Embodiment Construction

[0017] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] Such as figure 1 As shown, a method for collecting spatial gesture password input based on millimeter waves provided by the present invention comprises the following steps:

[0019] Step (1), host computer initialization: the host computer is initialized, and the connection situation with the password collection device is checked;

[0020] Step (2), control communication: used to send self-inspection instructions and set the password sequence length, let the password collector perform self-inspection, and return the self-inspection data to the host computer, send the start-up command to the millimeter-wave radar device, and Return the power-on status data to the host computer;

[0021] Step (3), start the laser auxiliary module: ...

Abstract

The invention provides a space gesture password input acquisition method based on millimeter waves. The space gesture password input acquisition method comprises the following steps: (1) initializingan upper computer; (2) controlling communication; (3) starting a laser auxiliary module; (4) inputting a space gesture password; (5) the millimeter-wave radar receives the spatial position information; (6) processing the password information and returning the password information to the upper computer; and (7), processing the password by the upper computer. By means of the password input method, the problems that in the prior art, when passwords are input on a screen, traces are prone to being left, secrecy safety is low, and the risk that viruses are spread among people is caused are solved.

Description

technical field [0001] The invention relates to the technical field of millimeter-wave radar distance measurement, in particular to a millimeter-wave-based space gesture password input collection method. Background technique [0002] Millimeter-wave ranging is a group of continuous millimeter-wave beams emitted by the radar transmitter, which will return when it encounters an object, and the distance is measured by calculating the time difference between the transmitted beam and the reflected beam. Gesture password, that is, the sequence in which the fingers move to fixed points in turn is used as the password key. Due to the popularity of Internet mobile devices, gesture passwords are used on many mobile devices. Gesture passwords are easy to remember, difficult to crack and have certain security. Currently, they are widely used in mobile device power-on / off verification. However, entering passwords on the screen is easy to leave traces, and the security of confidentiality...
