Embodiment Construction

[0019] A DSP-based multi-target tracking method, the method includes the following sequential steps: (1) Manually delineate the monitoring area and blind area in the background of the bolt monitoring, and place the dome in the blind area; (2) The bolt and the ball The machine encodes the collected video surveillance images in real time, and transmits the video stream to the digital signal processor DSP through the network; (3) the digital signal processor DSP decodes and processes the video stream, and controls the dome machine to track the moving target in real time , and display the results to the user. like Figure 4 shown.

[0020] like Figure 4 As shown, after the digital signal processor DSP receives the video stream sent by the bolt camera and the dome camera, it decodes the video stream, uses the improved multi-target tracking method to process the video of the monitoring scene, and obtains target parameter information and PTZ parameters Information, convert these ...

Abstract

The invention relates to a multi-target tracking method based on a DSP. The method comprises the following steps in order: a monitor area and a blind area are artificially designated in a gun machine monitor background, and a ball machine is placed in the blind area; the gun machine and the ball machine carry out real-time coding on an acquired video monitor image and transmit a video stream to the digital signal processor (DSP) through a network; the digital signal processor (DSP) carries out decoding and processing on the video stream, controls the ball machine to carry out real-time tracking on a moving object and displays a result to a user. The invention also discloses a multi-target tracking system. According to the method and the system, the digital signal processor (DSP) is taken as a core of the system, a monitored video monitor image is subjected to decoding and processing, the ball machine is controlled to carry out real-time tracking on the moving object, real-time multi-target tracking is realized, and cost of the whole multi-target tracking system can be reduced.

Description

[0001] technical field [0002] The invention relates to the field of intelligent video monitoring, in particular to a DSP-based multi-target tracking method and system. [0003] Background technique [0004] With the development of digital image processing technology and the increasing demand for security protection, intelligent video technology has developed rapidly. Although the existing intelligent video technology has many advantages, its inherent disadvantages have not been fully resolved, that is, its high cost has seriously affected its application range. The root cause of the high cost of an intelligent video surveillance system is that in order to achieve a more robust and real-time intelligent video analysis algorithm, the system must use a high-performance general-purpose computer as a platform, and a general-purpose computer has a large number of peripherals and great storage capacity. These resources are not necessary in most video surveillance systems. [0...
