Description

Technical Field

[0001] The present invention relates to the field of digital twins, and particularly to a three-dimensional visualization display system for a park. Background Art

[0002] The supervision of park property in the form of digital twins refers to constructing a three-dimensional virtual mirror image (digital twin) of the physical space of the park (buildings, equipment, infrastructure, etc.), and integrating real-time data collection, spatio-temporal semantic analysis, and intelligent algorithm models to achieve the all-element, all-process, and full-cycle supervision of the operation status of the park. Its essence is to upgrade the traditional property supervision from "post-event handling" to a closed-loop management mode of "real-time warning - historical traceability - intelligent optimization" through "virtual mapping reality and data-driven decision-making".

[0003] Through digital twin technology, the supervision of park property has achieved a leap from "physical world management" to "digital world rehearsal - physical world execution". Its essence is to reconstruct the cognitive, analytical, and decision-making modes of property supervision through the deep integration of data and models.

[0004] However, as a three-dimensional model of the park constructed in the pure visual dimension, if it wants to achieve further digital twins, or rather, to enable users to have other digital twin feelings besides vision, then it is necessary to integrate other data for corresponding modeling. And capture abnormal situations thereby, so as to facilitate better monitoring of the park by users.

[0005] Therefore, there is currently a need for a three-dimensional visualization display system for a park that integrates more data to improve the effect of the three-dimensional model of the park for users' digital twin supervision, enhance the user experience, display abnormal situations as early as possible and make corresponding treatments to reduce losses. Summary of the Invention

[0043] The difference between the three-dimensional visualization display system for a park in the present invention and the prior art lies in that a method for three-dimensional visualization display of a park continuously updates the three-dimensional model of the park through video monitoring within the three-dimensional model of the park; moreover, by screening out the abnormal data of the park, framing the abnormal range of the corresponding abnormal data, and marking the corresponding three-dimensional model of the park, it will be convenient for users to detect the abnormal situation in the park and make timely handling. Since the abnormal situations in the park involve multiple dimensions, we configure different display levels for different situation levels. If the display level is too strong, it will cause disgust among users; if the display level is too weak, it is not convenient for users to view the abnormal situation. Therefore, we configure different display levels for the marked abnormal models according to the movement trajectory of the viewfinder and the size of their abnormal data, and configure different floating layer textures according to different display levels to facilitate the display of the abnormal situation in the three-dimensional model of the park. The present invention integrates the dimensions of abnormal data collection, abnormal data marking, and viewfinder movement capture to adjust the display of abnormal data and abnormal models, improving the user experience of users supervising the abnormal situation in the park in the form of digital twins. By better displaying the abnormal situation, the losses brought by the abnormal situation to users can be reduced.

[0044] The following further describes a three-dimensional visualization display system for a park in the present invention with reference to the accompanying drawings. Description of the Drawings

[0045] Figure 1 It is a flowchart of a three-dimensional visualization display system for a park. Detailed Embodiment

[0046] As Figure 1 shown, a method for three-dimensional visualization display of a park in the present invention includes

[0047] Constructing a three-dimensional model of the park and updating the three-dimensional model of the park by generating a video model based on video monitoring;

[0048] Constructing an abnormal area according to the abnormal data of each coordinate and marking the corresponding three-dimensional model of the park as an abnormal model within the abnormal area;

[0049] Configuring the display level of the abnormal model according to the movement trajectory of the viewfinder and configuring the floating layer texture on the abnormal model according to the display level;

[0050] Outputting the corresponding three-dimensional model of the park within the viewfinder.

