Device and method for rapid identification and positioning of over-the-horizon maritime moving targets based on machine vision

Abstract

The present invention discloses a machine vision based over-the-horizon marine moving object rapid identification and positioning apparatus and method. The apparatus comprises an image acquisition apparatus and an image processing apparatus, wherein the image acquisition apparatus comprises a plurality of over-the-horizon infrared cameras and a plurality of short-range infrared cameras; and the image processing camera comprises a computer and an image processing system. The over-the-horizon infrared cameras are mounted on sea islands or other platforms; each over-the-horizon infrared camera can photograph an object within a visual range in the front of the camera; the over-the-horizon infrared cameras perform photographing associatively to realize omnidirectional monitoring; the over-the-horizon infrared cameras are all connected to a host computer; the short-range infrared cameras are mounted on islands or platforms around the over-the-horizon infrared cameras; the short-range infrared cameras have adjustable view angles and are connected to a slave computer; and the host computer is in communication connection with the slave computer. According to the machine vision based over-the-horizon marine moving object rapid identification and positioning apparatus and method provided by the present invention, an over-the-horizon marine moving object can be rapidly and effectively identified and positioned in various climates.

Description

technical field [0001] The invention relates to the field of over-the-horizon maritime target positioning, in particular to a device and method for quickly identifying and locating over-the-horizon maritime moving targets based on machine vision. Background technique [0002] The over-the-horizon target tracking technology based on wireless signals has been applied in many fields, such as missile interception, military tracking, electronic navigation, sea rescue, etc. At present, radar detection is the main detection method of over-the-horizon target tracking technology, and with the development of radio and communication technology, modern radar detection technology has higher and higher tracking accuracy and real-time performance. However, high-precision radar detection systems are bound to be accompanied by high cost and high maintenance costs, and radar detection systems usually need to be equipped with large auxiliary devices, making it difficult to install concealed an...
