METHOD AND APPARATUS FOR RECOGNIZING THREE DIMENSIONAL OBJECT

摘要

The present invention relates to a three dimensional object recognizing method and a device thereof. In the example of the present invention, a terminal includes a display unit which displays the operation state of the terminal and a recording unit which receives images. The three dimensional object recognizing method of the terminal includes a first input step for receiving a first image as an input by setting the brightness of the display unit as a first brightness; a second input step for receiving a second image as an input by setting the brightness of the display unit as a second brightness; and a recognizing step for comparing the first image and the second image and recognizing a three dimensional object based on the brightness changes in the predetermined area. Given in the example of the present invention, a three dimensional object recognizing method and a device thereof capable of preventing a security function from malfunctioning using two dimensional images are provided. [Reference numerals] (305) Receive a lock release command;(310) Photograph a third image by setting the brightness of the display unit as a third brightness;(315) Photograph a fourth image by setting the brightness of the display unit as a fourth brightness;(320) Is a first image same with the third image?;(325) Determine as recognition failure;(330) Recognize an object depending on brightness difference by comparing the third image and the fourth image for an extracted area in the 220 step;(AA) Start;(BB) No;(CC) Yes;(DD) End
