Abstract

The invention, which relates to the field of high-precision positioning, discloses a method for testing the positioning capability of a high-precision positioning terminal. The method comprises the following steps: acquiring positioning data of a positioning terminal at an original point; moving the positioning terminal from the original point to an end point along a test path, enabling the original point and the end point to be points located at the same position; acquiring positioning data of the positioning terminal at the end point; and calculating an error between the positioning data ofthe positioning terminal at the original point and the positioning data at the terminal point. The method does not need to depend on a reference terminal and does not need to be tested in a static scene when an intra-image conforming precision test is carried out; a problem of testing in a dynamic shielded scene is effectively solved, and the evaluation of the positioning capability of the positioning terminal is more accurate.

Description

technical field [0001] The invention relates to the technical field of high-precision positioning, and discloses a method and system for testing the positioning capability of a high-precision positioning terminal. Background technique [0002] In order to evaluate the high-precision positioning capabilities of various hardware positioning terminals and test the reliability of various terminals in high-precision positioning, so that the products can be applied to actual application scenarios and improve user experience, there are two commonly used measurement methods: [0003] One is to measure the internal coincidence accuracy of the hardware positioning terminal, that is, after the positioning terminal is stable, the positioning data is continuously recorded for a period of time, and the position of the center point is calculated. The positioning data of each positioning terminal to be tested and the positioning data of the center point position The standard deviation (STD)...
