Background Blurring and Removal for 3D Modelling of Cultural Heritage Objects

Cultural heritage, such as relics, is a heritage of historical and artistic values created through wisdom and human work in a society that needs to be preserved. These objects are important for humanity because they contain historical stories and should be maintained well. Therefore, digitizing cultural heritage is crucial for modern people to maintain and recover the missing part through 3d modeling and provide access to the public. In this paper, we study the effect of background blurring and removal for 3d modeling of cultural heritage, followed by an automatic method for blurring and removing the background. Background blurring and removal are essential to improve the camera pose estimation in Structure from Motion (SfM), as the image matching will focus on the desired object. SfM algorithm is applied to images captured by a camera with the photogrammetry technique. The camera captures the image of objects from different views, and the images are processed with the SfM algorithm to obtain the 3d reconstruction. We hope that this work could bring a great benefit to digitizing and preserving cultural heritage objects.
