Paper Abstract

Our objective is to develop a 3D endoscopic system which can be used to evaluate physical characteristics, such as perimeter and depth of objects. We describe here our dual-channel endoscopic system which relies on the structured light (SL) technology to project structured light and generate feature points on the imaged object for the measurement of surface profile. Using a modified pin-hole camera model the imaging and projection channels of the endoscope were calibrated and the distortions of both channels were corrected. Analysis of the imaged object gives the 3D surface points after establishing correspondence and triangulation. We report on the initial performance of this system on objects of known geometries. The results demonstrate the potential of the technology in clinical applications.
