The camera 110 is installed at a horizontal position with respect to the rear blind spot of the vehicle or at a position where a blind spot can be seen. For example, as shown in Fig. 2, in a shark-like casing 10 installed at the rear of the vehicle roof.

In this embodiment, the camera 110 may be a wide angle camera in order to maximize the viewing angle.

The vehicle information acquiring unit 130 acquires vehicle information of at least one of a steering angle of a vehicle, a turn signal lamp, and a transmission gear (traveling, reverse) from an ECU (not shown) of the vehicle, And outputs the generated drive signal to the camera driver 120. The camera driver 120 generates a drive signal for determining a direction and a rotation angle of the camera.

For example, when the vehicle is traveling, when the steering angle is 0 degree in the frontal running, the camera 110 displays the rear full image when the steering angle is 0 degrees and the center and the rear side when the steering angle is 0 degrees or less And generates and outputs a driving signal for driving the camera 110 to face the right so that the center and the rear of the rear are represented to be 0 degrees or more (right side) . That is, the direction that the camera 110 faces can be determined according to the direction of the steering angle.

Here, the expression position may be changed according to the transmission gear information (traveling, reverse).

In addition, the direction in which the camera 110 is directed may be determined according to the type of turn-on direction indicator lamp (such as the left side or the right side). The degree to which the camera 110 is directed to the left or the right may be determined according to the magnitude of the steering angle.

The camera driver 120 rotates the camera 110 in accordance with the rotation direction and / or the rotation angle of the camera 110 determined according to the vehicle information acquired by the vehicle information acquisition unit 130. The camera driving unit 120 may be a stepping motor capable of adjusting the rotation angle, for example.

The image analysis unit 140 analyzes the image data photographed by the camera 110. When the camera 110 changes the rotation direction and the rotation angle from the default value, the camera driver 120 reflects the rotation direction and the rotation angle so that the image data analysis is performed.

The image analysis unit 140 recognizes an obstacle that may be a risk factor in the vehicle in the image data photographed by the camera 110. [ For example, the vehicle behind the vehicle can be identified by size, relative position can be determined, and the speed of the nearby vehicle can be analyzed. Obstacle recognition, relative position detection and speed analysis according to the image data analysis are obvious to those skilled in the art, and detailed description will be omitted.

The image synthesis unit 150 generates a synthetic image that allows the driver to view a blind zone image based on the analysis result, based on the analysis result of the image analysis unit 140.

First, the image synthesizing unit 150 generates the composite image as it is, so that the photographed image is displayed as it is, or the information about the rotation direction and the rotation angle of the camera 110 is, for example, , A number, a symbol, or the like.

In addition, if there is a risk factor in a blind spot as a result of the analysis of the image data, the risk may be emphasized in the basic image data so that the driver can pay attention to the risk factor.

Or a state in which the driver is able to easily see the running state of the vehicle located in a dead zone behind the current vehicle. An example in which the running state of the rear vehicle is represented on a virtual map is shown in Fig. Here, when the rear vehicle 32, which can become a dangerous element, enters the dangerous area 22 set in advance on the rear surface of the target vehicle 22, the driver can easily confirm .

The display unit 160 displays the synthesized image synthesized by the image synthesizer 150. Display portion 160 may be, for example, a display unit, a room mirror display, or a head-up display (HUD) attached or embedded on the front panel of the vehicle. Or the display unit 160 may be a screen of a predetermined terminal (e.g., a driver's smartphone) connected through a network.

In this system, if a risk element enters the dangerous area 22, it may provide auditory notification through a speaker (not shown) in addition to a visual notification through a visual image.

FIG. 7 is a view showing the progress of the incident light according to the change of the mirror property, and FIG. 8 is a view showing the progress of the incident light according to the mirror driving.

The blind spot detection system according to another embodiment of the present invention can detect an object positioned behind and a side by using a pair of mirrors and a single camera so that the position of the surrounding vehicle can be intuitively determined, And thus the accident can be alleviated.

The blind zone detection system 200 according to the present embodiment includes a camera 210, a mirror 220, a mirror driving unit 230, a vehicle information obtaining unit 240, an image analyzing unit 250, an image synthesizing unit 260, And a display unit 270.

The camera 210 is installed so as to face the rear of the vehicle, and photographs a rear image of the vehicle. The camera 210 is installed at a horizontal position with respect to the rear blind spot of the vehicle or at a position where a blind spot can be seen. For example, as shown in Fig. 2, in a shark-like casing 10 installed at the rear of the vehicle roof.

A pair of mirrors 220a and 220b (hereinafter also referred to as '220') may be installed in the shake-type case 10 as shown in FIGS.

