This method generates a three-dimensional object by sensing the roughness of the object and acquiring multiple 3D coordinate data, then converting the acquired point cloud data into polygon data, which is a collection of triangular surfaces. AeroEdge uses a 3D scanner device equipped with a high-precision digital camera to capture 3D data of the object with the best combination for any scan measurement. Using non-contact scanning technology with fringe patterns, complex surface structures can be acquired with high accuracy, and the measurement results, including CAD data comparison, can be projected onto the actual object in full color for visualization and reverse engineering of the measurement results.
