8 Claims

1. A three-dimensional data decoding method comprising:

obtaining three-dimensional space information including encoded three-dimensional points;

calculating an angle formed by a line segment connecting a predetermined position in the three-dimensional space information and a first base point and a line segment connecting the first base point and a second base point different from the first base point;

determining whether the angle calculated satisfies a predetermined condition; and

decoding the encoded three-dimensional points included in the three-dimensional space information when the angle is determined to satisfy the predetermined condition, and not decoding the encoded three-dimensional points included in the three-dimensional space information when the angle is determined not to satisfy the predetermined condition.
