Description
Technical field
The present invention relates to monitoring technologies, and in particular to a kind of personnel monitoring's method based on image detection and wireless probe
And system.
Background technology
In important institutional settings and critical infrastructures place, all there is more demanding special of some safe classes
Region.These regions strictly forbid irrelevant personnel to access, and forbid donor according to access level limitation or access time limitation
Member accesses.The scene requirement region of access time limitation, which limits personnel in some special time period and accesses, to be entered, such as
The road and bridge of maintenance, because of closed scenic spot of weather reason etc..Only certain personnel are opened in the scene requirement region of access level limitation
Put, for example, the safe care registry of institutional settings, communication common carrier computer room etc..In addition to this, there is also simultaneously require access time by
The special area that limit and access level are limited, for example, the production district etc. of the substation of electric company, chemical plant.
Existing monitoring scheme at present, usually using dependence video human face identification technology, RFID technique.For example, patent " one
Kind recognition of face tracking and system " (CN103824045A) describes a kind of personnel tracking using face recognition technology
