Man-machine interaction method based on millimeter wave radar

Abstract

The invention discloses a man-machine interaction method based on a millimeter wave radar. The method comprises the following steps of: (1) performing initialization through a main control module, performing parameter setting on a millimeter wave radar module, a data processing module and an intelligent identification module, and sending a working instruction to the millimeter wave radar module; (2) transmitting linear frequency modulation continuous waves to a target scene by the millimeter wave radar module, collecting echo signals reflected by a target object to a script module through a receiving antenna, performing frequency mixing with transmitted signals to obtain intermediate frequency signals, and transmitting the intermediate frequency signals to the data processing module; (3) executing a resolving algorithm by the data processing module to obtain feature data, and transmitting the feature data to the intelligent identification module; (4) analyzing corresponding actions andinstructions by the intelligent identification module according to the feature data, and feeding back the corresponding actions and instructions to the main control module; and (5) issuing a controlinstruction by the main control module according to the feedback, and driving equipment to complete corresponding control actions. According to the man-machine interaction method disclosed by the invention, smart home equipment is expanded to perform interaction, so that the smart home equipment can feed back action posture instructions, and specific control operations can be realized according tomodel comparison.

Description

technical field [0001] The invention belongs to the field of intelligent identification and human-computer interaction, and in particular relates to a human-computer interaction method based on millimeter wave radar. Background technique [0002] Human-computer interaction refers to the technology of realizing the dialogue between man and machine in an effective way through computer input and output devices. From the perspective of the development track and trend of human-computer interaction, it can be divided into the following development stages: (1) The interaction stage based on the keyboard and command language, that is, the command language is used to drive the machine operation; (2) The interaction stage based on the mouse and graphical user interface In the interaction stage, the problems of precise positioning and fast switching are solved; (3) In the stage of touch screen interaction based on multi-touch technology, with the development of mobile Internet, multi-t...
