An information processing apparatus includes management circuitry that manages three-dimensional data obtained by a scanner in the order of obtaining, display controller circuitry that controls a display to show a three-dimensional image generated from combined data generated by combining a plurality of pieces of three-dimensional data, and input circuitry that accepts an operation by a user. When the input circuitry accepts an operation to select three-dimensional data, the management circuitry sets, from the selected three-dimensional data of last obtained three-dimensional data, data to be deleted. The display controller circuitry controls the display to show a three-dimensional image modified to exclude the data to be deleted.

Information processing apparatus and data processing method for processing data obtained by a scanner positionally variable in relation to a subject

A magnifying glass captures an image of a tooth by a plurality of cameras for observation. The plurality of cameras includes a narrow range camera capturing a narrow range image of the tooth and a wide range camera capturing a wide range image of the tooth. The magnifying glass includes a three-dimensional position calculator detecting a three-dimensional position of at least the tooth based on the wide range image; a blur correction processor correcting a blur of the narrow range image, based on a change in a three-dimensional positional relationship between the tooth, the three-dimensional position of which has been detected by the three-dimensional position detector, and the narrow range camera; and an image display portion displaying at least the narrow range image having the blur corrected.

Observation device, observation unit, and observation method

An intraoral three-dimensional measuring method, comprising: acquiring, with a handy scanner, wide range three-dimensional measurement information on a three-dimensional shape measured on a wide range in a desirable measurement range in an intraoral space; acquiring, with the handy scanner, a plurality of pieces of narrow range three-dimensional measurement information each on a three-dimensional shape measured on a narrow range narrower than the wide range in the measurement range; and locating, with a controller, the plurality of pieces of narrow range three-dimensional measurement information based on the wide range three-dimensional measurement information by use of, as a synthesis reference, intra-measurement range position information common to the wide range three-dimensional measurement information and each of the plurality of pieces of narrow range three-dimensional measurement information, and creating synthetic three-dimensional information on the measurement range.

Intraoral three-dimensional measuring device, intraoral three-dimensional measuring method, and intraoral three-dimensional measurement result display method

An OCT measuring mechanism for acquiring the optical coherence tomography information and a surface shape measuring mechanism for acquiring the three-dimensional shape information share a display device, a control device, a light source, a scanning mirror, a light transmission/receiving path and an entering/exiting opening. The scanning mirror, the light transmission/receiving path, the entering/exiting opening are included in a handpiece operable to make a diagnosis on a diagnostic target site.
