Embodiment Construction

[0053] The invention mainly includes two parts, one is the functional modeling of the photoelectric turntable, and the other is the realization of the nonlinear direction line tracking algorithm of the photoelectric turntable.

[0054] 1. Abstract function modeling of optoelectronic turntable:

[0055] The installed photoelectric turntable is a two-axis four-frame hardware consisting of a mechanical servo structure, a gyroscope stabilization structure and an image controller adaptive control structure. The present invention functionally simplifies it into a two-axis two-frame structure (referred to as a functional model). ,like figure 1 As shown, it consists of an inner ring assembly, an outer ring assembly and a support. Inner ring component installation viewpoint (including camera / forward-looking infrared instrument / laser indicator / sighter / optical aiming device, the virtual optical axis of the viewpoint is abbreviated as the model sight axis), and the rotation axis of the i...

Abstract

The invention discloses a tracking state modeling and simulation method of an unmanned aerial vehicle-mounted photoelectric stabilized turntable, which realizes the tracking state function of a photoelectric turntable based on a digital modeling algorithm simulation, and is used for three-dimensional visual simulation training of unmanned aerial vehicles equipped with a photoelectric stabilized turntable. , or the theoretical verification of the new optoelectronic turntable, mainly includes two parts: the functional modeling of the photoelectric turntable, and the implementation of the non-linear direction line tracking algorithm of the photoelectric turntable. The invention constructs a two-degree-of-freedom functional model of the photoelectric turntable, designs and implements a nonlinear direction line tracking algorithm, and solves the functional modeling and tracking algorithm modeling problems of the photoelectric turntable for three-dimensional visual simulation testing, and has a good engineering availability.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle platform simulation algorithms, in particular to a tracking state modeling simulation method of an unmanned aerial vehicle-borne optoelectronic stable turntable. Background technique [0002] The UAV-borne day and night photoelectric stabilization turntable (referred to as photoelectric turntable) is a bearing mechanism for visible light cameras, forward-looking infrared instruments, laser ranging / indicators, and optical stabilization aiming equipment. Adapt to the high-tech precision equipment that realizes the attitude control function. During the equipment flight training, the officers and soldiers of the UAV unit found that the tracking operation process of the ground target when the photoelectric turntable was in the tracking state was very complicated due to the influence of weather visibility and the high altitude of the UAV. The technical proficiency requirements are high, and the d...
