PURPOSE: An object detecting device using a 3D image and a method thereof are provided to shorten object detection time by detecting an object according to a size change of the object by using distance information of the object. CONSTITUTION: An image processing unit(120) generates an image pyramid about a 2D image of an object obtained from an image obtaining unit(110), divides a 3D image obtained from the image obtaining unit into one or more object candidate areas by using distance information, and estimates an object size of each object candidate area. An object detecting unit(130) selects a 2D image level corresponding to the object size from the image pyramid and detects the object from the 2D image included in the level by using a detection mask. [Reference numerals] (111) 2D image obtaining unit; (112) 3D image obtaining unit; (121) Image pyramid generating unit; (122) Area dividing unit; (123) Object size estimating unit; (131) Image level selecting unit; (132) Object extracting unit |
