Embodiment Construction
[0060] The specific implementation steps are as follows:
[0061] Step 1: Input and configure the corresponding three-dimensional environment information Environment, obstacle information Obstacles and exit information Exits, and construct the crowd evacuation navigation grid Navmesh, such as image 3 shown. Initialize the emotional value of individual i with speed emotional value It refers to setting the individual's emotional value to 0 at the initial moment, that is, no emotional state; the individual's emotional value is between 0 and 1 during the evacuation process, and the emotional value is greater than 0 to indicate the emotional activation state; It means that the individual is randomly assigned a walking speed of 1.3-1.5m / s at the initial moment; Figure 4 shown.
[0062] Step 2: Initialize the personality trait Ψ of individual i based on the OCEAN model i , OCEAN model describes individual personality traits as variables of five dimensions, including Openn...
