Abstract:
Based on the development of the non-contact measurement system
of free-form surface, NURBS reconstruction of measurement points
of freeform surface is effectively realized by modifying the
objective function and recursive procedure and calculating the
optimum number of control points. The reconstruction precision
is evaluated through Jacobi’s transformation method. The
feasibility of the measurement system and effectiveness of the
reconstruction algorithm above are proved by experiment.
