[0037] The exemplary embodiments will be described in detail herein with reference to the attached drawings; figures. The following detailed description is merely exemplary of the application and is not intended to limit the scope of the application as described in the appended claims. In the description, similar elements throughout the various figures are referred to with like reference numbers.
[0038] In an embodiment, Figure 1 is a schematic block diagram of a simulation teaching system in a virtual environment according to an exemplary embodiment, referring to Figure 1 , a simulation teaching system in a virtual environment is provided, comprising:
[0039] A virtual scene construction module 101 is configured to acquire image information of a plurality of real scenes, and construct a scene three-dimensional model corresponding to the plurality of real scenes according to the image information.
[0040] A virtual instrument construction module 102 is configured to construct a virtual instrument model according to a real instrument, and acquire a use rule of the virtual instrument model, the instrument being used for GNSS control network project production or real-time dynamic measurement.
[0041] A function selection module 103 is configured to select a corresponding running mode and a scene three-dimensional model according to a user instruction, the running mode at least including a simulation mode and a field mode.
[0042] A simulation learning module 104 is configured to perform device cognitive learning or device cognitive evaluation when the user selects the simulation mode.
[0043] A simulation operation module 105 is configured to load the scene three-dimensional model to form a virtual environment on a display screen when the user selects the field mode, load a virtual character in the virtual environment, acquire a user operation instruction, and control the virtual character according to the user operation instruction, so that the virtual character controls the virtual instrument model to perform a corresponding operation in the virtual environment.
[0044] The evaluation module 106 is configured to score the operation performed by the virtual character according to the use rules when the user selects the evaluation function in the field mode.
[0045] It can be understood that the technical solutions shown in the present application can construct a plurality of scene three-dimensional models corresponding to real scenes, virtual instrument models and use rules, and run the simulation mode or the field mode according to user instructions. The instrument is used for GNSS control network project production or real-time dynamic measurement. In the field mode, the scene three-dimensional model is loaded on the display screen to form a virtual environment, and a virtual character is loaded. The virtual character is controlled to perform corresponding operations in the virtual environment using the virtual instrument model according to the user operation instruction, and the operation performed by the virtual character is scored. The technical solutions shown in the present application imitate the real scene and the real instrument to construct the corresponding virtual scene and instrument, so that students can learn the operation and use method of the real instrument in the virtual scene, and can randomly switch the scene, without being limited by the cost, environment and other real conditions, and the teaching effect is good.
[0046] In specific practice, when constructing the environment three-dimensional model, the virtual scene construction module needs to obtain the oblique photography three-dimensional model of the real scene to build the virtual scene. The process is as follows: a multi-angle camera is carried on a UAV or other flight platform to shoot an object from multiple angles, so as to obtain image information of the object. Then, the multi-angle images are matched and spliced by means of image processing software to generate a three-dimensional model, which can truly reflect the color, texture and other detail information of the object. Finally, a modeling engineer uses a three-dimensional modeling tool to process the three-dimensional model generated by the oblique photography, and outputs a virtual scene which restores the real scene in 1:1.
[0047] In a preferred embodiment, the virtual scene construction module 101, when constructing the scene three-dimensional model, further comprises:
[0048] According to the image information of the real scene, the real scene is divided into a plurality of scene types, each scene type is independently modeled, so that each scene type has an independent geometric body, material and map; all scene types are integrated into a scene three-dimensional model, and lighting is set in the scene three-dimensional model. At the same time, large elements such as terrain and buildings are made to ensure that the scene and the real proportion are 1:1, so as to improve the sense of immersion. It also needs to be noted that detail elements such as vegetation, roads, traffic signs, manhole covers, street lamps and the like are added.
[0049] In terms of scene optimization, PBR physical materials are used to reduce the use of ordinary materials and increase the beauty and details of the scene. LOD technology is used to dynamically adjust object details based on the distance between characters and objects, reducing rendering pressure. Proper lighting is set to enhance the realism and three-dimensionality of the scene. In addition, appropriate sound effects and atmosphere elements can be added to enhance the immersion of the scene. Each element in the scene is treated in detail to ensure that the overall effect is harmonious and unified.
[0050] Taking the production of a GNSS control network project as an example, since multiple instruments are used in the production of a GNSS control network project, multiple scene three-dimensional models can be constructed. In subsequent use, the user can manually select the scene three-dimensional model they want to load to load the desired virtual scene.
[0051] When constructing the virtual instrument model, the virtual instrument construction module 102 is constructed according to the real instrument. The modeling engineer constructs the virtual instrument model in a 1:1 ratio by combining the drawings designed for the real instrument. The operating system built into the virtual instrument model also needs to be the same as that of the real instrument.
[0052] At the same time, the virtual instrument model has its corresponding usage rules, which are designed according to the usage rules of the real instrument to ensure teaching accuracy.
[0053] After constructing the scene three-dimensional model and the virtual instrument, the user can use the simulation teaching system in the virtual environment. When the user uses the system, they first need to select the function, as shown in Figure 2 Figure 2 RTK is taken as an example in
[0054] The function selection module 103 can select the corresponding running mode and scene three-dimensional model according to the user's instructions. First, the running mode selection is performed, and the running mode at least includes simulation mode and field mode.
[0055] When the simulation mode is selected, the system calls the simulation learning module 104, and the user performs device cognitive learning or device cognitive evaluation from this module. Device cognitive learning is usually to enhance the user's cognition of the basic information and usage information of the RTK device. Device cognitive evaluation is to evaluate the user's mastery of RTK device knowledge in the form of an exam. Preferably, the user's evaluation score can be obtained and submitted, and the teacher can receive the score of each user, facilitating teaching guidance.
[0056] When the field mode is selected, the learning function, practice function, or evaluation function can be further selected. The simulation operation module will execute the corresponding content display according to the user's selected function.
[0057] It should be noted that when the user selects the learning function in the field mode, the simulation operation module displays the use video of the instrument according to the user instruction. Preferably, the GNSS control network project production, single base station RTK or network RTK can be learned through the video learning mode.
[0058] It should be noted that when the user selects the practice function in the field mode, the simulation operation module loads the scene three-dimensional model on the display screen to form a virtual environment, and after loading the virtual character in the virtual environment, the virtual environment can also generate a task, and the task completion condition is generated according to the operation of the virtual character.
[0059] In specific practice, the practice mode does not need to score the operation of the user, but also needs to guide the user what to do, so as to play a role in guiding the user. Therefore, in the practice mode, a series of tasks capable of guiding the user can be generated in the display screen, and the user can operate the virtual character step by step according to the content of the task, so as to play a role in learning the use of the instrument.
[0060] When the user selects the evaluation function in the field mode, the simulation operation module loads the scene three-dimensional model on the display screen to form a virtual environment, and loads the virtual character in the virtual environment. At this time, no task will be generated, and the user can operate the virtual character freely, and at the same time, the evaluation module 106 will score the operation of the virtual character according to the use rule.
[0061] It should be noted that the use rule includes: the steps when using the real instrument, and the judgment condition corresponding to each step;
[0062] When the evaluation module scores the operation of the virtual character, it also includes: when the virtual character performs the operation, it is judged whether the operation conforms to the judgment condition corresponding to the current step, if yes, it is scored according to the preset scoring rule.
