Photoelectric stabilized platform assembly zero calibration method

Abstract

The invention relates to a photoelectric stabilized platform assembly zero calibration method comprising the steps that: an airplane assembled with a photoelectric stabilized platform is leveled; a horizontal position of a target is measured and adjusted according to a first theodolite, such that a target surface perpendicular l1 is on a same straight line with airplane plumb lines AA1 and BB1; according to the measurement of a second theodolite, the height of the second theodolite is adjusted, such that the theodolite levelly aims at an assembly reference plane of the photoelectric stabilized platform; the tilt position of the second theodolite is not changed, and the azimuth is rotated, such that the theodolite is aligned with the target surface; horizontal height of the target is adjusted, such that the theodolite is aligned with a reference line L on the target surface; the sum of average values of azimuth angle alpha and tilt angle beta is calculated; and the azimuth angle and tilt angle of the photoelectric stabilized platform are corrected into 0, such that calibration is finished. With the photoelectric stabilized platform assembly zero calibration method, photoelectric stabilized platform assembly zero can be measured and calibrated accurately and reliably. The method is suitable for calibrations of photoelectric stabilized platform and airplane zero assembly error.

Description

technical field [0001] The invention belongs to the technical field of photoelectric detection, and in particular relates to a method for calibrating the installation zero position of a photoelectric stabilization platform, which can be applied to the installation calibration of a photoelectric stabilization platform. Background technique [0002] The photoelectric stabilization platform is an optoelectronic device that integrates light, mechanics and electricity, and is composed of visible light CCD cameras, infrared thermal imaging cameras and other main photoelectric loads. The photoelectric stabilization platform uses infrared thermal imagers and CCD cameras to image the target in real time day and night, to detect and scan the target, and has functions such as automatic target tracking, manual search, target positioning, and guidance.

Problems solved by technology

[0003] The angle information output by the photoelectric stabilization platform in real time, combined with the attitude information of the aircraft, can determine the spatial position information of the target, which is convenient for guidance and positioning. There are installation errors in the horizontal zero position and pitch zero position. In order to realize the positioning and guidance functions of the photoelectric stabilized platform, it is necessary to calibrate the photoelectric stabilized platform and correct the installation error
