METHOD AND APPARATUS FOR WARNING AN OBSTACLE OF A VEHICLE

摘要

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.

1. An apparatus for warning an obstacle of a vehicle comprising:
an image obtaining device configured to take an image around the vehicle through at least two image sensors; an image segmentation device configured to segment a current reference image obtained through one image sensor among the at least two image sensors in blocks of an object; a motion estimator configured to estimate two dimensional motion information of the object in each of segmented blocks segmented by the image segmentation device; a variation estimator configured to estimate distance information between the object in a segmented block and the vehicle; a relative motion estimator configured to estimate three dimensional relative motion information of the object in the segmented block by combining the two dimensional motion information and the distance information; a collision time estimator configured to estimate a collision time between the object in the segmented block and the vehicle by using the three dimensional relative motion information; an image processor configured to adjust a brightness of a corresponding segmented block in a pre-defined ratio according to the collision time; and a display configured to display an image processed by the image processor.
