Automatic face tracking three-dimensional imaging system, imaging method and imaging equipment

Abstract

The invention discloses an automatic face tracking three-dimensional imaging system, imaging method and imaging equipment. The system comprises a video acquisition unit, a data exchange unit, a central control server and a three-dimensional imaging unit, and the central control server comprises a target person locking unit, a target person positioning unit and a face recognition unit; the data exchange unit is used for combining the video streams acquired by the video acquisition unit into a live video stream; the target person locking unit is used for locking a target person meeting a presetrequirement from the live video stream, the target person positioning unit is used for determining position information of the target person, and the face recognition unit is used for extracting feature information of the target person; and the three-dimensional imaging unit is used for displaying the position information, the feature information and the tracking path information of the target person. With application of the automatic face tracking three-dimensional imaging system, imaging method and imaging equipment, the target person in the crowd can be locked and positioned in time, the effective path for searching the target person is planned, and the method has the advantages that the position of the target person can be recognized, displayed and positioned in time and the target person can be rapidly tracked.

Description

technical field [0001] The invention relates to the technical field of security monitoring, in particular to a three-dimensional imaging system for automatic face tracking, an imaging method and an imaging device. Background technique [0002] In large public places such as airport terminals, railway station halls, gymnasiums, shopping centers, etc., which are characterized by dense population, high mobility, and complex space environments, electronic monitoring systems are generally installed to detect various people who need to be paid attention to in time. , such as wanted persons, terrorists, persons who have committed illegal activities such as fighting and disturbing order, and persons in need of help such as some vulnerable groups, lost persons and important guests. [0003] A conventional electronic monitoring system is mainly composed of cameras, transmission cables and display screens. First, a large number of cameras are installed in public places, and then the ca...

Problems solved by technology

[0004] Although the above-mentioned supervision system has certain effects, there are many shortcomings. For example, the on-site duty personnel can only rely on the walkie-talkie to communicate with the monitoring personnel, and it is difficult for the duty personnel to effectively grasp the specific location and appearance of the target person through a short dialogue. Therefore, it is difficult to find the target person to be locked in time among the crowds in public places, which delays the response time of the on-site personnel and increases the difficulty of on-site disposal

Furthermore, even if the on-site duty personnel lock the target person, if the target person moves quickly in the crowd, it is difficult for the on-site duty personnel to follow and track accurately, so it is easy to lose the target person
