The SVM image generator may include a memory, an image converter, a detector, an image synthesizer, and an image corrector.

The front, rear, left, and right images of the vehicle photographed by the front camera 21, the rear camera 22, the left camera 23, and the right camera 24 respectively generate SVM (Surround View Monitoring) To-image converter.

The memory stores various setting values for the operation of the SVM system, and status information and results for each operation can be stored. For example, the memory may store SVM images of a car and SVM images of surrounding vehicles, and may store SVM images of a car and SVM images of surrounding vehicles. The memory may also store an image synthesis algorithm for the synthesis of SVM images.

The memory may be a flash memory type, a hard disk type, a solid state disk type, an SDD type (Silicon Disk Drive type), a multimedia card micro type, (RAM), static random access memory (SRAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM) ), A programmable read-only memory (PROM), a magnetic memory, a magnetic disk, and an optical disk.

The image converter generates the SVM image of the car from the image around the car taken by the camera 20. [ At this time, the image converter can view-convert the image photographed in the vicinity of the car to a top view image in order to generate the SVM image.

The image converter can convert the SVM image of the surrounding vehicle inputted from the outside. At this time, the image converter grasps the relative position between the vehicle and the surrounding vehicle based on the position of the vehicle and the surrounding vehicle, and converts the SVM image of the surrounding vehicle based on the position of the vehicle. As an example, the video converter compares the position and direction of the vehicle with the position and direction of the surrounding vehicle to move the SVM image of the surrounding vehicle relative to the position of the vehicle, and rotates the SVM image of the surrounding vehicle based on the vehicle direction do. Here, if the direction of the surrounding vehicle is the same as the direction of the vehicle, the SVM image of the surrounding vehicle may not be rotated.

The detector compares the SVM image of the vehicle with the SVM image of the surrounding vehicle and detects the overlapping area between the SVM image of the vehicle and the SVM image of the surrounding vehicle.

The image synthesizer synthesizes the SVM image of the car with the SVM image of the surrounding vehicle based on the overlapping area detected by the detector. At this time, the image synthesizer can assign a weight based on at least one of a straight line component, a distance value, and a pixel value of the SVM image of the own vehicle and the SVM image of the neighboring vehicle, The SVM image of the car and the SVM image of the surrounding vehicle can be synthesized based on the weighted sum by calculating the weighted sum of the weights.

The image synthesizer can synthesize the SVM image of the surrounding vehicle on the SVM image of the car in synthesizing the SVM image of the car and the surrounding vehicle. In this case, the synthesized SVM image has the same visible range as the SVM image of the vehicle.

The image synthesizer can generate the synthesized SVM image including both the SVM image of the car and the SVM image of the surrounding vehicle.

When synthesizing a continuous SVM image, the image synthesizer can synthesize each SVM image based on the trajectory information of the corresponding vehicle, and can synthesize the SVM image based on the feature points of each SVM image in addition to the overlap area.

The image corrector corrects the boundary area and the blank area of the SVM image synthesized by the image synthesizer. As an example, the image compensator may blend the boundary region to minimize image distortion when composing each SVM image. For the area where the weighted sum is small or the information is absent, the surrounding information of the corresponding vehicle may be blended. Note that you can interpolate or treat it as an empty space.

Next, the control unit 250 performs overall control so that the respective components can perform the functions normally.

Particularly, when the door opening is sensed by the door sensor 210 and the image acquisition unit 220 is activated, the control unit 250 detects an opening angle of the door based on the image acquired by the image acquisition unit 220 can do.

Thereafter, the control unit 250 controls the alarm unit 240 to activate the start blocking unit 230 and output an alarm sound if the detected angle exceeds the reference angle when the driver operates the accelerator pedal, if the detected angle exceeds the reference angle . At this time, the control unit 250 is connected to the vehicle network, so that it can confirm whether or not the Excel pedal is operated.

Here, the vehicle network includes a CAN (Controller Area Network), a LIN (Local Interconnect Network), a FlexRay, a MOST (Media Oriented Systems Transport), and the like.

In addition, the control unit 250 may further include a sensing unit (not shown) for sensing the operation of the excel pedal to detect whether the driver operates the excel pedal.

In addition, the controller 250 may detect the opening degree of the door through image comparison without detecting the opening angle of the door in the image. That is, the reference image may be stored in a self-contained memory (not shown), and the image obtained by the image obtaining unit 220 may be compared with the reference image to detect the degree of opening of the door. Of course, this method is preferably applied to the rear door.

FIG. 5 is a view showing another embodiment of a passenger protecting apparatus for a vehicle according to the present invention, wherein the same functional elements as those shown in FIG. 2 are assigned the same reference numerals.
