1. A method for providing anatomical distance measurements during an endoscopic procedure, comprising:
placing first markings on a distal end of an elongate tool, the first markings extending longitudinally along the tool and configured to be viewable in an imaging field of view of an endoscope;
extending the elongate tool through the endoscope until the first markings are viewable in the imaging field of view;
displaying one or more captured camera images of a surgical site on at least one display device, the one or more captured camera images including an image of the elongate tool;
overlaying virtual markings onto the one or more captured camera images, the virtual markings including reference lines spaced apart at known intervals from one another and extending longitudinally along the image of the elongate tool in the displayed one or more captured camera images; and
measuring anatomical distances based on the first markings and the overlaid virtual markings.
