3D laser scanning point cloud data is the basis of free-form surface modeling technique. This paper focuses on the preprocessing of the original point cloud data. Techniques including denoising step using wavelet transform, data reduction and mending using Image ware are discussed in details. Surface reconstruction is finally achieved to demonstrate that the proposed data preprocessing methods improve the easy realization of point cloud data with higher accuracy and faster speed, and thus take
