Research on Aircraft Digital Shape Measurement Data Fusion Method

摘要

In this paper, the uncertainty model of laser radar and Metrascan detection is established, combined with the the accessibility of laser radar in the actual measurement, the accuracy of the measured network is simulated and analyzed, and a digital measurement method, which combines the advantages of two advanced measurement techniques, Metrascan and laser radar, is proposed. This method of netted measurement for different digital equipment, uses a high precision laser radar coordinate system as the reference transformation coordinate system, improves the measurement precision of large-size measurement of Metrascan, thus, which realizes the high precision and high efficiency measurement for the digitization of the aircraft shape.
