The invention concerns a rigid videoscopic apparatus (1) spatially located and comprising a triangulation laser profilometer for computer-assisted surgery. A laser beam coplanar with the videoscope (1) optical axis is spread out in a line (7). The deformation of the line viewed by the videoscope camera enables to know the distance of the points illuminated by the laser line relative to the videoscope. The videoscope being positioned by sensors (10, 11) in the preoperative scanner imaging, the position of the points illuminated by the laser line (7) is known both in the preoperative scanner imaging and in the video imaging. Said real-time image blending enables to produce a first image registration of the medical imaging with the video images (contactless matching), and to enhance the video image with the data of the scanner (augmented reality), and to update the scanner by the result of the surgical resection through the data derived from the videoscope (surgically modified imagery). |
