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 solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended 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 array antenna of the wireless positioning base station, so as to obtain the azimuth angle and elevation angle information of the terminal. The position of the terminal can be estimated according to the position and attitude information of multiple wireless positioning base station array antennas and the measured terminal azimuth and elevation angle.

[0060] In the pure AOA positioning of multiple wireless positioning base stations, in order...

Abstract

The invention relates to an antenna pose information measurement method, device and equipment, a medium and a program product. The method comprises the following steps: determining a first conversion parameter between a coordinate system and a rectangular coordinate system of the total station; acquiring first coordinates of a plurality of first mark points on an antenna housing of a target antenna in the total station coordinate system and second coordinates of the plurality of first mark points on the antenna housing of the target antenna in a wireless positioning base station array antenna coordinate system; determining a third coordinate of each first mark point in the rectangular coordinate system based on the first conversion parameter and the first coordinate of each first mark point; acquiring a second conversion parameter between the rectangular coordinate system and the wireless positioning base station array antenna coordinate system based on the second coordinates of the first mark points and the third coordinates of the first mark points; and determining pose information of the target antenna according to the second conversion parameter. By adopting the method, the accurate measurement of the position and the attitude of the array antenna of the wireless positioning base station can be realized.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to a method, device, equipment, 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, thereby using the arrival angle to obtain the azimuth and elevation angle information of the terminal, and then based on the position and attitude information of multiple wireless positioning base station array antennas and the measured terminal The position of the terminal can be estimated by the azimuth and elevation angles. Therefore, accurately measuring the position information and attitude information of the wireless positioning base station array antenna helps to improve the accuracy of estimating the position of the terminal. [0003] In the traditional technology, the calibration of...
