A system and method for real-time detection and tracking of midpoint targets in satellite sequence images

Abstract

The invention discloses a system and method for real-time detection and tracking of midpoint targets in satellite sequence images. The system includes: image data receiving module, image frame header detection module, single frame image target detection module, sequence image correlation detection module; The receiving module receives a data packet with a preset length of N bytes each time from the satellite infrared image generation system, and caches it in the ring buffer; Position detection, and buffer the frame image data into the image buffer area; the single frame image target detection module is used to process the image data in the image buffer area to obtain suspected target information; the sequence image association detection module is used to detect multiple frames of images The suspected target results are correlated in time and space, noise points are eliminated, and real target information is obtained. The invention optimizes the division of modules to ensure the integrity, real-time and reliability of data processing.

Description

technical field [0001] The invention belongs to the field of interdisciplinary science and technology combining computer, aerospace technology and image processing, and more specifically relates to a system and method for real-time detection and tracking of midpoint targets in satellite sequence images. Background technique [0002] Since the end of the 20th century, satellite detection targets have gradually become an important development direction in the aerospace field. Whether it is in the high-tech industry or in the economic field, it has extremely high strategic significance, mainly reflected in the detection of intercontinental aircraft and aerospace aircraft and other aircraft. In the process of satellite detection of moving targets, scanning cameras and staring cameras are often used to track the targets. Due to the large pixels of the imaging surface of the scanning camera and the fast imaging frequency of staring, it poses a more severe challenge to the limited...

Problems solved by technology

The traditional single-thread technology system cannot run multiple tasks at the same time. It must complete a process before responding to the user interface, causing the user interface to be unsmooth. Even some processes that could have been processed in parallel are run on the same process. Greatly increases operating costs and wastes kernel resources

Therefore, the single-threaded program framework, in the real-time operating system, is difficult to meet the real-time processing of data and the real-time response of the user interface.
