Single baseline binocular measuring system for measuring non-cooperative targets

Abstract

The invention discloses a single baseline binocular measuring system for measuring non-cooperative targets. The single baseline binocular measuring system comprises a single baseline binocular camera, an active lighting system and a data processing computer. The active lighting system is located on the perpendicular bisector of the baseline of the single baseline binocular camera, and the lighting emission flare angle of the active lighting system is bigger than or equal to the vision angle of a single camera. The data processing computer processes the images of the single baseline binocular camera. The binocular measuring system is a non-contact type image measuring system aiming at non-cooperative targets and aims at complete non-cooperative targets or half-cooperative targets; no cooperative measurement object is installed on the measurement target; the characteristics points are picked up and the measurement is confirmed through the stereoscopic vision principle of the image of the binocular camera; the measuring system can reduce the rendezvous and docking conditions and is suitable for the capturing for rendezvous and docking of the targets which are totally unknown to each other. The binocular measuring system adopts the active lighting system to light the non-cooperative targets so as to reduce the interference to the measuring system from the stray light of the sun and to ensure the normal operation of the system without the existence of an external light source.

Description

technical field [0001] The invention relates to a non-cooperative target binocular measurement system, in particular to a single-baseline non-cooperative target binocular measurement system, which belongs to the field of non-contact visual measurement of non-cooperative targets and is applicable to the movement of non-cooperative spacecraft in the autonomous approach process The relative measurement of parameters can also be used for the relative measurement of motion parameters of non-cooperative targets on the ground at ultra-short distance. Background technique [0002] In autonomous spacecraft rendezvous and docking missions, optical imaging sensors are currently used internationally to measure the relative position and attitude of targets within a distance of tens of meters before docking. Therefore, it is necessary to install marker lights or reflectors on the target spacecraft, install measuring equipment on the rendezvous spacecraft to measure them, establish the tar...

Problems solved by technology

[0003] however, for non-cooperative targets, that is, without any pre-installed markers, to achieve the rendezvous and docking mentioned above, it is not possible to use some spatially distributed marker lights or known measurement objects such as reflectors as reference targets

For the rendezvous and docking measurement of non-cooperative targets, in order to make the measurement system cover the measurement range of tens of meters to submeters, aerospace is still exploring in this technical field, and there is no very mature technology
