Three-dimensional face recognition method for entry and exit administration

Abstract

The invention relates to the technical field of face recognition, in particular to a three-dimensional face recognition method for entry and exit administration. The method includes: by an infrared receiver, receiving infrared rays emitted by a face, and starting image acquisition after receiving the infrared rays emitted by the face; image acquisition, to be more specific, acquiring the dynamic contour of a face image and images of the eyes, the nose, the mouth, the eyebrows and the forehead, and transmitting the dynamic contour and the images to an image preprocessing chip and a memory chip; image preprocessing, to be more specific, filtering and sharpening the face image; image feature extracting, to be more specific, performing blocked feature extraction on the image information, and building a histogram; using a decision tree classifier to compare the extracted blocked features with a face feature library. The three-dimensional face recognition method for entry and exit administration has the advantages that criminal suspects can be positioned fast, reliability is increased, and intelligent recognition is accurate; a three-dimensional face recognition machine is started by the infrared receiver, a system stays in a standby state automatically when the system is not used, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to a three-dimensional face recognition method for entry-exit management. [0002] Background technique [0003] At present, 3D face recognition technology is mainly used in the field of attendance and access. When opening a provident fund account, the original ID card and its copy are generally required, which is cumbersome. A 3D face recognition method for entry-exit management is proposed. [0004] Contents of the invention [0005] The purpose of the present invention is to overcome the above problems and provide a three-dimensional face recognition method that is more accurate in recognition, helps to quickly locate criminal suspects, and is in a standby state when the three-dimensional face recognition instrument is not in use. [0006] In order to achieve the above object, the technical solution adopted in the present invention is: a three-dimensional face recogn...
