Measuring system and measuring method for large-scale plane directional variation

Abstract

The invention discloses a measuring system for large-scale plane directional variation. The measuring system for large-scale plane directional variation includes a line style laser emitter, one-dimensional PSD measuring points, a measuring controller and an information processor, wherein the information processor is in data connection with the measuring controller; the measuring controller is in control connection with the line style laser emitter; the measuring system is provided with a plurality of one-dimensional PSD measuring points, and every one-dimensional PSD measuring point is provided with a one-dimensional PSD sensor; the ray output by the line style laser emitter is transmitted to the one-dimensional PSD sensors; the one-dimensional PSD sensors are in data connection with the measuring controller; and the plurality of one-dimensional PSD measuring points are arranged on a large-scale plane. The invention also provides a measuring method for large-scale plane directional variation. The measuring method can obtain the position variation of each measuring point through coordination of the line style laser emitter with the one-dimensional PSD sensing technology, and can obtain the direction variation of the large-scale plane through solution so as to perform further adjusting or compensation of the large-scale plane.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a measurement system and method for large-scale plane pointing changes. Background technique [0002] In the field of measurement technology, measurement applications of large-scale planes are usually involved. For example, the orientation of large-scale planes changes due to deformation or vibration. It is necessary to measure the orientation changes of large-scale planes. [0003] Existing measurement methods usually have the following defects: [0004] 1. Automatic measurement cannot be realized; [0005] 2. The volume and weight of the measuring equipment are large; [0006] 3. Strict requirements for the layout of measuring equipment; [0007] Not suitable for measuring pointing changes on large flat surfaces. Contents of the invention [0008] Aiming at the above-mentioned deficiencies in the prior art, the present invention provides a measurement system and meth...
