Problems solved by technology

As a result, the picture is not continuous and affects the visual effect
[0006] 2) The display magnification of the image is unreasonable, resulting in insufficient target information and easy loss of the target
[0007] 3) The behavior analysis and detection scene of the ball machine is single, and the advantage of the ball machine without blind spot monitoring is not fully utilized

Abstract

The invention discloses a method and a device for realizing monitoring by a fast ball tracking system. The method comprises the following steps: obtaining the PT value of each frame of a monitored target at the preset frame rate after the initialization operation is completed and the monitored target is detected; differencing the latest PT value and the former PT value; and controlling the operation of a ball machine according to differencing results. By applying the invention and adopting 3D based positioning principle, the better tracking on the conditions of tiny movement or even still standing of moving targets can be obtained through the control algorithm of the target speed, and the defect of discontinuous tracking can be effectively overcome. Through magnification closed-loop control, rich information of the target can be obtained, and tracking locking can be perfectly realized. The cruising tracking function provided by the embodiment of the invention can realize the alternatecruising detection tracking among a plurality of scenes, and the advantage of blind-area-free monitoring of the ball machine can be realized.

Description

technical field [0001] The invention relates to the technical field of monitoring, in particular to a method and device for realizing monitoring by using a dome tracking system. Background technique [0002] With the further development of artificial intelligence technology and computer technology and the increasing demand for "safety" of human beings, the intelligent monitoring system that can expand the scope of human vision and replace or partially replace human beings in monitoring activities has attracted more and more attention. The intelligent video surveillance system uses computer image processing technology to analyze and understand the video signal collected by the camera, and based on this, it controls the video surveillance system so that it has the intelligence of a human brain. The intelligent video surveillance system mainly completes the following functions: 1) Use computer vision technology to automatically detect suspicious targets (moving targets or prede...