[0051] Through video monitoring within the three-dimensional model of the park, the present invention continuously updates the three-dimensional model of the park in real time. Moreover, by screening out the abnormal data in the park, outlining the abnormal range of the corresponding abnormal data, and marking the corresponding three-dimensional model of the park, it is convenient for users to detect the abnormal situation in the park and take timely measures. Since the abnormal situations in the park involve multiple dimensions, we configure different display levels for different situation levels. If the display level is too strong, it will cause disgust among users; if the display level is too weak, it is not convenient for users to view the abnormal situation. Therefore, we configure different display levels for the marked abnormal models according to the movement trajectory of the viewfinder and the size of their abnormal data, and configure different floating layer textures according to different display levels to facilitate the display of the abnormal situation in the three-dimensional model of the park. The present invention integrates the dimensions of abnormal data collection, abnormal data marking, and viewfinder movement capture to adjust the display of abnormal data and abnormal models, enhancing the user experience of supervising the abnormal situation in the park in the form of digital twins. By better displaying the abnormal situation, it reduces the losses brought to users by abnormal situations.

[0052] Through video monitoring within the three-dimensional model of the park, the three-dimensional model of the park is continuously updated dynamically. However, based on visual algorithms, it is impossible to detect more information that humans can perceive but cannot be reflected in the three-dimensional model of the park. The present invention integrates the dimensions of abnormal data collection, abnormal data marking, and viewfinder movement capture to adjust the display of abnormal data and abnormal models, enhancing the user experience of supervising the abnormal situation in the park in the form of digital twins. By better displaying the abnormal situation, it reduces the losses brought to users by abnormal situations.

[0053] In some embodiments, refer to Figure 1 , construct an abnormal area according to the abnormal data of each coordinate, and mark the corresponding three-dimensional model of the park within the abnormal area as an abnormal model, including:

[0054] Collect the noise data and temperature data of each coordinate point in the park, normalize the noise data and temperature data, configure the corresponding weight coefficients, and then calculate the modulus value to generate an abnormal index. Compare the abnormal index of the coordinate point with the abnormal threshold. Consider the noise data and temperature data with an abnormal index greater than the abnormal threshold as abnormal data. Connect the coordinate points with an abnormal index greater than the abnormal threshold, and configure the area covered by the three-dimensional model of the park passed by the connection as the first abnormal area;

[0055] Judge whether the noise data of the coordinate point with an abnormal index greater than the abnormal threshold is greater than the noise threshold. If so, configure a first range circle with the coordinate point as the center and a first distance as the radius, and configure the area covered by the corresponding three-dimensional model of the park within the first range circle as the second abnormal area;

[0056] Determine whether the temperature data of the coordinate points where the abnormal index is greater than the abnormal threshold is greater than the temperature threshold. If so, configure a second range circle with the coordinate point as the center and the second distance as the radius, and configure the area of the corresponding three-dimensional model of the park within the second range circle as the third abnormal area;

[0057] Configure the union of the first abnormal area, the second abnormal area, and the third abnormal area as the abnormal area.

[0058] The present invention first constructs an abnormal index by fusing the above noise data and temperature data in a way of normalization processing and weight configuration, and compares it with the abnormal threshold as an important index for determining whether the coordinate point is abnormal. Then, configure the three-dimensional model of the park along the line (the line that is too long should be deleted according to the subsequent conditions) as the first abnormal area. Due to the different influence ranges of noise and temperature, the abnormal noise is the second abnormal area, and the abnormal temperature is the third abnormal area. In this way, an abnormal area is fused, so that the buildings in the three-dimensional model of the park affected by the abnormal data in this solution can be marked, and thus can be used as an important observation point when property management personnel observe the situation of the park.

[0059] For example:

[0060] The park is a large comprehensive park covering an area of 1 million square meters, including different functional areas such as office buildings, production workshops, storage areas, employee dormitories, dining centers, and green leisure areas. To comprehensively monitor the park environment, a total of 1024 coordinate points are deployed in an irregular distributed manner: Office building: 16 coordinate points are evenly distributed on each floor, with a total of 10 floors, totaling 160;

[0061] Production workshop: According to the equipment distribution and operation area, 256 coordinate points are set;

[0062] Storage area: 128 coordinate points are arranged in key areas;

[0063] Employee dormitory: 32 coordinate points are set in each building, and a total of 256 for 8 buildings;

[0064] Dining center: 32 coordinate points are set in each of the 3 dining centers, totaling 96;

[0065] Green leisure area: 128 coordinate points are scattered.

