Abstract: A system and method for virtually inspecting a blade stage is disclosed. The system may include a digitizing device for obtaining a three-dimensional model of a shroud of each blade of the blade stage. A computer system may include at least one module configured to perform the following processes: extract a geometric location data of a plurality of reference points of each shroud from a three-dimensional model of a shroud of each blade of the blade stage created by digitizing using a digitizing device; generate a 3D virtual rendering of the shrouds of the blade stage based on the geometric location data and the known dimensions of the blade stage, the three-dimensional virtual rendering including a rendering of the plurality of reference points of each shroud; and inspect the blade stage using the three-dimensional virtual rendering.
