System and method for identifying and tracking suspicious target

Abstract

The invention discloses a system for identifying and tracking a suspicious target, which is used in a computer. The computer is electrically connected with a platform controller, and the platform controller is electrically connected with an infrared light-emitting diode, a camera and an infrared phototube. The system receives images acquired by the camera, selects a moving person as the target from the images, determines positions of the target in the images at different time, generates commands according to position difference to control the platform controller to drive the camera to execute corresponding motions, in this way, the target is always in a range of viewing angle of the camera. Simultaneously, the infrared light-emitting diode generates infrared rays irradiate the target, the infrared phototube generates a pulse electric signal according to the change of light intensity of the infrared rays after penetrating through the target, and the platform controller converts the pulse electric signal into a digital signal. The system judges whether the tracked target is the suspicious target according to the frequency of the digital signal, if the target is the suspicious target, the system continues to track the tracking target. The invention further provides a method for identifying and tracking the suspicious target.

Description

technical field [0001] The invention relates to a monitoring system and method, in particular to a suspicious target identification and tracking system and method. Background technique [0002] With the application and popularization of computer systems and the rapid development of network technology, remote monitoring through electronic digital products such as cameras and computer networks has been adopted by more and more industries. Among them, cameras with automatic tracking function are especially popular. At present, cameras with automatic tracking function generally identify and track suspicious targets based on their physical characteristics. However, if a suspicious target is mixed into a crowded crowd, due to the interference of other people, it is difficult for the camera to identify and track the suspicious target based on its physical characteristics. Contents of the invention [0003] In view of the above, it is necessary to provide a suspicious target ide...
