus, the application provides a dynamic plotting method based on dynamic deduction, which can solve the problem that manual plotting cannot meet the demand of dynamic deduction of rescue forces in the process of simulation and rescue, and cannot dynamically display the rescue progress with the passage of time in the subsequent rescue review. The application can accurately, reliably and efficiently perform dynamic plotting and provide support for the trend change of dynamic simulation of rescue forces in scenarios such as scenario deduction, simulation, and emergency command.

[0062] It should be noted that, when the initial plotting figure is plotted according to the starting control point, the intermediate control point and the ending control point, a plotting reference curve can be obtained, and then the initial plotting figure is plotted based on the plotting reference curve.

[0066] S301. Obtain a Bezier curve point set according to the starting control point, the intermediate control point and the ending control point.

[0067] As a possible implementation, after the starting control point, the intermediate control point and the ending control point are obtained, the following Bezier curve function can be used for processing to generate a Bezier curve point set P b :

[0068] Pb =bezier(c s ,c k ,……c e ,count)

[0069] Where count is the number of output points, and bezier is the Bézier curve algorithm.

[0070] S302. Fit the set of points of the Bézier curve to obtain the plotting reference curve.

[0071] As one possible implementation, in obtaining the set of Bézier curve points P b Then, the following fitting function can be used to obtain the plotting reference curve L. b :

[0072] L b =fit(P b )

[0073] S202. Draw the initial plotting figure based on the starting control point, intermediate control point, ending control point and plotting reference curve.

[0074] As one possible implementation, after obtaining the starting control point, intermediate control points, ending control point, and plotting reference curve, the following plotting algorithm function can be used to generate the initial plotting graph G0:

[0075] G0 = Plotting(L b ,c s ,c k ,……c e )

[0076] Therefore, the dynamic inference-based plotting method proposed in this application can obtain plotting reference curves based on the starting control points, intermediate control points, and ending control points, and then draw initial plotting figures based on the starting control points, intermediate control points, ending control points, and plotting reference curves, eliminating the need for manual drawing and further ensuring plotting efficiency. This lays the foundation for accurate, reliable, and efficient dynamic plotting.

[0077] It should be noted that in this application, when simulating the starting control point and dynamically calculating the intermediate control point based on the initial plotting, a dynamic simulation method is used to obtain the simulated starting control point and the dynamically calculated intermediate control point.

[0080] As one possible implementation, the target smoothness factor can be obtained and determined based on the Bézier curve point set P. b The simulated sampling point P is calculated using the following curve interpolation function, along with the target smoothness factor soothness. s :

[0081] P s =curvilinear(P b (soothness)

[0082] Where, curvilinear is the curve interpolation function.

[0083] S402. Obtain the number of simulated sampling points moved between adjacent sampling time points, and obtain the simulation start control point based on the simulated sampling points and the number of simulated sampling points moved.

[0084] As one possible implementation, such as Figure 5 As shown, based on the above embodiment, the specific process of obtaining the number of simulated sampling points moved between adjacent sampling time points in the above steps includes the following steps:

[0085] S501, Obtain the simulation start time and simulation end time.

[0086] It should be noted that the timing unit during the simulation can be set according to the actual situation; for example, the timing unit can be set to seconds.

[0087] S502. Based on the simulation start time, simulation end time, and simulation sampling point, obtain the number of simulation sampling points moved.

[0088] As one possible implementation, after obtaining the simulation start time and simulation end time, the number of sampling points moved, c, between adjacent time points can be calculated using the following equal division method:

[0089]

[0090] Where, count(P) s ) represents the number of simulated sampling points, t e t0 is the simulation end time, and t0 is the simulation start time.

[0091] Further, the simulation time t i Point information calculation simulation starting control point s i :

[0092] s i = P s [c x i]

[0093] Wherein, c x i is the index number of the simulation sampling point P s The point set, and [] is the value of the index position.

[0094] S403, get the index position of the intermediate control point in the simulation sampling point, and get the dynamically calculated intermediate control point according to the simulation sampling point and the index position.

[0095] In the embodiment of the application, the intermediate control point C k In the simulation sampling point P s The index position of the intermediate control point in the simulation sampling point can be calculated according to the initial plotting graph G0

[0096]

[0097] Further, after obtaining the index position of the intermediate control point in the simulation sampling point , the dynamically calculated intermediate control point can be obtained according to the simulation sampling point and the index position.

