Abstract

The invention discloses a high-precision portrait recognition method for security and protection monitoring, and the method comprises the steps: collecting a face image set, and carrying out the preprocessing operation, and obtaining a face processing set; performing feature extraction on the face processing set to obtain a face extraction set, wherein the face extraction set comprises contour data and feature data of the face; analyzing and calculating the face extraction set to obtain a face profile value and a face feature value, and analyzing the face profile value and the face feature value to obtain an analysis set; matching the analysis set with analysis data pre-stored in a database to obtain an analysis result; the invention further discloses a high-precision portrait recognition system for security and protection monitoring. According to all aspects disclosed by the invention, the technical problem that in the existing scheme, the acquired portrait information cannot be analyzed in real time and cannot be subjected to secondary processing verification to overcome the influence of the external environment on recognition, so that the recognition precision is poor is solved.

Description

technical field [0001] The invention relates to the technical field of portrait recognition, in particular to a high-precision portrait recognition method and system for security monitoring. Background technique [0002] The security monitoring system uses optical fiber, coaxial cable or microwave to transmit video signals in its closed loop, and constitutes an independent and complete system from camera to image display and recording; face recognition is based on human facial feature information for identification A biometric identification technology for recognition; traditional face recognition technology is mainly based on visible light image face recognition, but this method has insurmountable defects, especially when the ambient light changes, the recognition effect will drop sharply, which cannot meet actual system needs. [0003] The defects of the existing high-precision portrait recognition methods for security monitoring include: the inability to analyze the coll...
