TRAINING METHOD AND SYSTEM FOR ORAL-CAVITY-IMAGING-AND-MODELING EQUIPMENT

摘要

The current document is directed to methods and systems that provide 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 training 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 training 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. The temporal, translational, and rotational trajectory is used for a variety of different types of instruction and instructional feedback to facilitate training of technicians.

主权项

1. An automated training system that monitors a training scan within the oral cavity of a patient in order to display training information, the automated training system comprising:
one or more processors; one or more memories that are accessed by the one or more processors; a display device; and computer instructions, stored in one or more of the one or more memories that, when executed by the automated training system, control the automated training system to
display a training user interface on the display device,continuously captures images of multiple surfaces of a three-dimensional, solid object from a wand that illuminates the one or more surfaces and receives reflected and scattered light from the one or more illuminated surfaces as the wand is moved along a trajectory to scan the one or more surfaces during the training scan,computes and stores, in one or more of the one or more memories, an ordered set of spatial positions and orientations of the wand by matching images of the captured images to projections of a previously created three-dimensional digital model of the solid object, andcomputes and displays, within the user interface on the display device, information regarding the accuracy and efficiency of the training scan from the stored ordered set of spatial positions and orientations of the wand.
