METHOD AND DEVICE FOR CREATING AT LEAST ONE SECTION OF A VIRTUAL 3D MODEL OF A BODY CAVITY

摘要

The invention relates to a method for creating at least one section of a virtual 3D model of a body cavity (12), in particular a hollow organ, from data, which is made available by at least one endoscope (16) that is introduced into the body cavity (12). The data includes at least one position and orientation of the endoscope (16), whereby said position(s) and orientation(s) are associated with at least one distance between the endoscope (16) and at least one point (42) of a surface (14) of the body cavity (12) and with at least one endoscopy image of the surface (14) of the body cavity (12) in the vicinity of the point or points (42) on the surface (14) of the body cavity (12). The section(s) of the 3D model is/are created from the data for several different positions and orientations of the endoscope (16) with a superposition of the relevant endoscopy image. The invention also relates to a corresponding device.
