ENDOSCOPIC MEASUREMENT SYSTEM AND METHOD

摘要

The invention is a system and method for measuring 3D distances and dimensions of objects in endoscopic images by using a light plane to make Euclidean and geodesic measurements. The endoscopic measurement system of the invention comprises a flexible or rigid endoscopic device equipped with standard visualization means and a module containing components for generating a light plane. Based on triangulation, the intersection curve between the light lane and the object of interest is measureable in 3D in the coordinate system of the visualization means.

主权项

1. A system for measuring 3D distances and dimensions of objects that are visible in endoscopic images, the system comprising:
a) a flexible or rigid endoscopic device comprising visualization means; b) a conventional endoscopy system adapted to operate the endoscopic device and to obtain and display images gathered by the visualization means; c) a light plane generating module comprising a light source and optical elements configured to generate a light plane; and d) a processing station comprising: processing means, dedicated software modules adapted for making both Euclidian and geodesic measurements, a graphical user interface (GUI), software, a pointing device, and a display adapted to present to the user of the system images acquired by the visualization means overlaid with graphics and text.
