Abstract: An calibration kit includes a base, a combination of calibration parts, and a manipulation part. The combination of calibration parts is disposed on the base and includes a first calibration part and a second calibration part. The first calibration part has a first calibration surface. The second calibration part has a second calibration surface. The first calibration part and the second calibration part are relatively movable in a movement direction and are movable relative to the base. The manipulation part is movably or rotatably disposed on the base. The manipulation part is configured to be operable to drive the first calibration part and the second calibration part to move in the movement direction relative to the base, so that the combination of calibration parts forms a three-dimensional calibration surface configuration through the first calibration surface and the second calibration surface.

Abstract: A method of controlling an intraoral scanner includes upon completion of lighting a first projection device, triggering a second projection device to initiate lighting, upon initiation of lighting the first projection device, transmitting a first camera trigger signal, a first delay circuit delaying the first camera trigger signal until completion of lighting the second projection device, and upon receiving the first camera trigger signal, a first camera and a second camera starting exposing images.
