1. A three-dimensional data encoding method, comprising:
encoding first point cloud data obtained by a plurality of sensors to generate encoded data; and
generating a bitstream including the encoded data,
wherein for each of three-dimensional points included in the first point cloud data, the first point cloud data includes (i) geometry information indicating a three-dimensional position of the three-dimensional point and (ii) one or more items of attribute information of the three-dimensional point,
wherein the bitstream includes first information includes configuration information indicating the plurality of sensors from which the first point cloud data is obtained,
wherein the first information includes items of second information respectively generated for the three-dimensional points included in the first point cloud data so that each of the items of second information corresponds one-to-one with each of the three-dimensional points included in the first point cloud data,
wherein each of the items of second information indicates (i) the three-dimensional point corresponding to the item of second information, (ii) the geometry information indicating the three-dimensional position of the three-dimensional point corresponding to the item of second information, (iii) the one or more items of attribute information of the three-dimensional point corresponding to the item of second information, and (iv) a sensor, among the plurality of sensors indicated in the first information, from which data corresponding to the three-dimensional point is obtained, and
wherein when the first point cloud data is divided into one of more items of second point cloud data, the first point cloud data is divided according to the items of second information.
