A self-calibration rotational stitching method for precision measurement of revolving surfaces (2018)
Journal Article
Liu, M., Cheung, C., Feng, X., Wang, C., & Leach, R. (in press). A self-calibration rotational stitching method for precision measurement of revolving surfaces. Precision Engineering, https://doi.org/10.1016/j.precisioneng.2018.05.002

When measuring revolving objects, it is often desired to obtain not only the geometrical form of the workpiece, but also the topography of the surface, as they both affect the performance of the part. However, holistic measurement of the entire three... Read More about A self-calibration rotational stitching method for precision measurement of revolving surfaces.

Hierarchical-information-based characterization of multiscale structured surfaces (2018)
