Embodiment 1

[0026] Such as figure 1 and figure 2 As shown, an automatic addressing method for complex terrain includes the following steps:

[0027] (1) Establish the node model of the tree; use the UAV or robot to move in the target area and carry the positioning module to create and connect each inflection point, fork and dead end exit point that the UAV or robot passes through as a node , get a dendrogram;

[0028] (2) Identify nodes; the positioning module can be used outdoors to record the coordinate system. When the positioning module has no signal or the signal is weak, it can establish a coordinate system based on the detected distance to uniquely identify each node and compare the front, back, left, and right distances of each node with each node. Has the road in the direction been marked?

[0029] (3) Determine the direction of movement;

[0030] Go forward when there are no obstacles in front and you have not passed through; judge to the left when the front is not satisfie...

Abstract

The invention discloses an automatic addressing method for complex terrain, which relates to the technical fields of firefighting and rescue. It includes the steps of establishing a node model of a tree, identifying nodes, judging the moving direction, and re-planning the route. The invention adopts distance measurement and obstacle avoidance. The technical solution enables drones or robots to search and plan paths in complex terrain (mines, construction buildings, etc.) without a GPS signal indoors, and automatically find and monitor paths, replacing manual operations in some complex terrain environments. Operations (dangerous, narrow, complex, unknown areas) can avoid casualties and improve operation efficiency and intelligence.

Description

technical field [0001] The invention relates to the technical field of fire fighting and rescue, in particular to an automatic addressing method for complex terrain. Background technique [0002] UAVs and robots can replace manual operations in some complex terrain environments, such as automatic exploration, search and rescue of mines, automatic inspection of road and railway power lines, automatic inspection of underground water pipes and building vents, etc. application in many fields. However, the existing inspection operations using drones or robots generally rely on the command center to remotely control the operation path. However, in some special environments such as indoors, mines, and underground pipelines, the GPS signal is weak or absent, and drones are needed. Or robots can automatically avoid obstacles and plan paths in real time. The current automatic tracking and obstacle avoidance does not combine the idea of ​​trees into complex environments, and has not b...
