A Dynamic Target Tracking Method for Surveillance Video with Coupled Geospatial Information
The identification and tracking of targets in surveillance video are important for maintaining social stabil-ity and enhancing public safety and convenience,and it also provides the basis for data analysis and intelligent ap-plications.However,its degree of coupling analysis with geospatial information is relatively low,and it is time-con-suming and laborious to only rely on observation by surveillance personnel,which does not make full use of the spatial information of surveillance video.To address this problem,a method of combining surveillance video and geospatial information is proposed to detect,identify and extract the target of interest,and map the target move-ment trajectory to the map through the mapping model from image space to geospatial space.At the same time,combining the above technologies and different application requirements,a prototype surveillance video target tracking visualization system is designed and implemented to create an interactive visualization interface,which fa-cilitates the surveillance personnel to grasp the dynamic information of the target in the surveillance area on a mac-ro level,and realizes the geospatial visualization of the surveillance target.
