Abstract

The invention provides a personnel identification method and system combining video identification and UWB (ultra-wideband) positioning technologies. The method comprise the steps of: A, in the simulation filed of a same supervision area, obtaining geographical positions of mobile positioning objects and the first quantity of the geographical positions according to video identification positioning, and obtaining positioning coordinates of positioning terminals and the second quantity of the positioning coordinates according to wireless positioning; B, comparing the first quantity and the second quantity at a same time, prompting abnormity and entering C if the first quantity is not equal to the second quantity, and prompting normality if the first quantity is equal to the second quantity; and C, obtaining abnormal geographical positions according to the matching between the positioning coordinates and the geographical positions. The method and system can efficiently monitor specific objects and specific occasions such as a campus, analyze and determine in real time position monitoring and video image monitoring information, and timely provide alarm response service, thereby enhancing campus safety service.

Description

technical field

[0001] The present invention relates to the technical field of the Internet of Things, in particular to a person identification method and system that integrates video identification and UWB positioning technology. Background technique

[0002] With the needs of social mobility and public safety, more and more functions are involved in the monitoring system. It is basically a traditional surveillance camera plus a surveillance display, and the surveillance is realized manually. It is basically impossible to realize intelligent identification and dynamic viewing. The differences and effects of manual monitoring are time-consuming and laborious, and the efficiency is very low.

[0003] The current emerging Internet of Things technology connects information sensing equipment with the Internet, local area network, etc., and exchanges and communicates information such as the environment, time, and status of the target terminal identification device to realize the...

Embodiment Construction

[0056] The present invention will be described in detail below in terms of specific embodiments in conjunction with the accompanying drawings. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It is to be noted that other embodiments may be utilized or structural and functional modifications may be made to the embodiments set forth herein without departing from the scope and spirit of the invention.

[0057] The receiving device in this embodiment will obtain the first distance from the UWB pulse signal sent by the positioning terminal. If it is two-dimensional positioning, at least three receiving devices are required; if it is three-dimensional positioning, at least four receiving devices are required. The positioning server obtains the ranging results of each receiving device according to the first distance sent by these receiving devices. It is equivalent to measuring...
