摘要： The current document is directed to methods and systems for guiding a wand for scanning one or more surfaces of a three-dimensional, solid object, in particular, within the oral cavity of a patient, as well as for providing semi-automated and automated training to technicians who use oral-cavity-imaging-and-modeling systems to accurately and efficiently generate three-dimensional models of patients' teeth and underlying tissues. The methods and systems are implemented either as subsystems within oral-cavity-imaging-and-modeling systems or as separate system in electronic communication oral-cavity-imaging-and- modeling systems. The methods and systems use an already generated, digital, three- dimensional model of a portion of the oral cavity of a particular patient or of a physical model of a portion of an oral cavity to compute a temporal, translational, and rotational trajectory of an oral-cavity-imaging-and-modeling endoscope, or wand, during a training scan.

摘要： 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.
