RESUMO:

The 3D reconstruction process follows a well-defined pipeline to generate a model that represents the geometry and appearance of an object captured using 3D scanners or other acquisition devices. The main steps of the commonplace 3D reconstruction pipeline are: a) acquisition of depth and color images of the object, b) alignment of the views acquired from different angles, c) integration of the acquired information into a single model, and d) synthesis and visualization of a textured 3D model. The models generated by following these steps are used in many areas where it is necessary to reconstruct real objects with nontrivial geometry such as engineering, architecture and museology. The present work focuses on the usage of low-cost 3D reconstruction to preserve cultural heritage artifacts, this is important not only for preservation purposes, but also as a means to study and transmit the values and traditions of the communities. In this context, we surveyed the literature for limitations of low-cost 3D reconstruction pipelines, and subsequently proposed pipeline specializations to leverage the characteristics of low-cost 3D acquisition devices and circumvent their limitations. The resulting reconstruction pipeline improved the quality of the data acquired using low-cost 3D scanners, streamlined some of the remaining following phases of the reconstruction process, and employed realism techniques to improve the appearance of the reconstructions. Several heritage artifacts from the Federal University of Bahia Museum of Archaeology and Ethnology were reconstructed using proposed approach, which yielded good results in terms of visual appearance. Thus, we conclude that low-cost 3D preservation of heritage is viable given a proper combination of pipeline specializations and realism techniques.
