Abstract:
This paper proposed a shape recovery approach from Endoscope Image using Eikonal Equation. Photometric constraint equation derived from the Lambert reflectance and geometrical constraint equation derived from the relationship between the neighboring points are used and these equations can make a new approximation equation of Eikonal equation under the point light source illumination and perspective projection. The original endoscope image is transformed and generated to the Lambertian image by removing the specular reflectance. Framework of Fast Marching Method using the derived Eikonal Equation can recover the 3D shape from endoscope image. Usefulness was confirmed using simulation and experiments.
