Apparatus and Method for notifying correction of posture}

The present invention relates to a vehicle, and more particularly, to an apparatus and method for determining a driver's posture and providing a notification for posture correction.

As various media and computer devices are developed, the period of sitting on a chair is increasing. Accordingly, there is a trend of increasing the number of diseases such as discs, fifty shoulders, etc. due to poor posture during chair seating, and in recent years, interest in the health of the neck, spine, arms, and pelvis causing these diseases is increasing.

As such, there is an urgent need for a posture correction system to maintain proper posture in order to prevent diseases caused by an incorrect sitting posture for modern people who are sitting for a long time. Such a posture correction system has various forms and functions. It is proposed.

In this regard, Korean Utility Model Publication No. 0136872 discloses a driver's posture failure warning device using a piezoelectric sensor. According to this, the driver's posture failure warning device distributes and installs a plurality of piezoelectric sensors at predetermined positions on a vehicle seat back surface. By connecting the analysis device for analyzing the body pressure distribution of the human body to the sensor, by connecting the control unit connected to the buzzer to the analysis device has a structure that informs the driver through the buzzer when the driver's tax is bad during driving.

However, according to such a configuration, the piezoelectric sensor can only detect whether there is a bad posture, and information on how the posture is incorrect and how to correct the posture has an unknown disadvantage.

In addition, since the body pressure distribution analysis of the human body is used, there is a disadvantage that it is not suitable for the correction of the neck posture such as a turtle neck.

On the other hand, Korean Patent Laid-Open No. 10-2016-0127872 discloses a treatment device for measuring and correcting turtle neck, but according to this, there is a disadvantage in that it is inconvenient to apply it when driving an EMG sensor on the neck. In addition, there is a disadvantage in that a tilt detection sensor or the like for additionally detecting the neck is additionally required.

Hereinafter, a posture correction notification device and method according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a conceptual diagram of a posture correction notification device according to an embodiment of the present invention. Referring to FIG. 1, the driver 110 is seated on the seat 120 of the driver's seat installed in the vehicle 100. The steering wheel 140 is installed in front of the driver 110. At the upper end of the seat 120, a head rest 130 on which the head of the driver 110 is seated is configured. An image photographing device for monitoring a posture of the driver 110 is installed at the upper end portion 150 of the inner wall of the driver's seat of the vehicle 100.

FIG. 2 is a conceptual diagram of detecting a corrected posture in the posture correcting notification device illustrated in FIG. 1. Referring to FIG. 2, the head of the driver 110 is placed on the front of the head rest 130. In this case, the posture is a normal state, and posture correction is not necessary.

3 is a conceptual view of detecting a turtle neck posture in the posture correcting notification device illustrated in FIG. 1. Referring to FIG. 3, the head of the driver 110 is separated from the front of the head rest 130. In this case, the driver 110 is an abnormally suspected abnormal posture such as a turtle neck. Therefore, calibration is required at this time. A pressure sensor is installed on the front surface of the head rest 130 shown in FIGS. 2 and 3.

These pressure sensors can be classified as follows.

division judgment action Pressure A Correct posture (initial user input) none Pressure B Tortoise Detection signal generation

The corrected posture refers to the initial posture desired by the user. To this end, the driver 110 initially photographs a desired corrected posture using an imager. Since this is a still picture and becomes a reference for comparison with a later monitored picture, it is reference calibration image information (ie, an initial picture).

4 is a circuit block diagram of the posture correction notification device shown in FIG. Referring to FIG. 4, the posture correcting notification device may include an imager 420 for generating state image information of a driver, a pressure sensor 430 for generating a detection signal according to a movement of a driver's head, and whether or not the detection signal is received. The controller 410 may be configured to compare the state image information with preset reference calibration image information, and generate posture correction alarm information according to a comparison result, and output means for outputting posture correction alarm information.

