Abstract

The invention discloses a high-precision portrait recognition method for security monitoring. By collecting a face image set and performing a preprocessing operation, a face processing set is obtained; by performing feature extraction on the face processing set, a face extraction set is obtained. The face extraction set contains the contour data and feature data of the face; through the analysis and calculation of the face extraction set, the face contour value and face characteristic value are obtained, and the analysis set is obtained by analyzing the face contour value and face characteristic value; the analysis set is combined with The analysis data pre-stored in the database are matched to obtain the analysis results; the invention also discloses a high-precision portrait recognition system for security monitoring; various aspects disclosed in the invention solve the problem that the existing solutions cannot perform real-time analysis on the collected portrait information And carry out secondary processing verification to overcome the influence of the external environment on the recognition, resulting in the technical problem of poor recognition accuracy.

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...
