Method for measuring antenna angle of communication tower by using drone and convolutional neural network

Abstract

The invention provides a method for measuring the antenna angle of a communication tower by using a drone and a convolutional neural network. The method comprises the following steps: allowing a multi-rotor drone to fly around the communication tower in a fixed point manner in order to continuously photograph the picture of the flat antenna on the communication tower and collect the GPS information of the photographing point; automatically detecting antenna distribution areas at two sides of the longitudinal axis of the communication tower through the convolutional neural network which is designed and trained in advance, and then detecting the image serial number and the antenna position when the front side surfaces of all the antennas at two sides of the communication tower appear; automatically pairing the images of the right front side surface and the left front side surface of the antenna detected by the convolutional neural network, wherein a left front side image pair and a rightfront side image pair can be formed by every antenna; and calculating the azimuth angle of every antenna according to the GPS information of the paired left and right front side images, and obtainingthe downtilt through calculating the average value of the downtilts of the antenna in the left and right front side images. The drone and the convolutional neural network algorithm are used to outputthe angle parameters of all the antennas, and data acquisition and data processing are separated, so the measurement accuracy and the measurement efficiency are improved, and the field work difficulty is reduced.

Problems solved by technology

[0004] Problems and shortcomings of this existing technology: Both the azimuth and the downtilt angle require the drone pilot to control the drone on the spot and judge with the naked eye to stabilize the aircraft on the vertical angle of the base station or antenna before shooting. Judgment of the center point Due to the large area on the front of the antenna, it is difficult to determine the actual center point with the naked eye in actual operation

[0005] To sum up, the disclosed technical solution of Chinese Patent Publication No. CN106454879A "A Method for Determining Wireless Base Station Work Parameters Based on UAV Aerial Photography" has high technical requirements for UAV pilots, and at the same time, the error of naked eye calibration is large. Pilots need to concentrate on hand-eye coordination during work, and it is difficult to perform long-term operations

According to practical tests, the efficiency in actual work is even lower than that of traditional manual operation on the tower
