Abstract: A three dimensional scanning apparatus is used to detect a contour of an object, and includes an illumination light source, a first elliptic opening portion, a reference pattern generator, a second elliptic opening portion and an optical receiver. The illumination light source emits an illumination beam. The reference pattern generator provides a reference pattern by projection of the illumination beam, and transmits the reference pattern toward the object via the first elliptic opening portion. The optical receiver receives a detection pattern reflected from the object via the second elliptic opening portion, so as to analyze a difference between the reference pattern and the detection pattern for acquiring the contour.

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 three dimensional scan system includes a projection device, an image capturing module and an image formation device. The projection device includes a lighting module for providing a light beam, and a pattern generator for receiving the light beam and project a predetermined pattern. The image capturing module is used to capture images. The image formation device is used to form a projected pattern by projecting the predetermined pattern onto an object, and to project an image of the object and the projected pattern to the image capturing module. An optimal image formation focal plane of the image formation device for forming the predetermined pattern is different from an optimal image capturing focal plane of the image formation device for projecting the projected pattern.

Abstract: A three-dimensional contour scanning device including an image sensing element, a light source and a single polarity element is provided. The light source is used for emitting a projection light to a to-be-scanned object through a projection optical path. The projection light reflected from the to-be-scanned object becomes an imaging light further reflected to the image sensing element through an image-formed optical path. The single polarity element is disposed on the projection optical path and the image-formed optical path.
