Space Debris Detection Algorithm Based on Mathematical Morphology

2009 International Conference on Artificial Intelligence and Computational Intelligence, 2009
With the space exploring, the number of the aircrafts in orbit has been increasing, and how to reduce the growth rate of space debris or detect or remove them is urgent. Therefore, the space debris detection algorithm research has become one of key technologies in space debris research. For the traditional algorithms of the target detection are limited

First optical space debris detection campaign in Italy

Advances in Space Research, 2004
Abstract In April 2002 the first dedicated observations of space debris in Italy have been performed by the Group of Astrodynamics of the University of Rome “La Sapienza”. The campaign was accomplished using one of the Campo Catino Astronomical Observatory telescopes. In the paper the campaign is described and the first results are presented.

Streak Detection for Space Debris observation

Man-made space debris orbit around the Earth at many altitudes in different orbits and many launches add further debris to already congested orbits. The ESA GSTP-funded Optical In-Situ Monitor project started in 2016 and aims to analyze the End-to-End processing pipeline from image acquisition to the extracted positions of space debris.

Detection ability of space-based optical observation system to space debris

SPIE Proceedings, 2015
For supplying the reference to the spaced-based optical observation system design and performance analysis, the space-based observation mode for space debris is established. Considering the geometry size, the material characteristics, and the distribution region of the debris, the visual magnitude of space debris is calculated in the condition of ...

Space-based detection of space debris by photometric and polarimetric characteristics

AOPC 2017: Space Optics and Earth Imaging and Space Navigation, 2017
The number of space debris has been increasing dramatically in the last few years, and is expected to increase as much in the future. As the orbital debris population grows, the risk of collision between debris and other orbital objects also grows. Therefore, space debris detection is a particularly important task for space environment security, and ...

Innovative techniques for small space debris detection

1998
The large number of man-made uncontrolled objects orbiting the Earth is becoming a serious threat to space activities. Existing models of this orbital debris population are inadequate, particularly in the debris size range between sub-millimeter and tens of centimeters.

Monte Carlo simulation of detecting space debris with lidar

SPIE Proceedings, 2010
ABSTRACT On the basis of analysis and processing of space background radiatio n, the article gives the detection probability when the lidar detecting space debris, and compare the random va riable which is produced by Monte Carlo method with the detection probability, then get the detection results. The results reveal that, the detection model can well

Microwave radar imaging and detection algorithm for space debris

2011 International Conference on Electronics, Communications and Control (ICECC), 2011
There are more than one hundred thousand space debris with the diameter beyond one centimeter, the exist of space debris has been seriously threatening the safety of the on-the-track space probes. Small space debris, diameter between one and ten centimeter, is focused as the main target in this paper, on the base of the single range matching filtering ...

Streak detection algorithm for space debris detection on optical images.

Any image processing object detection algorithm somehow tries to integrate the object light (Recognition Step) and applies statistical criteria to distinguish objects of interest from other objects or from pure background (Decision Step). There are various possibilities how these two basic steps can be realized, as can be seen in the different proposed
