In order to improve the ability of target location detection in public area surveillance video,it is necessary to design a target feature tracking and localization algorithm.A new method of target tracking and localization based on image super-resolution reconstruction is proposed.The 3 D image reconstruction model of common area surveillance video is constructed.The high resolution fusion method of edge layer is used to reconstruct the 3 D structure of public area surveillance video image data,and the key feature points of public area surveillance video are extracted.The image degradation model is used to monitor the target features of common area surveillance video data,and the linear filtering model is used to make the monitoring output image satisfy the optimal matching feature solution,which improves the ability of feature tracking for common area surveillance video data.A guided filtering method is introduced for super-resolution reconstruction of video data in common area surveillance to accurately track and locate the target features.The simulation results show that the proposed method has high accuracy,strong ability of image reconstruction and less error of normalized root mean square(RMS).
