A terminal for generating an augmented reality, the terminal comprising:

• a sensor configured to detect a position or a direction associated with the terminal;
• a camera unit configured to output an image;
• a terminal posture estimator configured to estimate a posture of the terminal based on the position and the direction associated with the terminal detected by the sensor;
• a virtual object composition unit configured to compose a virtual object and the image input by the camera unit;
• and
• a controller configured to determine whether camera property information is stored when generating an augmented reality is requested, to request camera property information of the terminal from a camera property information providing server when the camera property information is not stored, and to compose the virtual object and the image based on the camera property information and the estimated posture when the requested camera property information is received.
