Stereoscopic liver surface reconstruction
The paper presents a practical approach to measuring liver motion, both respiratory and laparoscopic, with a tool guided in the operating room. The presented method is based on standard operating room equipment, i.e. rigid laparoscopic cameras and a single incision laparoscopic surgery trocar. The triangulation algorithm is used and stereo correspondence points are marked manually by two indepe...
متن کاملIn vitro evaluation of stereoscopic liver surface reconstruction
INTRODUCTION Tracking abdominal motion of organs is an important factor in image-guided navigation systems. The paper presents the evaluation methodology of a practical approach to measure liver motion, both respiratory and laparoscopic, with a tool guided in the operating room. AIM Evaluation of the methodology of a practical approach to measure liver motion, both respiratory and laparoscopi...
متن کامل3D Surface Reconstruction from Stereoscopic Image Sequences
A stereoscopic scene analysis system for 3–D modeling of objects from stereoscopic image sequences is described. A dense map of 3–D surface points is obtained by image correspondence, object segmentation, interpolation, and triangulation. Emphasis is put on the accurate measurement of image correspondences from grey level images. The surface geometry of each scene object is approximated by a tr...
متن کاملStereoscopic Surface Perception
Physiological, computational, and psychophysical studies of stereopsis have assumed that the perceived surface structure of binocularly viewed images is primarily specified by the pattern of binocular disparities in the two eyes' views. A novel set of stereoscopic phenomena are reported that demonstrate the insufficiency of this view. It is shown that the visual system computes the contrast rel...
متن کامل3-D Stereoscopic Reconstruction using Structured Light
0. Abstract Much like humans, computers are able to infer 3-D positions of objects using sight alone. Replacing our eyes with electronic cameras and our brain with soulless , heartless algorithms, it is possible for a computer to reconstruct a 3-D scene from simple photos. In order to understand the relative positions of objects in the world, we can take two photos of the same scene (from diffe...
