Decoding method, encoding method, and decoding device

Abstract

A decoding method is a decoding method for decoding encoded three-dimensional points each having position information including a distance component, a first direction component, and a second direction component, and includes: determining at least one method out of an entropy decoding method or a debinarization method for information on a first encoded three-dimensional point, according to a total number of second three-dimensional points each having a first direction component and a second direction component that are respectively and substantially equal to a first direction component and a second direction component of the first encoded three-dimensional point, the first encoded three-dimensional point being included among the encoded three-dimensional points, the second three-dimensional points being included among decoded three-dimensional points; and performing processing that uses the at least one method determined.
