3D printing using digital photogrammetric data

摘要

The research is mainly focus on modeling of non-topographic objects based on Photogrammetry field of studies. By using 3D printing technology that is widely used nowadays, a real object could be reproduced again exactly as it is through post processing of object model formed by RGB-D camera and printing out of the post-processed file using 3D printer. In this project, a cylinder box and half part of human body are chosen for the printing purpose to represent simple and complex object respectively. Reconstruct me software was used to scan the object while the Meshmixer software was applied in the post-processing of the formed models. Distances of 0.8m, 1.0m and 1.5m were selected to scan both objects and the scanned model was saved in Stereolithography (STL) file format. Then, the formed models was uploaded in Meshmixer to filter unnecessary features like noise and unfilled holes. The cleaned model was also saved in STL file format to enable it to be uploaded in XYZ Ware software before it can be printed in da Vinci 1.0 3D printer. From this study, it was found that the methodology used can be produced the exact model of the chosen objects in three-dimensional copies with the reduced scale. In term of analysis, the studies show that the time acquired to form the 3D model increases significantly between non-complex and complex object. In conclusion, the concept of 3D printing is much related to the field of Photogrammetry especially in generating the 3D model because it involve the use of image photos, triangulation network and contouring of the object models.
