the path planning module is used for taking the virtual position point of the animated character as a fire point, taking the preset distance difference between the fire point and the virtual position, the fire spreading direction, the smoke spreading and the barrier position as influencing factors, taking the outlet point as an end point, and generating and marking an escape route in the three-dimensional model based on a preset path planning algorithm;
and the third generation module is used for generating video information of the animated character moving along the escape route and sending the video information to a user terminal so as to instruct the user terminal to play the video information to a user.
6. The fire escape simulation device according to claim 5, wherein the acquisition module includes:
the acquisition sub-module is used for acquiring an image to be processed; the image to be processed is obtained by shooting a scene to be checked by a depth camera;
the generation sub-module is used for generating a point cloud according to the image to be processed;
and the processing sub-module is used for processing the point cloud to obtain a three-dimensional model.
7. The fire escape simulation device of claim 6, wherein the processing sub-module comprises:
a smoothing unit, configured to smooth the point cloud;
and the geometric recovery unit is used for carrying out geometric structure recovery on the point cloud after the smoothing treatment to obtain a three-dimensional model.
8. The fire escape simulation device according to claim 5, wherein the device further comprises:
and the determining module is used for determining the target object in the three-dimensional model.
9. A server comprising a memory, a processor and a computer program stored in the memory and executable on the processor, wherein the processor implements the method of any of claims 1 to 4 when executing the computer program.
10. A computer readable storage medium storing a computer program, characterized in that the computer program when executed by a processor implements the method according to any one of claims 1 to 4.
