Abstract

The invention relates to a calibration method and calibration device based on a cross-shaped reference device, belongs to the technical field of measurement, and solves a problem that a measurement point is not liable to be measured when the measurement point is an inward concave point in the prior art. The invention provides a calibration method based on a cross-shaped reference device. The calibration method comprises the steps of: 1, a measuring piece A and a measuring piece B are manufactured respectively; 2, designing a cross-shaped reference device; 3, respectively installing a cross-shaped reference device on the measuring piece A and the measuring piece B; 4, enabling the component A and the component B to be in butt joint; 5, calculating the relative distance between the measuring point A and the measuring point B; and 6, checking the component A and the component B. According to the invention, extraction and re-measurement of the recessed point are realized, the measurement process is simple and convenient, and the measurement precision is high.

Description

technical field [0001] The invention relates to the technical field of measurement, in particular to a calibration method and a calibration device based on a cross-shaped fiducial. Background technique [0002] Accurate large-scale docking of the aircraft is an important process link to ensure the overall structural dimensions of the aircraft, and it is also a prerequisite for subsequent sub-system assembly work. During the docking process of large parts, the relevant characteristic dimensions must be guaranteed. The docking of large parts often involves the dimensional accuracy of multiple sets of cross-link points, and the characteristics of each set of cross-link points are distributed on different parts, resulting in a spatial characteristic relationship between each cross-link point and multiple cross-link points located in different parts. [0003] By using the laser tracker to measure the information position of the fixed reference point arranged in the measurement si...
