Abstract: To match the requirement of multiscale feature coexistence and multisource measurement data fusion,based on combined measurement,a flexible inspection method for large-scale product was put forward for onsite automated inspection.According to this method,a flexible measurement unit framework was presented to make the unit realize wide-area movement,local precise execution and end high-accuracy inspection.The optimization model of flexible measurement unit was formulated to analyze the unit measurement space and its measurement uncertainties.Based on the analysis,a large-scale product flexible inspection method was researched,in which a measurement station planning algorithm based on K-means clustering and an adaptive control strategy based on measurement data were proposed.An experimental flexible inspection system was self-designed and developed.The assembly stepped difference and gap inspection was taken as an example,whose inspection results demonstrated the feasibility and validity of this technology.

Key words: combined measurement, large-scale product, flexible measurement unit, flexible inspection, assembly stepped difference and gap
