[0075] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0076] It is understandable that in the prior art, the three-dimensional simulation management process of the intelligent warehouse is generally limited to simulation management according to preset and solidified three-dimensional models, which has some significant defects: First, for overly simple three-dimensional models, it is impossible to perform detailed and realistic three-dimensional simulation of the dynamic process of objects in the intelligent warehouse, which in turn affects remote observation and management; Second, for overly complex three-dimensional models, when computer resources are limited, it is easy to cause freezes, delays, or even crashes during the simulation process, affecting the effect of the three-dimensional simulation.

[0077] To solve the above problems, an embodiment of the present invention discloses a three-dimensional simulation management method and system for an intelligent stereoscopic warehouse, which obtains warehouse storage data of a target stereoscopic warehouse, determines multiple types of storage items, matches multiple corresponding basic item models, and performs model simplification processing to generate multiple simplified item models; initializes and displays a preset warehouse basic model, receives management interaction operations of the target management personnel on the warehouse basic model, and determines a monitoring management area; obtains storage dynamic information of the target stereoscopic warehouse, performs simulation monitoring planning on the storage dynamic information in the monitoring management area, generates a monitoring view window, and determines storage dynamic items; selects a target basic model and a target simplified model corresponding to the storage dynamic items from multiple basic item models and multiple simplified item models; generates a simulation management screen of the monitoring view window in real time, performs screen ratio analysis and comparison on the simulation management screen, and selects a target basic model or a target simplified model for simulation display. It can match multiple basic models of objects, generate multiple simplified models of objects, analyze and compare the screen ratio of the simulation management screen in the monitoring perspective window, and select the target basic model or target simplified model for simulation display according to different situations. It can avoid the problems of lack of detail and realism, as well as freezes, delays and crashes, thereby achieving high-quality and smooth 3D simulation and providing accurate and efficient management assistance.

[0078] Specifically, Figure 1 The flowchart of the three-dimensional simulation management method of the intelligent stereoscopic warehouse provided by the embodiment of the present invention is shown.

[0079] In a preferred embodiment of the present invention, a three-dimensional simulation management method for an intelligent stereoscopic warehouse comprises the following steps:

[0080] Step S101: obtain warehouse storage data of the target stereoscopic warehouse, determine multiple storage item types, match multiple corresponding item basic models, and perform model simplification processing to generate multiple item simplified models.

[0081] In an embodiment of the present invention, a target stereoscopic warehouse that needs to be managed by three-dimensional simulation is determined, warehouse storage data of the target stereoscopic warehouse is obtained, and then the types of storage items in the warehouse storage data are identified to determine multiple types of storage items in the target stereoscopic warehouse, and then multiple basic models of items corresponding to the storage item types are obtained by matching from a preset basic model database, and multiple basic models of items are meshed on the surface of each basic model of the item so that the outer surface of each basic model of the item is constructed and represented by multiple triangular meshes, and multiple corresponding meshed basic models are generated, and then in each meshed basic model, the vertices of the triangular mesh are selected to determine the corresponding triangle mesh in each meshed basic model. Multiple basic vertices are selected, and correlation analysis is performed on the multiple basic vertices, the correlation frequency ratios corresponding to the multiple basic vertices are calculated, and the lengths of the edges formed by adjacent basic vertices are measured, and the maximum length is selected from them. By calculating the edge weight value corresponding to each edge, the multiple edge weight values ​​are compared with the preset weight threshold, and the two basic vertices corresponding to the edge weight value greater than the weight threshold are marked as optimized vertices, so that multiple optimized vertices can be selected from each meshed basic model, and then the basic vertices other than the optimized vertices are deleted in the multiple meshed basic models, and the model is simplified with the retained multiple optimized vertices to generate multiple simplified object models. Specifically, the edge weight value calculation formula is:

[0082] ;

[0083] ;

[0084] in, Representative The base vertices, Representative The base vertices, represent and The edges that form for The correlation frequency ratio of for The correlation frequency ratio of for The length of the corresponding side, is the maximum edge length in the corresponding meshed base model, and is the preset adjustment factor.

[0085] It can be understood that the basic model of the item is a three-dimensional model that can display all the appearance details of the corresponding type of storage item; the simplified model of the item is a three-dimensional model that can display some of the appearance details of the corresponding type of storage item.

[0086] It can be understood that since the meshed basic model is composed of multiple triangular meshes, and each triangular mesh has three basic vertices, there are direct, indirect and irrelevant connection relationships between the basic vertices on the multiple triangular meshes of the meshed basic model, among which a direct connection is a relationship in which two adjacent basic vertices are directly connected through an edge; an indirect connection is a relationship in which two non-adjacent basic vertices are connected to another basic vertex in the middle through two edges; and an irrelevant connection is a relationship other than a direct connection and an indirect connection.

[0087] It can be understood that the association frequency ratio of a basic vertex is the ratio of the number of vertices directly connected to the basic vertex to the number of vertices indirectly connected to the basic vertex.

