Embodiment Construction

[0020] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0021] The present invention provides a method for simulating images of moving target sequences in the air based on a remote sensing platform. In order to capture moving targets in the air, we need a camera to continuously generate multiple frames of images in a relatively short period of time to reflect the moving characteristics of the target. Overall flow chart of the present invention is as figure 1 shown. Below in conjunction with accompanying drawing and example the present invention is described in further detail.

[0022] Step 1: Use the simulation software to generate a pure black base map whose length and width are respectively m*n; add the set target track to the pure black base map, and use the initial point of the target track as the current point M g ;

[0023] Generate a pure black image whose gray value is all 0. The size of the pure bla...

Abstract

The invention discloses an aerial moving target sequence image simulation method based on a remote sensing platform, which can enable features of the extracted moving target to be more real. A pure black base map is generated; an already-set target track is added to the map, and the initial point of the target track serves as the current point M<g>; a moving target template is made and a background image is selected, a point M<g+1> with a distance of V1 is selected, and the heading angle at the point M<g+1> is calculated; the moving target template is placed at the point M<g+1> and is rotated to be consistent with the heading angle at the point M<g+1> and is then saved; and the center point of the well-saved moving target template is placed at the point M<g+1> in the background image; and corresponding processing is carried out on pixels whose gray values are no smaller than 0 in the moving target template, and a simulation map sequence for the moving target can be further acquired.

Description

technical field [0001] The invention belongs to the technical fields of image processing and aerospace, and in particular relates to a method for simulating images of moving target sequences in the air based on a remote sensing platform. Background technique [0002] Remote sensing image simulation is a technology that uses computer simulation to generate real visible light scene images. Because it is widely used in national defense, military, aerospace and other fields, it has received more and more attention from domestic and foreign personnel. With the continuous update of computer hardware and the development of computer graphics, the use of computer simulation to generate visible light scene images has become an important channel for obtaining original images. Visible light scene images generated by computer simulation can be used as the original image input of simulation systems such as visible light imaging guidance, thereby reducing the research and development cost...
