Embodiment Construction

[0038] The invention adopts common sensor nodes, sensor nodes equipped with GPS modules and image sensor nodes with adjustable direction to cooperate with each other to complete target tracking. Each node in the network can play its own advantages, thereby saving costs and prolonging the life of the network, and can complete the tracking of the target in real time.

[0039] The target tracking method in the wireless multimedia sensor network that the present invention proposes has the following steps:

[0040] Step 1) Node types and their functions in the network. In the network, there are mainly three types of nodes: ordinary sensor nodes, sensor nodes equipped with GPS modules, and image sensor nodes with adjustable directions. The main functions of ordinary sensor nodes are abnormal detection, Target positioning and data transmission; the main function of the sensor node equipped with the GPS module is to obtain the position of the node itself and the function of the ordina...

Abstract

The invention discloses a target tracking method for a wireless multimedia sensor network, which is mainly used for solving the target tracking problem in the wireless multimedia sensor network. The method comprises three nodes, namely a common sensor node, a sensor node provided with a GPS module and an image sensor node with adjustable direction. Due to lower cost and lower energy consumption, the common sensor node can be greatly thrown into the network and takes charge of abnormality detection, target positioning and data transmission; the sensor node provided with the GPS module has the main functions of acquiring the position of a node and serving as the common sensor node; and the image sensor node has the main function of target identification. Target tracking is finished by mutual cooperation of the three nodes, and calculation and storage of a target track are finished by a base station, so the cost is saved and the service life of the network is prolonged.

Description

technical field [0001] The invention relates to a solution method for target tracking in a wireless multimedia sensor network, mainly solving the problem of realizing target tracking through various types of sensor nodes in the wireless multimedia sensor network, and belongs to the cross field of computer network and wireless communication. Background technique [0002] Wireless Sensor Network (WSN) is known as one of the three future high-tech industries in the world. It is a self-organizing wireless network system composed of a large number of sensor nodes deployed in the monitoring area. Each sensor node in the network Collaboratively perceive, collect and process the information of sensing objects in the network coverage area, and send this information to interested users. [0003] With the development of hardware technology and the appearance of cheap CMOS cameras and microphones, a wireless multimedia sensor network (Wireless Multimedia Sensor Network, WMSN) has emerge...
