Modelling cloud data for prototype manufacturing

Contour curve reconstruction from cloud data for rapid prototyping

“…Liu et al [11] introduced a simple and computationally efficient point-based curve model, the intermediate point-based curve model (IPCM). In this method, first the point cloud data reduced by a method similar to digital image technology.…”

“…A contour extraction method directly from the cloud data is given in literature [11]. In this method, discrete curvatures and a local interpolating method was used to compress data points.…”

Integrating cross-sectional imaging based reverse engineering with rapid prototyping

“…Upon completion of this procedure, the minimum number of contours that represents the shape of the measured object is determined, and the slices that are needed for fabrication are generated from these data. In Liu's research [12], a layer-based RP model is directly extracted from the cloud data through slicing, projecting, compressing and intersecting. However, this method can only handle cloud data that has no holes and lobes.…”

Shape reconstruction, shape manipulation, and direct generation of input data from point clouds for rapid prototyping

“…Some researchers have employed a direct slicing strategy for point clouds. [8][9][10][11] In these methods, the sectional contours are extracted directly from the point clouds under the assumption that the points are distributed evenly enough for uniform space partitioning. However, if there are too many holes in the raw point cloud data and the distribution of points is not uniform, such techniques cannot be used for direct slicing.…”
