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 non-linear direction line tracking algorithm of the photoelectric turntable.

[0054] 1. Abstract functional modeling of photoelectric turntable:

[0055] The installed photoelectric turntable is a two-axis four-frame hardware, which is composed of a mechanical servo structure, a gyro stabilization structure and an image controller adaptive control structure. The present invention simplifies it into a two-axis two-frame structure (referred to as a functional model) in terms of function. ,Such as figure 1 As shown, it consists of an inner ring assembly, an outer ring assembly and a support. The inner ring assembly is installed at the viewpoint (including camera / forward-looking infrared device / laser pointer / sighter / optical aiming device, the virtual optical axis of the viewpoint is simply referred to as the model line of sight), ...

Abstract

The invention discloses a modeling and simulation method of a tracking mode of an unmanned aerial opto-electronic stabilizing turntable. The opto-electronic stabilizing turntable tracking function is achieved on the base of digital modeling algorithm simulation, and the method is used for three-dimensional virtual simulation training of the unmanned aerial vehicle equipment which carries the opto-electronic stabilizing turntable or theoretic verification of the new opto-electronic stabilizing turntable. The modeling and simulation method mainly includes a functional modeling of the opto-electronic turntable and nonlinear direction line tracking algorithm realization of the opto-electronic turntable. According to the modeling and simulation method, a two-freedom functional model is constructed to realize the nonlinear direction line tracking algorithm. The modeling and simulation method solves the modeling problems of the functional modeling and the tracking algorithm modeling of the opto-electronic turntable of a three-dimensional visual simulation test, and has a good engineering availability.

Description

technical field [0001] The invention relates to the field of simulation algorithms for unmanned aerial vehicle platforms, in particular to a tracking state modeling and simulation method for an unmanned aerial vehicle-mounted photoelectric stabilized turntable. Background technique [0002] The UAV-mounted day and night photoelectric stabilized turntable (referred to as the photoelectric turntable) is the carrying mechanism of the visible light camera, the forward-looking infrared instrument, the laser rangefinder / indicator, and the optically stable aiming equipment. High-tech precision equipment adapted to realize the attitude control function. During the equipment flight training, the officers and soldiers of the unmanned aerial vehicle found that the tracking operation process of the ground target when the photoelectric turntable is in the tracking state is very complicated due to the influence of factors such as weather visibility and the high flight altitude of the unma...
