Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video recording system for a vehicle,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle image recording apparatus (vehicle black box).

Vehicle video recording apparatuses are widely used.

Vehicle video recording devices are often referred to as black boxes, after the name of the device for storing the flight record of an aircraft.

In general, a video recording apparatus stores an image using a camera installed forward or backward when the vehicle is running.

Therefore, when an accident occurs while driving, it is possible to clearly identify the accident situation through the image recorded by the vehicle black box, and it is possible to hide the perpetrator and the victim or to determine the failure rate.

If an accident occurs while the driver is driving the vehicle, the driver can recognize the accident immediately and contact the insurance company on the spot. However, when the driver parks the vehicle If there is an accident such as a shock to the vehicle, the operator should check the CCTV if there is CCTV installed in the place to check who is the injured vehicle or the perpetrator, specify the time of the accident when watching CCTV, If you do, you have to go through a very cumbersome process, such as identifying the number of the injured vehicle from the video, contacting the assailant in cooperation with the investigating agency.

In order to solve such a hassle, recently, the video recording devices for vehicles are provided with separate power sources even when the vehicle is not started, thereby recording front and rear images of the vehicles in the paused state.

Accordingly, when an accident occurs such as a shock to the vehicle while the vehicle is being emptied, the operator can prepare a countermeasure by using the information recorded in the video driving recorder.

Nevertheless, according to this conventional technique, the operator can return to the vehicle and recognize the occurrence of an accident.

In addition, it is only through the process of transferring the images recorded in the vehicle image recording device to the computer and reproducing it, so that only the user can easily know what happened during his absence. Therefore, although the inconvenience of accident handling and response is somewhat improved, unlike the case where an accident occurs during operation, quick initial response is still impossible.

In order to solve such a problem, it is necessary to develop a method for enabling rapid accident handling and response by notifying the driver in real time when an accident such as a shock is applied to the vehicle from the outside while the driver is parking the vehicle and leaving the seat vacant Do.

1 is a view for explaining a connection relationship between a black box for a vehicle and a mobile.

1, the vehicle black box 110 is installed inside the vehicle and is connected to the user mobile 120 by a wireless communication method.

The vehicle black box 110 may preferably be installed forward to the rear of the room mirror of the vehicle.

The vehicle black box 110 captures an image of the vehicle during driving or driving by using a built-in camera or a separately connected camera, like a known black box for a vehicle.

Meanwhile, the vehicle black box 110 according to the present invention generates and transmits an alarm message to the registered user's terminal 120 as a predetermined impact is applied to the vehicle.

In response to a request from the user mobile 120, a video image at the time when an alarm message is generated is provided by a streaming method.

The user mobile 120 is connected to the vehicle black box 110 by a Wifi communication method and displays an alarm message provided by the black box 110 on the screen or displays the alarm message provided from the black box 110 The received streaming video is played back and displayed on the screen.

2 is a functional block diagram illustrating a structure of a vehicle image recording system having an event notification function via Wi-Fi according to the present invention.

2, the vehicle video recording system 100 having an event notification function via Wi-Fi according to the present invention includes a vehicle black box 110 and a user mobile 120.

At this time, the vehicle black box 110 includes a camera 111, an encoding means 112, an impact detection sensor 113, and a control means 114.

On the other hand, the user mobile 120 includes a Wi-Fi adapter 121, a message processing unit 122, and an image processing unit 123.

Fig. 3 is a view showing an outline of a black box for a vehicle.

First, the structure of the vehicle black box 110 will be described in detail with reference to FIGS. 2 and 3. FIG.

The camera 111 photographs the inside or the outside of the vehicle.

In the case of photographing the outside, it is preferably installed toward the front or rear of the vehicle so that the front or rear of the vehicle can be photographed.

When the inside of the vehicle is photographed, it is possible to photograph a state in which the driver is installed, particularly in the direction of the driver's seat.

As shown in FIG. 2, the camera 111 may be integrally mounted in the housing of the vehicle black box 110. However, the camera 111 may be installed at a position separated from the housing of the vehicle black box 110, To the inside of the housing of the vehicle black box 110 through the opening of the black box 110 of the vehicle.

The camera 111 can use a known one.

The encoding means 112 compresses the moving picture photographed by the camera 111 by a predetermined codec.

It can be compressed using a known codec, or it can use an existing hardware codec chipset.

The impact detection sensor 113 detects an impact applied to the vehicle.

The shock detection sensor 113 may be mounted at any position, such as inside the bonnet of the vehicle, away from the housing of the black box 110, As shown in FIG.

Such an impact sensor 113 may be of a ready-made type.

On the other hand, the control unit 114 generates an alarm message using the image photographed by the camera 111 and the detection result of the impact sensor 113, as described later.

The Wi-Fi host 115 communicates with the user mobile 120 according to the Wi-Fi communication standard.

Preferably, the Wi-Fi host 115 may operate as a known Wi-Fi AP or directly communicate with the user mobile 120 according to the Wi-Fi Direct specification.

According to the commercialized Wi-Fi standard, a comparatively wide bandwidth can be secured as compared with other wireless communication methods, but there is a disadvantage that the maximum communicable distance is relatively short.

If communication methods belonging to the equal range such as Miracast, a new Wi-Fi standard scheduled to be commercialized, or Widi (Wireless Display), a communication standard for real-time transmission of moving images, are adopted, communication distance can be expanded remarkably.

The process of generating an alarm message by the control means 114 is as follows.

The control unit 114 first monitors the value sensed by the impact sensor 113, and starts analyzing the image when a value equal to or greater than the threshold value is detected. Then, an alarm message is generated using the result.

