Image processing system capable of reminding driver to drive carefully and preventing doze

An image processing system that alerts the driver to driving and anti-sleepiness

This creation is about one, especially an image processing system that alerts the driver to driving and anti-snoring.

Traditional car drivers, when driving on the road for a long time, will have severe fatigue, especially during nighttime driving. At this time, it is also a dangerous period of traffic on the road. Many traffic accidents are often caused by the drivers negligence. I fell asleep unconsciously, and an accident occurred. In order to prevent the above-mentioned driver from falling asleep, some items that prevent the driver from sleeping are developed, for example, a car audio-visual device, a cushion massage device or an electric shock device, the functions of which are used to prompt the driver to concentrate on driving. . Under the active development of the electronics industry, the miniaturization of electronic products is no longer a technical problem. Instead, it is to meet the technical needs, that is, the human-machine interface factors limit the degree of volume miniaturization, such as the above Even so, the oversized device often causes the operator to bear the cost and make it unacceptable to consumers.

An anti-sleep device developed in the prior art, such as the Republic of China Patent Application No.: 097204139, proposes a device, in particular, an anti-snoring device body, a connecting device is disposed on the body of the anti-snoring device, and a gravity is disposed inside a tilting sensor for sensing a horizontal tilt of the anti-snaking device body; a vibration device disposed on the anti-snaking device body, when the gravity tilt sensor detects a tilt angle exceeding a certain degree, is turned on The vibration device increases in vibration level as the tilt angle increases; a timer detects when the level detecting device remains stationary for a certain period of time for more than a certain period of time, or tilts for a certain period of time (nodding) When the number of times reaches a certain number, a warning is activated; and a wireless transmission earphone body (such as a Bluetooth), on the wireless transmission earphone body (such as a Bluetooth), a fixing device is disposed with respect to the connecting device, so that the anti-sleeping device body Can be connected with the wireless transmission headphone body (such as Bluetooth), when it is fixed on the driving driver, it will vibrate Shows, at the same time can have a voice warning may further prompt the driver to achieve the purpose.

In addition, the Republic of China Patent No. M322041 proposes a sleep alert device, which is disposed at a suitable position near the driver's seat of the vehicle, and is provided with an oxygen deficiency sensing device. The oxygen deficiency sensing device includes: an inductor, and an output terminal is connected to a signal conversion circuit. The processor is connected to a control circuit, and the output end of the control circuit is connected with a voice alarm and a warning light; the power switch has an output connected to the control circuit, and the input end is connected to the vehicle. Power system; use the car to start the power system to start the engine, drive to the door for a certain period of time, lock the door, and turn on the power switch. The sensor detects that the air inside the car is in an oxygen-deficient environment, activates the voice alarm and warning light, reminds The driver turns on the air conditioning system to circulate outside, or open the window to achieve the ventilation demand, not only to maintain the health of the occupants, but also to improve the safety of driving, to avoid the occurrence of traffic accidents caused by fatigue and lethargy caused by lack of oxygen. In addition, the Republic of China Patent Publication No. 595790 proposes a microcomputer reminder device which is suitable for sensing the physiological phenomenon or state of the human body, and can avoid or prevent dozing during driving, meeting and reading, mainly including: a sensing unit sense To measure the physiological phenomenon of a user, a warning unit uses a physical or chemical output to effect the user. A processing unit is electrically connected to the sensing unit and electrically connected to the warning unit. It is characterized by being able to perceive the physiological phenomenon or state of the human body, and to provide timely warning notice when it is fatigued.

All of the above designs have inconvenience in installation, high cost, and no benefit, so they are not acceptable to consumers.

Therefore, the purpose of this creation is to propose an image processing system that can remind the driver to pay attention to driving and anti-sleeping. The system uses image detection to detect the blinking time of the human eye, and it is not necessary to connect the driver's body parts with the mechanical parts. And the driver can work as soon as he gets on the driver's seat.

In order to achieve the above purpose, an image processing system for alerting the driver to driving and anti-sleeping is proposed in the present invention, comprising: a camera lens is located in front of the driver's seat of the vehicle, and the camera lens can be taken when the driver is in the driving state. Entering the driver's face image; an image processor is connected to the camera lens to process the image from the camera lens; a speaker is connected to the image processor, receives the image processor signal, and generates a corresponding sound And a speaker is connected to the image processor and receives an indication from the image processor to emit a different sound to prompt the driver to pay attention to the state of the vehicle.

The image processing flow is: inputting the vehicle speed to the image processor by the speedometer originally existing in the vehicle; when detecting that the vehicle is traveling (the vehicle speed is greater than 0), the detection function is started; in this step, the sleep can be directly started. The detection function is not determined by the speed of the car. The camera lens continuously ingests the image of the driver and inputs the image into the image processor; the image processor uses software technology to find the driver's face and detects the position of both eyes in the face; The driver's eyes are in an open or closed state; when the closing time exceeds a set value, the horn sounds to alert the driver to draw the spirit to concentrate on driving; and when the driver's face is detected When the normal position and the blinking of the eyes are normal, the warning function is automatically stopped. When the vehicle is in a traveling state and the driver's eye position cannot be detected or the detected eye position is not in the normal position, the warning function is activated to alert the driver.

