We propose a local model called moving multiple curves/surfaces approximation to separate mixed scanning points received from a thin-wall object, where data from two sides of the object may be mixed due to measurement error. The cases of two curves (including plane curves and space curves) and two surfaces in one model are mainly elaborated, and a lot of examples are tested.