[0067] Among them, normalization processing

[0068] Temperature normalization: According to the historical temperature data of the park, determine the temperature range as [15°C, 40°C], and the formula is:

[0069] ; Among them, the temperature range can be a set value, and those skilled in the art can collect or directly set it according to the actual situation.

[0070] Noise normalization: Use Z-Score normalization. Given that the mean of the known historical noise data μ = 60 dB and the standard deviation σ = 10 dB, and compress the result to the [0, 1] interval. The formula is:

[0071] ;

[0072] ;

[0073] Among them, Z-Score normalization only translates and scales the data without changing the original distribution form, thereby compressing the data to the [0, 1] interval, which is convenient for horizontal comparison and for matching weights of the same order of magnitude.

[0074] Among them, the weights are shown in the following table: Area Temperature Weight (wT) Noise Weight (wN) Office Building 0.3 0.7 Workshop 0.6 0.4 Storage Area 0.5 0.5 Employee Dormitory 0.4 0.6 Catering Center 0.4 0.6 Greening and Recreation Area 0.5 0.5

[0075] The anomaly threshold is 0.6. That is, only the 5th floor of Building C of P917 Office Building in the table has an anomaly index exceeding the anomaly threshold.

[0076] Among them, determine whether the noise data of the coordinate point where the anomaly index is greater than the anomaly threshold is greater than the noise threshold. If so, configure a first range circle with the coordinate point as the center and the first distance as the radius, and configure the area of the corresponding three-dimensional model of the park within the first range circle as the second anomaly area. It can be understood that: the noise threshold can be 65 dB and the first distance is 30 meters. That is to say, when the noise at the detected coordinate point exceeds 65 dB, the buildings within 30 meters nearby will also be determined to be within the second anomaly area. Even if the center points of two buildings are 40 meters apart, but within a radius of 30 meters from this coordinate point, if a corner of this building can be selected, this building is also configured to be within the second anomaly area.

[0077] Among them, determine whether the temperature data of the coordinate point where the anomaly index is greater than the anomaly threshold is greater than the temperature threshold. If so, configure a second range circle with the coordinate point as the center and the second distance as the radius, and configure the area of the corresponding three-dimensional model of the park within the second range circle as the third anomaly area. It can be understood that: the temperature threshold is 55 degrees and the second distance is 40 meters. That is, the influence range of temperature is relatively larger. It may be caused by situations such as fire and may be accompanied by dangerous gases such as thick smoke. Therefore, the second distance is greater than the first distance. Then, within a radius of 40 meters from the coordinate point where the temperature exceeds the temperature threshold is the third anomaly area.

[0078] In some embodiments, referring to Figure 1 , according to the movement trajectory of the viewfinder, configure the display level of the abnormal model, and configure the floating layer map on the abnormal model according to the display level. It can be understood as:

[0079] Obtain the average speed of the viewfinder within the second unit time, the third quantity of the buildings in the three-dimensional model of the park within the viewfinder, and the third distance between the viewfinder and each building of the three-dimensional model of the park;

[0080] According to the average speed, the third quantity, and the third distance, respectively, at their corresponding display levels, take the lowest display level as the display level of the abnormal model;

[0081] Output the floating layer map on the abnormal model according to the display level of the abnormal model and the abnormal data of the abnormal model.

[0082] Through the above collection of the movement trajectory of the viewfinder, the present invention obtains the average speed within every 5 seconds, and based on this, combines the average number of buildings within 5 seconds and the average distance of all buildings within 5 seconds to output the corresponding display levels for the average speed, the third quantity, and the third distance, and takes the lowest display level as the display level of the abnormal model. Thus, the floating layer map of the abnormal model with different display levels is selected with the most conservative policy to adapt to the situation where the user cannot concentrate on a single abnormal model, and a floating layer map of an abnormal model is generated at a minimalist display level; on the contrary, when the user can observe an abnormal model more concentratedly, a floating layer map of the abnormal model at a more enhanced display level is generated. On the one hand, it saves computing power, increases the number of frames of the image of the three-dimensional model of the park, and enables the user to observe where there is an abnormality; on the other hand, by capturing the user's behavior, when the user focuses on a small number of abnormal models, a more enhanced floating layer map is provided for the abnormal models.

