Description

Technical Field

[0001] This invention belongs to the field of personnel location configuration technology in digital models, specifically involving a personnel location allocation method based on the "winding stream and floating wine cups" cultural and entertainment scenario. Background Technology

[0002] With the advancement of 3D digitization of the winding stream garden landscape, creating digital static 3D models has become easier. However, for the simulation and restoration of folk activities, such as whether the allocation of personnel positions in the winding stream entertainment scene is reasonable, existing technologies rarely provide scientific and rational analysis of the optimal number and location of personnel. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a method for personnel location allocation in a winding stream entertainment scene, so as to solve at least one of the above-mentioned problems in the prior art.

[0004] To achieve the above objectives, one or more embodiments of this application provide a method for personnel location allocation in a winding stream entertainment scenario, which includes the following steps:

[0005] S1: Based on the distribution of water areas in the actual winding water scene, extract or draw a plan view of the actual winding water scene from the map, extract the center line of the water area in the plan view, use the center line as the route of the wine cup flow, and simulate the wine cup as a node in the center line;

[0006] S2: Combining the water flow direction and parameter information of each segment or node of the centerline within the water area, analyze and determine the segment intervals in the centerline where mooring is likely to occur, and designate these segment intervals as risk segments;

[0007] S3: Extract the risk segment information of the ship's berthing, combine it with the ship berthing risk indicators to determine and read the number and location of the existing risk segments, and configure the location and number of personnel according to the determined risk segment information.

[0008] Based on the above technical solution of the present invention, the following improvements can also be made:

[0009] Optionally, step S1 includes:

[0010] S101: Correct the plan view of the actual meandering water scene extracted or drawn from the map, and draw the vector surface of the water area;

[0011] S102: Convert the vector surface of the water area into raster data for reclassification; classify as having water area, represented by 1; and having no water area, represented by 0;

[0012] S103: Use a binary image to vectorize the raster lines of the raster data. Set the maximum width value for vectorization capture according to the width of the actual meandering scene, and then extract the center line based on the Steger algorithm.

[0013] Optionally, step S2 includes:

[0014] S201: Divide the extracted centerline into appropriate equal segments, define the azimuth of each segment north of it as 0 degrees, determine the inclination angle of each segment, and obtain the difference in inclination angle between adjacent segments.

[0015] S202: Extract the turning arc segment with the maximum tilt angle. This turning arc segment is composed of line segments whose maximum tilt angle difference between adjacent line segments in the risk segment is greater than a set threshold.

[0016] Optionally, the extracted turning arc segments with the maximum tilt angle are marked, and it is determined whether the marked line segments have adjacent line segments. If so, the marked line segments are merged with the adjacent line segments to obtain each maximum turning arc segment.

[0017] Optionally, step S3 includes:

[0018] S301: Calculate the turning radius, and determine the turning radius based on the arc length and central angle corresponding to each turning arc segment;

[0019] S302: Mark turning segments with a turning angle greater than 30° and less than 60°, and turning radii less than 5 times the length of the bend or greater than 10 times the length of the bend, as risk segments; otherwise, do not mark or mark as risk-free segments. Also mark turning segments with a turning angle greater than 60° and a turning radius less than or equal to 10 times the length of the bend as risk segments; otherwise, do not mark or mark as risk-free segments.

[0020] S303: Summarize and identify the line segments with potential mooring risks, and accordingly allocate the number of personnel and approximate seating positions within the identified line segments.

[0021] The beneficial effect of this invention is that it provides a method for personnel allocation in the "Floating Wine Cups on a Winding Stream" entertainment scene. The winding stream is simulated as a naturally flowing body of water, and the wine cups are considered as boats. Starting from the risk range of collisions and mooring of boats flowing in a natural waterway, relevant indicators are determined in reverse to identify areas in the "Floating Wine Cups on a Winding Stream" scene where mooring risks are most likely to occur. This allows for the deduction of the maximum number of moorings and their corresponding locations. This scientifically solves the problem of personnel allocation in the "Floating Wine Cups on a Winding Stream" entertainment activity, facilitating the determination of the optimal number and location of personnel.

