Embodiment Construction

[0035] Specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] The overall technical scheme of the present invention is as figure 1 shown, including the following steps:

[0037] Step 101. Obtain the spatio-temporal information of the event and the characteristic attributes of the suspected target. The spatio-temporal information of the event includes the time information and location information of the event;

[0038] Step 102: Starting from the information of the place where the incident occurred, combining the spatio-temporal information with the map system, according to the characteristic attributes of the suspected target, the activity range of the suspected target is gradually obtained through video intelligent analysis, and the trace of the suspected target is determined.

[0039] Such as figure 2 As shown, step 102 can be further decomposed into the following steps:

[0040] Ste...

Abstract

The invention provides an intelligent tracking method and a system for a suspected target. The method comprises the steps of: step A, obtaining space-time information of an event and characteristic attribute of the suspected target, wherein the space-time information of the event comprises occurrence time information and occurrence place information of the event; and step B, combining the space-time information with a map system by using the occurrence place information of the event as a starting point, and obtaining the range of activity of the suspected target step by step through video intelligent analysis according to the characteristic attribute of the suspected target so as to determine the track of the suspected target. The method is not only fast, efficient and accurate, but also saves the labor cost, so that intelligent tracking method and the system represent extremely high intelligentization.

Description

technical field [0001] The invention belongs to the technical field of detection, and more specifically relates to a method and system for realizing intelligent tracking of suspected targets based on computer technology and combining video and map technology. Background technique [0002] In today's society, video surveillance equipment has become quite popular, especially in some important places and living quarters. It may be recorded by the video surveillance equipment closest to the place where the emergency occurred, which will become important evidence for law enforcement agencies to track the suspected target or punish the murderer afterwards. In the process of case investigation, after the law enforcement agencies grasp the location and time of the incident through these monitoring equipment, they need to judge the possible departure or escape path of the suspect in a timely manner, obtain information on further developments, determine the scope of further investigat...
