Abstract: The present invention relates to three-dimensional visualization of the surrounding images of a vehicle, and comprises the steps of: enabling a plurality of wide angle cameras provided at a vehicle to receive a plurality of photographed images for reference patterns formed on the ground; extracting feature points from the photographed reference patterns and estimating a relative location and an installation angle of each camera using the known physical location information of the extracted feature points; obtaining optical parameters comprising an optical center of a lens for correcting lens distortion using the photographed images and mapping each image on a surface of a Gaussian sphere using the obtained optical center; changing an angle and distance such that the Gaussian sphere and the real reference patterns correspond to each other using the relative location and the installation angle of the estimated camera and arranging the images in a three-dimensional virtual space; and obtaining a three-dimensiona

Abstract: The present invention relates to a device and method for detecting a three-dimensional object using a plurality of cameras that are capable of simply detecting a three-dimensional object. The device comprises: a planarization unit for planarizing, through homography conversion, each input image obtained by the plurality of cameras; a comparison-area selecting unit for selecting each area to be compared after adjusting the offset of a camera in order to overlay a plurality of images which have been planarized by said planarization unit; a comparison-processing unit for determining whether or not corresponding pixels are identical in the comparison area selected by said comparison-area selecting unit, and generating a single image based on the results of the determination; and an object-detecting unit for detecting a three-dimensional object disposed on the ground by analyzing the form of the single image generated by said comparison-processing unit.
