Embodiment Construction

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0017] The embodiment of the invention discloses an evacuation method under a danger source. Such as Figure 1~3 As shown, the method includes the following steps:

[0018] Step S10: Obtain any object.

[0019] Step S20: if the object is located in the danger field of at least one danger source, obtain the first panic emotion value caused by the at least one danger source to the object at the current moment.

[0020] It should be understood that if ...

Abstract

The invention discloses an evacuation method and system under a dangerous source. The method comprises the following steps: if an object is located in a dangerous field of at least one dangerous source, obtaining a first panic emotion value of the dangerous source on the object at the current moment, a second panic emotion value of other objects on the object at the current moment, and a third panic emotion value of the object at the current moment; updating the panic emotion value of the object at the current moment according to the first panic emotion value, the second panic emotion value and the third panic emotion value of the object at the current moment and the panic emotion value of the object at the previous moment; obtaining a first speed vector of the position where the object islocated at the current moment and a first speed vector of the positions where other objects are located; determining a collision domain according to the panic emotion value and the first speed vectorof the object at the current moment and the panic emotion values and the first speed vectors of other objects; and evacuating the object according to the speed vectors except the fourth speed vectorlimited by the collision domain. According to the invention, all objects in a dangerous scene can be evacuated.

Description

technical field [0001] The invention relates to the technical field of danger avoidance, in particular to an evacuation method and system under a danger source. Background technique [0002] Existing crowd evacuation methods are generally aimed at dangerous scenarios caused by a single hazard source, focusing on analyzing the movement state and behavioral decision-making of the crowd after the danger occurs. However, the number of hazard sources in an existing hazard scenario may be more than one, and the control of hazard evacuation becomes more complicated. Even if there is only one source of hazard, the objects in the hazard scene will affect each other. The reaction behavior of any object in a dangerous scene may affect the reaction behavior of other objects. However, the prior art considers few factors for the evacuation method of the objects under the dangerous source, so that the evacuation effect is not good.
