The preset distance is set by empirical values or historical data.
In the example, according to the fire information of the areas to be extinguished, K first extinguishing areas are determined from M areas to be extinguished, and K reference driving routes are determined according to the position information of the K first extinguishing areas and the second position information, so that the accuracy in determining the K reference driving routes is improved.
