Abstract
A three-dimensional data encoding method includes: obtaining a data unit including three-dimensional points; encoding the three-dimensional points included in the data unit; and generating a bitstream including encoded data obtained by encoding the data unit. In the encoding: a first determination for determining whether to continuously use a context to encode the data unit is made, the context being used in encoding a previous data unit preceding the data unit; and the data unit is encoded using a context according to a result of the first determination. In the first determination, when the data unit is a lead data unit in a random access unit, it is determined not to continuously use the context used in encoding the previous data unit.