[0088] Understandably, and These two preset adjustment coefficients can be adjusted accordingly according to different model simplification requirements. Specifically, When the value is larger, it can better avoid isolated faces of the model, thus improving the geometric closure of the model. The larger the value, the better it can maintain the shape of the model.

[0089] Specifically, Figure 2 A flow chart of model simplification processing in the method provided by an embodiment of the present invention is shown.

[0090] Among them, in the preferred embodiment provided by the present invention, the acquisition of warehouse storage data of the target stereoscopic warehouse, determining multiple types of storage items, matching multiple corresponding basic item models, and performing model simplification processing to generate multiple simplified item models specifically includes the following steps:

[0091] Step S1011, obtaining warehouse storage data of the target three-dimensional warehouse;

[0092] Step S1012: performing type identification on the warehouse storage data to determine multiple storage item types;

[0093] Step S1013: Match and obtain multiple basic item models corresponding to the types of stored items from a preset basic model database;

[0094] Step S1014, performing surface meshing processing on the plurality of object basic models to generate a plurality of corresponding meshed basic models;

[0095] Step S1015: selecting and analyzing basic vertices in the plurality of meshed basic models respectively, and calculating corresponding edge weight values;

[0096] Step S1016: compare the plurality of edge weight values ​​with a preset weight threshold, and select a plurality of optimized vertices in each of the plurality of meshed basic models;

[0097] Step S1017: In the plurality of meshed basic models, based on a plurality of corresponding optimized vertices, model simplification processing is performed to generate a plurality of simplified object models.

[0098] Furthermore, the three-dimensional simulation management method of the intelligent stereoscopic warehouse also includes the following steps:

[0099] Step S102: Initialize and display a preset warehouse basic model, receive management interaction operations of the target manager on the warehouse basic model, and determine a monitoring management area.

[0100] In an embodiment of the present invention, an initialization display interface is created, in which a preset warehouse basic model is initialized and displayed, and in the initialization display interface, management interaction operations (including dragging, rotating, zooming, sliding, etc.) of the warehouse basic model by the target manager are received, and then the management interaction operations are responded to to determine the monitoring management area.

[0101] Specifically, Figure 3 A flow chart of determining a monitoring management area in a method provided in an embodiment of the present invention is shown.

[0102] Among them, in the preferred embodiment provided by the present invention, the initialization of displaying a preset warehouse basic model, receiving the management interaction operation of the target manager on the warehouse basic model, and determining the monitoring management area specifically include the following steps:

[0103] Step S1021, creating an initialization display interface;

[0104] Step S1022: Initialize and display the preset warehouse basic model in the initialization display interface;

[0105] Step S1023: receiving management interaction operations of the target manager on the warehouse basic model in the initialization display interface;

[0106] Step S1024: respond to the management interaction operation and determine a monitoring management area.

[0107] Furthermore, the three-dimensional simulation management method of the intelligent stereoscopic warehouse also includes the following steps:

[0108] Step S103, obtaining storage dynamic information of the target stereoscopic warehouse, performing simulation monitoring planning on the storage dynamic information in the monitoring management area, generating a monitoring view window, and determining storage dynamic items.

[0109] In an embodiment of the present invention, by acquiring storage dynamic information of a target stereoscopic warehouse, a perspective planning for simulated monitoring of the storage dynamic information is performed in a monitoring and management area, the perspective space position, perspective space angle and perspective focal length are determined, and then a monitoring perspective window is generated according to the perspective space position, perspective space angle and perspective focal length, and then a real-time dynamic analysis is performed based on the storage dynamic information to determine the storage dynamic items passing through the monitoring perspective window.

[0110] It is understandable that warehouse dynamic information mainly records the real-time location information of items in the state of entering or leaving the warehouse.

[0111] Specifically, Figure 4 A flow chart of simulation monitoring planning in the method provided by an embodiment of the present invention is shown.

[0112] Among them, in the preferred embodiment provided by the present invention, the acquisition of storage dynamic information of the target stereoscopic warehouse, the simulation monitoring planning of the storage dynamic information in the monitoring management area, the generation of the monitoring view window, and the determination of storage dynamic items specifically include the following steps:

[0113] Step S1031, obtaining storage dynamic information of the target three-dimensional warehouse;

[0114] Step S1032: In the monitoring management area, simulate monitoring planning is performed on the warehouse dynamic information to determine the viewing angle space position, viewing angle space angle and viewing angle focal length;

[0115] Step S1033, generating a monitoring viewing angle window according to the viewing angle space position, the viewing angle space angle and the viewing angle focal length;

[0116] Step S1034: Determine the dynamic warehouse items passing through the monitoring view window according to the warehouse dynamic information.

[0117] Furthermore, the three-dimensional simulation management method of the intelligent stereoscopic warehouse also includes the following steps:

[0118] Step S104: Select a target basic model and a target simplified model corresponding to the dynamic warehouse item from the multiple item basic models and the multiple item simplified models.

