Optical scan data including a first set of images representing a first portion of a three-dimensional object is received. A processing device receives ultrasound scan data including a second set of three-dimensional images representing a second portion of the three-dimensional object. The processing device performs image stitching between the second set of three-dimensional images using the optical scan data. The processing device then creates a virtual model of the three-dimensional object based on the stitched second set of three-dimensional images. The images may in particular be intraoral images. Further, an intraoral scanner is described, which comprises an optical imaging device and an ultrasound imaging device at a fixed relative position. An inertial measurement device may be provided to determine the probe orientation. |