[0083] Among them, according to the average speed, the third quantity, and the third distance, respectively, at their corresponding display levels, take the lowest display level as the display level of the abnormal model. It can be understood as: by querying the display levels corresponding to the average speed, the third quantity, and the third distance in their respective corresponding tables, take the lowest display level as the display level of the abnormal model;

[0084] The table is as follows: Speed Range (m / s) Display Level Trigger Condition Description v<1 Enhanced Level Low-Speed Fine Viewing Mode 1≤v<5 Standard Level Medium-Speed Routine Inspection Mode v≤5 Minimalist Level High-Speed Global Browsing Mode Third Quantity Range Display Level Trigger Condition Description N<5 Enhanced Level Small-Scale Focus 5≤N<20 Standard Level Medium-Scale Viewing N≥20 Minimalist Level Large-Scale Overview Third Distance Range (m) Display Level Trigger Condition Description D<30 Enhanced Level Close-Up 30≤D<100 Standard Level Medium-Distance Routine Viewing D≥100 Minimalist Level Long-Distance Overview

[0085] Among them, the enhanced level is higher than the standard level which is higher than the minimalist level. That is to say, when the enhanced level and the standard level appear simultaneously, the display level of the abnormal model is the standard level.

[0086] Correspondingly,

[0087] A minimalist overlay image can be low-resolution, non-dynamic, silent, and only have warning colors. For example, a small red frame with only the outline of a fire alarm.

[0088] Standard overlays can be medium-pixel, non-dynamic, silent, and have content, such as a complete photo of a fire alarm.

[0089] Enhanced overlays can be high-pixel, dynamic, sound-enabled, and content-rich animations, animated graphics, or 3D models. For example, a dynamic, sound-enabled 3D model of a fire alarm that is constantly performing firefighting actions.

[0090] Among them, the floating layer map on the abnormal model is output according to the display level of the abnormal model and the abnormal data of the abnormal model, including:

[0091] The database pre-stores floating layer maps corresponding to abnormal data, wherein the floating layer maps include floating layer maps of enhanced, standard, and minimalist display levels;

[0092] In response to the display level of the abnormal model and the abnormal data, the corresponding floating layer map is output;

[0093] The center of the floating layer map in the viewfinder is the same as the center of the abnormal model in the viewfinder;

[0094] The area of the floating layer map in the viewfinder is smaller than or equal to the area of the abnormal model in the viewfinder;

[0095] In the viewfinder, the portion of the other park three-dimensional model that blocks the floating layer map and / or the abnormal building is made transparent or semi-transparent.

[0096] This invention overlays a pre-stored database overlay with its corresponding anomaly data and display level over the anomaly model, making it easier for users to view the anomaly model. To ensure that the position and size of the overlay match the user's viewing angle for the 3D campus model, the overlay information is displayed as an overlay for easier viewing. Furthermore, the overlay's position, size, and occlusion should be tailored to facilitate user discovery of the anomaly model.

[0097] In some embodiments, see Figure 1 , output the floating layer map on the abnormal model according to the display level of the abnormal model and the abnormal data of the abnormal model, including:

[0098] Determine whether the abnormal index is greater than the danger threshold. If it is greater than the danger threshold, configure the display level of the abnormal model corresponding to the abnormal index greater than the danger threshold to the highest level; if it is not greater than the danger threshold, determine whether the first area where the second abnormal area coincides with the third abnormal area exceeds the first percentage of the area of the abnormal model. If it exceeds the first percentage, increase the display level of the abnormal model.

