Vehicle and method of providing rear image thereof
A vehicle includes a camera for capturing a rear image and effectively outputs a rear image captured through a mobile device when the vehicle does not include a display. A method of providing the rear image of the vehicle includes: setting a data path with a smart device, acquiring a rear image from a rear camera of the vehicle, correcting the acquired rear image based on a vehicle speed and delay that occurs in the data path, and transmitting the corrected image to the smart device.
1. A method of providing a rear image of a vehicle, the method comprising:
setting, by a processor, a data path with a smart device;
acquiring, by the processor, a rear image from a rear camera of the vehicle;
correcting, by the processor, the acquired rear image based on a vehicle speed of the vehicle and a delay that occurs in the data path; and
transmitting, by the processor, the corrected rear image to the smart device,
wherein correcting the acquired rear image includes: acquiring an image corresponding to a viewing angle to be seen at a distance at which the vehicle is reversed during the delay, and
wherein acquiring the image corresponding to the viewing angle includes: performing a zoom-in control on the rear camera proportional to the delay and the vehicle speed.
2. The method of claim 1 , wherein acquiring the rear image is performed while a transmission of the vehicle is in a rear gear stage.
3. The method of claim 1 , wherein acquiring the image corresponding to the viewing angle further includes:
cropping a predetermined range in the acquired rear image based on the delay and the vehicle speed; and
enlarging the cropped image to an original size.
4. A non-transitory computer-readable having a program recorded thereon, the program to direct a processor to perform acts of:
setting a data path between a smart device and a vehicle;
acquiring a rear image from a rear camera of the vehicle;
correcting the acquired rear image based on a vehicle speed of the vehicle and a delay that occurs in the data path; and
transmitting the corrected rear image to the smart device,
wherein correcting the acquired rear image includes: acquiring an image corresponding to a viewing angle to be seen at a distance at which the vehicle is reversed during the delay, and
wherein acquiring the image corresponding to the viewing angle includes: performing a zoom-in control on the rear camera proportional to the delay and the vehicle speed.
5. A vehicle comprising:
a rear camera; and
an image processor configured to:
set a data path between a smart device and the vehicle,
acquire a rear image from the rear camera,
correct the acquired rear image based on a vehicle speed and a delay that occurs in the data path, and
transmit the corrected rear image to the smart device,
wherein the image processor is further configured to:
acquire an image corresponding to a viewing angle to be seen at a distance at which the vehicle is reversed during the delay, and
acquire the corrected rear image by performing a zoom-in control on the rear camera proportional to the delay and the vehicle speed.
6. The vehicle of claim 5 , wherein the image processor is configured to acquire the rear image while a transmission of the vehicle is in a rear gear stage.
7. The vehicle of claim 5 , wherein the image processor is configured to:
acquire the corrected rear image by cropping a predetermined range in the acquired rear image based on the delay and the vehicle speed, and
enlarge the cropped image to an original size.
