Computer aided process as 3D data provider in footwear industry

Abstract

One of the new emerging of ubiquitous manufacturing is Mass Customization. The combination of 3D scanning systems with mathematical technique makes possible the development of CAD system which can help the selection of good footwear for a given customer. During the surface reconstruction process, a mesh is calculated from points cloud. This mesh may have holes corresponding to deficiencies in the original point data. Although these data are given in an arbitrary position and orientation in 3D space. Moreover, there is a need to mesh segmentation in order to shape retrieval form shoe last data base. Thus to apply sophisticated modeling operation on data set, substantial preprocessing is usually required. In this paper first, we describe an algorithm for filling hole. Then all of the models are aligned and at the end the models are segmented in order to use for further analysis.
