Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to an image recognition-based antenna posture determination system and an implementation method thereof. Background technique [0002] The signal coverage of the base station antenna is closely related to the azimuth angle and downtilt angle of the antenna. Since the base station antenna is exposed to the outside for a long time, it is vulnerable to some harsh and uncontrollable external forces (such as wind, hail and other bad weather), which will cause the antenna attitude to shift, thereby affecting the signal coverage of the antenna. When the attitude of the antenna is shifted, the traditional method is to monitor it manually, because it is impossible to detect the shift of the antenna in time due to limited manpower. With the continuous advancement of information technology, some products and solutions for real-time monitoring of base station antennas have appeared o...

Problems solved by technology

[0003] In the existing method, a magnetic field sensor is used to determine the azimuth angle. This method is easily affected by the surrounding magnetic field, resulting in inaccurate measurement, and the magnetic field is different in different places. It is necessary to do magnetic field calibration before installation, which is inconvenient to install.

However, with the method of dual GPS carrier phase difference technology, it is necessary to ensure a sufficient horizontal distance between the dual GPS, otherwise the error will be large, and the cost of the dual GPS module is high, which is not suitable for large-scale applications.
