Abstract:
3D objects mapping is an important field of computer vision, being applied in games, tracking, and virtual and
augmented reality applications. Several techniques implement 3D reconstruction from images obtained by
mobile cameras. However, there are situations where it is not possible or convenient to move the acquisition
device around the target object, such as when using laptop cameras. Moreover, some techniques do not achieve
a good 3D reconstruction when capturing with a stationary camera due to movement differences between
the target object and its background. This work proposes two 3D object mapping pipelines from stationary
camera images based on COLMAP to solve this type of problem. For that, we modify two background
segmentation techniques and motion recognition algorithms to detect foreground without manual intervention
or prior knowledge of the target object. Both proposed pipelines were tested with a dataset obtained by a
laptop’s simple low-resolution stationary
RGB camera. The results were evaluated concerning background
segmentation and 3D reconstruction of the target object. As a result, the proposed techniques achieve 3D
reconstruction results superior to COLMAP, especially in environments with cluttered backgrounds.