[0099] The present invention gets rid of the trouble of the floating layer map that configures the corresponding display level according to the movement track of the viewfinder for the abnormal model with the abnormal index that has reached the danger threshold, and directly assigns it to the highest-level and enhanced display level. Moreover, it can even enlarge the size of its floating layer map or increase the size of the sound corresponding to its floating layer map to increase the display intensity of the floating layer map for displaying the abnormal model, so that no matter how the user adjusts the movement of the viewfinder with any movement track, the user can be reminded of the abnormal situation here in the strongest reminder way. And in the area where abnormal situations are relatively concentrated, we increase the display level of the abnormal model and its floating layer map, so as to facilitate the corresponding attention even when the user fails to notice the corresponding abnormal situation, and facilitate the user to discover relatively serious abnormal situations.

[0100] Among them, increasing the display level of the abnormal model can be understood as adding 1 to a higher level. For example, the enhanced level is increased to the enhanced level, the standard level is increased to the enhanced level, and the minimalist level is increased to the standard level.

[0101] The first percentage can be 50%, that is, if the first area of coincidence exceeds 50% of the area of the top view of this abnormal model, it is regarded as being in the area where problems are concentrated, and its display level should be increased.

[0102] As a variant of the present invention, see Figure 1 , configure the union of the first abnormal area, the second abnormal area, and the third abnormal area as the abnormal area; output the floating layer map on the abnormal model according to the display level of the abnormal model and the abnormal data of the abnormal model, including:

[0103] Define other park 3D models outside the park 3D model corresponding to the coordinate points where the abnormal index in the first abnormal area is greater than the abnormal threshold as the intermediate model;

[0104] Determine whether the intermediate model has an intersection with the second abnormal area and the third abnormal area. If not, determine whether the abnormal index is greater than the danger threshold. If it is greater than the danger threshold, configure the display level of the abnormal model corresponding to the abnormal index greater than the danger threshold to the highest level; if it is not greater than the danger threshold, arrange the intermediate models in descending order according to the minimum distance from the second abnormal area and the third abnormal area, and reduce the display level of the first second percentage of the intermediate models with the largest minimum distance.

[0105] In the present invention, since a part of the abnormal model in the first abnormal area is obtained by covering the connection lines of multiple detection points and there is no real detection data, it is possible that this three-dimensional model of the park is not an abnormal model. Then, in the case of a relatively major danger threshold, the three-dimensional model of the park that is only covered by the connection lines as the intermediate model should also be considered an abnormal model.

[0106] However, in the case where there is no danger, the display level of the intermediate models that are the farthest from the second abnormal area and the third abnormal area among the intermediate models can be reduced, and can even be reduced to a non-abnormal model. The second percentage can be 20%. That is, the display level of the intermediate models that are the largest in the top 20% of the distances from the second abnormal area and the third abnormal area can be reduced.

[0107] Among them, the abnormal threshold is 0.6 and the danger threshold is 0.8. That is, after the abnormal index exceeds 0.8, all intermediate models must be abnormal models in the first abnormal area. That is, when there is no danger, the intermediate models can delete the intermediate models of the first second percentage to allow users to focus more on the determined abnormal models.

[0108] Among them, the way to reduce the display level can be: the enhanced level is reduced to the standard level, the standard level is reduced to the minimalist level, and the minimalist level is reduced to a non-abnormal model.

[0109] As a variation of the present invention, see Figure 1 , configure the union of the first abnormal area, the second abnormal area, and the third abnormal area as the abnormal area; output the floating layer texture map on the abnormal model according to the display level of the abnormal model and the abnormal data of the abnormal model, which can be understood as:

[0110] Define the other three-dimensional models of the park other than the three-dimensional models of the park corresponding to the coordinate points with an abnormal index greater than the abnormal threshold in the first abnormal area as intermediate models;

[0111] Judge whether the intermediate model has an intersection with the second abnormal area and the third abnormal area. If not, judge whether the abnormal index is greater than the danger threshold. If it is greater than the danger threshold, configure the display level of the abnormal model corresponding to the abnormal index greater than the danger threshold as the highest level; if it is not greater than the danger threshold, arrange the intermediate models in descending order according to the minimum distance from the second abnormal area and the third abnormal area, and delete the intermediate models of the first second percentage with the largest minimum distance from the first abnormal area.

