Abstract

There are currently many challenges related to three-dimensional (3D) surface reconstruction using capsule endoscopy (CE) images. There are also challenges related to viewing the content of reconstructed 3D surfaces. In this preliminary investigation, the author focuses on the latter and evaluates their effects on the content of reconstructed 3D surfaces using CE images. The evaluation of such challenges is preliminarily conducted 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. The experiments demonstrated the need for generalizable line-of-sight and advanced CE image preprocessing means as well as further research in 3D surface reconstruction.
