Abstract

Device comprises two or three measurement arms, hinged so that they can be moved relative to each other. Displacement of the arms is determined by electronic measurement of the angular displacement of the arms relative to each other and the measured angular displacement is converted, using a computer, to a diameter measurement.

Description

Bezeichnung der ErfindungName of the invention Meßgerät zur GeometriebestimmungMeasuring device for geometry determination Kurzfassungshort version Technisches Problem der ErfindungTechnical problem of the invention

Die Geometrie von Körpern, insbesondere des Stammquerschnitts Bäumen, wird zur Zeit durch die Messung von zwei um 90° versetzten Strecken, der sogenannte Kreuzkluppung, approximiert. Dabei verwendete Meßgeräte arbeiten nach dem Meßschieberprinzip. Der technische Aufwand zur elektronischen Messung der Strecke ist beim Meßschieberprinzip relativ hoch.The geometry of bodies, especially the trunk cross-section of trees, is currently determined by the Measurement of two distances offset by 90 °, the so-called cross coupling, approximates. The measuring devices used work according to the caliper principle. The technical effort for electronic measurement of the distance is relatively high with the caliper principle.

Das neue Meßgerät soll eine technisch einfach realisierbare Variante zur mobilen rechnergestützten Messung von Entfernungen und Bestimmung von Querschnitten darstellen.The new measuring device is intended to be a technically easy to implement variant for mobile computer-aided Display measurement of distances and determination of cross sections.

Lösung des Problemsthe solution of the problem

Die Spitzen von durch Gelenken miteinander verbundenen Schenkeln werden an das Meßobjekt gehalten. Über die Messung des Winkels im Drehpunkt kann der Abstand der Schenkelspitzen ermittelt werden. Aus mehreren so bestimmten Entfernungen kann der Querschnitt des Körpers, insbesondere des Baumstammes, ermittelt werden. (Siehe Skizze.)The tips of legs connected by joints are attached to the object to be measured held. The distance between the tips of the legs can be measured by measuring the angle at the pivot point be determined. The cross-section of the body, especially the tree trunk. (See sketch.)
