[0083] It should be noted that the VR model of the avionics hub project is a model of the completed project, and the initial VR model of the avionics hub project is specifically a model of the initial project. The preset project stage information includes the preset total number of stages and the currently selected number of stages, and the larger the avionics hub project, the larger the preset total number of stages. The construction process simulation analysis of the avionics hub project VR model and the initial VR model of the avionics hub project specifically includes analysis in combination with project safety information. The project safety information is specifically the safety space structure information of the avionics hub project model in the construction process.

By selecting different project stages, the user can conveniently and intuitively experience the construction process of the different stages of the avionics hub project, thereby having a deeper and more comprehensive understanding of the entire avionics hub project.

[0084] According to an embodiment of the present invention, the sub-model splitting of the preset engineering VR model and sending the sub-models to the VR display system for model display and user interaction is specifically as follows:

[0085] Perform spatial structure analysis on the preset engineering VR model to obtain preset spatial structure information;

[0086] Split the preset engineering VR model according to the preset key areas to obtain multiple engineering combination VR sub-models;

[0087] The engineering combination VR sub-models are sent to the VR display system in a random order for model display and user interaction.

[0088] It should be noted that the preset spatial structure information is specifically the spatial relative position information of each sub-model in the preset engineering VR model, and the preset key area is specifically the key construction area in the preset engineering VR model.

[0089] In addition, the project combination VR sub-models are sent to the VR display system in a random order for model display and user interaction. Specifically, the VR display system displays multiple project combination VR sub-models. The user first previews the model through a VR visual device and then spatially combines the project combination VR sub-models through a VR control device to obtain a complete user-defined project VR model. During the interactive operation, the user can experience the spatial structural relationship between the various sub-models in the avionics hub project. The VR visual device includes a head-mounted VR device, and the VR control device includes a VR handle device.

[0090] According to an embodiment of the present invention, the model orientation analysis is performed based on the acquired user interaction data to obtain model spatial structure information, and the model spatial structure information is compared and analyzed with the preset spatial structure information in the preset engineering VR model to obtain deviation area information, specifically:

[0091] Get user interaction data;

[0092] Combine the VR spatial structure of the project combination VR sub-models according to the user interaction data to obtain the user-set project VR model;

[0093] The structural position difference analysis is performed between the user-set engineering VR model and the preset engineering VR model to obtain the deviation structural position information.

[0094] It should be noted that the deviation area information includes information on the degree of deviation and deviation structural location information. The user interaction data specifically refers to the model's orientation and movement information obtained by the user through the VR control device. By analyzing the structural position differences between the user-defined engineering VR model and the preset engineering VR model, the present invention can efficiently analyze the locations where the user's spatial structure of the avionics hub model deviates. The deviation structural location information specifically refers to the locations where there are deviations between the user-defined engineering VR model and the preset engineering VR model.

[0095] According to an embodiment of the present invention, performing model orientation analysis based on the acquired user interaction data to obtain model spatial structure information, and performing data comparison and analysis on the model spatial structure information with preset spatial structure information in a preset engineering VR model to obtain deviation area information, further includes:

[0096] Perform model orientation analysis based on the user-set engineering VR model to obtain model spatial structure information;

[0098] The deviation structure position information, the deviation area degree information and the progress information are integrated to obtain the deviation area information.

[0099] It should be noted that this deviation area information effectively reflects the degree of deviation between the user-defined project VR model and the pre-set project VR model, further reflecting the user's understanding of the avionics hub project model. By using this deviation area information for path planning, the present invention can generate targeted roaming experience path information for the user. The VR system will use this roaming experience path information to allow the user to experience VR roaming, thereby effectively improving the user's understanding of the overall structure of the avionics hub project.

[0105] It should be noted that the analysis of the shortest distance between each location point and the optimal path analysis to obtain the preferred path information specifically involves performing the optimal path analysis using a preset path algorithm, such as, but not limited to, the Dijkstra algorithm, the PRM algorithm, the RRT algorithm, etc. The analysis of the deviation weight for each specific location point based on the deviation area degree information and the calculation of the roaming time information for each specific location point based on the deviation degree weight indicate that the greater the deviation degree of the specific location point, the greater the deviation degree weight, and the longer the roaming time for the corresponding specific location point. Furthermore, the overall roaming time in the roaming experience path information is generally a predetermined value, while the roaming time for each location point varies based on the weight.

[0106] In addition, users can use VR devices to preview VR models in multiple modes, including free flight mode, free walk mode, roaming experience mode, etc. The VR device includes a VR visual device and a VR control device.
