Abstract
An apparatus for estimating distance according to the present disclosure extracts feature maps from respective images including a reference image and a source image; projects a source feature map extracted from the source image onto hypothetical planes to generate a cost volume; sets sampling points on a ray extending from the viewpoint of the reference image in a direction corresponding to a target pixel in the reference image; interpolates features of the respective sampling points, using features associated with nearby coordinates; inputs the features corresponding to the respective sampling points into a classifier to calculate occupancy probabilities corresponding to the respective sampling points; and adds up products of the occupancy probabilities of the respective sampling points and the distances from the viewpoint of the reference image to the corresponding sampling points to estimate the distance from the viewpoint of the reference image to a surface of the object.
