Embodiment

[0019] In order to accurately detect the position of the solar panel of the space target from the image of the space target containing motion blur and noise, the embodiment of the present invention provides a detection method of the solar panel of the space target, which is applied to the observation image of the space target, such as figure 1 As shown, the method includes the following steps:

[0020] Step S101: Obtain the grayscale histogram of the space object observation image through the color channel of the space object observation image;

[0021] The observation image of the space object used in this embodiment refers to the observation image of the space object including motion blur and noise obtained by a digital imaging device. The image has motion blur and noise, and at the same time, the structure of the space target is complex and the topological structure of the components is variable, which brings great difficulties to the detection of solar panels.

Abstract

The invention provides a space target solar array detection method which is applied to a space target observation image. The method comprises the steps of getting the gray histogram of the image through the color channel of the image, getting the segmentation threshold of the image through the gray histogram of the image, segmenting the image according to the segmentation threshold to get independent components, getting the edge projection integral of the independent components through the independent components, and getting the location of an array according to the edge projection integral. Through image gray histogram segmentation threshold calculation and independent component edge projection integral matrix calculation, the location of a space target solar array can be effectively and accurately detected from a space target image containing motion blur and noise.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a detection method of a space target solar panel. Background technique [0002] In the process of short-distance space target monitoring, in addition to cataloging and identifying known targets in the database, it is more important to identify newly discovered unknown targets. The morphological characteristics and size parameters of typical parts of space targets are of great value to determine the type, state and threat degree of the target. Solar panels, as the main energy source of space targets, are ubiquitous in various types of space target structures, and are typical components of space targets. For different types of space targets, there are great differences in the number of sailboards, sailboard size, sailboard shape, the size ratio of sailboards to the main structure, and the positional relationship between sailboards and other components. The hi...
