Abstract: A double attention network (DANet)-based drone patrol and inspection system for coastline floating garbage, including: an image acquisition module configured to shoot a video of a coastline in need of patrol and inspection by using a drone, and obtain an image from the video; a feature extraction module configured to extract shallow features and deep features, fuse the shallow features and the deep features to obtain a shared feature, and finally output a panoramic recognition result; a network training module configured to perform training on the labeled image so that the network can recognize the coastline and floating garbage; and a path correction module configured to adjust a flying direction of the drone.

Abstract: Disclosed is a method for measuring an antenna downtilt based on a multi-scale detection algorithm, including: capturing an image of an antenna using an unmanned aerial vehicle, and returning data to a server in real time; obtaining a ground truth box where the antenna is located by performing the multi-scale detection algorithm of a server; segmenting the ground truth box based on an antenna target segmentation algorithm of the server; and obtaining an antenna downtilt angle based on an antenna downtilt measurement algorithm of the server and determining whether the antenna properly functions. This method avoids the danger of tower worker climbing, is fast and accurate, saves labor costs and time, and ensures the measurement of an antenna downtilt to be smoother.

Abstract: A method and system for mobile communication base station antenna measurement is disclosed. The method comprises steps of: acquiring a set of images containing antennas of a base station; processing the set of images with a model based on instance segmentation network, and generating visualized images corresponding to the set of images of antennas; calculating, from the visualized images, the quantity of antennas of the base station and separating data for each antenna; measuring parameters of each antenna by data fitting. The system comprises a processor and a memory storing program instructions thereon, the program instructions executable by the processor to cause the system to perform the steps of the method.
