<p>This invention relates to a method of making stereophotographic documentation and photogrammetric measurement of impressions or of models of jaws. The method is characterized by the combination of the following moments: the impression or the model of a jaw is placed on a reference object (13), which in its turn is placed on a bottom plate (3) in a photo device comprising a camera (1) mounted in a frame (2) at a distance from the bottom plate and a light source (11) for illuminating the object on the reference object; a picture of the impression or the model of a jaw is taken by means of the camera (1), when this one has taken a position at an angle distance from the vertical line, whereafter a second picture is taken of the impression or the model of a jaw when the camera (1) has taken the corresponding position on the other side of the vertical line; the two pictures (19, 20) are placed on a tray (21) which is intended to cooperate with a stereoscope in that way that the two pictures can be seen three-dimensionally in the stereoscope; the pictures (19, 20) are brought to cooperate with a dator, which is so programmed that three-dimensional coordinates for picture points can be determined, which makes determination of desired distances and angles possible. The invention also relates to an apparatus which is usable for carrying out the method.</p> |
