Embodiment Construction
[0050] Below in conjunction with accompanying drawing and embodiment the preferred implementation mode of the present invention is further described:
[0051] Before the algorithm is implemented, this implementation pre-calculates the crowd simulation parameter values of each Agent individual. Determine the required personality characteristic values, and solve the corresponding crowd simulation parameters through the pseudo-inverse matrix shown in formula (10). Then it is written into the program code as the initial parameter of the Agent. This implementation generally includes three modules, crowd modeling, path planning and collision avoidance. The specific process is as follows: figure 1 As shown, in the following steps 1 to 9, these modules will be described respectively.
[0052] Step 1, establish a global grid, and add a dense grid in the bottleneck area that is prone to congestion. Calculate the density field of the scene according to the initial position and initi...
