Area of Science:

  • Minimally Invasive Surgery
  • Surgical Imaging
  • Computer Vision

Background:

  • Laparoscopic surgery faces challenges with limited depth perception and field of view (FOV).
  • These limitations can hinder surgeon's ability to accurately perceive the operative space.

Purpose of the Study:

  • To improve surgeon's perception and spatial awareness during laparoscopic procedures.
  • To enhance the visible operating space and depth perception using advanced imaging techniques.

Main Methods:

  • Utilizing dual-camera units for stereoscopic vision.
  • Employing epipolar geometry estimation for accurate 3D scene mapping.
  • Implementing image processing algorithms to augment visual feedback.

Main Results:
