Method and device for establishing three-dimensional reconstruction model of space moving target

Abstract

The invention discloses a method and a device for establishing a three-dimensional reconstruction model of a space moving target. The method comprises the following steps: acquiring a space monocularimage sequence of space debris or a failure satellite; adopting the trained generative adversarial network to train a spatial monocular image sequence so as to eliminate flare and shadow of each spatial monocular image in the spatial monocular image sequence, and generating a first image sequence; extracting a feature value matching relationship between each image in the first image sequence and other images through a scale invariant feature transformation method; establishing a three-dimensional model sparse point cloud of the space debris or the failure satellite according to the characteristic value matching relationship; generating a three-dimensional model grid model according to the three-dimensional model sparse point cloud, and sequentially performing grid filtering and texturing processing on the three-dimensional model grid model to obtain a three-dimensional reconstruction model of space debris or a failure satellite; according to the invention, the problem of distortion ofthe three-dimensional reconstruction model when the three-dimensional reconstruction model of the spatial moving target is reconstructed according to the spatial monocular image sequence can be solved.

Description

【Technical field】 [0001] The invention belongs to the technical field of three-dimensional reconstruction of a moving object in space, and in particular relates to a method for establishing a three-dimensional reconstruction model of a moving object in space. 【Background technique】 [0002] In space missions, in-orbit services are usually required for satellites or space station devices, such as docking of space stations, recovery of failed satellites, and removal of space debris. With the development of space technology in various countries in the world, so far, more than 6,000 spacecraft have been launched by humans, and only a small part of these spacecraft enter the atmosphere and destroy themselves. Most satellites or other artificial celestial bodies are still regarded as space junk. stuck in space orbit. [0003] The existing way of clearing space junk is generally to use mother-child satellites to clear the target. However, when using larger satellites to clear spac...
