Abstract

Patients suffer from emotional pain as well as physical hurt due to body or skin deformation caused by e.g. laceration, burns, amputation, e.g. the removal of the whole breast as the result of cancer diagnosis. Many operations in plastic surgery, such as face or breast reconstruction, base on intensive preoperative planning. 3D models can help in preoperative planning. Currently, our medical partner uses a 3D laser scanner to obtain a 3D model. Such laser scanners provide depth information from one view. To get a full model of the patient, views from different directions have to be taken. This information has to be combined afterwards, which is a time consuming task. The goal of this project is to automate the registration of several partially overlapping 3D scans. This problem is similar to the well known image stitching to generate panorama photos or Ultrasound Mosaicing.

This images shows the depth information of a human head obtained with a laser scanner. In this project multiple such images of the human torso, taken from different directions, have to be automatically registered.
