Embodiment Construction

[0026]The technical solutions of the present invention will be further described in detail below with reference to the drawings.

[0027]Such asfigure 1 As shown, this embodiment is mainly divided into three parts: LIDAR, RFID reader and label and data processing module. Lidar is used in real time to obtain human body behavior within the field of view; RFID tags are responsible for determining target IDs and auxiliary classification; data processing modules are used for model training and prediction.

[0028]The human behavior identification system deployment architecture of the present embodiment is asfigure 2 As shown: The RFID antenna is fixed to the top of the ceiling, which is equipped with RFID tags for the subject in the Lidar field of view, and is fixed to the shoulder; the data collected by RFID and LIDAR is detected by static or dynamic human behavior. Real-time identification of human behavior.

Abstract

A human body behavior identification method based on a laser radar and an RFID comprises two types of static human body behavior identification and dynamic human body behavior identification, and is structurally and mainly divided into three parts: a LiDAR, an RFID reader and label, and a data processing module. The LiDAR is used for acquiring human body behaviors in a field of view in real time; the RFID label is responsible for determining a target ID and assisting classification; the data processing module is used for model training and prediction. According to the method, privacy, safety and robustness of human body behavior identification are emphasized, and accurate behavior identification can be carried out in a complex and changeable environment.

Description

Technical field[0001]The present invention relates to the field of human behavior recognition, and more particularly to a human behavior identification method based on laser radar and RFID.Background technique[0002]Light Detection and Ranging, Lidar, is a radar system such as the position, speed of the laser beam detection target. The working principle is to transmit the laser beam to the target, and then compare the received target echoes from the target reflection with the transmitted signal, and obtain the target information, such as the target distance, a position, the height, Speed, posture, or even shapes such as parameters such as aircraft, missiles, etc., to detect, track and identify.[0003]Radio Frequency Identification, RFID is a communication technology that uses a wireless radio frequency manner to perform non-contact bidirectional communication to achieve identification purposes and exchange data, which can identify high-speed moving objects or still objects and simulta...
