1. A camera tracking apparatus comprising:

  • a reconstruction segment generation unit to generate, using a processor, three-dimensional space reconstruction segments for a reconstruction process from an image including depth information obtained by a camera, the reconstruction segments including first and second reconstruction segments;

    a transformation matrix generation unit to generate, using a processor, a transformation matrix for the first reconstruction segment having a distortion among the generated reconstruction segments during the reconstruction process; and

    a reconstruction segment connection unit to rotate or move, or rotate and move, using a processor, the first reconstruction segment according to the transformation matrix, and to connect the rotated or moved, or the rotated and moved first reconstruction segment with the second reconstruction segment having substantially no distortion,wherein the reconstruction segment generation unit generates a corresponding one of the reconstruction segments based on a timing when a movement factor of the camera is greater than a preset value.
