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.
