1. A depth imaging device comprising:

  • a light source to emit light corresponding to a predetermined pattern;

    an imaging sensor to receive the light reflected by the environment of the depth imaging device and that, when in operation, generates a depth map including a plurality of pixel values corresponding to depths of the environment relative to the imaging device; and

    a processor that, when in operation, estimates a shift of the pattern by using a polynomial model depending on the temperature drift of the light source and adjusts the depth map based on the shift of the pattern.