The imager 420 may be a charge-coupled device (CCD) camera, a complementary metal-oxide semiconductor (CMOS) camera, or the like. The imager 420 is installed on the driver's left wall (or roof frame) side of the driver's seat to monitor the driver's posture. In particular, when an abnormal posture is detected from the pressure sensor 430, the image photographing apparatus 420 generates state image information (ie, a still picture) showing the current posture of the driver. Of course, when the DSW (Driver State Warning) system is installed in the vehicle without using the separate imager 420, it is also possible to use an indoor camera installed in the cluster. In this case, the front of the driver is mainly monitored to determine the driver's posture.

The pressure sensor 430 generates a detection signal according to the driver's head movement. In other words, in the case of FIG. 2, the pressure sensor 430 does not generate a detection signal because the driver is in a corrected posture state. 3, the pressure sensor 430 generates a detection signal since the driver is in an abnormal posture state.

The controller 410 compares the state image information with preset reference calibration image information according to whether the detection signal is received, generates the posture correction alarm information according to the comparison result, and displays the display 440 and / or the speaker ( 450). In other words, the controller 410 takes the corrected posture desired by the driver in advance and corrects the principal's posture with the imager 420 and stores the reference corrected image information. Thereafter, the degree of similarity is determined by comparing the stored reference calibration image information and the currently captured state image information according to the detection signal of the pressure sensor 430.

Of course, an image processing algorithm is used for this. In other words, only the driver is recognized by focusing on the still image, and only the driver's outline is deleted through spatial filtering, and other parts are deleted to compare the screens of each other to determine similarity. That is, the image processing algorithm has a process of manipulating and analyzing image data to derive useful information using image processing software, programs, and the like. It represents image compression, image reconstruction, image enhancement, image correction, preprocessing, quantification, spatial filtering, and other image type recognition techniques. Such image processing techniques are well known in the field of inspecting defects in manufacturing processes. Accordingly, further description will omit a clear understanding of the invention.

Accordingly, the controller 410 may include a microprocessor, a digital signal processor (DSP), a memory, a microcomputer, and the like. The memory can be a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (e.g. SD or XD memory), RAM (Random Access) Memory, RAM), SRAM (Static Random Access Memory), ROM (ReadOnly Memory, ROM), EEPROM (Electrically Erasable Programmable ReadOnly Memory), PROM (Programmable ReadOnly Memory), magnetic memory, magnetic disk, optical disk It may include a storage medium.

4, the controller 410 also generates a posture correction alarm information if it is determined that the result of the comparison between the state image information and the reference calibration image information is out of the same preset range through a comparison algorithm. . The comparison algorithm may be written in a programming language such as C or C ++.

The output means for outputting the posture correction alarm information of the controller 410 may include a display 440, a speaker 450, and the like. The display 440 may be a liquid crystal display (LCD), a light emitting diode (LED) display, an organic LED (OLED) display, a touch screen, a flexible display, a head up display (HUD), or the like.

Therefore, the posture correcting alarm information may be generated by a combination of graphic, voice, and text.

5 is a flowchart illustrating a posture correction notification process according to an embodiment of the present invention. Referring to FIG. 5, in the standby mode state, the controller 410 checks whether a detection signal is input from the pressure sensor 430 (steps S510 and S520).

In step S520, if the detection signal (pressure A) is input, the imager 420 generates the driver's state image information (image B), and compares the state image information (image B) with the reference calibration image information (image A). (Step S530).

As a result of the comparison, it is checked whether the state image information (image B) and the reference corrected image information (image A) are within the same range (or similar range) (step S540). In this case, as previously described, a given error range is given.

If the state image information (image B) and the reference correction image information (image A) are not in the same range (or similar range), the posture correction alarm information for posture correction is generated and output to the output means (step S550). That is, it outputs a GUI (Graphic User Interface) and a voice announcement.

In addition, the steps of a method or algorithm described in connection with the embodiments disclosed herein may be embodied in a program instruction form that can be executed by various computer means and recorded in a computer-readable medium. The computer readable medium may include program (instruction) code, data file, data structure, etc. alone or in combination.
