1. A device for estimating a depth map using multi-view images, comprising:

  • a multi-view image storing unit that stores the multi-view images input through a multi-view video camera;

    a segment setting unit that sets a segment for pixels having a difference in the intensity between adjacent pixels is equal to or less than a threshold value in a target image where the depth map is to be estimated among the multi-view images stored in the multi-view image storing unit;

    a three-dimensional warping unit that acquires a warped image by performing three-dimensional warping for the segment set through the segment setting unit in a view of a reference image adjacent to the target image; and

    an initial depth value searching unit that estimate only one depth value for each segment at the time of estimating the depth value of the warped target image on the basis of the reference image.
