Problems solved by technology

However, due to the huge number of astronomical observation images, the workload of manual naked eye recognition is very large, time-consuming and laborious; at the same time, due to the different knowledge backgrounds and abilities of different observers, the stability of each observation and recognition results cannot be guaranteed
In addition, some relatively accurate quantitative information, such as area, center of mass (indicating the position of space objects) and moving speed, cannot be measured by human naked eye recognition alone. accomplish

Embodiment Construction

[0063] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0064] figure 1 It is a flowchart of the method of the present invention. As can be seen from the figure, the computer processing method for astronomical observation grayscale image information of the present invention to carry out target tracking, its steps are divided into:

[0065] Step 1. Image acquisition:

[0066] The astronomical observation grayscale image data is stored in a computer storage device.

[0067] Step 2. Image preprocessing:

[0068] 1. Gray scale stretching:

[0069] Because the gray distribution range corresponding to the actual observation value of the original image data is too narrow, it cannot be directly displayed and processed on the computer. Therefore, firstly, the CCD image must be stretched in grayscale, so that the actual observed value can cover the entire [0, 65536] grayscale interval, and can be well displayed. ...

Abstract

The invention discloses a method for processing astronomical observation gray image via computer to track moving objects, which comprises: storing astronomical observation gray image data into a computer memory device; preprocessing the image; recognizing image objects; and tracking the image objects. The method can automatically and intelligently process massive astronomical observation gray images via computer, to automatically recognize spatial objects as moving objects and background start objects in each image, and quantitatively calculate spatial characteristics as gray scale centroid (representing the positions of spatial objects), area, length, width and eccentricity and the like, and can combine active profile track and characteristic similarity comparison based on Snake model in observation image sequence, according to the high moving speed characteristic of spatial moving objects, to automatically and accurately recognize and track appearing spatial moving objects.

Description

technical field [0001] The invention relates to a computer intelligent processing method for astronomical observation grayscale image information, which belongs to the technical field of computer applications. Background technique [0002] At present, optical detection is the main means of astronomical monitoring. Through astronomical monitoring, the position and trajectory of suspicious moving objects (such as space debris, etc.) in space can be accurately tracked and monitored, which will greatly reduce the risk of spacecraft being damaged by collisions and the resulting huge economic losses. It is beneficial to increase the industrial added value of aerospace technology products and services, and has considerable economic and social benefits. Among them, the use of astronomical optical detection means to obtain astronomical observation charge-coupled device (CCD) grayscale image sequences in space and then monitor them. The research investment is small, the application i...
