Office space real time alarm system

Abstract

The invention relates to an office space real time alarm system. The system includes a parameter authentication device arranged at the entrance of an office space, used for measuring current air humidity and sending signals indicative of excessively high humidity when the current air humidity surpasses a limit and sending signals indicative of normal humidity when the current air humidity does notsurpass the limit; a dehumidification device arranged at the entrance of the office space, connected with the parameter authentication device and used for executing dehumidification operation corresponding to the current air humidity when receiving the signals indicative of excessively high humidity; a field alarm device used for receiving an edge sharpened image, performing face detection on theedge sharpened image so as to acquire work numbers of office staff entering the office space based on detected face features and performing corresponding sound light alarm operation when work numberacquisition fails. According to the invention, a condition of staff identity identification failure is avoided.

Description

technical field [0001] The invention relates to the field of feature analysis, in particular to a real-time alarm system for office spaces. Background technique [0002] Face recognition specifically refers to computer technology that uses analysis and comparison of facial visual feature information for identity identification. Face recognition in a broad sense actually includes a series of related technologies for building a face recognition system, including face image acquisition, face positioning, face recognition preprocessing, identity confirmation, and identity search; A technology or system for face recognition or identity search.

Problems solved by technology

[0003] In order to solve the technical problem of insufficient identification accuracy of office personnel, the present invention provides a real-time alarm system for office, which performs a dehumidification operation corresponding to the current air humidity when receiving a signal of excessive humidity, so as to ensure the safety of on-site electronic equipment. In normal operation, at the same time, various targeted image processing devices are introduced to improve the clarity of the processed image; in addition, the number of noise types with the number of preset numbers in front of the serial number is used as the maximum number of noises, based on the maximum noise The number determines the number of layers for signal segmentation, the number of various noise types in the high-definition image is used as the reference noise number, and the percentage value for shrinking the wavelet coefficients is determined based on the reference noise number, thereby realizing the target image based on image content image denoising
