Photoelectric inertia harmonization system three-dimensional space angle measuring instrument

Abstract

A photoelectric inertia harmonization system three-dimensional space angle measuring instrument is structured as follows: the front of a front housing is provided with a measuring lens; a light source part is arranged inside the front housing; light transmission is carried out between the light source part and the measuring lens through a beam splitter prism; an image sensor is disposed inside the front housing and senses and transmits photosignals in the beam splitter prism; the upper surface of the front housing relative to the position of the beam splitter prism is provided with an alignment indicator panel; and a side surface and the bottom of the front housing and a rear housing are respectively provided with a fiber gyroscope, and data acquired by the three fiber gyroscopes is transmitted to a host computer. Through the above structure, a space angle measuring instrument which detects accurately and is convenient to operate is provided, and technical problems of low accuracy and complex operation existing in the prior art are solved.

Description

technical field [0001] The invention relates to a space angle measuring instrument, in particular to a three-dimensional space angle measuring instrument for a photoelectric inertial target calibration system. Background technique [0002] Target calibration is a kind of measurement work to calibrate airborne weapons, airborne radar and other external equipment, and measure the spatial geometric relationship between them and the absolute reference axis of the aircraft fuselage. This measurement work is mainly aimed at the relative angle relationship of three-dimensional space straight lines. At present, the traditional target calibration method is widely used in domestic aircraft calibration. Traditional target calibration requires the use of equipment such as jacks, target calibration boards, lasers, and target calibration mirrors. When calibrating the target, the laser beam emitted by the laser is used to map out the measurement axis, projected onto the target plate in fr...
