Abstract

The present invention discloses a bird' s-eye view image-producing device having a function of automatically calibrating an image. The bird's-eye view image-producing device automatically corrects a change in camera location due to a passenger getting into an automobile even if a driver does not perform a separate calibration step to produce the bird's-eye view image. The bird's-eye view image-producing device may include: a first camera and a second camera for taking images of perimeters of a vehicle to generate a first image and a second image, a tilt calibrating unit for calibrating a tilt of the first camera caused by the passenger's weight, by comparing an image acquired through the first camera when the vehicle starts with a reference image for the first camera taken before a passenger has gotten into the vehicle; and a bird's-eye view image producing unit for producing a bird's-eye view image having a perspective that views the perimeter of the vehicle from an upper part of the vehicle by combining a first image with the second image, the first image being taken by the first camera that is calibrated with regard to the tilt.
