An Antenna Downtilt Measurement Method Based on Deep Instance Segmentation Network

Abstract

The invention discloses an antenna downtilt angle measurement method based on a deep instance segmentation network, which includes the following steps: taking a full-range antenna video by a drone; transmitting the antenna video to a server in real time, and the server measures the antenna in real time through a deep learning algorithm Downtilt; the deep learning algorithm includes: a feature extraction network module for obtaining antenna feature images; the instance segmentation module includes the following steps: the region of interest is directly mapped to the feature map; the candidate region is divided into k*k units , calculate the four fixed coordinate positions used to determine the center point of the unit for each unit, and calculate the values ​​of the four fixed coordinate positions by bilinear interpolation; perform the maximum pooling operation and realize backpropagation. By distinguishing antenna pixels and background pixels through the instance segmentation module, the downtilt angle of the antenna is more accurate, and a convenient, safe, effective and accurate antenna measurement method is established.

Description

technical field [0001] The invention relates to the field of communication measurement, in particular to an antenna downtilt angle measurement method based on a deep instance segmentation network. Background technique [0002] In the field of communication, it is often necessary to adjust the downtilt angle of the antenna. The downtilt angle of the antenna is one of the important parameters to determine the signal coverage of the base station. It is not only necessary to accurately design the downtilt angle of each antenna in the initial stage of network planning, but after the base station is put into operation, with the development of services, changes in users and the surrounding signal environment The change also needs to make accurate adjustments to the downtilt angle. [0003] At present, an inclinometer is generally used to measure the mechanical downtilt angle of the base station antenna. When using the inclinometer to measure the mechanical downtilt angle of the an...

Problems solved by technology

However, the installation of sensors is not only time-consuming and costly, but also there are differences between old and new towers, and the number and number of base station towers. Therefore, this method is not practical, and the operation period is long, making it difficult to implement.
