Abstract
An apparatus for warning an obstacle of a vehicle includes an image obtaining device configured to take an image around the vehicle through image sensors. An image segmentation device is configured to segment a current reference image obtained in blocks of an object. A motion estimator is configured to estimate two dimensional motion information of the object. A variation estimator is configured to estimate distance information between the object and the vehicle. A relative motion estimator is configured to estimate three dimensional relative motion information of the object by combining the two dimensional motion information and the distance information. A collision time estimator is configured to estimate a collision time between the object and the vehicle by using the three dimensional relative motion information. An image processor is configured to adjust a brightness of a corresponding segmented block. A display is configured to display the image.
