A novel method for intra-operative data acquisition using a laser range scanner is presented for applications in model-updated image-guided surgery. The scanner produces a point cloud containing true-color encoded range data of its field-of-view. This allows characterization of intra-operative conditions using both intensity and geometry information. Furthermore, a rigid-body registration algor...
