US 2018/0293747 A1 · METHOD AND APPARATUS FOR DETERMINING A GEOMETRIC MEASUREMENT VARIABLE OF AN OBJECT

Abstract

A site measuring device (4) for determining a geometric measurement variable of an object (1) based on a three-dimensional model (11) which is stored in a model memory (13) and has a gravity vector (g). The site measuring device (4) has a marking unit (14) that marks a first feature (P0) and a second feature (P1) in the model (11) and a fitting unit (15) that determines a first auxiliary geometry (L0), which contains at least the first marked point feature (P0) and extends parallel to the gravity vector (g), and determines a second auxiliary geometry (E1), which contains at least the second marked feature (P1) and extends perpendicular to the gravity vector (g) and for forming the point of intersection (P2) of the auxiliary geometries (L0, E1). A calculation unit (17) calculates the geometric measurement variable with the aid of the point of intersection (P2).
