Problems solved by technology

[0003] However, the current personnel classification methods are either limited and can only be applied to a single scene, such as only identifying a single type of office workers or drug dealers, or they are time-sensitive. The recognition algorithm is no longer applicable
[0004] To sum up, there is still a lack of effective solutions for how to identify the degree of suspicion of personnel in special places based on personnel behavior trajectory information

Abstract

The invention discloses a method and device for identifying suspected person of a special place. The method comprises the following steps of: selecting a plurality of different types of case places and case time period thereof; collecting individuals and behavior tracks thereof appearing in all cases, and establishing a behavior track library; retrieving individuals appearing in each case place inthe case time period from the behavior track library; performing cross collision analysis on the behavior track of the retrieved individual so as to select a suspected person; and calculating the suspect probability of the suspected person. According to the method and device for identifying suspected person of a special place, the suspected person is selected by carrying out retrieval and cross collision analysis on the individuals appearing in case place in the case time period, and the suspect probability of the suspected person is calculated, and field guidance can be provided for public security officer to key investigations.

Description

technical field [0001] The invention relates to a method for identifying a suspect, in particular to a method and device for identifying a suspect in a special place. Background technique [0002] With the support of the increasingly rapid development of information technology, the use of information technology to control key personnel such as criminals and fugitives has become an important research direction of public security organs. During the daily activities of key personnel, the data information of various behavior records generated records the action trajectory and direction of key personnel. Therefore, it is particularly important to use the dynamic trajectory of personnel to analyze the types of key personnel and improve the research and judgment efficiency of public security intelligence personnel. [0003] However, the current personnel classification methods are either limited and can only be applied to a single scene, such as only identifying a single type of o...
