An image preprocessor 410 may receive an image from the camera 160 and perform preprocessing.

Specifically, the image preprocessing unit 410 may perform a noise reduction, a rectification, a calibration, a color enhancement, a color space conversion (CSC Interpolation, camera 160 gain control, and the like. Accordingly, a clearer image than the stereo image captured by the camera 160 can be obtained.

The disparity calculator 420 receives the image signal processed by the image preprocessing unit 410, performs stereo matching on the received images, and performs disparity calculation based on stereo matching, A disparity map can be obtained. That is, it is possible to obtain the disparity information about the stereo image with respect to the front of the vehicle.

At this time, the stereo matching may be performed on a pixel-by-pixel basis of stereo images or on a predetermined block basis. On the other hand, the disparity map may mean a map in which binaural parallax information of stereo images, i.e., left and right images, is numerically expressed.

The segmentation unit 432 may perform segmenting and clustering on at least one of the images based on the disparity information from the disparity calculating unit 420. [

Specifically, the segmentation unit 432 can separate the background and the foreground for at least one of the stereo images based on the disparity information.

For example, an area having dispaly information within a disparity map of a predetermined value or less can be calculated as a background, and the corresponding part can be excluded. Thereby, the foreground can be relatively separated. As another example, an area in which the dispetity information is equal to or greater than a predetermined value in the disparity map can be calculated with the foreground, and the corresponding part can be extracted. Thereby, the foreground can be separated.

Thus, by separating the foreground and the background based on the disparity information information extracted based on the stereo image, it becomes possible to shorten the signal processing speed, signal processing amount, and the like at the time of object detection thereafter.

Next, the object detector 434 can detect the object based on the image segment from the segmentation unit 432. [

That is, the object detecting unit 434 can detect an object for at least one of the images based on the disparity information.

More specifically, the object detecting unit 434 can detect an object for at least one of the images. For example, an object can be detected from a foreground separated by an image segment.

The object verification unit 436 then classifies and verifies the isolated object.

For this purpose, the object identifying unit 436 identifies the objects using a neural network identification method, a SVM (Support Vector Machine) method, a AdaBoost identification method using a Haar-like feature, or a Histograms of Oriented Gradients (HOG) Technique or the like can be used.

On the other hand, the object checking unit 436 can check the objects by comparing the objects stored in the memory 140 with the detected objects.

For example, the object identifying unit 436 can identify nearby vehicles, lanes, roads, signs, hazardous areas, tunnels, etc., located in the vicinity of the vehicle.

The object tracking unit 440 may perform tracking on the identified object. For example, it sequentially identifies an object in the acquired stereo images, calculates a motion or a motion vector of the identified object, and tracks movement of the object based on the calculated motion or motion vector . Accordingly, it is possible to track nearby vehicles, lanes, roads, signs, dangerous areas, tunnels, etc., located in the vicinity of the vehicle.

Next, the application unit 450 can calculate the risk of the vehicle and the like based on various objects located in the vicinity of the vehicle, for example, other vehicles, lanes, roads, signs and the like. It is also possible to calculate the possibility of a collision with a preceding vehicle, whether the vehicle is slipping or the like.

Then, the application unit 450 can output a message or the like for notifying the user to the user as vehicle driving assistance information, based on the calculated risk, possibility of collision, or slip.
