Embodiment

[0035] According to a face recognition-based mobile crowd video monitoring method in the embodiment, the face recognition system is divided into two parts: the front-end monitoring equipment and the control platform according to the function and complexity: the front-end monitoring equipment performs high-resolution digital video image preprocessing and The background face recognition control platform enables the front end to process the video image at the place where the image is generated before transmission, screen out valuable face images, filter out more than 99.9% of useless data, and control the PTZ and optical lens, Capture high-definition face images, and only send valuable images to a remote background server through wired or wireless channels for further processing and recognition of face images.

Abstract

The invention provides a migrant crowd video surveillance method based on face recognition. Through a face recognition surveillance camera, a real-time digital video is collected, an original image inthe real-time digital video is preprocessed to screen face images which can be used for comparison and recognition, and the obtained face images which can be used for comparison and recognition are transmitted to a control platform through a telecommunication network; and a control platform is connected to a face server to recognize the face images. By use of the method, in the digital video image with an ultrahigh resolution, the face image can be found in time, a camera optical lens and a head can be controlled to track and amplify the valuable face to be subjected to optimal state capture,the valuable face image is provided for a remote background face recognition server or portable equipment, a data size which needs to be transmitted is greatly lowered, and the face recognition accuracy and speed of a surveillance system is improved.

Description

technical field [0001] The invention relates to a face recognition-based video surveillance method for floating crowds. Background technique [0002] Existing face recognition servers can compare two face images, usually a face image captured in real time, and compare it with a standard ID photo in the database to find out who the person is now, such as an airplane At airports and high-speed rail stations, passengers are required to take a photo of the security camera for a long enough time, and then compare it with the submitted ID card to confirm that it is the same person. [0003] However, in more application scenarios, such as surveillance systems in public places and law enforcement cameras, it is impossible to require everyone passing by to stand in front of the camera to take a standard photo, and then wait for dozens of seconds for the server to identify. On the monitoring system and law enforcement cameras, the images obtained by the cameras are intricate and chan...
