Deformation amount and servo angle detection method for large precision industrial equipment

Abstract

The invention discloses a deformation amount and servo angle detection method for large precision industrial equipment, and belongs to the technical field comprising industrial measurement and geodetic measurement. The invention uses a technology combining an industrial photogrammetry system, a laser tracker and a high precision total station. The invention mainly comprises the contents of the following aspects: (1) on the basis of a reference ruler, the lengths of two line segments measured by a laser tracker are also used as a length reference of the photogrammetry, and spatial scale accuracy of the photogrammetry can be improved while a mutual check can be performed; (2)the measuring camera can shoot any position of a target at any angle by a self-made shooting assist telescopic rod, thereby solving an observation problem of large equipment; (3)the high precision conversion of a photogrammetry coordinate system to a geodetic coordinate system is realized by using a local gravity horizontal coordinate system established by the laser tracker as a transition.

Description

technical field [0001] The invention belongs to the intersecting technical field of industrial surveying and geodetic surveying, and in particular relates to a detection method for deformation amount and servo angle of large-scale precision industrial equipment. Background technique [0002] Problems with existing measurement methods: The result is an independent photogrammetric coordinate system, which lacks a high-precision conversion method with the national geodetic coordinate system; Restricted by factors such as the depth of field of industrial measurement cameras and the reflection angle of photographic signs, it is easy to produce blind spots when shooting large equipment; The length ratio of large-scale equipment to the scale is too large, which is not conducive to the overall spatial scale precision control. The unit undertook the deformation amount and servo angle detection project of a large-scale precision industrial equipment in Xinjiang. In order to overc...
