A portion of an object in the field of view is illuminated with a structured light pattern, and light reflected from the field of view is detected. From the reflected light, a 3D image of the field of view is constructed, and 3D locations of points on a surface of the object are determined. The real time 3D spatial position of the endoscope and/or a surgical tool is determined. If a distance between the surface the endoscope and/or surgical tool, as determined using the 3D spatial position, falls below a predetermined distance, an alert is generated to notify a user."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Articulated structured light based-laparoscope","description":"In a method of using a structured-light based system, real-time 2D images of a portion of a field of view are captured using an endoscope.
