FIELD: electric engineering. ^ SUBSTANCE: invention is related to technology of video surveillance arrangement, namely to systems and methods of automatic separation and tracking of human being face for biometric identification of a person. In method they detect presence of a human being in zone of surveillance with the help of two and more distanced video cameras with their previously known location; head position is identified in zone of surveillance, using a priori data on geometric dimensions; face area is separated together with position of elements, such as eyebrows, eyes, nose, mouth, on detected face; simultaneous tracking over three types of objects (point, area, graph) is carried out on face; based on a priori and detected data 3D face model is reconstructed; in case of sufficient completeness and integrity of informative criteria of produced 3D face model, angles are calculated, which define orientation of head in space; in case detected angle is sufficiently representative and differs from angles at previous frames, face is recognised based on most representative frames of image. System realizes specified method. ^ EFFECT: higher accuracy and speed of human face detection and tracking, and also expansion of application field. ^ 11 cl, 9 dwg |
