1. A method of constructing a three-dimensional (3D) model of an object, the method comprising:

  • capturing images of the object by scanning the object along a trajectory around the object;

    estimating positions of a scanner, which respectively correspond to the captured images;

    identifying an accumulated drift of position and orientation of the scanner based on at least two locations on the trajectory;

    re-estimating the positions of the scanner by distributing the accumulated drift among the positions;

    generating a surface mesh of the object by using the re-estimated positions of the scanner; and

    constructing and displaying the 3D model of the object by using the generated surface mesh,wherein the re-estimating of the positions further comprises;

    identifying for each of key frames a variance indicating to what extent position is corrupted by measurement noise and the accumulated drift,providing key frames having a high position variance with stronger position correction, andproviding key frames having a low position variance with less position correction.
