Abstract
The present teachings relate to a method for assisting an intraoral scan including providing an intraoral image of a patient, and providing an extraoral image; the extraoral image being representative of the position of an extraoral scanner part. The teaches further include generating, using the intraoral image and the extraoral image, a mapping function correlating the position of the extraoral scanner part with the position of the intraoral scanner part; and computing, using the mapping function, a desired extraoral position of the extraoral scanner part; the desired extraoral position corresponding to a preferable intraoral position of the intraoral scanner part. The present teachings also relate to a system, a device, a use, data, and a storage medium.
Claims15
A computer-implemented method for assisting an intraoral scan, comprising:
- providing, via an intraoral scanner part, an intraoral image of a patient;
- providing, via an image sensor, an extraoral image;
- wherein the extraoral image is representative of the position of an extraoral scanner part, said extraoral scanner part being rigidly connected to the intraoral scanner part,
- generating, using the intraoral image and the extraoral image, a mapping function correlating the position of the extraoral scanner part with the position of the intraoral scanner part;
- computing, using the mapping function, a desired extraoral position of the extraoral scanner part;
- wherein the desired extraoral position corresponds to a preferable intraoral position of the intraoral scanner part.
A system comprising:
- an intraoral scanner part, an image sensor, and a processor configured to:
- provide, via the intraoral scanner part, an intraoral image of a patient;
- provide, via the image sensor, an extraoral image;
- wherein the extraoral image is representative of the position of an extraoral scanner part, said extraoral scanner part being rigidly connected to the intraoral scanner part,
- generate, using the intraoral image and the extraoral image, a mapping function correlating the position of the extraoral scanner part with the position of the intraoral scanner part;
- and,
- compute, using the mapping function, a desired extraoral position of the extraoral scanner part;
- wherein the desired extraoral position corresponds to a preferable intraoral position of the intraoral scanner part.
A non-transitory computer-readable storage medium storing a program, comprising instructions which when executed by processor causes a computer system to
- provide, via the intraoral scanner part, an intraoral image of a patient;
- providing, via the image sensor, an extraoral image;
- wherein the extraoral image is representative of the position of an extraoral scanner part, said extraoral scanner part being rigidly connected to the intraoral scanner part,
- generate, using the intraoral image and the extraoral image, a mapping function correlating the position of the extraoral scanner part with the position of the intraoral scanner part;
- and,
- compute, using the mapping function, a desired extraoral position of the extraoral scanner part;
- wherein the desired extraoral position corresponds to a preferable intraoral position of the intraoral scanner part.