[0119] In an embodiment of the present invention, a target item type of dynamic storage items is determined from multiple storage item types, and then according to the target item type, a corresponding target basic model is selected from multiple item basic models, and a corresponding target simplified model is selected from multiple item simplified models.

[0120] Specifically, Figure 5 A flowchart of selecting a target basic model and a target simplified model in the method provided by an embodiment of the present invention is shown.

[0121] Among them, in the preferred embodiment provided by the present invention, the selecting of the target basic model and the target simplified model corresponding to the dynamic storage item from the multiple basic item models and the multiple simplified item models specifically comprises the following steps:

[0122] Step S1041, determining the target item type of the dynamic storage item from the multiple storage item types;

[0123] Step S1042: selecting a corresponding target basic model from a plurality of the object basic models according to the target object type;

[0124] Step S1043: Select a corresponding target simplified model from the plurality of simplified models of the object according to the target object type.

[0125] Furthermore, the three-dimensional simulation management method of the intelligent stereoscopic warehouse also includes the following steps:

[0126] Step S105: generating a simulation management screen of the monitoring view window in real time, performing screen ratio analysis and comparison on the simulation management screen, and selecting a target basic model or a target simplified model for simulation display.

[0127] In an embodiment of the present invention, when a dynamic warehouse item passes through a monitoring perspective window, a simulation management screen of the monitoring perspective window is generated in real time based on a preset item standard model. The simulation management screen is analyzed to calculate the screen ratio of the item standard model in the simulation management screen, and the screen ratio is compared with a preset ratio threshold. According to different comparison results, a target basic model or a target simplified model is selected for simulation display. Specifically: when the screen ratio is greater than the ratio threshold, in the simulation management screen, the item standard model is replaced and optimized by the target basic model, and a simulation display is performed; when the screen ratio is not greater than the ratio threshold, in the simulation management screen, the item standard model is replaced and optimized by the target simplified model, and a simulation display is performed, so that different simulation display processing can be performed according to different situations.

[0128] It can be understood that the standard model of the item is a three-dimensional model that is suitable for all types of stored items and does not display appearance details. In the embodiment of the present invention, it can be a rectangular parallelepiped.

[0129] It can be understood that the simulation management screen includes not only the simulation of dynamic storage items, but also the simulation of the warehouse structure, conveyor belts, robotic arms, robots, etc. of the target warehouse itself that are adapted to the dynamic storage items entering or leaving the warehouse. Therefore, in an embodiment of the present invention, when the target warehouse itself occupies too much of the screen of the simulation management screen, the simulated display of the items can be performed through the target simplified model; and when the target warehouse itself occupies a relatively small proportion of the screen, the simulated display of the items can be performed through the target basic model, thereby balancing the complexity of the screen in the simulation management screen and achieving high-quality and smooth three-dimensional simulation.

[0130] Specifically, Figure 6 A flowchart of simulation display processing in the method provided by an embodiment of the present invention is shown.

[0131] Among them, in the preferred implementation manner provided by the present invention, the real-time generation of the simulation management screen of the monitoring view window, the screen ratio analysis and comparison of the simulation management screen, and the selection of the target basic model or the target simplified model for simulation display specifically include the following steps:

[0132] Step S1051, when the dynamic storage item passes through the monitoring view window, based on a preset item standard model, a simulation management screen of the monitoring view window is generated in real time;

[0133] Step S1052: Analyze the simulation management screen and calculate the screen ratio of the standard model of the item;

[0134] Step S1053, comparing the screen proportion with a preset proportion threshold;

[0135] Step S1054: When the screen proportion is greater than the proportion threshold, in the simulation management screen, the standard model of the item is replaced and optimized by the target basic model, and a simulation display is performed;

[0136] Step S1055: When the screen proportion is not greater than the proportion threshold, in the simulation management screen, the standard model of the item is replaced and optimized by the target simplified model, and a simulation display is performed.

[0137] Furthermore, Figure 7 The application architecture diagram of the three-dimensional simulation management system of the intelligent stereoscopic warehouse provided by the embodiment of the present invention is shown.

The corresponding multiple basic vertices in the basic model are selected, and the multiple basic vertices are analyzed for association, the correlation frequency ratios corresponding to the multiple basic vertices are calculated, and the lengths of the edges formed by the adjacent basic vertices are measured, and the maximum length is selected from them. By calculating the edge weight value corresponding to each edge, the multiple edge weight values ​​are compared with the preset weight threshold, and the two basic vertices corresponding to the edge weight value greater than the weight threshold are marked as optimized vertices, so that multiple optimized vertices can be selected from each meshed basic model, and then the basic vertices other than the optimized vertices are deleted in the multiple meshed basic models, and the model is simplified with the retained multiple optimized vertices to generate multiple simplified models of items.
