In Reverse Engineering (RE), Point Cloud Data (PCD) processing is of great importance. But at present, a number of key issues about its algorithms are unresolved. This article mainly introduces the author who has done the research and put forward some specific algorithms on the aspects of data topology reconstruction, multi-view data registration and data reduction, and then developed a PCD processing system --3DPointshop, based on OpenGL and MFC. Through a series of instances of tests show that the prototype system which contains the algorithms and function modules will be able to implement on PCD processing well and could achieve the practical application level.

National handcrafts are well-known at home and Abroad for their fine ingredients, exquisite blending of colors, and excellent skilled shaping and painting. What is more, they have great value and are deeply popular with people around the world. National handcrafts, as a cultural crystallization, must be protected. In order to better realize the protection, we try to apply the technology of reverse engineering to the protection. This article mainly takes a handcraft, Yan Zi YU (meaning “swallow fish”), as an example to expound and demonstrate the process of reverse engineering technology. During this process, by using scanning technology of reverse engineering, the collection and splicing of the point cloud data, the theoretical analysis of the NURBS surface in the reconstruction phase, and other practical operations in other stages, reverse engineering can be used to regenerate 3D modal data of the swallow fish and to inspect and analyse the errors in it through Geomagic Quality to ensure that the new model meets the precision requirements. Therefore, the reverse engineering technology can be completely applied to the protection of national handcrafts so that they can fully demonstrate their own value and function. If the precision of reverse engineering detection can reach nanometric level, a breakthrough will promote the protection of cultural relics.

The Face

This paper analyzes the techniques that can be used to perform point cloud data registration for a human face. We found that there is a limitation in full scale viewing on the input data taken from 3D camera which is only represented the front face of a man as the point of view of a camera. This has caused a hole on the surface that is not filled with the point cloud data. This research is done by mapping the retrieved point cloud to the surface of the face template of the human head. By using Coherent Point Drift (CPD) algorithm which is one of the non-rigid registration techniques, the analysis has been done and it shows that the mapping of points for a three-dimensional (3D) face is not done properly where there are some surfaces work well and certain points spread into the wrong area. Consequently, it has resulted in registration failure occurrences due to the concentration of the points which is focusing on the face only.

Cloud Data Processing

In reverse engineering, data pre-processing has played an increasingly important role for rebuilding the original 3D model. However, it is usually complex, time-consuming, and difficult to realize, as there are huge amounts of redundant 3D data existed in the gained point cloud. To find a solution for this issue, point cloud data processing and streamlining technologies are reviewed firstly. Secondly, a novel pre-processing approach is proposed in three steps: point cloud registration, regional 3D triangular mesh construction and point cloud filtering. And then, the projected hexagonal area and the closest projected point are defined. At last, a parabolic antenna model is employed as a case study. After pre-processing, the number of points are decreased from 4,066,282 to 449,806 under the constraint of triangular grid size h equaling to 2mm, i.e. about 1/9 size of the original point cloud. The result demonstrates its feasibility and efficiency.

This paper analyzes the structure of molding tool for composite component, and proposes a method of surface design of molding tool based on reverse engineering. By using handy laser scanner, the point cloud data is obtained from the composite component, which is processed in Geomagic Studio. Then the processed data is imported into CATIA for Surface fitting. The surface of molding tool for composite component is rapidly and accurately designed by analyzing 3D error and comparing cross-sectional data.
