System and method for video-assisted identification of mobile phone users

摘要

Methods and systems for identifying and tracking individuals in a area-of-interest that may be covered by a video surveillance subsystem and by a communication location subsystem, and a correlation system correlates the outputs of the two subsystems. The communication location subsystem may monitor communication of mobile phones. The video subsystem captures video images of the area-of-interest, and processes the video images so as to identify individuals who are present in the area. The correlation system correlates a given mobile phone with a given individual who was identified by the video subsystem as being engaged in a phone conversation. After correlating the mobile phone with the individual using the phone, the correlation system outputs correlated information regarding the phone and its user to an operator.

1. A method, comprising:
identifying a mobile communication terminal that is active in an area under surveillance by monitoring communication conducted between the mobile communication terminal and a wireless communication network; automatically identifying, in video images of the area, that an individual is engaged in a communication session using the mobile communication terminal, by using a comparison of a first image model of an individual holding a model mobile communication terminal and a second image model of an individual not holding the model mobile communication terminal, wherein image models are constructed by capturing multiple training images of individuals, wherein only a subset are holding phones near their head; and correlating the identified individual with the identified mobile communication terminal; wherein identifying the mobile communication terminal comprises extracting information regarding the mobile communication terminal from the monitored communication, wherein identifying the individual comprises extracting one or more images of the individual from the video images, and wherein correlating the individual with the mobile communication terminal comprises correlating the information regarding the mobile communication terminal with the images of the individual.
