Abstract
A data processing apparatus includes input interface circuitry to which first three-dimensional data and second three-dimensional data indicating objects acquired at timings different from each other for a same person are input, and processing circuitry configured to compare pieces of soft tissue of at least one tooth between the first three-dimensional data and the second three-dimensional data using a shape of a crown portion of the at least one tooth included in the objects as a reference and output comparison information regarding a comparison result.
Claims18
A data processing apparatus that processes three-dimensional data of objects inside an oral cavity, the data processing apparatus comprising:
- input interface circuitry to which first three-dimensional data and second three-dimensional data indicating including position information of each point of a point cloud representing surfaces of at least one tooth and gums around the at least one tooth included in the objects acquired at timings different from each other for a same person are input;
- and
- processing circuitry configured to compare the gums around the at least one tooth between the first three-dimensional data and the second three-dimensional data using a shape of a crown portion of the at least one tooth included as a reference and output comparison information regarding a comparison result,
- wherein the processing is circuitry configured to compare each point of a point cloud comprising the gums around the at least one tooth indicated by the first three-dimensional data with each point of a point cloud comprising the gums around the at least one tooth indicated by the second three-dimensional data.
A data processing method for processing three-dimensional data of objects inside an oral cavity by a computer, the data processing method comprising:
- acquiring, by processing circuitry of the computer, first three-dimensional data and second three-dimensional data including position information of each point of a point cloud representing surfaces of at least one tooth and gums around the at least one tooth included in the objects acquired at timings different from each other for a same person;
- comparing, by the processing circuitry of the computer, the gums around the at least one tooth between the first three-dimensional data and the second three-dimensional data using a shape of a crown portion of the at least one tooth included in as a reference;
- and
- outputting, by the processing circuitry of the computer, comparison information regarding a comparison result,
- wherein the data processing method further comprises comparing each point of a point cloud comprising the gums around the at least one tooth indicated by the first three-dimensional data with each point of a point cloud comprising the gums around the at least one tooth indicated by the second three-dimensional data.
A data processing system that processes three-dimensional data of objects inside an oral cavity, the data processing system comprising:
- a three-dimensional scanner that acquires the three-dimensional data of the objects;
- and
- a data processing apparatus that processes the three-dimensional data acquired by the three-dimensional scanner,
- wherein the data processing apparatus comprises:
- input interface circuitry to which first three-dimensional data and second three-dimensional data indicating including position information of each point of a point cloud representing surfaces of at least one tooth and gums around the at least one tooth included in the objects acquired at timings different from each other for a same person are input;
- and
- processing circuitry configured to compare the gums around the at least one tooth between the first three-dimensional data and the second three-dimensional data using a shape of a crown portion of the at least one tooth included as a reference and output comparison information regarding a comparison result,
- wherein the processing circuitry is configured to compare each point of a point cloud comprising the gums around the at least one tooth indicated by the first three-dimensional data with each point of a point cloud comprising the gums around the at least one tooth indicated by the second three-dimensional data.
