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. Alternatively, a control signal for attitude control or running control of the vehicle may be generated as the vehicle control information.

Also, according to the embodiment, the segmentation section 432 may be omitted.

Referring to FIG. 6, during the first frame period, the camera 160 may acquire a stereo image.

The disparity calculating unit 420 in the processor 170 receives the stereo images FR1a and FR1b signal-processed by the image preprocessing unit 410 and performs stereo matching on the received stereo images FR1a and FR1b And obtains a disparity map (520).

The disparity map 520 is obtained by leveling the parallax between the stereo images FR1a and FR1b. The higher the disparity level is, the closer the distance is from the vehicle, and the smaller the disparity level is, It is possible to calculate that the distance is long.

On the other hand, when such a disparity map is displayed, it may be displayed so as to have a higher luminance as the disparity level becomes larger, and a lower luminance as the disparity level becomes smaller.

In the figure, first to fourth lanes 528a, 528b, 528c, and 528d have corresponding disparity levels in the disparity map 520, and the construction area 522, the first front vehicle 524 ) And the second front vehicle 526 have corresponding disparity levels, respectively.

The segmentation unit 432, the object detection unit 434 and the object identification unit 436 determine whether or not the segments, the object detection, and the object detection information for at least one of the stereo images FR1a and FR1b based on the disparity map 520 Perform object verification.

Hereinafter, the process of providing the vehicle auxiliary device 100 with the liquid spill prevention function will be described in more detail.

Referring to Fig. 8, the vehicle auxiliary apparatus 100 may first monitor the internal situation of the vehicle. (S101)

More specifically, the monitoring unit 165 can monitor the inside of the vehicle to obtain inside information of the vehicle.

For example, the internal camera of the monitoring unit 165 can capture the inside of the vehicle and acquire the in-vehicle image.

The infrared camera of the monitoring unit 165 can scan the inside of the vehicle by infrared rays and scan the inside temperature of the vehicle.

Thereafter, the vehicle auxiliary apparatus 100 can analyze the inside information of the vehicle obtained by monitoring the inside situation of the vehicle, and judge whether or not there is liquid in the inside of the vehicle. (S102)

More specifically, the processor 170 can analyze the in-vehicle image to determine whether there is liquid inside the vehicle by determining whether or not there is a liquid container image inside the vehicle. In detail, the processor 170 can compare the liquid container image stored in the memory 140 and the object image included in the in-vehicle image to determine the presence or absence of the liquid container.

In order to more accurately detect the liquid container, the processor 170 may detect the liquid container in such a manner that a specific object in the in-vehicle image detects an image pattern moving between the user's mouth and the vehicle liquid container carrier.

In addition, the processor 170 may analyze the infrared image of the vehicle interior to determine whether there is liquid in the vehicle. More specifically, the processor 170 can judge a specific object which is different from the reference internal temperature of the vehicle by a predetermined temperature or more as a liquid.

If it is determined that there is liquid in the vehicle, the processor 170 can analyze the liquid container to determine the characteristics of the liquid container. (S103)

In detail, the processor 170 may analyze the liquid container image to obtain a liquid container characteristic including at least one of the inlet opening and closing of the container, the liquid level inside the container, and the inclination of the container.

This characteristic of the liquid container 10 can be used to determine the risk of spilling the liquid container 10

10A, when the inlet 11 of the liquid container 10 is closed with the cork cap 12, the processor 170 can determine that the risk of liquid spillage is low.

On the other hand, as shown in FIG. 10B, when the liquid container 10 is closed with a loose lid, the processor 170 can determine that the risk of liquid spills is high.

Further, as shown in FIG. 10C, the processor 170 can determine that the risk of liquid spillage is low when detecting a can opening that is not yet open. Conversely, if the processor 170 detects that the can inlet is open, it can be determined that the risk of liquid spills is high.

Thereafter, the processor 170 may detect a liquid spill hazard situation. (S104)

In detail, the processor 170 can detect a liquid spill hazard situation through the characteristics of the liquid container 10 and the running state of the vehicle.

For example, the processor 170 may detect at least one of the following situations: detection of the liquid container 10, opening of the inlet of the liquid container 10, a situation where the user drinks liquid, and a situation where the liquid container 10 is inclined beyond a predetermined angle Can be detected as a risk of liquid spillage.

11A to 11B, when the possibility that the liquid is discharged out of the inlet of the liquid container 10 is calculated based on the liquid level 20 and the slope of the liquid, Can be detected.

Further, referring to Fig. 12, when the user detects an image pattern in which the user drinks the liquid, the processor 170 can detect the liquid spill dangerous situation.

The processor 170 may detect a liquid pouring risk condition based on the vehicle outside information as well as the vehicle inside information.

For example, the processor 170 may determine that the liquid is in a dangerous state when it detects the uneven portion in front of the vehicle.

Thereafter, when the processor 170 detects a liquid spill hazard situation, it may control the display unit 180 to display a graphic image warning of the risk of liquid spillage. (S105)

In detail, the processor 170 can warn of the risk of liquid spills through the display unit 180 and the audio output unit 185.

For example, the processor 170 may display the in-vehicle image and the image highlighting the liquid container 10 on the display unit 180, thereby alerting the user of the risk of liquid spillage.

13, the display unit 180 may display an image highlighting the liquid container 10 in the in-vehicle image to warn the user of the risk of liquid spillage.

In addition, the processor 170 can stably control the vehicle and can autonomously run the vehicle so as not to pour liquid when the risk of liquid spillage is detected during self-running of the vehicle. (S106)

In detail, the processor 170 can control the driving portion of the vehicle so that the vehicle maintains the current speed when detecting a liquid spill danger situation.

For example, when the occupant senses a situation where the occupant is drinking the liquid, the processor 170 can prevent the liquid from being spilled in advance by minimizing the shaking in the vehicle by maintaining the moving direction and the speed of the vehicle.

Further, the processor 170 can prevent the liquid from being spilled in advance by controlling the vehicle to avoid the ruggedness section and running when the risk of liquid spillage and the ruggedness section in front of the vehicle are detected.
