A method and system for automatically measuring base station antenna parameters

Abstract

A method and system for automatically measuring base station antenna parameters, comprising: a flight acquisition device takes the base station pole as a dot and flies for a circle, and streams the collected video to the antenna parameter measurement device; the antenna parameter measurement device inputs the video stream into the target tracking analysis Model, output all tracked antenna target information; continue to input the antenna target information of each antenna target into the target screenshot screening model, and output all target screenshots of each antenna target in the process of frontal side->frontal->frontal side A target screenshot sequence is formed; then each target screenshot in the target screenshot sequence of each antenna target is input to the target contour fitting model, and the contour information of the antenna target in each target screenshot is output; according to each antenna target All target screenshots and contour information in the target screenshot sequence, and calculate the parameters of each antenna target. The invention belongs to the field of information technology and can effectively improve the precision of automatic measurement and avoid external interference.

Description

technical field [0001] The invention relates to a method and system for automatically measuring base station antenna parameters, belonging to the field of information technology. Background technique [0002] In the process of putting the base station into use, due to the influence of factors such as bad weather, poor engineering quality or improper maintenance, it is easy to cause the coverage of the base station to change, resulting in a certain range of communication blind spots and an increase in the drop rate, which directly affects communication. the quality of. [0003] The main parameters that affect the coverage of the base station include the direction angle of the antenna, the mechanical inclination angle and the hanging height. For the inspection of these parameters of the antenna, the tower engineer survey is currently the main method. higher cost. [0004] Patent application CN 201811126647.3 (application name: a method for measuring base station antenna engi...

Problems solved by technology

There are two problems in this technical solution: 1) The front profile and side profile of the antenna in the image are extracted by grayscale and binarization operations. Although the area where the antenna is located is tracked using the meanShift algorithm, there are still many interferences in this area The background information of the background information, the closer the interference to the antenna, the greater the impact on the contour extraction, resulting in low measurement accuracy; 2) The RGB pixel information on the contour image is used as the clustering data of the Kmeans algorithm for clustering. The RGB information on the network is easily affected by light and weather and is unreliable, so the feasibility of this technical solution is poor
