Unmanned aerial vehicle route planning method and device and computer equipment

Abstract

The invention discloses an unmanned aerial vehicle route planning method and device and computer equipment, and the method comprises the steps: obtaining image data of a target region, the image data of the target region comprising surface topographic data and structure data; obtaining an initial route of the unmanned aerial vehicle based on the image data of the target area; extracting a first actual geographic coordinate of the initial route based on the inflection point position on the initial route, and adjusting the first actual geographic coordinate based on the elevation value of the surface topographic data to obtain a first elevation coordinate; adjusting the initial route based on the first elevation coordinate to obtain a terrain route; dividing the initial route into intervals according to a preset distance, and extracting a second actual geographic coordinate of an end point of each interval point by point; adjusting the second actual geographic coordinate based on the structure data to obtain a second elevation coordinate; adjusting the initial route based on the second elevation coordinate to obtain a structure route; and obtaining a final route based on the terrain route and the structure route.

Description

technical field [0001] The invention relates to the technical field of UAV route planning, in particular to a UAV route planning method, device and computer equipment. Background technique [0002] UAVs have more and more application scenarios. In the process of natural disaster risk survey, it is necessary to collect massive data of disaster-affected bodies on-site, and collect photos, videos and other related information of disaster-affected bodies. Among them, the data acquisition and obstacle avoidance of drones in densely built areas is a key research issue. The image data collection of natural disaster target areas has the characteristics of relatively simple and unified data specifications. Real-time positioning and collection of photos of disaster-affected bodies is a professional application scenario for UAVs. [0003] Most of the existing data collection UAV line inspection and obstacle avoidance methods use laser radar, ultrasonic and other methods. The cost of U...
