Abstract

Disclosed is a vehicle, including a display device; one or more cameras; and a controller configured to combine a plurality of images received from the one or more cameras and switch the combined image to a top view image to generate an around view image, detect an object from at least one of the plurality of images and the around view image, determine a weighted value of two images obtained from two cameras of the one or more cameras when an object is located in an overlapping area in views of the two cameras, assign a weighted value to a specific image of the two images from the two cameras with the overlapping area, and display the specific image with the assigned weighted value and the around view image on the display device.

Claims

1. A vehicle, comprising:

a display device;

one or more cameras; and

a controller configured to;

combine a plurality of images received from the one or more cameras and switch the combined image to a top view image to generate an around view image,

detect an object from at least one of the plurality of images and the around view image,

determine a weighted value of two images obtained from two cameras of the one or more cameras when an object is located in an overlapping area in views of the two cameras,

assign a weighted value to a specific image of the two images from the two cameras with the overlapping area, and

display the specific image with the assigned weighted value and the around view image on the display device.

2. The vehicle of claim 1, wherein the one or more cameras comprise:

a first camera configured to obtain an image around a left side of the vehicle;

a second camera configured to obtain an image around a rear side of the vehicle;

a third camera configured to obtain an image around a right side of the vehicle; and

a fourth camera configured to obtain an image around a front side of the vehicle.

3. The vehicle of claim 2, wherein:

when the weighted value is assigned to the specific image from the first camera, the controller displays the image around the left side of the vehicle at a left side of the around view image on the display device,

when the weighted value is assigned to the specific image from the second camera, the controller displays the image around the rear side of the vehicle at a lower side of the around view image on the display device,

when the weighted value is assigned to the specific image from the third camera, the controller displays the image around the right side of the vehicle at a right side of the around view image on the display device, and

when the weighted value is assigned to the specific image from the fourth camera, the controller displays the image around the front side of the vehicle at an upper side of the around view image on the display device.

4. The vehicle of claim 1, wherein the display device comprises a touch input unit and when the touch input unit receives a touch input for the object displayed on the specific image with the assigned weighted value, the controller enlarges the object and displays the enlarged object.

5. The vehicle of claim 1, wherein the display device comprises a touch input unit and when the touch input unit receives a touch input for the object displayed on the specific with the assigned weighted value, the controller controls the camera associated with weighted value to zoom in.

6. A vehicle, comprising:

a display device;

one or more cameras; and

a controller configured to;

combine a plurality of images received from the one or more cameras and switch the combined image to a top view image to generate an around view image,

detect an object from at least one of the plurality of images and the generated around view image,

determine a weighted value of two images obtained from two cameras of the one or more cameras based on a disturbance generated in the two cameras when the object is located in an overlapping area in views of the two cameras, and

display the around view image on the display device.

7. The vehicle of claim 6, wherein when disturbance is generated in one camera between the two cameras, the controller assigns a weighted value of 100% a specific image from the camera of the two cameras without the generated disturbance.

8. The vehicle of claim 6, wherein the disturbance is at least one of light inflow, exhaust gas generation, lens contamination, low luminance, image saturation, side mirror folding, and trunk opening.

9. The vehicle of claim 6, wherein the controller determines a weighted value through at least one of a score level method and a feature level method.

10. The vehicle of claim 9, wherein when the controller determines the weighted value through the score level method, the controller determines the weighted value by assigning an AND condition or an OR condition to the images obtained by the two cameras.

11. The vehicle of claim 9, wherein when the controller determines the weighted value through the feature level method, the controller determines the weighted value by comparing at least one of movement speeds, directions, and sizes of the object obtained in the at least one of the plurality of images and the generated around view image.

12. The vehicle of claim 11, wherein when the controller determines the weighted value based on the movement speed of the object, the controller compares the images obtained by the two cameras and assigns the weighted value to a specific image obtained by the two cameras having a larger object pixel movement amount than the other image obtained by the two cameras.

13. The vehicle of claim 11, wherein when the controller determines the weighted value based on the directions of the object, the controller compares the images obtained by the two cameras and assigns the weighted value to a specific image having a larger horizontal movement than the other image obtained by the two cameras.

14. The vehicle of claim 11, wherein when the controller determines the weighted value by comparing the sizes of the object, the controller compares the images obtained by the two cameras and assigns the weighted value to a specific image having a larger area of a virtual quadrangle surrounding the object than the other image obtained by the two cameras.

15. A vehicle, comprising:

a display device;

one or more cameras; and

a controller configured to;

receive a plurality of images related to a surrounding area of the vehicle from one or more cameras,

determine whether an object is detected from at least one of the plurality of images,

determine whether the object is located in at least one of a plurality of overlap areas of the plurality of images,

process the at least one of the plurality of overlap areas based on object detection information when the object is located in the overlap area, and

perform blending processing on the at least one of the plurality of overlap areas according to a predetermined rate when the object is not detected or the object is not located in the at least one of the plurality of overlap areas to generate an around view image.

16. The vehicle of claim 15, wherein when the object is detected in the at least one of the plurality of overlap areas of the plurality of images, the controller compares at least one of movement speeds, movement directions, and sizes of the object in the plurality of images, determines a specific image of the plurality of images having higher reliability than other images of the plurality of images, and processes the at least one of the plurality of overlap areas based on the higher reliability of the specific image.

17. The vehicle of claim 16, wherein the controller processes the at least one of the plurality of overlap areas only with the specific image having the higher reliability.

18. The vehicle of claim 17, wherein when the controller determines reliability based on the movement speed, the controller assigns a higher reliability rating to the specific image of the plurality of images having a larger pixel movement per unit of time compared to the other images of the plurality of images.

19. The vehicle of claim 17, wherein when the controller determines reliability based on the movement direction, the controller assigns a higher reliability rating to the specific image of the plurality of images having a larger horizontal movement compared to the other images of the plurality of images.

20. The vehicle of claim 17, wherein when the controller determines reliability based on the size, the controller assigns a higher reliability rating to the specific image of the plurality of images having a larger number of pixels occupied by the object compared to the other images of the plurality of images.
