Problems solved by technology

Therefore, it is very difficult to recognize the suspect's face, especially if the video image of the face occupies only a small part of the entire video screen, it will be very grainy when it is enlarged
Operators perform labor-intensive manual screenings to retrieve the desired video, which is labor-intensive

Embodiment 1

[0014] Refer to attached figure 1 A PTZ tracking video monitoring system for smoke shadow detection includes a static closed-circuit monitoring system and a PTZ smoke shadow detection camera. The closed-circuit monitoring system is composed of front-end equipment, a main control system and back-end equipment; Taiwan, monitors and alarm detectors; back-end equipment includes monitors, video distributors, screen splitters and sub-controllers. A kind of PTZ tracking video monitoring system of smoke plume shadow detection realizes PTZ tracking video monitoring through the following steps:

[0015] (1) Use the camera to capture video image data from the scene according to the smoke plume shadow;

[0016] (2) Extract relevant objects from the captured video image data through three processes of three-dimensional view calculation, object segmentation, and object recognition to obtain close-up images;

[0017] (3) Automatically detect objects of interest such as moving smoke plume s...

Abstract

A PTZ tracking video monitoring system for zoysia shadow detection comprises a static closed-circuit monitoring system and a PTZ zoysia shadow detection camera. The closed-circuit monitoring system iscomposed of a front-end device, a main control system and a rear-end device. The front-end device comprises a camera, a holder, a monitor and an alarm detector. The rear-end equipment comprises a display, a video distributor, a picture divider and a sub-controller. The PTZ tracking video monitoring system for zoysia shadow detection performs PTZ tracking and video monitoring through zoysia shadowdetection, is high in system sensitivity, and is particularly suitable for the field of safety monitoring and suspect tracking. Besides, the system and the method can generate clear close-up photos on site and execute related video retrieval, so that the labor intensity is reduced, and the retrieval time and range are greatly shortened.

Description

technical field [0001] The invention relates to a PTZ tracking video monitoring system for smoke plume shadow detection and a PTZ tracking video monitoring method thereof, relating to a video monitor and a tracking video monitoring method thereof, belonging to the field of security technology. Background technique [0002] For security monitoring and video recording, a large number of closed circuit television (CCTV) cameras are installed in various locations. Current CCTV security systems are based on uncalibrated static cameras or manually operated pan-tilt-zoom cameras. Such systems offer limited functionality and in particular can only provide passive video streams for recording or live real-time control room observations. Objects of interest cannot be detected automatically and there are no close-up images of objects of interest. Therefore, it is very difficult to recognize the suspect's face, especially if the video image of the face only occupies a small part of the...