6, the image sensor 212 included in the camera 210 may be partitioned into three zones 212a to 212c, corresponding to the left zone 212a and the right zone 212c, A mirror 220 may be installed. In other words, the image sensor 212 can be partitioned into a left area 212a, a center area 212b and a right area 212c, a light beam Lb immediately behind the center area 212b is incident, The light La1 or La2 through the first mirror 220a is incident on the first mirror 212a and the light Lc1 or Lc2 through the second mirror 220b is incident on the right mirror 212c.

The space in front of the image sensor 212 may also be partitioned into a left space 1, a center space 2 and a right space 3 along the boundary line of the image sensor 212. In this case, the first mirror 220a is installed in the left space (area 1) by a predetermined angle, and the second mirror 220b is installed in the right space (area 3) do. Here, the first mirror 220a and the second mirror 220b may be fixed while being rotated so as to have a predetermined inclination sideways with respect to the optical axis of the image sensor 212. [

In this embodiment, the mirror 220 may have a variable property to transmit or reflect light according to an electric signal applied from the mirror driver 230. Here, the mirror 220 may be a switchable mirror, or may be a device such as a color conversion liquid crystal display unit or an active mirror.

When the first electric signal is applied to the mirror 220, the mirror 220 is changed to a transmission type so that light traveling in the rear direction is transmitted to the image sensor 212. When the second electrical signal is applied, the light is converted into a reflection type so that the light proceeding from the rear is blocked and the light proceeding from the side is reflected to be directed to the image sensor 212.

7, when the first electric signal is applied to the first mirror 220a, the light La1 immediately after the first electric signal is incident, and when the second electric signal is applied, the light La2 on the left rear is reflected, . When the first electric signal is applied to the second mirror 220b, the light Lc1 of the immediately following room is incident as it is. When the second electric signal is applied, the right rear light Lc2 is reflected and incident.

Therefore, according to the electric signal applied from the mirror driving unit 230, the camera 210 can acquire a wide range of images immediately after the room or acquire left and right rear images together with the rear image.

When the mirror 220 operates in a reflective mode, it is possible to photograph the side rear image which can not be confirmed due to the viewing angle limitation of the camera 210, by the camera 210.

Further, when the mirror 220 operates in the reflective mode, at least one of the rotation direction and the rotation angle can be adjusted by the mirror driving unit 230. [

8, when the mirrors 220a and 220b are rotated in the direction perpendicular to the longitudinal direction of the vehicle, the direction of the light incident on the image sensor 212 can be more steeply curved, Can be obtained more widely. That is, in FIG. 8 (a), the camera 210 has a viewing angle of? 1 and the viewing angle of? 2 in FIG. 8 (b).

The image analysis unit 250 analyzes the image acquired by the camera 210. For example, when a first electrical signal is applied to the first mirror 220a and the second mirror 220b, the respective zones 212a to 212c of the image sensor 212 acquire images of the immediately following room Respectively. When a second electric signal is applied to at least one of the first mirror 220a and the second mirror 220b, it is determined that the image of the image sensor 212 is obtained with respect to the corresponding region, do.

When the first mirror 220a and the second mirror 220b operate in a reflective mode, the image input to the left and right regions 212a and 212b of the image sensor 212 is reflected by the mirror 220 So that the image analysis is performed in accordance with the change.

The image synthesis unit 260 synthesizes images of the respective regions acquired by the image sensor 212 according to the analysis result of the image analysis unit 250.

For example, when all the regions are related to the image of the immediately following room, the images of the respective regions can be matched and synthesized into one rear image. When one or more zones are related to the image behind the room, the images acquired in each zone are sequentially displayed so that they can be displayed separately from the images in the immediately following room, the frames are divided so that they can be divided into zones, (E.g., letters, numbers, symbols, etc.) are superimposed on each other.

Also, if there is a risk factor in the blind spot as a result of the analysis of the image data, the risk may be emphasized and synthesized so that the driver can pay attention to the risk factor.

(See FIG. 3) so that the driver can easily see the driving state of the vehicle located at the rear of the vehicle in a dead zone around the current vehicle. Here, when a rear vehicle, which may become a dangerous element, enters a dangerous area 22 previously set in the rear surface of the vehicle, the driver can easily confirm the vehicle in a manner of expressing or flashing in a prominent color.

The display unit 270 displays the synthesized image on the screen. The display portion 270 may be, for example, a display unit, a room mirror display, or a head-up display attached or embedded on the front panel of the vehicle. Or the display unit 270 may be a screen of a predetermined terminal (e.g., a driver's smartphone) connected through a network.

According to the present embodiment, even if the camera is not a wide-angle camera, it is possible to acquire a side image using a mirror, thereby securing a wide viewing angle, enabling wide detection of a blind spot in the rear of the vehicle.
