  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 report generally focuses on challenges associated with 3D
visualization and specifically investigates the impact of the indeterminate
selection of the angle of the line of sight on 3D surfaces. Furthermore, it
demonstrates that impact through 3D surfaces viewed at the same azimuth angles
and different elevation angles of the line of sight. The report concludes that
3D printing of reconstructed 3D surfaces can potentially overcome line of sight
indeterminate selection and 2D screen visual restriction-related errors.
