Method and apparatus for recognizing three-dimensional object

摘要

Provided are a method and an apparatus for recognizing a three-dimension object using a light source. The method of recognizing a three-dimension object of a terminal including a display unit for displaying an operation state of the terminal and a shoot unit for receiving an image, includes: receiving a first image by setting first brightness as brightness of the display unit; receiving a second image by setting second brightness as the brightness of the display unit; and recognizing the three-dimension object based on brightness change of a preset part by comparing the second image with the first image. The apparatus and method for recognizing a three-dimension object prevents a security function from being incapacitated using a two-dimension photograph.
