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 recursiveprocedure and calculating the optimum number of control points. The reconstruction precision is evaluated through Ja-cobi’s transformation method. The feasibility of the measurement system and effectiveness of the reconstruction algorithm above are proved by experiment.
