“…(2002), Yau H. T. (1997), andNarayanan Namboothiri V. N., Shunmugam, M. S., (1998) describe different data accuracy and error analysis methods, such as, linear approximation techniques, least-square method, and geometric and surface shape evaluation. Cheng, J.T., Zhao, W. L., Xie, X. D., (2009) made an improvement of the method of data quality assessment, while Wu, X. M. does an error analysis and precision evaluation of reconstructed surfaces in which the accuracy of a CMM machine is evaluated (Wu, X. M., Yu, G. B., Li, G. X., Shan, D. B., 2011). The above computerized/automated system resolves the limitations of the manual systems including time consuming and human error.…”
