Embodiment Construction

[0024] like figure 1 and Figure 5 As shown, the present invention consists of a simulation calculation subsystem 1 (1), a simulation calculation subsystem 2 (2), a scene reference map database (3), a 6-DOF robotic arm subsystem (4), and a camera subsystem (5). It is composed of a large-screen projection subsystem (6), and the simulation computing subsystem 1 (1) transfers the scene reference map in the scene reference map database (3), and uses the matching area selection and track planning software to generate matching area data. and track data, including the position of the track, the size of the matching area, the position of the matching area and the resolution data of the reference map, send these data and the flight speed of the aircraft (set through the man-machine interface) to the simulation computing subsystem through the network 2(2), the simulation computing subsystem 2(2) controls the scrolling speed of the scene reference graph and projects it on the large scre...

Abstract

The invention relates to a scene matching semi-physical simulation system based on a mechanical arm with six degree of freedom, consisting of hardware systems such as a simulation calculation sub-system, a mechanical arm sub-system with six degree of freedom, a photographing sub-system and a large-screen projection sub-system, and a scene reference map database, a scene matching software, a matching area selecting and a flight path planning software, and a relevant software of a mechanical arm motion model for simulating flight attitude. The actual work process of scene matching is simulated by using the mechanical arm with six degree of freedom, a camera, a large-screen projector and a mechanical arm motion model; a common PC is adopted as a simulation computer; the matching area selecting and the flight path planning software generates matching area data and orbit data; the dynamic characteristics of the system is accomplished by utilizing the mechanical arm motion model and the large-screen projector; the main errors (illumination and smoke) of the system are simulated by controlling the turning-on and turning-off of a fluorescent lamp; and the collection of real-time images, the control of the mechanical arm, the control of the projection speed, and a matching calculation are accomplished in the simulation computer, thus accomplishing the scene matching semi-physical simulation system. The system truly simulates the actual work process and the error of the scene matching, and the experimental result has significant meaning to the research and manufacture and the applications of scene matching engineering samples and can replace the flight-test experimental process in the actual research and development process, thus greatly improving the research and manufacture efficiency, lowering the research and manufacture cost, and having significant economic value and popularization value.

Description

technical field [0001] The invention relates to a semi-physical simulation system, in particular to a scene-matching semi-physical simulation system based on a 6-degree-of-freedom mechanical arm, which completes the semi-physical simulation of a scene matching navigation and positioning system, and is suitable for a geophysical field navigation system (including Terrain Aided Navigation System). Background technique [0002] Navigation technology has been widely used in military and civilian fields, such as aviation, aerospace, medicine, transportation, robotics and so on. In the process of theoretical research, system design and practical application of navigation technology, system simulation is an essential link. Simulation technology has high scientific value and can save research and development costs. Among them, semi-physical simulation technology has the characteristics of connecting the previous and the next, and it is a transitional process from theoretical resear...
