Space vector object three-dimensional rotational coordinate measuring method

Abstract

The invention discloses a space vector object three-dimensional rotational coordinate measuring method. The space vector object three-dimensional rotational coordinate measuring method comprises the following steps of: 1) mounting a laser on a measured vector object, placing a reflecting prism at one side of the measured vector object, placing a lens at the other side of the measured vector object, and placing photoelectric probing arrays behind the lens; 2) when the measured vector object is not changed, storing image points on a first photoelectric probing array into a computer; 3) when a rotation angle of the measure vector object is changed, causing light rays to be reflected onto a second photoelectric probing array as an incidence position of laser light on a reflecting prism is changed; 4) transmitting the acquired data into the computer by the photoelectric probing array to obtain two image point coordinates; and 5) analyzing and calculating by virtue of the computer to obtain information of a three-dimensional rotation angle of the vector object, and then controlling a numerical control rotary table to rotate the measured vector object to the original position by virtue of a singlechip. A measuring device used in the space vector object three-dimensional rotational coordinate measuring method has the advantages that structure is reasonable and simple, anti-jamming performance is strong and a small angle variation of the measured space vector object can be timely and accurately determined.

Description

technical field [0001] The invention relates to a high-precision measurement and application technology of a space vector, in particular to a technology for achieving high-precision position measurement and deviation correction through the joint action of a precise measurement system and a deviation correction system. Background technique [0002] With regard to complex environments, such as the measurement of space vectors under various climatic conditions and sports environments, countries all over the world have invested a lot of manpower and material resources in research, but there has been no particularly efficient and practical equipment. Traditional space measurement mainly includes: laser interferometer method; laser three-dimensional scanning method; laser speckle method, etc. Among them, although the laser interferometer method has high precision, it has poor environmental adaptability, and the measurement accuracy is directly affected by the environment; the lase...