[0036] S2: Combining the water flow direction and parameter information of each segment or node of the centerline within the water area, analyze and determine the segment intervals in the centerline where mooring is likely to occur, and designate these segment intervals as risk segments;

[0037] Step S2 includes:

[0038] S201: Divide the extracted centerline into appropriate equal segments, define the azimuth of each segment north of it as 0 degrees, determine the inclination angle of each segment, and obtain the difference in inclination angle between adjacent segments.

[0045] Understandably, this embodiment provides a method for personnel allocation in a winding stream entertainment scenario. To analyze the possibility of floating cups colliding and coming to a stop, the winding stream is simulated as a naturally flowing body of water, and the cups are considered as boats. Starting from the risk range of collisions and mooring of boats flowing in a natural waterway, relevant indicators are determined in reverse to identify areas in the winding stream entertainment scenario where mooring risks are likely to occur. This allows for the deduction of the maximum number of moorings and their corresponding locations. This scientifically solves the personnel allocation problem in the winding stream entertainment activity, facilitating the determination of the optimal number and location of personnel.

[0046] Specifically, such as Figure 1 As shown, Figure 1 This is a flowchart of this embodiment. In this embodiment, the surface features of the meandering river are obtained based on surveying or directly extracted from the map. The surface features are then converted into raster data and reclassified. Then, the ArcScan tool is used to vectorize the data and extract the centerline. The data is then segmented and processed. The azimuth and inclination angles are calculated to obtain the azimuth and inclination angle difference. The turning arc segment with the maximum inclination angle is extracted, and the berthing risk segment is extracted for personnel allocation.

[0047] Based on the ship berthing risk index, the turning radius R and the length L of the vessel are combined to mark turning segments with a turning angle greater than 30° and less than 60°, and turning segments with a turning radius less than 5 times the length of the vessel or greater than 10 times the length of the vessel as risk segments; turning segments with a turning angle greater than 60° and a turning radius less than 10 times the length of the vessel are also marked as risk segments, otherwise they are not marked or are marked as risk-free segments; the risk segments of vessel berthing are accurately determined, so as to achieve precise and maximized allocation of personnel.

[0048] Specifically, as shown in Table 1, there are several risk factors affecting the berthing of the "Shang". When the turning angle θ of the "Shang" is greater than 30° and less than 60°, we calculate the radius R of this turning segment. If the radius R is less than 5L or greater than 10L (L is the length of the "Shang"), there is a risk of berthing in this segment. When the turning angle θ of the "Shang" is greater than 60°, if the radius R of this turning segment is less than or equal to 10L (L is the length of the "Shang"), there is also a risk of berthing in this segment.

[0049] Table 1. Mooring Risk Factors

[0050]

[0051] Figure 2 The diagram shows a swirling water survey map in one scenario. After the plan is drawn, it can be corrected based on the map or on actual on-site measurements. Figure 3 An example is provided illustrating the corrected vector diagram of the meandering waterway environment within the displayed terrain. Among other things, Figure 3 The rectangle in the image represents the original personnel assignment positions.

[0052] Extracting berthing risk zones ultimately determines the maximum number of personnel to be allocated and their specific locations. This includes:

[0053] Calculate the turning radius. Using the mathematical formula: radius corresponding to arc length = 180° * arc length / central angle * π, the radius corresponding to the arc length is the turning radius R.

[0054] For turning angles greater than 30° and less than 60°, if the turning radius R is less than 5L or greater than 10L (L is the length of the saddle), there is a risk of stopping and it should be marked; otherwise, it should be excluded. When the turning angle is greater than 60°, if the turning radius R is less than or equal to 10L (L is the length of the saddle), there is also a risk of stopping and it should be marked; otherwise, it should be excluded.

[0055] Finally, the line segment intervals with parking risks were summarized, such as... Figure 6 As shown.

[0056] Then, the location and number of areas corresponding to the concave bank in that section are located along the direction of the water. Taking the meandering river as an example, the maximum number of personnel allocation positions is 9, as shown in position 1-9 in the diagram. These positions are all close to the concave bank of the water. It can be seen that... Figure 2 The discrepancies in the original planned locations indicate an unreasonable allocation within the original plan. Figure 2 The flowing cup pool in the example can be understood as the meandering water area in the embodiment, with stone benches for people to sit on.
