Embodiment Construction
[0024] The solution of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0025] The present invention adopts the image detection method based on OpenCV and the wireless probe scanning method based on mobile phone wifi to realize the monitoring and tracking of the personnel position in the limited area without additional wearable devices. The image detection method uses a general-purpose video camera acquisition device, uses OpenCV-based image intrusion detection, object movement detection and other mature technologies to extract key image information and abnormal information, and discover personnel access behaviors in the monitored area. The wireless probe scanning method adopts the Probe frame active detection technology based on the IEEE802.11 protocol and the RSSI positioning technology to judge the identity information and location of the intruder, and combined with the results obtained by the ima...

The invention discloses a personnel monitoring method and system based on image detection and a wireless probe. The method comprises the following steps: firstly extracting key image information and abnormal information by utilizing a video camera acquisition device and using technologies such as image intrusion detection and object movement detection, and finding a personnel access behavior in amonitored area; then judging identity information and location of an invasion person by utilizing a wireless probe scanning method and adopting a Probe frame active detection technology and an RSSI positioning technology; and finally judging whether an unauthorized person invades a limited area by combining a result obtained by an image detection method. The method disclosed by the invention improves field monitoring recognition precision and efficiency and reduces field operation complexity and equipment cost.
Description
technical field [0001] The present invention relates to monitoring technology, in particular to a method and system for personnel monitoring based on image detection and wireless probes. Background technique [0002] In important institutions and key infrastructure sites, there are some special areas with higher security level requirements. Access to these areas is strictly prohibited by unrelated personnel, and access by authorized personnel is prohibited based on access level restrictions or access time restrictions. The scenario of access time restriction requires the area to restrict access to personnel within a certain period of time, such as roads and bridges under maintenance, scenic spots closed due to weather, and so on. The scenario of access level restriction requires that the area is only open to certain personnel, such as the confidential room of the government unit, the computer room of the communication company, and so on. In addition, there are special area...
