Embodiment Construction

[0055] The inertial state of the photoelectric turntable is an important working mode when the UAV performs combat missions. It is mainly used to isolate the influence of the angular movement of the UAV on the camera / infrared instrument / laser rangefinder / laser designator / optical sighting device. , keep the field of view relatively stable in inertial space, which is conducive to the combat use of UAV photoelectric reconnaissance / target tracking / weapon aiming. The present invention focuses on solving the digital function modeling problem of the photoelectric turntable's inertial working state, does not purchase the physical equipment of the photoelectric turntable, and only uses computer software simulation to realize the hardware isolation angular motion and inertial space stabilization functions of the photoelectric turntable. The technical problems to be solved by the invention include the abstract modeling of the operation level function of the installed photoelectric turntab...

Abstract

The invention discloses an inertial state modeling and simulation method of an unmanned onboard photoelectric stabilization rotary table. The inertial state modeling and simulation method comprises the steps of firstly carrying out abstracted functional modeling on a photoelectric rotary table; and then utilizing model azimuth angles and model elevation angles calculated by a visual axis inertia stable recursive iteration algorithm. According to the invention, a two-degree of freedom functional model of the photoelectric rotary table is constructed, the visual axis inertia stable recursive iteration algorithm is realized, the problems of functional modeling and inertial state algorithm modeling of a three-dimensional visual simulation photoelectric rotary table are well solved, and good project availability is achieved.

Description

technical field [0001] The invention relates to the field of modeling and simulation methods, in particular to an inertial state modeling and simulation method for an unmanned aerial vehicle-mounted photoelectric stabilized turntable. Background technique [0002] The UAV-mounted photoelectric stabilized turntable (referred to as the photoelectric turntable) is the carrying mechanism of the visible light camera, forward-looking infrared instrument, laser range finder, laser pointer, and optically stabilized aiming equipment. High-tech precision equipment that realizes the attitude adaptive control function. During the flight training of the UAV troops, the officers and soldiers found that during the reconnaissance mission of the photoelectric turntable, due to the influence of factors such as weather visibility and the high altitude of the UAV, the operation process is very complicated, and the operator’s technical proficiency is required. It is highly dependent on the actu...
