In reverse technology, the key step in front of importing model is the data preprocessing. The purpose of de-nosing is to remove the needless curved surface on the three-dimension (3-D) model by scanning. The stereo lithography (STL) data obtained by three-dimensional scanning will be leaded into MATLAB by writing a program, and then a triangular grid pattern can be got. Using the improved subdivision wavelet, the reconstitution and de-noising of the multi-resolution grid can be completed. To import the three-dimensional figure data into SolidWorks, and a better surface is constituted. In comparison with and research the new graph with the previous that has noise and the model after Geomagic Studio, this method has a better effect.

In this paper, the master-slave synchronization of chaotic Lur'e systems is presented by means of quantization measurement of synchronization errors. The quantizer adopted takes finitely many values, which possess a common adjustable time-varying parameter. By using the adaptive laws for the time-varying parameter, and estimating boundary error values of quantization, a new adaptive quantized state controller design method with the quantized state measurements is proposed for chaotic Lur'e systems. Finally, numerical example is given to demonstrate the effectiveness of the proposed the method.
