摘要
PURPOSE: A method for measuring depth and an apparatus thereof are provided to measure the depth by using a stereo method, thereby detecting more corresponding points in comparison with a feature-based method. CONSTITUTION: An attribute-based searching member(24) obtains a corresponding point in the second image on the basis of an attention point in the first image. A depth calculating member(26) calculates a depth value relating to the attention point by applying the principle of triangulation. A depth interpolating member(30) interpolates depth values of plural attention points having determined depth values, and then calculates depth values of the attention points having no corresponding points. A provisional corresponding point acquisition member(32) determines provisional corresponding points of the attention points having no corresponding points from the calculated depth values. A corresponding point recalculating member(34) performs a regional-based searching limited adjacent to the provisional corresponding points so that more exact corresponding points than the provisional corresponding points can be obtained.
