Abstract

The present disclosure provides an object recognition device and method in a multi-camera surveillance network. A target recognition device used in a surveillance network including a plurality of cameras, the target recognition device comprising: viewing angle direction estimation means for estimating the target captured by each of the two cameras in the plurality of cameras relative to the viewing angle direction of the camera; feature extraction means for extracting one or more features from images containing objects captured by each of the two cameras; and object matching means for extracting one or more features according to the Assigning weights to each of the one or more features from the viewing angle directions of the targets captured by the two cameras, and calculating the target captured by the two cameras according to the weighted one or more features to determine whether the objects photographed by the two cameras are the same object.

Description

technical field [0001] The present disclosure relates to target recognition, and in particular, to a target recognition device and method, wherein the target recognition device is used in a surveillance network including a plurality of cameras. Background technique [0002] In a monitoring network including multiple cameras, how to obtain the monitoring information of a certain target and all associated cameras is a hot issue in large-scale intelligent monitoring systems at present. For example, in a building monitoring system, when a room is burglarized, the monitoring personnel often hope to obtain historical images of other monitoring cameras of the suspect in the entire building. In some monitoring systems, it is necessary to check one by one by manual search, which takes a lot of time and manpower. [0003] There is known a method for matching the same target in different cameras based on color and texture features, in which the matching similarity between targets is c...
