Abstract:

In the field of antenna engineering parameter calibration for indoor communication base stations, traditional methods suffer from issues such as low efficiency, poor accuracy, and limited applicability to indoor scenarios. To address these problems, a high-precision and high-efficiency indoor base station parameter calibration method based on laser measurement is proposed. We use a high-precision laser tracker to measure and determine the coordinate system transformation relationship, and further obtain the coordinates and attitude of the base station. In addition, we propose a simple calibration method based on point cloud fitting for specific scenes. Simulation results show that using common commercial laser trackers, we can achieve a coordinate correction accuracy of 1 cm and an angle correction accuracy of 0.25°, which is sufficient to meet the needs of wireless positioning.
