Smart camera network system and camera network dynamic task allocation method

Abstract

The invention provides a smart camera network system and dynamic task allocation method. The smart camera network system comprises a smart camera network which monitors intersection information, a management center which stores the operating state and analysis results of the smart camera network, and a remote configuration system which configures the node parameters and operating states of the smart camera network. When detecting a required target for the first time, a camera node establishes an active tracking task, and transmits a tracking task message in a multicast form; when receiving the tracking task message, a camera node establishes a passive tracking task; and when the tracked target enters the visual threshold range of a next camera node from the visual threshold range of a last camera node, the last camera node terminates the active tracking task, and the next camera node converts the passive tracking task of the tracked target into an active tracking task. With the smart camera network system and dynamic task allocation method of the invention adopted, multicast communication can be realized, and the problem of high cost of broadcast communication can be solved. The smart camera network system and dynamic task allocation method have the advantages of high tracking quality and excellent expansibility.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to an intelligent camera network system and a dynamic task allocation method for the camera network. Background technique [0002] In recent years, with the development of research on embedded systems and sensor networks, video front-end systems based on embedded smart cameras have been widely used in the field of intelligent transportation. Most of the existing video front-end systems adopt a centralized system architecture, and the system mainly includes a central control machine and cameras placed at various intersections. As a branch node, the intersection camera only has the function of collecting and transmitting the intersection video. The central control machine located in the background serves as the central control node. The system mainly relies on the control function of the central control node to control each branch node, and the video analysis and processing...
