A registration device for the registration of facial topographic parameters is disclosed. The device comprises a base member, wherein the base member comprises a transverse section. The transverse section, in a central section thereof, comprises a coupling for rotationally immobile coupling to a referencing member. The base member further comprises two occlusal plane indicators extending in a posterior direction from the transverse section and is rotationally immobile connected to the transverse section. The occlusal plane indicators extend in a common plane. Two mandibular condyle indicator pointers are linked to the base member in a mobile linkage relationship allowing displacement of each mandibular condyle indicator pointer relative to the base member in a respective sagittal plane. A tragus indicator is pivotably coupled to each mandibular condyle indicator pointer. A method for using said device is further disclosed.

An apparatus for measuring a deformation distribution of an object having a longitudinal dimension comprises a structure for supporting the object. A sensor unit comprises a base, a contact member having a body connected to the base by a rotational joint such rotational degrees of freedom are provided between the base and the contact member, an end of the body configured to contact and move along the object, and at least one sensor for determining an orientation of the body relative to the base. A displacement module enables relative movement between the sensor unit and the structure for the sensor unit to relatively move along the object in the longitudinal dimension. A method and system for measuring a rigidity distribution of an object having a longitudinal dimension are also provided.

A projector can be configured to project a pattern into a camera's field of view. A structural setting can be configured to receive an object in a predetermined position in the field of view. A sensor can be configured to detect that the object is in the predetermined position. A processor can be configured to, in response to the sensor detecting that the object is in the predetermined position, enable operation of the camera. The camera can be configured to obtain one or more images including the pattern on first and second surfaces of the structural setting, and the pattern on the object while the object is in the predetermined position. The processor can be configured to determine dimensions of the object based upon positional information for the first and second surface of the structural setting.

A robot arm supporting a workpiece, a support mechanism in a form of a coordinate measuring machine supporting a detector head, and a fixation portion in a form of a contact block fixing the detector head to the workpiece are used to bring the contact block fixed to a table and the workpiece into contact to each other.
