Abstract
The present invention provides a structured-light based system for providing a 3D image of at least one object within a field of view within a body cavity, comprising: a. An endoscope; b. at least one camera located in the endoscope's proximal end, configured to real-time provide at least one 2D image of at least a portion of said field of view by means of said at least one lens; c. a light source, configured to real-time illuminate at least a portion of said at least one object within at least a portion of said field of view with at least one time and space varying predetermined light pattern; and, d. a sensor configured to detect light reflected from said field of view; e. a computer program which, when executed by data processing apparatus, is configured to generate a 3D image of said field of view.
