Dynamic measuring object angle measuring instrument and measuring method

Abstract

The invention provides a dynamic object-to-be-measured angle measuring instrument and a measuring method. The measuring instrument includes a reference inertial navigation system, a small-angle measurement system and a dynamic inertial navigation system; the reference inertial navigation system is installed on the object to be measured and is used for feedback The position information of the object to be measured; the small-angle measurement system and the dynamic inertial navigation system are set together, and the relative positions of the two remain unchanged, forming the measurement part A; the dynamic inertial navigation system is used to obtain the position information of the measurement part A, and the small-angle measurement system is used for Obtain the angle information of the object to be measured; the coordinate system centers of the reference inertial navigation system, the small-angle measurement system and the dynamic inertial navigation system coincide, and the coordinate systems of the three are under the equipment coordinate system. The technical solution provided by the present invention can realize the angle measurement when the object to be tested and the carrying platform move synchronously, and can be operated by a single person without the need for multiple people to cooperate in the measurement.

Description

technical field [0001] The invention relates to the field of angle measurement, in particular to a dynamic object-to-be-measured angle measuring instrument and a measuring method. Background technique [0002] At present, angle measurement is an important part of metrology science, which is widely used in industrial production. The angle between the center line and the normal line of the plate). Such requirements involve spatial angle measurements at larger spacings. Traditional angle measurement methods such as CMM method, multi-station theodolite method, collimator method, etc. have certain limitations in measurement accuracy and application range, and all require the object to be measured to maintain a static and stable state. The existing method for testing the angle between a large-sized object (over 10 meters) and additional equipment is the vertical target method. This method is a manual measurement method. The entire measurement process takes more than a few hours ...

Problems solved by technology

The existing method for testing the angle between a large-sized object to be measured (more than 10 meters in size) and additional equipment is the vertical target method. This method is a manual measurement method. The entire measurement process takes more than several hours and requires more than ten meters. It can only be completed with the assistance of multiple people at the same time. The operation is complicated, the efficiency is low, the requirements for the environment are high, and it is impossible to measure the dynamic measured object.

[0003] Existing technologies and equipment require the measured object to be measured in an absolutely stable environment. If it is aimed at a dynamic measured object or on a carrying platform, it cannot be tested, which greatly limits the application range of angle measurement and cannot be obtained in many fields. High-precision angle measurement data; and cannot perform real-time measurement efficiently, greatly reducing the timeliness of data collection
