1. A three-dimensional data encoding method of encoding three-dimensional points, the three-dimensional encoding method comprising:
encoding first coordinate information indicating coordinates where the three-dimensional points exist in a first coordinate system;
encoding a first conversion parameter for converting the first coordinate information to second coordinate information indicating coordinates where the three-dimensional points exist in a second coordinate system;
encoding a second conversion parameter for converting the second coordinate information to third coordinate information indicating coordinates where the three-dimensional points exist in a third coordinate system; and
generating an encoded bitstream including the first coordinate information, the first conversion parameter and the second conversion parameter.
