Abstract: 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 an image of the tooth in a narrow image capturing range and a wide range camera capturing an image of the tooth in a wide image capturing range. 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 captured by the wide range camera; a blur correction processor correcting a blur of the narrow range image captured by the narrow range camera, 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.

Abstract: An identification device that identifies a type of a tooth includes: an input unit that receives three-dimensional data including three-dimensional position information at each of a plurality of points forming the tooth; an identification unit that identifies a type of the tooth based on the three-dimensional data received by the input unit and an estimation model including a neural network; and an output unit that outputs an identification result obtained by the identification unit. The identification unit directly inputs the three-dimensional position information included in the three-dimensional data received by the input unit to the neural network included in the estimation model.

Abstract: An imaging support device that supports imaging of teeth inside an oral cavity is provided. The imaging support device includes an input unit, an identification unit, a specification unit, and an output unit. The input unit receives a tooth image obtained by imaging the teeth inside the oral cavity. The identification unit identifies a type of a tooth based on the tooth image received by the input unit. Based on the type of the tooth identified by the identification unit, the specification unit specifies a type of a tooth as a target for imaging support. The output unit outputs information about the type of the tooth specified by the specification unit to an outside at a prescribed timing.
