A new data fusion method for scanned models

This paper introduces a high- and low-resolution data integration method for scanning systems. The high-resolution data captured by a touch probe on a CMM, in the form of geometric features, and the low-resolution laser scanned model, in the form of triangulated mesh, are sent to a CAD software. The two model types are first integrated into a unique coordinate system and then unified into a precise CAD model. Depending on the part complexity, some or all of the modelling process can be done automatically. This data fusion method enhances the flexibility of scanning while maintaining the accuracy of the results.
