Suchada Rianmora, Naiwen Chang

Abstract


By knowing the significant factors and controlling in scanning-surface acquisition, the alternative method has been introduced and it will be able to reduce the surface reconstruction time by 20–30% while controlling the 3D CAD model quality that will benefit greatly in surface fitting and rapid prototyping process. The working environment (light intensity) and other important factors (object sizes, reference gap, surface coating, and the number of images for non-scanning method as well as degree of capturing) were studied in this research for supporting the design phase of developed equipment called Mini C-Arm Rotary Camera Station (RCS). The tips for adjusting camera conditions on the RCS are presented to avoid the errors occurred during surface acquisition. The obtained results could be applied for assisting the 3D laser scanner to capture small details of the object’s surfaces. The design and components of this developed equipment are the key components which need to be identified and analyzed for obtaining the good 3D model.
