Specifically, the CAN communication unit 177 performing the internal communication role performs the same function as the internal communication unit 220 shown in FIG. 2, and the wireless communication unit 178 performing the external communication role functions as the wireless communication unit 300 can perform the same function.

Therefore, the communication unit 176 included in the surrounding view monitoring system 170 secures the information acquired from the various electronic devices 100 of the vehicle through the CAN communication unit 177, And transmits a warning message to the terminal 1.

4, the image obtaining unit 171 photographs a surrounding image by the front camera a, the left camera b, the rear camera c, and the right camera d. , The external image of the vehicle can be photographed and the photographed information can be generated.

Specifically, a camera sensor usually uses a camera having more than one channel, and a CMOS (Complementary Metal Oxide Semiconductor) can be used as the image sensor. A CMOS image sensor is a semiconductor device that converts exposed images into electrical form and transmits them.

However, the present invention is not limited thereto, and may be realized by a CCD (Change Coupled Device) image sensor (not shown). Thus, the camera sensor can be installed at a plurality of positions of the vehicle to obtain the front, rear, and side images of the vehicle.

Therefore, it is possible to take a picture of a parking space in a peripheral area of the present vehicle based on the plurality of camera sensors (a to d), to take an Around View (AVM) system Monitor to the electronic control unit 172 of the surrounding view monitoring system 170 through the CAN communication unit 177. [

Specifically, as shown in Fig. 4, a rectangle-shaped ROI formed by a predetermined distance to the front of the vehicle, a preset distance to the vehicle side, and a predetermined distance to the rear of the vehicle may be set.

In addition, when the vehicle parking line is detected in the video secured through the plurality of camera sensors (a to d), the determination unit 173 may reflect the sensed line on the top view and display it. Specifically, Fig. 5 is a schematic view showing a case in which a line of the parking lot is photographed by the rear camera (d) and is reflected and displayed in the top view.

In addition, the determination unit 173 may display the lines and obstacles in the top view when a plurality of camera sensors (a to d) detect a line displayed in the parking lot and an obstacle is detected.

For example, as shown in FIG. 5, the determination unit 173 generates a top view including another vehicle based on the image acquired by the image acquisition unit 171.

In addition, the determination unit 173 determines whether an obstacle is detected within the set ROI area. That is, when it is determined that the vehicle is to be parked, as in the case where the parking line is detected, the determination unit 173 determines whether or not the operation of the various electronic devices 100 of the vehicle through the CAN communication unit 177 in the communication unit 176 And estimates the expected route of the vehicle.

Accordingly, the determination unit 173 can display the estimated route in dotted line form as shown in FIG. 5 so that the driver can confirm the estimated route.

The control unit 174 controls the communication unit 176 to display the top view generated by the determination unit 173 on the terminal 1 so that the driver can detect the ROI area generated by the determination unit 173. [ As shown in Fig. 4 and Fig. 5, by a dotted line or the like.

In addition, the control unit 174 may control the image acquired through the image acquisition unit 171 to be displayed on the user's terminal 1 as it is.

Accordingly, for example, the control unit 174 may be configured to transmit the forward image information acquired by the driver through the forward camera sensor (a) on the basis of the operation information of the vehicle received via the CAN communication unit 177, It is also possible to control the display of the rear image information acquired through the rear camera sensor (c) together with the top view.

That is, the control unit 174 collectively controls the determination unit 173 and the warning unit 175 in the electronic control unit 172 to generate a top view on the basis of the image of the image obtaining unit 171, The top view can be collectively controlled to be transmitted to the terminal through the communication unit 176. [

If there is an obstacle in the generated ROI area, the warning unit 175 displays an obstacle in the ROI area such that the color of the displayed ROI is different, or the displayed ROI is blinked so that the driver can check it. Warn to be able to confirm.

In addition, the surrounding view monitoring system 170 according to the present invention may acquire a sensing signal from a sensor that detects an obstacle around the vehicle other than the image through the communication unit 176. [

For example, the distance to the obstacle is detected through the radar sensor or the laser sensor included in the obstacle detection module 190, and the detected distance is compared with the position of the obstacle acquired through the image acquisition unit 171 The position of the obstacle in the top view in the electronic control unit 172 may be corrected.
