Problems solved by technology

[0004] However, in the traditional technology, the position measurement accuracy of the antenna is usually at the meter level, and the attitude measurement accuracy is usually at the degree level and is easily affected by the surrounding electromagnetic environment. Therefore, the position and attitude measurement accuracy of this method cannot meet the high-precision positioning requirements.

Embodiment Construction

[0058] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0059] The wireless positioning base station can measure the angle of arrival (Angle of Arrival, AOA) of the terminal relative to the wireless positioning base station array antenna, so as to obtain the azimuth angle and pitch angle information of the terminal. The position of the terminal can be estimated according to the position and attitude information of the array antennas of the multiple wireless positioning base stations and the measured azimuth and elevation angles of the terminal.

[0060] In the pure AOA positioning of multiple wireless positioning base stati...

Abstract

The present application relates to a method, device, equipment, medium and program product for measuring antenna pose information. The method includes: determining a first transformation parameter between a total station coordinate system and a rectangular coordinate system; obtaining first coordinates of a plurality of first marking points on the radome of the target antenna in the total station coordinate system; and The second coordinates in the wireless positioning base station array antenna coordinate system; determine the third coordinates of each first marker point in the Cartesian coordinate system based on the first conversion parameter and the first coordinates of each first marker point; based on each first marker point The second coordinates of a marked point and the third coordinates of each first marked point obtain a second conversion parameter between the Cartesian coordinate system and the wireless positioning base station array antenna coordinate system; according to the second conversion parameter, determine the target antenna pose information. By adopting the method, the precise measurement of the position and attitude of the array antenna of the wireless positioning base station can be realized.

Description

technical field [0001] The present application relates to the field of antenna technology, and in particular, to a method, apparatus, device, medium and program product for measuring antenna pose information. Background technique [0002] The wireless positioning base station can measure the arrival angle of the terminal relative to the array antenna of the wireless positioning base station, so as to use the arrival angle to obtain the azimuth and pitch angle information of the terminal, and then according to the position and attitude information of the array antennas of multiple wireless positioning base stations and the measured terminal The azimuth and elevation angles of the terminal can be estimated. Therefore, accurate measurement of the position information and attitude information of the wireless positioning base station array antenna helps to improve the accuracy of estimating the terminal position. [0003] In traditional technologies, the position of the wireless...
