Antenna downtilt angle measuring method based on deep instance segmentation network

Abstract

The invention discloses an antenna downtilt angle measuring method based on a deep instance segmentation network. The method comprises the following steps: shooting a full range of antenna video through an unmanned aerial vehicle; transmitting the antenna video to a server in real time, and the server measuring the antenna downtilt angle in real time through a deep learning algorithm. The deep learning algorithm comprises a feature extraction network module configured to acquire an antenna feature image. The instance segmentation module performs the following steps: directly mapping a region of interest to the feature image; dividing a candidate region into k*k units; calculating four fixed coordinate positions for determining a center point of a unit for each unit; calculating values of four fixed coordinate positions by a bilinear interpolation method; and performing a maximum pooling operation and implementing backpropagation. According to the antenna downtilt angle measuring methodbased on the deep instance segmentation network, the antenna downtilt angle is more accurate by distinguishing an antenna pixel and a background pixel of the instance segmentation module, and a convenient, safe, effective and accurate antenna measuring 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.
