Title:
METHOD FOR 3D-RECONSTRUCTION OF IMAGES ACQUIRED BY MEANS OF LASER RADAR, AND ENDOSCOPIC APPARATUS USING SUCH METHOD
Document Type and Number:
WIPO Patent Application WO2005008283
Kind Code:
B1
Abstract:
The invention refers to a method for 3D-reconstruction of, particularly endoscopic, images having: aim direction of a scanning signal, distance between the scanning head and detected point, intensity 1 of the signal reflected by the point, and characterised in that it comprises the following steps: A, subdividing the set of points detected along time in a plurality of sub-sets ordered in time; B, for each sub-set, calculating a reference surface approximating the same, and a reference system, and projecting the sub-set points onto such surface; C, for each sub-set, determining zone of overlap with one or more preceding sub-sets, on the basis of the comparison of the intensities 1 for a plurality of points; D, positioning the reference surfaces so that the overlap zones coincide; E, returning to the coordinates of the detected points of each sub-set with respect to its own reference system. The invention further concerns an endoscopic apparatus using the method according to the invention.
