Route planning safety assessment method for unmanned aerial vehicle

Abstract

The invention discloses a route planning safety assessment method for an unmanned aerial vehicle. The method comprises the following steps: (1) calculating the central point coordinates and principledirection semi-diameter of a bounding box according to an OBB bounding box construction algorithm; (2) calculating the covariance matrix eigenvalue and eigenvector of the OBB bounding box by using a Jacobi iterative algorithm; (3) constructing a no-fly zone and an unmanned aerial vehicle bounding box respectively, carrying out safety assessment on the route of the unmanned aerial vehicle by usinga collision detection algorithm of the bounding box, if the route of the unmanned aerial vehicle goes through the no-fly zone, the route does not meet the safety requirement. According to the method,by using the collision detection principle of the bounding box, whether the route of the unmanned aerial vehicle goes through the no-fly zone can be judged accurately, the method is safe and reliable,the resources are not wasted, and a solution is provided for the route planning safety analysis for the unmanned aerial vehicle.

Description

technical field [0001] The invention relates to a safety evaluation method for unmanned aerial vehicle route planning, belonging to the field of unmanned aerial vehicle route planning. Background technique [0002] With the development of science and technology and the improvement of people's living standards, UAVs have gradually entered people's lives. UAVs are widely used in short-distance and short-distance aerial photography, photogrammetry, remote sensing data collection, agricultural plant protection, and land surveying and mapping. Application, with the increase of the drone's battery life, it has gradually developed into a medium and large drone, and its application is also more extensive, involving power inspection, environmental monitoring, express transportation, etc. With the increase of the range of drones, it is necessary to carry out route planning for drones. In the route planning of drones, it is necessary to avoid entering the air above no-fly zones such as...

AI Technical Summary

Problems solved by technology

With the increase of the range of drones, it is necessary to carry out route planning for drones. In the route planning of drones, it is necessary to avoid entering the air above no-fly zones such as important meeting areas and important buildings. At this stage, drone flight is mainly considered. Stay away from the no-fly zone directly. Although this method can ensure that the drone is far away from the no-fly zone, and the planning is simple, it increases the range of the drone, wastes resource costs, and has too much redundancy.
