Target image identification system and method

The invention discloses a target image identification system and a target image identification method. The system comprises different types of image acquisition devices, a network adaptation unit, an image comparison unit and an identification result display unit, wherein the image acquisition devices are used for acquiring images and comprise a mobile terminal, a video monitoring terminal and a network personal computer (PC) terminal; the network adaptation unit is used for receiving image data which is acquired by the image acquisition devices and transmitted through different networks and adapting and analyzing the received image data, so that the system can identify the image data from the different networks; the image comparison unit is used for comparing the image data adapted by the network adaptation unit with target image data stored in a database to judge whether the image matched with the image data exists in the database or not; and the identification result display unit generates an identification result according to a comparison result. In an image identification mode, a telecommunication network, the Internet and a monitoring video network can be integrated.