The creation may further include a display connected to the camera lens for displaying an image taken by the camera lens, and the driver corrects the position of the camera lens according to the image to correct the orientation of the camera lens.

The features of the present invention and its advantages can be further understood from the description below, and please refer to the attached drawings when reading.

In view of the structural composition of the case, and the functions and advantages that can be produced, together with the drawings, a preferred embodiment of the present case is described in detail below.

Please refer to Figure 1 and Figure 2, which shows the image processing system of this creation that reminds the driver to pay attention to driving and anti-snoring. The system consists of the following components:

A camera lens 10 is positioned in front of the driver's seat of the vehicle 1, and the camera lens 10 can take in the face image of the driver 15 when the driver 15 is in the driving state. Preferably, the camera lens 10 is a wide-angle lens, and the camera lens 10 is positioned on a mount (not known in the prior art, not shown) to adjust its orientation to make different drivers 15 can adjust an acceptable position according to its position. The position of the camera lens 10 shown in the figure is only for the purpose of illustration of the present invention and is not intended to limit the scope of the present creation.

An image processor 20 is connected to the image pickup lens to process images from the image pickup lens. The processing method is described below:

Please refer to FIG. 3, which illustrates the processing flow of the present creation. The vehicle speed is input to the image processor 20 by the vehicle speed meter originally existing in the vehicle (step 101). When the vehicle is detected to be traveling (the vehicle speed is greater than 0), The sleep detection function is started (step 102). In this step, the sleep detection function can be directly activated, and is determined not by the vehicle speed. First, the camera lens 10 continuously takes in the image of the driver and inputs the image into the image processor (step 103); the image processor uses software technology to find the driver's face and detects the face. Position of both eyes (step 104); then determining whether the driver's eyes are in an open or closed state; applying the number of pictures or other means to calculate the time of eye sequence closure (step 105), if the camera The imaging frequency is 60 pictures per second. If there are 30 consecutive eyes in the picture, the eyes are closed for 0.5 seconds. The rest of the situation can be pushed in one way. The details are not described; when closed When the time exceeds a set value, the horn sounds to alert the driver to draw the spirit to concentrate on driving (step 106); when the driver's face is detected in the normal position and the blinking of the eyes is normal, the warning is automatically stopped. Function (step 109).

When the vehicle is in a traveling state and the driver's eye position cannot be detected or the detected eye position is not in the normal position (step 107), it is possible that the driver is asleep or is not related to driving. Therefore, the image processor in this case also activates an alert function to alert the driver (step 108). When it is detected that the driver's face is in the normal position and the blinking of the eyes is normal, the alert function is automatically stopped (step 109).

The so-called eye position is not in the normal position, that is, the driver's head may turn to one side, or the head may sag (may be asleep), which may cause dangerous driving, so the mechanism of this creation must be activated to prevent accidents.

A speaker 30 is coupled to the image processor to receive signals from the image processor and to generate a corresponding sound.

A horn 40 is coupled to the image processor and receives an indication from the image processor to emit a different sound to alert the driver to the status of the vehicle.

According to the above logic, when the car retreats, a warning sound is also emitted. There are two ways in this creation, that is, when the vehicle is retreating, the function of the creation is automatically closed, and the other is when the vehicle is retreating. A warning sound is also issued to alert the customer.

The present invention may further include a display 50 connected to the camera lens 10 for displaying an image taken by the camera lens 10, and the driver 15 may correct the position of the camera lens 10 according to the image. The orientation of the imaging lens 10 is corrected.

In this case, the "re-cue" status can be further set. If the image processor in this case continuously detects that the driver has a state of continuous long-term closed eyes, a large and surprising sound or voice prompt is issued to inform the driver to park the car in a safe place and take a break. On the road.

This creation also provides a way to boost the spirit of the driver, including the following:

To make the music sound from the speaker to boost the driver's spirit, and not easy to doze off; or to issue a warning warning, such as telling the driver to drive the car to the side of the road or to a safe parking lot and take a break to avoid A traffic accident has occurred.

The creation can also be connected to other mental reminder devices 60, such as a fragrance dispenser, such that when the driver is detected to be dozing, a fragrant taste can be emitted to keep the driver happy.

The creation also includes a switch 70 that is used to initiate the functionality of the author. Such as power start or interruption, such as the activation or stop of the boost function, and so on.

The advantage of this creation is that the image detection method is used to detect the blinking time of the human eye, and it is not necessary to connect the driver's body part with the mechanical parts, and the driver can act on the driver's seat, without having to use the above-mentioned conventional technology. It is quite inconvenient to wear objects for the driver, and it is not in line with the usage habits of ordinary people. Therefore, it is a practical way, and the warning method of anti-sleeping in this creation is a positive way.

In summary, the humanized design of this case is quite in line with actual needs. The specific improvement of the existing defects is obviously a breakthrough improvement advantage compared with the prior art, and it has an improvement in efficacy and is not easy to achieve. The case has not been disclosed or disclosed in domestic and foreign literature and market, and has complied with the provisions of the Patent Law.

The detailed description above is a detailed description of one of the possible embodiments of the present invention, and the embodiment is not intended to limit the scope of the patents, and the equivalent implementations or modifications that are not included in the spirit of the present invention should be included in The patent scope of this case.
