Vorrichtung zur plastischen Wiedergabe von Objekten nach photogrammetrischen
Messbildern.
Das Patent Nr. 60833 bezieht sich auf eine Vorrichtung zur plastischen Wiedergabe von Objekten nach zwei in einer gemeinsamen Ebene liegenden stereoskopischen Messphotogrammen. Vorliegende Erfindung bezweckt die Anwendung der Vorrichtung auf in verschiedenen Ebenen liegende photogrammetrische Messbilder. Die Fig. 1 zeigt beispielsweise und schematisch eine Ausführungsform im Grundriss, während Fig. 2 die Grundfläche 5 mit der auf ihr angeordneten Einrichtung in Seitenansicht zeigt.
Die Messbilder 2 und 3a (Fig. 1) sind in einem den Aufnahmen entsprechenden Winkel angeordnet, mittels der um die Punkte 7 und 7a drehbaren Grundflächen 5 und 5a und sind in ihren Bildebenen horizontal und vertikal verschiebbar mittels der Schlittenführungen 8 und 10 (Fig. 2), während die optischen Beobachtungsinstrumente 4 und 4a auf den Grundflächen feststehen, z. B. 4 auf 5 (Fig. 2). Die Messbilder sind vermittelst der beiden Lager 11 und lia zwangläufig mit zwei um die beiden Drebungslager 7 und Va schwenkbaren Richtungslinienträgern 9 und 9'verbunden, deren Richtungslinien z. D. durch die mittleren Längsachsen von in ihrer Längsrichtung verschiebbaren Punktierstiften bzw. durch Visierstrahlen oder Lichtstrahlen gebildet werden können.
Werden nun zwei korrespondierende Bildpunkte. durch Verschiebung der Platten in die optischen Achsen der Beobachtungsinstrumente eingestellt, so schwenken die Richtungslinienträger gleichzeitig automatisch im Raum, z. B. in die Stellungen 9a oder 9b und der Schnittpunkt ihrer Licht- oder Visierstrahlen bezeichnet den gesuchten Raumpunkt P der plastischen Nachbildung 21.

anstatt mit den Messbildern zwangläufig verbinden ; in diesem Falle bleiben letztere feststehen, während die RiehtungsHnienträger parallel zu den Plattenebenen bewegt werden.
Rekonstruktionen in verändertem Massstabe werden ausgeführt, indem man den Abstand B zwischen den beiden Drehungslagern 7 und 7a nach Massgabe der gewünschten Vergrösserung oder Verkleinerung ändert. Hiezu kann man sich beliebiger bekannter Vorrichtungen bedienen. Beispielsweise ist in der Fig. 1 ein Grundträger 1 mit zwei Schlitten 6 und 6a gezeichnet, welcher eine Miilimeterteilung trägt zwecks Regulierung des Abstandes der beiden Drehungspunkte 7 und a voneinander.

Device for the plastic reproduction of objects according to photogrammetric
Measurement images.
The patent No. 60833 relates to a device for the plastic reproduction of objects according to two stereoscopic measurement photograms lying in a common plane. The present invention aims to apply the device to photogrammetric measurement images lying in different planes. FIG. 1 shows, for example and schematically, an embodiment in plan, while FIG. 2 shows the base 5 with the device arranged on it in a side view.
The measurement images 2 and 3a (Fig. 1) are arranged at an angle corresponding to the recordings, by means of the base surfaces 5 and 5a rotatable about the points 7 and 7a and are horizontally and vertically displaceable in their image planes by means of the slide guides 8 and 10 (Fig. 2), while the optical observation instruments 4 and 4a are fixed on the base, e.g. B. 4 to 5 (Fig. 2). By means of the two bearings 11 and lia, the measurement images are inevitably connected to two directional line carriers 9 and 9 ′ which can be pivoted about the two rotary bearings 7 and Va. D. can be formed by the central longitudinal axes of puncturing pins displaceable in their longitudinal direction or by sighting rays or light rays.
There are now two corresponding pixels. set by moving the plates in the optical axes of the observation instruments, the directional support automatically pivot in space at the same time, e.g. B. in the positions 9a or 9b and the intersection of their light or sighting rays denotes the spatial point P of the plastic replica 21 sought.

instead of necessarily connecting with the measurement images; in this case the latter remain stationary while the directional hinge supports are moved parallel to the plane of the plates.
Reconstructions on a different scale are carried out by changing the distance B between the two rotary bearings 7 and 7a according to the desired enlargement or reduction. Any known devices can be used for this purpose. For example, FIG. 1 shows a base support 1 with two carriages 6 and 6a, which carries a millimeter graduation for the purpose of regulating the distance between the two pivot points 7 and a from one another.
