Title:
GEOMETRIC QUANTITY MEASUREMENT METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/056755
Kind Code:
A1
Abstract:
A geometric quantity measurement method and device. An elastic load transfer element (103) and a load measurement assembly (102) are adopted; the load measurement assembly (102) hinders a first bearing part (1032) of the elastic load transfer element (103) from moving with respect to an inertial reference system (106); a first measurement boundary (1018) or a second measurement boundary (1019) is connected to the load measurement assembly (102) by means of the elastic load transfer element (103), such that the elastic load transfer element (103) is deformed, and generates a corresponding material internal force; a constraining force (107, 107', ...) is measured by using the load measurement assembly (102), and a function relationship between the constraining force (107, 107', ...) and a geometric quantity to be measured is obtained by means of comparison; the geometric quantity to be measured is obtained by measuring the magnitude of the constraining force (107, 107', ...), and a function relationship between the geometric quantity to be measured and a standard geometric quantity is obtained by means of comparison; and the magnitude of the geometric quantity to be measured is determined. The obtained beneficial effects are that: measurement sensitivity and measurement stability can be improved, any geometric quantity in space and any displacement of a point, line or plane can be accurately measured, and any load in the space can be accurately measured.
