摘要：
-20- Abstract The invention concerns a method for the spatial mapping of a model of a surgical tool onto a spatial location of the surgical tool. The method comprises the following steps: a) providing a 5 surgical tool having a working part and a marker in the form of a visual image on a surface, such as a bitmap image, the marker being arranged at a pre-determined marker location fixed relative to the working part of the surgical tool； b) providing a tool model of the surgical tool, the tool model comprising at least the working part of the surgical tool and its location relative to the marker； c) providing a viewing device configured to be carried by a user and comprising a 10 camera configured to capture a view and to generate camera data representative of the view； d) creating a spatial model of a space viewed by the camera； e) bringing the surgical tool within the space viewed by the camera； f) identifying a representation of the marker in the camera data； g) determining a position and rotation of the representation of the marker with respect to the spatial model, and h) creating a spatial mapping of the tool model in the spatial model, the 15 creation of the spatial mapping being based on the tool model and the determined position and rotation of the marker.
