Embodiment Construction

[0024] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0025] The technical solution proposed by the present invention is an improvement on the basis of the technical solution disclosed in the patent with application number 201910994110.7. In the technical solution disclosed in the patent application number 201910994110.7, the reflective surface assembly is used instead of the plane reflector, and the recognition method is used to distinguish the reflected light from the plane reflective surface and the reflected light from the right-angle reflective surface, and the target to be measured is calculated by analyzing the reflected light from the plane reflective surface The pitch angle and azimuth angle of the target are calculated by analyzing the reflected light of the right-angle reflective surface to calculate the roll angle of the target to be measured, so as to realize the measurement of the three-dimension...

Abstract

The invention discloses a three-dimensional attitude measurement method. The method remarkably improves the measurement precision of a light spot slope through constructing a virtual single-dimensional high-resolution imaging element, achieves the high-precision measurement of a roll angle, and enables one measurement process to achieve the second-level three-dimensional high-precision attitude measurement at the same time.

Description

technical field [0001] The invention belongs to the field of optical technology, and in particular relates to a three-dimensional attitude measurement method. Background technique [0002] A photoelectric autocollimator is an instrument that uses the principle of self-collimation of light to measure small angles. In the prior art, when measuring the attitude of the target to be measured, the photoelectric autocollimator can be used to effectively realize the second-level precision measurement of the two-dimensional angle of azimuth and pitch. Regarding roll angle measurement, patents such as Publication No. CN1335483A have proposed a polarization phase method measurement scheme, but none of the above methods can realize high-precision three-dimensional attitude measurement at the same time. In the existing technology, some technologies have proposed a three-dimensional attitude measurement method based on an autocollimator. In this method, the measurement of azimuth and pit...
