    摘要: Disclosed is an incision foil made of a sterile, thin adhesive plastic film with a defined pattern printed on it (e.g. a fine grid pattern) which can be stuck e.g. on a patient's skin surface and which marks the anatomical region of interest. Using a camera, images are acquired of the attached film and the deformation of the pattern is digitized. With a computer vision algorithm the surface of the patient, which corresponds to the surface of the film, is reconstructed from the detected pattern features in the images in comparison to the known original undeformed pattern. Disclosed is also a method for determining a geometry of the surface of the patient using the incision foil.
