Challenges of 3D Surface Reconstruction in Capsule Endoscopy

There are currently many challenges specific to three-dimensional (3D) surface reconstruction using capsule endoscopy (CE) images. There are also challenges specific to viewing the content of CE reconstructed 3D surfaces for bowel disease diagnosis purposes. In this preliminary work, the author focuses on the latter and discusses the effects such challenges have on the content of reconstructed 3D surfaces from CE images. Discussions are divided into two parts. The first part focuses on the comparison of the content of 3D surfaces reconstructed using both preprocessed and non-preprocessed CE images. The second part focuses on the comparison of the content of 3D surfaces viewed at the same azimuth angles and different elevation angles of the line of sight. Experiments-based conclusion suggests 3D printing as a solution to the line of sight and 2D screen visual restrictions.
