Data processing apparatus and data processing method

A data processing method for processing three-dimensional data, the data processing method comprising:

• receiving at least first data and second data, the first data being obtained by performing scanning by a scanner that is inserted inside a mouth of a target person and including coordinate data of a point group indicating a surface shape of a tooth row including a first crown and gingiva, the second data being obtained by capturing at least the tooth row inside the mouth of the target person by an X-ray imaging device and including volume data of a second crown;
• and
• converting the first data and the second data into a common data format, and synthesizing the first data and the second data after conversion with each other, wherein
• the synthesizing the first data and the second data includes, in relation to the second data,
• replacing the second crown included in the second data, with which a shape of the first crown matches, with the first crown included in the first data, and
• performing synthesis in such a way that the gingiva is arranged near the first crown after replacement.

A non-transitory computer-readable storage medium for storing computer-readable instructions that, when executed by a computer, cause the computer to perform a method, the method comprising:

• receiving at least first data and second data, the first data being obtained by performing scanning by a scanner that is inserted inside a mouth of a target person and including coordinate data of a point group indicating a surface shape of a tooth row including a first crown and gingiva, the second data being obtained by capturing at least the tooth row inside the mouth of the target person by an X-ray imaging device and including volume data of a second crown;
• and
• converting the first data and the second data into a common data format, and synthesizing the first data and the second data after conversion with each other, wherein
• the synthesizing the first data and the second data includes, in relation to the second data,
• replacing the second crown included in the second data, with which a shape of the first crown matches, with the first crown included in the first data, and
• performing synthesis in such a way that the gingiva is arranged near the first crown after replacement.
