A Stereoscopic Infrared Active Target of CubeSat and Its Relative Pose Measurement Method

Abstract

The invention discloses a three-dimensional infrared active target of a cubesat and a relative pose measurement method thereof; the three-dimensional infrared active target is mainly composed of fiveinfrared LED lamps with the wavelength of 850 nm, wherein four of the five infrared LED lamps are coplanar, and the other one of the five infrared LED lamps is located at the center of the coplanar LED lamps and protrudes for a certain distance. The device is mainly divided into five layers of structures, namely a PCB bottom plate layer, a cylindrical sleeve ring layer, an upper cover plate layer,a sleeking layer and an uppermost stand column layer from bottom to top. The PCB bottom plate layer is used for supplying power to the SMD LED lamps; the cylindrical sleeve ring layer is used for limiting light emitted by the LED lamps in an area with a specific size, so that accurate positioning of the pattern marks is realized; the upper cover plate layer is used for providing structural support; and the light area can be corrected into a complete and regular circle by the sleeking layer. The three-dimensional infrared active target is simple in structure, small in size, light in weight andvery suitable for being used on a cubesat platform, and can achieve accurate measurement of the relative poses of space cooperation targets.

Description

technical field [0001] The invention belongs to the technical field of satellites, and in particular relates to a three-dimensional infrared active target of a cubesat and a relative pose measurement method thereof. Background technique [0002] In recent years, based on the short development cycle of CubeSat, low manufacturing cost, and less R&D costs, more and more research institutes and commercial companies have turned their attention to CubeSat, in addition to scientific research, teaching and verification of electronic products. , CubeSats are also used in a series of on-orbit services, such as the formation flight of CubeSats, the maintenance and refueling of space vehicles, and the cleaning of space junk. And this series of on-orbit services are inseparable from the vision-based navigation technology of CubeSat. Therefore, a three-dimensional infrared active target and its relative pose measurement method are proposed to solve this problem. [0003] The existing coo...
