Abstract

The invention relates to an attitude measurement method, which relates to the field of measurement. The attitude measurement method comprises the steps of placing binocular cameras outside an observation window, wherein the observation window is installed on the side wall of a wind tunnel test section, and the binocular cameras comprise the left camera and the right camera, placing a target outside the observation window, and calibrating internal parameters and external parameters of the binocular camera by using the target to obtain a first parameter, placing the target in the wind tunnel test section, and calibrating internal parameters and external parameters of the binocular camera by using the target to obtain second parameters, obtaining a mapping relationship between the first parameter and the second parameter, adopting a binocular camera to obtain a first attitude of a tested model according to the second parameter, wherein the tested model is arranged in the wind tunnel testsection, and obtaining a target attitude of the measured model according to the mapping relationship and the first attitude. The method is used for solving the problem of inaccurate attitude measurement caused by light refraction caused by observation window glass.

Description

technical field [0001] The present application relates to the field of measurement, in particular to an attitude measurement method. Background technique [0002] Wind tunnel test refers to an aerodynamic experimental method that places aircraft or other object models in a wind tunnel to study gas flow and its interaction with the model to understand the aerodynamic characteristics of actual aircraft or other objects. Wind tunnel tests on aircraft play an important role in the design process of contemporary aircraft. Many important parameters in the design process of aircraft, such as load distribution and model surface aerodynamic force, are obtained by wind tunnel tests. Therefore, the accuracy of wind tunnel test data directly affects the reliability of aircraft design. With the continuous development of modern technology and the continuous improvement of aircraft design technology, higher and higher requirements are put forward for the refinement of wind tunnel tests. ...
