“…This prediction capability was used to develop adaptive inspection methods for engineering problems and was successfully implemented in surface metrology to design adaptive sampling strategies for machined parts on CMMs (Ascione et al, 2013; Du and Fei, 2016). The Kriging model has also been used to identify the minimum number of checkpoints to reduce measurement errors (Dumas et al, 2013) and estimate the uncertainty to improve measurement accuracy (Fei et al, 2019). In the inspection of an unknown freeform surface, a few initial points are sampled manually (Zhang et al, 2021) or by other means (Chen and Peng, 2017; Lu et al, 2019; Sun et al, 2017b).…”
