METHOD FOR GENERATING HIGH RESOLUTION DEPTH IMAGE FROM LOW RESOLUTION DEPTH IMAGE USING BILATERAL INTERPOLATION DISTANCE TRANSFORM BASED, AND MEDIUM RECORDING THE SAME

摘要

The present invention relates to a method for generating a depth map of high quality and high resolution from a low resolution depth map. The method includes the following steps of: generating an edge map by extracting an edge from the low resolution depth map; performing a distance conversion by a method for obtaining a distance from pixels except the edge to the closest edge in the edge map; performing a bilateral interpolation based on the distance conversion; and generating a high resolution depth map through a bilateral interpolation process based on the distance conversion. The method is able to generate the high resolution depth map by solving the problem of an existing bilateral interpolation method.
