Abstract

The invention relates to the field of unmanned aerial vehicle route inspection, and provides an unmanned aerial vehicle image-based established route ground object identification and positioning method, which comprises the following steps of: constructing an unmanned aerial vehicle image detection segmentation data set; constructing a potential region search model; constructing a detection segmentation model based on the high-definition image; generating route positioning and safety early warning; after threat target positioning segmentation is completed, obtaining corresponding network parameters, inputting new unmanned aerial vehicle images into the detection segmentation device, generating corresponding annotation images, utilizing the unmanned aerial vehicle attitude information corresponding to each image to draw a corresponding air route, calculating the distance between the air route and a target, and an alarm is given to the target with the height within the range of H meters.By adopting the positioning method provided by the invention, the threat target is segmented by using the detection segmentation technology, the air route is marked in the graph by using the pose information, the actual distance between the target object and the air route is calculated, safety early warning is carried out, and the positioning accuracy is high.