[0112] In the present invention, since a part of the abnormal model in the first abnormal area is obtained by covering the connection lines of multiple detection points and there is no real detection data, it is possible that this three-dimensional model of the park is not an abnormal model. Then, in the case of a relatively major danger threshold, the three-dimensional model of the park only covered by the connection lines as the intermediate model should also be considered an abnormal model.

[0113] However, in the case where there is no danger, the intermediate models in the top second percentage that are farthest from the second abnormal area and the third abnormal area among the intermediate models can be defined as non-abnormal models. The second percentage can be 20%. That is, the top 20% of the intermediate models with the largest distances from the second abnormal area and the third abnormal area can have their display levels reduced.

[0114] As Figure 1 shown, a three-dimensional visualization display system for a park includes

[0115] a modeling module for constructing a three-dimensional model of the park and updating the three-dimensional model of the park based on a video surveillance to generate a video model;

[0116] a processor for constructing an abnormal area according to the abnormal data of each coordinate, marking the corresponding three-dimensional model of the park as an abnormal model within the abnormal area; configuring the display level of the abnormal model according to the movement trajectory of the viewfinder, and configuring a floating layer texture map on the abnormal model according to the display level; and outputting the corresponding three-dimensional model of the park within the viewfinder.

[0117] In the present invention, the three-dimensional model of the park is continuously updated in real time through video surveillance within the three-dimensional model of the park; and then, the abnormal data of the park is screened out, the abnormal range of the corresponding abnormal data is framed, and the corresponding three-dimensional model of the park is marked, which will facilitate users to detect the abnormal situation of the park and make timely handling. Since the abnormal situation of the park involves multiple dimensions, we configure different display levels for different situation levels. If the display level is too strong, it will cause disgust among users. If the display level is too weak, it is not convenient for users to view the abnormal situation. Therefore, we configure different display levels for the marked abnormal models according to the movement trajectory of the viewfinder and the magnitude of their abnormal data, and configure different floating layer texture maps according to different display levels to facilitate the display of the abnormal situation in the three-dimensional model of the park. The present invention integrates the dimensions of abnormal data collection, abnormal data marking, and movement capture of the viewfinder to adjust the display of abnormal data and abnormal models, improving the user experience of users supervising the abnormal situation of the park in the form of digital twins, and reducing the losses brought to users by abnormal situations by better displaying the abnormal situation.

[0118] As a variation of the present invention, refer to Figure 1, construct an abnormal area based on the abnormal data of each coordinate, and mark the corresponding 3D model of the park as an abnormal model within the abnormal area, including:

[0119] Collect the noise data and temperature data of each coordinate point in the park, normalize the noise data and temperature data, configure corresponding weight coefficients, and then calculate the modulus value to generate an abnormal index. Compare the abnormal index of the coordinate point with the abnormal threshold. Consider the noise data and temperature data with an abnormal index greater than the abnormal threshold as abnormal data. Connect the coordinate points with an abnormal index greater than the abnormal threshold, and configure the area covered by the 3D model of the park passed by the connection as the first abnormal area;

[0120] Judge whether the noise data of the coordinate point with an abnormal index greater than the abnormal threshold is greater than the noise threshold. If so, configure a first range circle with the coordinate point as the center and the first distance as the radius, and configure the area covered by the corresponding 3D model of the park within the first range circle as the second abnormal area;

[0121] Judge whether the temperature data of the coordinate point with an abnormal index greater than the abnormal threshold is greater than the temperature threshold. If so, configure a second range circle with the coordinate point as the center and the second distance as the radius, and configure the area covered by the corresponding 3D model of the park within the second range circle as the third abnormal area;

[0122] Configure the union of the first abnormal area, the second abnormal area, and the third abnormal area as the abnormal area.

