1. A three-dimensional model generation method comprising:
generating a first three-dimensional model of a predetermined region from first frames from among a plurality of frames;
projecting the first three-dimensional model onto projection pixels in at least one second frame from among the plurality of frames, the at least one second frame being different from the first frames;
locating, in the at least one second frame, first pixels onto which the first three-dimensional model is not projected; and
generating a second three-dimensional model in accordance with only the first pixels.