When the number of the cameras 111 is more than two, if the impact sensor 113 detects a value equal to or larger than the threshold value, the control means 114 determines whether or not the image captured by each camera 111 To determine which camera captured the impact scene.

Among the images photographed by two or more cameras 111, the camera capturing the impact scene can be determined by a method of finding the object captured in the image and the focal distance of the camera 111 within a predetermined value at the time of impact detection have.

Accordingly, the control means 114 can determine the camera 111 that captured the impact scene, and can determine the direction of the impact applied to the vehicle using the direction information of each camera 111 installed.

On the other hand, if the subject has not collided with the vehicle, such as the absence of the camera 111 capturing the impact scene, even if the impact sensor 113 detects a value greater than or equal to the threshold value, it may be an error caused by shaking or noise, The means 114 is terminated because no effective impact has occurred.

On the other hand, if there is a camera 111 capturing an impact scene, the camera 111 analyzes the captured image to determine which of the predetermined types the impact scene corresponds to.

For example, the impact on a vehicle can be divided into several types such as collision between vehicles, collision between a vehicle and a person, impact on a vehicle caused by other small objects, and the like. have.

When the distance between the camera 111 and the subject approaches within a predetermined value, it is possible to judge according to the size of the subject caught on the screen.

Through this process, the control means 114 can determine the type of impact applied to the vehicle.

On the other hand, if it is determined that the type of the impact is a collision between the vehicles, the control means 114 determines that the inside of the rectangle is filled with monochrome such as white from the images before and after the impact time, Area.

Then, the detected area is read by the OCR (Optical Character Reader) technology to detect the number of the injured vehicle which collided with the vehicle of the operator.

Furthermore, the built-in clock is used to collect time information on the impact.

Then, an alarm message including at least one of an impact direction, an impact type, a number of another vehicle that impacted the vehicle, and impact time information is generated.

That is, the alarm message may include the type of impact or the image analysis result determined by the control means 114.

The alarm message may simply be a short text message indicating when an impact has been applied to the vehicle, but may be in the form of multimedia content including a still image based on the analysis result and the analysis result.

Meanwhile, as the alarm message is generated, the control means 114 transmits the alarm message to the user mobile 120 connected to the Wi-Fi host 115.

Alternatively, the control means 114 may separately transmit the video image captured by the camera 111 and encoded by the encoding means 112, in response to a request from the user mobile 120 connected to the Wi-Fi host 115, Or may provide an image viewed through the camera 111 in real time by a streaming method.

Meanwhile, the control unit 114 may further include information indicating the position of the encoded image by the encoding unit 112 when the alarm message is generated.

The user mobile 120 touches the black box 110 to display the image of the position included in the alarm message by touching the "confirm image" button on the idle screen of the user mobile 120, Lt; / RTI >

Accordingly, the control means 114 transmits the image from the corresponding position to the user mobile 120 by the streaming method.

However, the user mobile 120 can not always be connected to the WiFi host 115 of the vehicle black box 110.

The connection between the vehicle black box 110 and the user mobile 120 is canceled according to various circumstances such that the user parks the vehicle and moves to a place beyond the Wi-Fi communication distance, or Wi-Fi communication of the user mobile 120 is disabled, .

If the control means 114 generates an alarm message immediately upon occurrence of an impact and attempts to transmit to an already registered user mobile 120, if a WiFi connection with the user mobile 120 is not established, Lt; / RTI > fails.

That is, the alarm message generated by the control means 114 can not reach the user mobile 120.

In order to solve this problem, the control unit 114 preferably generates an alarm message to check whether the WiFi host 115 and the user mobile 120 are connected according to the WiFi communication standard.

If the Wi-Fi connection is established, as described above, an alarm message is transmitted to the user mobile 120.

On the other hand, if the Wi-Fi connection is not established, the generated alarm message is registered in the alarm message queue and waits for connection with the user mobile.

Then, when a WiFi connection establishment event with the user mobile 120 occurs, it is determined whether or not the established user mobile 120 matches the pre-registered one.

If the user mobile 120 is already registered, the alarm message registered in the queue is transmitted to the user mobile 120 and deleted from the queue.

Accordingly, when the Wi-Fi connection with the user mobile 120 is released, the generated alarm message can be transmitted by waiting for the connection to be established again.

4 is a view illustrating an example in which an alarm message from a vehicle black box is displayed on a screen of a user mobile.

Hereinafter, the configuration of the user mobile 120 will be described in detail with reference to FIG. 2 and FIG.

The Wi-Fi adapter control means 121 of the user mobile 120 communicates with the Wi-Fi host 115 of the vehicle black box 110 according to the Wi-Fi communication standard.

Strictly controls the Wi-Fi adapter mounted on the user mobile 120 to process wireless communication with the Wi-Fi host 115. [

When the alarm message is received from the vehicle black box 110 via the Wi-Fi adapter 121, the message processing means 122 displays the alarm message on the screen.

The alarm message may be displayed in a pop-up form on the idle screen of the user mobile 120 as shown in FIG. 4 (a).

The alarm message may include at least one of the impact direction applied to the vehicle, the type of impact, the number of another vehicle that impacted the vehicle, and the impact time information.

The user can directly access the image at the time of the impact indicated by the alarm message by pressing the "OK" button to remove the pop-up or by pressing the "CHECK IMAGE"

On the other hand, when the user presses "confirm image" on the alarm message pop-up or activates the "image confirmation" function separately by executing the dedicated app, the image processing means 123 can display the black An image before and after the generation time of the alarm is received from the box 110 by a streaming method and displayed on the screen.

[First Embodiment]
