Achsenkreuz für photogrammetrische Kameras.
Die Fäden des Fadenkreuznetzes photogrammetrischer Apparate sind Schwingungen unterworfen, wenn der Apparat an einem Fahrzeug, z. B. einem Flugzeuge, angebracht ist, so dass das Netz sich nicht mit genügender Schärfe auf die lichtempfindliche Schicht abzeichnet. Um nun eine möglichst scharfe Abbildung des Achsenkreuzes zu erzielen, besteht es nach der Erfindung aus hochkant zur Bildebene gestellten Metallstreifen.
Die Zeichnung zeigt ein Austührungsbeispie ! des Ernndungsgegenstandes durch Fig. 1
EMI1.1
von hinten.
In das hintere Ende der Dunkelkammer 1 der photographischen Kamera, deren optische Achse mit x bezeichnet ist. ist ein aus zur Bildebene hochkant gestellten Metallstreifen gebildetes Achsenkreuz' ? eingesetzt, dessen Schnittpunkt in der optischen Achse x gelegen ist.
Das Bild des starren Achsenkreuzes zeichnet sich auf der lichtempfindlichen Schicht scharf ab und ermöglicht somit vollständig sichere Abmessungen.
EMI1.2
Das Achsenkreuz kann auch an einem in den \pparat schiebharen Rahmen angebracht sein.

Axis for photogrammetric cameras.
The threads of the crosshair network of photogrammetric apparatus are subject to vibrations when the apparatus is attached to a vehicle, e.g. B. an aircraft is attached, so that the network does not stand out with sufficient sharpness on the light-sensitive layer. In order to achieve the sharpest possible image of the axis cross, according to the invention it consists of metal strips placed on edge to the image plane.
The drawing shows an Ausührungsbeispie! of the subject of the invention by Fig. 1
EMI1.1
from behind.
In the rear end of the darkroom 1 of the photographic camera, the optical axis of which is denoted by x. is an axillary formed from metal strips placed on edge to the picture plane '? used whose intersection is located in the optical axis x.
The image of the rigid axbox is sharply defined on the light-sensitive layer and thus enables completely reliable dimensions.
EMI1.2
The ax cross can also be attached to a frame that can be pushed into the \ pparat.
