Face recognition and face automatic library building algorithm for security check gates based on multi-camera fusion

Abstract

In order to solve the problem on how to realize fast security check at security check gates, the invention presents a face recognition and face automatic library building algorithm for security checkgates based on multi-camera fusion. The algorithm of the invention does not require checked persons to be face-identified actively and cooperatively, and checked persons can just walk according to thenormal route. The algorithm is a non-cooperative face recognition algorithm. Multiple cameras are installed on a security check gate along the direction in which people enters the security check gate, and the cameras simultaneously collect videos to carry out face detection. Detected faces are screened by a face quality evaluation module after face tracking. The faces of the same person are selected from the screened faces through a corresponding upper body matching algorithm. The oversized faces are deleted through pose estimation. After alignment and calibration, the remaining faces are input to a deep convolution neural network for feature extraction. Based on the extracted features, face matching and automatic library building are carried out through a multi-camera face comparison algorithm. By using the face recognition and face automatic library building algorithm for security check gates based on multi-camera fusion, the speed of security check is greatly increased, and congestion and other security risks caused by security check are reduced.

Description

technical field [0001] The invention belongs to the field of security and security inspection, and relates to pattern recognition, graphic image processing, machine learning, etc., using multiple cameras to collect faces, and merging these faces through face pose estimation and face recognition technology based on deep learning, Then automatically build a multi-camera face recognition library. Background technique [0002] The world seems to be peaceful, but it is not safe. Terrorism and extremism are quietly infiltrating people's lives, so security precautions are still a very important topic. To a certain extent, security inspection can detect dangerous goods in time to ensure the safety of people's lives and property. Security inspection equipment has been deployed in various public places such as airports, subways, and important venues. The security gate is a kind of equipment for detecting the human body. The domestic human body security check mainly adopts walk-throug...
