    摘要: The present application discloses a method and device of detecting fatigue driving, comprising: analyzing an eye image in the driver's eye image area with a rectangular feature template to obtain the upper eyelid line; determining the eye closure state according to the curvature or curvature feature value of the upper eyelid line; and collecting statistics on the eye closure state and thereby determining whether the driver is in a fatigue state. The present application determines whether the eyes are opened or closed according to the shape of the upper eyelid, which is more accurate because the upper eyelid line has characteristics of higher relative contrast, anti-interference capacity, and adaptability to the changes in the facial expression.

    摘要: The present invention utilizes a high-speed serial data transceiver to generate two high-speed electric pulse signals. After passing through a gain network, the signals are used for driving an electro-optic phase modulator (PM) so as to realize phase modulation of photon signals. The present invention may directly use a high-speed digital signal to realize a four-phase modulation function needed by the BB84 quantum key distribution protocol without using a digital to analog converter or an analog switch. This can prevent modulation rate from being restricted by links including digital-to-analogue conversion, switching of the analogue and the like. A dual-electrode electro-optic phase modulator scheme can also effectively reduce requirements for amplitude of a modulation driving signal, thus facilitating realization of high-speed phase modulation, which meets requirements of quantum key distribution.
