Monocular-principle-based six-degree-of-freedom position and attitude measuring device for measuring static balance of gyroscope

Abstract

The invention discloses a monocular-principle-based six-degree-of-freedom position and attitude measuring device for measuring the static balance of a gyroscope. The measuring device comprises an X-axis image acquisition component (10) for acquiring image information of a test sample (40) in the X-axis direction, a Y-axis image acquisition component (20) for acquiring image information of the test sample (40) in the Y-axis direction, a Z-axis image acquisition component (30) for acquiring image information of the test sample (40) in the Z-axis direction, a support frame (1) and a background plate, wherein the X-axis image acquisition component (10), the Y-axis image acquisition component (20) and the Z-axis image acquisition component (30) are arranged outside the support frame (1); and the background plate is arranged in the support frame (1). The measuring device acquires a front view, a side view and a vertical view of the test sample (40) through three cameras, and is not required to be directly contacted with the test sample, so the attitude change of the test sample cannot be interfered, and the device is extremely favorable for improving measuring accuracy.

Description

technical field [0001] The present invention relates to a statically balanced measuring device, more particularly, to a measuring device based on the monocular principle for measuring the statically balanced six-degree-of-freedom pose of a gyroscope. Background technique [0002] The working principle of the gyroscope: the direction pointed by the motion axis based on the high-speed rotating rigid body will not change relative to the inertial space when it is not affected by external forces. It can use the momentum moment of the high-speed revolving body to measure the angular motion of the housing relative to one or two axes perpendicular to the rotation axis in the inertial space. Because its detection results do not depend on external reference signals, gyroscopes play a wide and irreplaceable role in aviation, spaceflight, navigation and land autonomous navigation. [0003] The mass imbalance of the gyroscope will cause a large zero error (zero drift) in its output sign...

Problems solved by technology

The traditional static balance test is carried out manually based on the naked eye or theodolite, the accuracy is difficult to guarantee, and the production efficiency is also very low
