Full field surface data of cylindrically shaped objects, such as a human's head, can be quickly achieved by rotating a laser scanner and imaging system about the subject. B-spline surfaces can then be fitted to the measurements for data reduction and compatibility with NURBS based CAD systems. Techniques available for surface fit are subject to user input. Parameters, such as, the number of control points, tension (in the sense of a thin plate spline), etc. must be chosen to achieve optimal fit. This paper will discuss optimal choice of surface fitting parameters for human head scan data. Techniques for determining these optimal parameters, should be a benefit to other researchers with specifically shaped data sets.
