Abstract

The invention discloses a method and system for locating a fire site based on an unmanned aerial vehicle. The method includes: obtaining data of physical markers or special buildings placed in multiple places around the fire site as markers to establish a self-defined coordinate system; Manually point out the two markers in the picture, and combine the clicked position and attitude angle to calculate the position of the drone in the self-defined coordinate system to locate the drone; according to the pictures taken by the two drones, manually point out The position of the same key point is combined with the click position, the attitude angle and the two shooting positions of the key point to calculate the position coordinates of the key point in the self-defined coordinate system to complete the positioning of the key point in the fire scene; wherein, The position of the drone is the shooting position. The invention accurately and quickly locates the fire scene, and marks key points and floors, provides intuitive scene conditions for fire site commanders, assists them in making disaster relief tactical decisions, and greatly improves efficiency.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles and fire detection, in particular to a method and system for locating fire sites based on unmanned aerial vehicles. Background technique [0002] As the saying goes: "Water and fire are merciless", the handling of fire is still a worldwide problem today. Fires are sporadic, frequent, and sudden, and the fire is easy to spread. When a fire occurs, firefighters need to investigate the fire scene as soon as possible, determine the fire situation, make tactical deployments for the on-site building structure, and look for rescue targets and rescue routes. Only when the fire commander has a comprehensive and detailed understanding of the fire situation in a timely manner can he make correct judgments and deployments to achieve the goal of controlling the spread of the fire and reducing economic losses and casualties. [0003] At present, the method of fire detection is often that the ...
