According to the rational choice perspective of the perpetrators,they will most probably flee from the crime scene,destroy the criminal evidence and conceal their identity after the crime.And this process is bound to happen within a certain period of time and a certain space.Based on the crime scene,we could restore their behavior trajectories according to the video surveillance system which has recorded the suspect's activities and trajectories before and after the incident,and then analyze the time and area of activity they are to appear.The narrow concept of the Target Trajectory refers to the sum of social interaction conditions recorded on the receiving body reflecting the information exchange of the shape body in temporal and spatial movement.It takes social network analysis,information exchange,data mining and other principles as the support.At the same time,video surveillance marks personnel trajectories,vehicle trajectory,specific objects involved in the case and such things as the identity by using time sequence,space,information and other joint investigation methods to analyze video surveillance information in the target trajectory.
