Abstract: A three-dimensional (3D) measuring instrument includes a registration camera and a surface measuring system having a projector and an autofocus camera. For the instrument in a first pose, the registration camera captures a first registration image of first registration points. The autofocus camera captures a first surface image of first light projected onto the object by the projector and determines first 3D coordinates of points on the object. For the instrument in a second pose, the registration camera captures a second registration image of second registration points. The autofocus camera adjusts the autofocus mechanism and captures a second surface image of second light projected by the projector. A compensation parameter is determined based at least in part on the first registration image, the second registration image, the first 3D coordinates, the second surface image, and the projected second light.

Abstract: Provided are a calibration method for splicing light source modules, a projection method, a 3D printing method, a calibration apparatus, a 3D printer, and a non-volatile computer-readable storage medium. There are at least two light source modules. The calibration method includes: performing optical calibration processing on each of the light source modules, wherein a splicing overlapping area is present in projection regions of the light source modules subjected to optical calibration processing; and performing, on the basis of the splicing overlapping area, calibration accuracy inspection on each of the light source modules subjected to optical calibration processing.

Abstract: A method for determining a lens distortion correction comprising:
- obtaining (503) an indication of a first feature and a first corrected position of the first feature in a first corrected image frame, the first corrected position is based on a first lens distortion correction of a first uncorrected position of the first feature in a first uncorrected image frame captured by the camera when equipped with a first interchangeable lens;
- detecting (504) a change of lenses on the camera;
- obtaining (506) an indication of a second feature and a second uncorrected position of the second feature in a second uncorrected image frame captured by the camera when equipped with a second lens;
- matching (507) the first feature with the second feature; and
- determining (509) a second lens distortion correction for the second lens based on a mapping between the first corrected position and the second uncorrected position.-

Abstract: Method and device(s) for provision of a pair of real world and image sensor correspondence points for use in calibration of an imaging system (405) for three dimensional imaging based on light triangulation. Said real world point (514-1; 529-1) being provided (801) as a first virtual intersection between a first real world line (512a; 527a) and a second real world line (512b; 527b). Said image sensor point (544-1; 554-1) being provided (802) as a second virtual intersection between a first image line (542a; 552a) and a second image line (542b; 552b). A first image (540a; 550a) by the imaging system comprises captured light that images the first real world line (512a; 527a) and a second image (540b; 550b) by the imaging system comprises captured light that images the second real world line (512b; 527b). The first image line (542a; 552a) corresponds to positions of intensity peaks of said captured light in the first image (540a; 550a) and the second image line (542b; 552b) corresponds to positions of intensity peaks of said captured light in the second image (540b; 550b).

Abstract: A computer-assisted medical system comprising a fluoroscopic imager having a full scan range in a surgical coordinate space and one or more processors. The processors are configured to perform a method including: receiving a first fluoroscopic image data set of a patient anatomy, the first fluoroscopic image data set obtained from the full scan range of the fluoroscopic imager; receiving at least one additional fluoroscopic image data set of the patient anatomy from the fluoroscopic imager operating in a constrained range substantially smaller than the full scan range; and constructing a first planar tomographic image from the first and at least one additional fluoroscopic image data sets.
