Essential for improving the accuracy and reliability of bowel cancer screening, three-dimensional (3D) surface reconstruction using capsule endoscopy (CE) images remains challenging due to CE hardware and software limitations. This study focuses on 3D visualization challenges and briefly investigates the impact of indeterminate selection of the line-of-sight on 3D surfaces reconstructed using both preprocessed and non-preprocessed CE images. Furthermore, the study examines the content of 3D surfaces viewed at the same azimuth angles and different elevation angles of the line of sight. The study concludes that 3D printing of reconstructed 3D surfaces can overcome the challenges such as 2D screen line-of-sight indeterminate selection and visual restrictions.
