Abstract: A cap mountable on and detachable front an intraoral scanner including a housing having an opening for connecting to at least a part of the intraoral scanner, a measurement window provided in the housing and located opposite to the opening, and a mirror that reflects light from the measurement window toward the opening. The housing has a longitudinal length shorter than that of a probe defining a depth-of-field, of the intraoral scanner extending from the measurement window to a predetermined extent.

Abstract: 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.

Abstract: The present disclosure provides a three-dimensional scanner for acquiring three-dimensional shape information of an object using focusing, including a light source configured to emit light from an emission end face of a housing to the object; a sensor configured to detect light from the light source reflected by the object; a variable focus lens that is provided between the object and the sensor and that changes a focal position based on the object; and a controller configured to change the focal position of the variable focus lens in a process of acquiring the three-dimensional shape information of the object, wherein the controller is configured to change an amount of light from the light source reflected by the object and reaching the sensor based on the focal position of the variable focus lens.

Abstract: 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.
