Abstract
The process device for the photogrammetrical measurement of the human head, especially of the middle region of the face with the eye sockets, the nose, the check bones and the brows, is comprised of a projector for projecting a pattern image onto the face and two cameras which can simultaneously take two pictures from two different directions of the face and head with the pattern image projected on it. The two cameras and the projector are supported by an apparatus carrier, which can be moved in a vertical direction relative to a base permanently connected to the device and in at least one horizontal direction. This minimum of one direction coincides with the optical axes of the cameras. The device will facilitate bringing both the projector and the cameras on the one hand and the human head on the other into the required relative position to one another as necessary to take the pictures.