[0123] The present invention first constructs an abnormal index by fusing the above noise data and temperature data in a way of normalization processing and weight configuration, and uses this to compare with the abnormal threshold as an important indicator for determining whether the coordinate point is abnormal. Then, configure the 3D model of the park passed by its connection (the connection that is too long should be deleted according to the following conditions) as the first abnormal area. Due to the different influence ranges of noise and temperature, the abnormal noise is the second abnormal area, and the abnormal temperature is the third abnormal area. In this way, an abnormal area is fused, so that the buildings in the 3D model of the park affected by the abnormal data in this solution can be marked, and thus can be used as an important observation point when property personnel observe the park situation.

[0124] As a variant of the present invention, see Figure 1 , configure the union of the first abnormal area, the second abnormal area, and the third abnormal area as the abnormal area; output the floating layer texture map on the abnormal model according to the display level of the abnormal model and the abnormal data of the abnormal model, including:

[0125] Define the other 3D models of the park other than the 3D model of the park corresponding to the coordinate points with an abnormal index greater than the abnormal threshold in the first abnormal area as intermediate models;

[0126] Determine whether the intermediate model has an intersection with the second abnormal area and the third abnormal area. If not, determine whether the abnormal index is greater than the danger threshold. If it is greater than the danger threshold, configure the display level of the abnormal model corresponding to the abnormal index greater than the danger threshold to the highest level; if it is not greater than the danger threshold, arrange the intermediate models from large to small according to the minimum distance from the second abnormal area and the third abnormal area, and reduce the display level of the intermediate models in the first second percentage with the largest minimum distance.

[0127] In this invention, since a portion of the anomaly model for the first anomaly area is derived by overlaying lines connecting multiple detection points, for which no real detection data exists, this 3D park model may not be an anomaly model. Therefore, in the event of a significant danger threshold, the 3D park model, which serves as an intermediate model and is only covered by lines, should also be considered an anomaly model.

[0128] However, if no danger occurs, the display level of the intermediate models in the first second percentage, which are farthest from the second and third abnormal areas, can be lowered, or even lowered to normal models. The second percentage can be 20%. That is, the display level of the intermediate models in the first 20% of the distance from the second and third abnormal areas can be lowered.

[0129] As a variation of the present invention, see Figure 1 , configuring the union of the first abnormal area, the second abnormal area, and the third abnormal area as an abnormal area; outputting a floating layer map on the abnormal model according to the display level of the abnormal model and the abnormal data of the abnormal model, which can be understood as:

[0130] The other three-dimensional models of the park, other than the three-dimensional model of the park corresponding to the coordinate point having an anomaly index greater than the anomaly threshold in the first anomaly area, are defined as intermediate models;

[0131] Determine whether the intermediate model has an intersection with the second abnormal area and the third abnormal area. If not, determine whether the abnormal index is greater than the danger threshold. If it is greater than the danger threshold, configure the display level of the abnormal model corresponding to the abnormal index greater than the danger threshold to the highest level; if it is not greater than the danger threshold, arrange the intermediate models from large to small according to the minimum distance from the second abnormal area and the third abnormal area, and delete the intermediate models in the first second percentage with the largest minimum distance from the first abnormal area.

[0132] In the present invention, since a part of the abnormal model in the first abnormal area is obtained by covering the connection lines of multiple detection points and there is no real detection data, it is possible that this three-dimensional model of the park is not an abnormal model. Then, in the case of a relatively significant danger threshold, the three-dimensional model of the park that is only covered by the connection lines and serves as the intermediate model should also be regarded as an abnormal model.

[0133] However, in the case where there is no danger, the intermediate models in the first second percentage that are the farthest from the second abnormal area and the third abnormal area among the intermediate models can be defined as non-abnormal models. The second percentage can be 20%. That is, the intermediate models in the largest first 20% that are the farthest from the second abnormal area and the third abnormal area can have their display levels reduced.

Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
