FIG. 1 is a view schematically showing a configuration of a rearview mirror 100 capable of measuring and displaying bio-signals in a vehicle according to an embodiment of the present invention. 1, the rearview mirror 100 includes a sensor unit 110, a controller 130, and a display unit 150. The sensor unit 110, the controller 130, and the display unit 150 can be used to measure and display a living body signal in a vehicle according to an embodiment of the present invention. And may further include an alarm unit 170. [0035]

The sensor unit 110 can sense the driver's biological signal without restriction. That is, in sensing the driver's biomedical signal, the driver can directly sense the driver's body without touching it directly. The specific configuration of the sensor unit 110 will be described later in detail with reference to FIG.

The control unit 130 can detect the biometric data by analyzing the biometric signal detected by the sensor unit 110. The specific configuration of the controller 130 will be described later in detail with reference to FIG. 2 to FIG.

The display unit 150 can display the biometric data detected by the control unit 130 and thus the driver can easily confirm the biometric data in real time through the display unit 150. [ The specific configuration of the display unit will be described later in detail with reference to FIG.

The alarm unit 170 can output a warning signal, and the specific configuration of the alarm unit 170 will be described later in detail with reference to FIG.

2 is a view illustrating a sensor unit 110 of a rearview mirror 100 capable of measuring and displaying bio-signals in a vehicle according to an embodiment of the present invention. 2, the sensor unit 110 of the rearview mirror 100 capable of measuring and displaying bio-signals in a vehicle according to an embodiment of the present invention includes a camera 111 for recognizing the face of a driver .

That is, by recognizing the face of the driver through the camera 111 installed on the front face of the rearview mirror 100, it is possible to sense the driver's biomedical signal without restraint. Here, the sensor unit 110 can detect a pulse from a facial image recognized through the camera 111. [

More specifically, a facial image acquired through the camera 111 can be analyzed and a pulse can be sensed using an image processing technique. At this time, according to the embodiment, for each frame acquired from the facial image, It is possible to detect the pulse.

At this time, the control unit 130 can detect the ratio of the sympathetic / parasympathetic nerve by analyzing the frequency of the pulse signal sensed by the sensor unit 110. [ That is, through the frequency analysis of the pulse signal, the ratio of sympathetic and parasympathetic nervous system states that indicate the driver's drowsiness state and the autonomic nervous system state associated with the Wellness index can be detected.

More specifically, according to an embodiment, a pulse period is determined from a sensed pulse signal, a pulse rate variability (PRV) is detected, and the sympathetic and parasympathetic nerves Can be detected. Further, in some embodiments, a fast fourier transform (FFT) may be used for frequency analysis of the pulse variation (PRV).

Thus, the ratio of detected sympathetic nerves and parasympathetic nerves can be represented by the LF / HF ratio, which is an index indicating the activity ratio of the sympathetic nervous system and the parasympathetic nervous system. Here, LF (low frequency component) HF (high frequency component) can have information on the parasympathetic nervous system, in particular, the activity of vagus nerves and respiratory activity.

Meanwhile, according to the embodiment, the controller 130 may sense a pulse from a facial image recognized through the camera 111 of the sensor unit 110. [ That is, in this case, the camera 111 of the sensor unit 110 recognizes the face of the driver unrestrainedly, and the control unit 130 performs image processing as described above from the facial image recognized by the sensor unit 110 Technique, and the ratio of the sympathetic / parasympathetic nerve can be detected by analyzing the frequency of the finally detected pulse signal.

The display unit 150 includes a display unit 150 and a display unit 150. The display unit 150 may be connected to the HUD 200 and may include at least one of a pulse rate and a sympathetic / Data may be displayed.

Here, the HUD 200 is a display device for displaying various information on the windshield of the driver. Although not shown for the sake of convenience, the HUD 200 can display vehicle speed information and various kinds of warning of a vehicle, It can also display route guidance. By displaying the biometric data in cooperation with the HUD 200, it is possible to keep the driver's field of view forward, thereby assisting safe driving.
