Method and apparatus for representing a work area in a three-dimensional structure
First Claim
1. A method for representing a work area in a three-dimensional structure, comprising the steps of:
- providing an image of said work area via a viewing device;
determining the position of said viewing device or an instrument movable therewith relative to said structure;
comparing the determined position of said viewing device or instrument to a set of coordinates of a predetermined path of displacement therefor in said structure; and
representing said predetermined path of displacement in said image as a piercing point through respective observed planes of said structure to enable said viewing device or instrument to be guided generally along said predetermined path.

Abstract
In order to ensure, in a process for representing a work area in a three-dimensional structure in which the work area is imaged by a viewing device, that the viewing device or an instrument can be introduced into the structure along a predetermined path of displacement despite the different positioning of the viewing device, it is suggested that the relative positioning of the viewing device is determined relative to the structure, that the coordinates of a path of displacement are predetermined for an instrument or for the viewing device in the structure, are compared with the respective positioning and the path of displacement is represented in its correct position in the image. A device for performing this process is also described.

18. Apparatus for representing a work area in a three-dimensional structure comprising:
-
a viewing device for sharply imaging a plane of the work area; measuring means for determining a position of the viewing device relative to said structure; a comparator for comparing position data of said viewing device determined by said measuring means with a set of coordinates of a predetermined path of displacement along a plurality of respective planes in the work area; a display unit for displaying an image of one of said plurality of planes in said work area being observed by said viewing device; and a data memory for storing a set of data for said path of displacement relative to said structure; wherein said display unit is responsive to said set of data for providing an image of a piercing point for the plane of said work area currently being observed by said viewing device, said piercing point being shown in its correct position along said path of displacement.
