摘要：
According to some embodiments of the present invention, a system for stereo reconstruction from a monoscopic endoscope is provided. The monoscopic endoscope comprising an image pick-up element at a distal end thereof and a working channel defined by a body of the monoscopic endoscope. The working channel provides a port at the distal end of the monoscopic endoscope. The system for stereo reconstruction comprises a light patterning component configured to be disposed within the working channel of the monoscopic endoscope such that a light emitting end of the light patterning component will be fixed with a defined relative distance from the distal end of the image pick-up element. The system for stereo reconstruction also includes a data processor adapted to be in communication with the image pick-up element. The light patterning component forms a pattern of light that is projected onto a region of interest. The data processor is configured to receive an image signal of the region of interest that includes the pattern, and determine a distance from the endoscope to the region of interest based on the image signal and based on the defined relative distance between the light emitting end of the light patterning component and the distal end of the image pick-up element.
