Abstract
A three-dimensional model generation method includes: generating a first three-dimensional model of a predetermined region from first frames; projecting the first three-dimensional model onto at least one second frame; and generating a second three-dimensional model in accordance with first pixels in the at least one second frame onto which the first three-dimensional model is not projected.

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.
A three-dimensional model generation device comprising:
- memory;
- and
- a processor coupled to the memory and configured to:
- generate a first three-dimensional model of a predetermined region from first frames from among a plurality of frames;
- project the first three-dimensional model onto projection pixels at least one second frame from among the plurality of frames, the at least one second frame being different from the first frames;
- locate, in the at least one second frame, first pixels onto which the first three-dimensional model is not projected;
- and
- generate a second three-dimensional model in accordance with only the first pixels.
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;
- determining whether at least one second position from which the at least one second frame is captured is nearer to the predetermined region than any one of first positions from which the respective first frames are captured;
- and
- when the at least one second position is determined to be nearer to the predetermined region than any one of the first positions, updating the first three-dimensional model in accordance with the projection pixels before the updated first three-dimensional model is projected;
- and
- generating a second three-dimensional model in accordance with only the first pixels in the at least one second frame onto which the first three-dimensional model is not projected. outputting the first three dimensional model and the second three dimensional model.