[0098] As a possible implementation manner, as shown in Figure 6 On the basis of the above embodiment, the specific process of obtaining the dynamically calculated intermediate control point according to the simulation sampling point and the index position in the above step includes the following steps:

[0099] S601, according to the simulation sampling point and the index position, the proportion factor of the position of the intermediate control point in the initial plotting graph is obtained.

[0100] As a possible implementation manner, the proportion factor of the position of the intermediate control point C S In the plotting shape can be calculated according to the index position k The number of points of the simulation sampling point P

[0101]

[0102] S602, according to the simulation sampling point and the proportion factor, the dynamically calculated intermediate control point is obtained.

[0103] ​As a possible implementation, the index number of the intermediate control point in the simulation sampling point can be calculated by using the proportional method, so as to obtain the new intermediate control point, i.e. the dynamically calculated intermediate control point c' k :

[0104]

[0105] Further, after obtaining the simulation intermediate point, a new intermediate control point set, i.e. the dynamically calculated intermediate control point set, can be generated.

[0106] Therefore, the plotting method based on dynamic deduction proposed in the present application can obtain the simulation starting control point through processes such as sampling simulation control points and driving simulation processes, and obtain the dynamically calculated intermediate control point through processes such as tolerance processing, thereby intelligently realizing accurate, reliable and efficient dynamic plotting.

[0107] Further, in the present application, after obtaining the simulation starting control point and the dynamically calculated intermediate control point, the target plotting graph G e may be plotted according to the termination control point c i , the simulation starting control point s k and the dynamically calculated intermediate control point c′ i .

[0108] As a possible implementation, the following formula can be used for obtaining:

[0109] P’ b =bezier(s i ,c′ k ,……c e ,count)

[0110] L’ b =fit(P’ b )

[0111] G i =Ploting(L’ b, s i ,c′ k ,……c e )

[0112] Further, in the present application, after plotting the target plotting graph, the current map can also be updated according to the target plotting graph.

[0113] As a possible implementation, as shown in FIG. 6, on the basis of the above embodiment, the method specifically comprises the following steps: Figure 7

[0114] S701, geometrically converting the target plotting graph to obtain the geometric shape of the converted target plotting.​

[0115] In the embodiment of the application, after the target plotting graph is drawn, the geometric data structure of the plotting graph can be analyzed to convert it into a plurality of simple geometric objects of the adaptive map platform, i.e., the geometric shape of the converted target plotting.

[0116] S702, geometric object style information is acquired, and the target plotting graph is drawn to the current map according to the geometric object style information and the geometric shape of the converted target plotting.

[0117] In the embodiment of the application, after the converted target plotting graph is obtained, the geometric shape of the converted target plotting and the geometric object style information can be used to output to the map in real time through the rendering mechanism of the map platform to obtain the current map.

[0118] The geometric object style information refers to attribute information of points, lines and surfaces, such as color, thickness and the like.

[0119] The current map is different from the map before dynamic plotting is performed when the starting control point, the intermediate control point and the terminal control point are acquired, and is the map obtained after dynamic plotting is performed.

[0120] In summary, the plotting symbol dynamic calculation and device are based on the plotting algorithm based on the control point, simulate the position of the starting control point according to the initial plotting graph geometric information, calculate the position of the intermediate control point in a trend prediction manner according to the plotting curve information and the plotting geometric information, and re-construct the plotting shape to simulate the change of the rescue force advancing graph with the position change and deduce the rescue process.

[0121] For example, as shown in FIG. 1, a processing system composed of a plurality of modules is taken as an example for explanation and description. Figure 8

[0122] The system of the application includes a plotting initialization module, a starting control point simulation module, a plotting dynamic calculation module and a plotting drawing module, which respectively complete the functions of initializing the plotting shape, simulating the control point, dynamic calculation and plotting drawing to realize the dynamic simulation process of the plotting symbol.

[0123] Therefore, the plotting method based on dynamic deduction proposed in the application can generate a starting control point set in a specified time period according to an initial plotting graph by using a curve interpolation algorithm, dynamically calculate an intermediate control point by using a curve prediction algorithm through the position of the starting control point, a plotting reference curve and a plotting shape, and realize the dynamic change of the plotting shape based on the calculation method of dynamically changing the plotting shape of the map symbol graph with the time change, and realize the dynamic simulation process of the advancing direction of the emergency rescue force in the dynamic deduction scene through the function logic of the plotting symbol dynamic calculation device.​
