Abstract
A method performed by a surgical system. The method includes receiving a first image from an endoscope, the first image having a surgical instrument at a first location within a field of view of the endoscope. The method matches a three-dimensional (3D) model of the surgical instrument to the first image. The method receives a second image receives a second image from the endoscope, the second image having the surgical instrument at a second location within the field of view of the endoscope, and matches the 3D model of the surgical instrument to the second image. The method estimates a distance between the first and second locations based on both matchings and one or more parameters of the endoscope.
Claims20
A method comprising:
- receiving a first image from an endoscope, the first image having a surgical instrument at a first location in a surgical site within a field of view of the endoscope;
- matching a three-dimensional (3D) model of the surgical instrument to the first image;
- receiving a second image from the endoscope, the second image having the surgical instrument at a second location, which is different than the first location, in the surgical site within the field of view of the endoscope;
- matching the 3D model of the surgical instrument to the second image;
- and
- estimating a distance between the first and second locations determined from both matchings and one or more parameters of the endoscope.
A non-transitory machine-readable medium having instructions which when executed by at least one processor:
- receive a first image from an endoscope, the first image having a surgical instrument at a first location in a surgical site within a field of view of the endoscope;
- match a three-dimensional (3D) model of the surgical instrument to the first image;
- receive a second image from the endoscope, the second image having the surgical instrument at a second location, which is different than the first location, in the surgical site within the field of view of the endoscope;
- match the 3D model of the surgical instrument to the second image;
- and
- estimate a distance between the first and second locations determined from both matchings and one or more parameters of the endoscope.
A method comprising:
- receiving an image from an endoscope, the image including a first surgical instrument and a second surgical instrument at a surgical site within a field of view of the endoscope;
- matching a first three-dimensional (3D) model of the first surgical instrument and a second 3D model of the second surgical instrument to the image;
- and
- estimating positional data associated with the first and second surgical instruments determined from the matching and one or more parameters of the endoscope.
