Large-scale blocked space attitude combined measurement device and method and automatic object attitude adjustment method

Abstract

The invention provides a large-scale blocked space attitude combined measuring device. The large-scale blocked space attitude combined measuring device comprises a measured object, a combined measuring device and an attitude adjusting mechanism; the measured object is determined to have fixed feature points A, B and C representing the horizontal attitude of the measured object, and is connected with the attitude adjusting mechanism for jacking to form a three-point supporting state so as to realize attitude adjustment; the three attitude probes are respectively clamped on a five-degree-of-freedom adjusting platform and are respectively in contact with three fixed feature points of a measured object; the MEMS micro inertial sensor is arranged on a measured object, and the output end of the MEMS micro inertial sensor is connected to the data processing terminal through the data converter; the digital level gauge is installed right in front of a measured object, observes the three attitude probes at the same time, and outputs the horizontal height of each feature point; and the data processing terminal is used for resolving the real-time attitude of the measured object according to the data output by the sensor and the horizontal height of the feature point. According to the scheme, instrument intervisibility conditions can be changed, the problem that measured points are blocked in large-scale attitude measurement is solved, accumulated errors are reduced, and the measurement precision is improved.

Description

technical field [0001] The invention relates to the technical field of precision measurement of object attitude, in particular to a large-scale barrier space attitude combined measurement device and method, and an object attitude automatic adjustment method. Background technique [0002] With the rapid development of aerospace, shipbuilding and other industrial fields, the precision measurement technology of large-scale space objects plays an important role in the assembly, docking and quality inspection of large and complex equipment, and has been increasingly valued by researchers. At present, there are many space attitude measurement equipment, including total station, laser tracker, iGPS, etc. However, in the large-scale range of several meters to hundreds of meters, due to the characteristics of large space span and complex on-site environment, there are still many problems in space attitude measurement. problem. Among them, due to factors such as the large size and co...

Problems solved by technology

One is to use multiple transfer stations of a single device to measure to avoid feature point occlusion, and to realize object attitude measurement through the unified coordinate system of the common reference point. Station will form a large cumulative error, so its application is limited

The second is to carry out multi-station collaborative measurement through multiple identical or different devices, and solve the object attitude through data fusion to improve the measurement accuracy and environmental adaptability of the system, such as the coordinated measurement of laser tracker and coordinate measuring arm or optical scanner, iGPS Measurement network construction, etc., but its technical cost is high, and measurement accuracy is greatly affected by the number of equipment and station layout methods
