Real-time detection and tracking system and method for point target in satellite sequence image

Abstract

The invention discloses a real-time detection and tracking system and method for a point target in a satellite sequence image. The system comprises an image data receiving module, an image frame header detection module, a single-frame image target detection module and a sequence image association detection module, wherein the image data receiving module receives a data package of a preset N-byte length from a satellite infrared image generation system each time and caches the data package in a ring buffer region; the image frame header detection module performs position detection on an initial position and an end position of the image in the ring buffer region and caches frame image data in an image cache region; the single-frame image target detection module is used for processing the image data of the image cache region to obtain suspected target information; and the sequence image association detection module is used for associating suspected target results of multi-frame image detection in time and space, and removing noise points to obtain real target information. According to the system and the method, the module division is optimized, so that the integrity, timeliness and reliability of data processing are ensured.

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.
