1. A system comprising:
a dental tray shaped to at least partially surround a plurality of teeth of a dental arch;
a first array of cameras attached to the dental tray, wherein each camera of the first array of cameras has a fixed position and orientation relative to one or more other camera of the first array of cameras, the first array of cameras configured to generate a plurality of images comprising image data of at least a portion of the dental arch; and
a processing device to:
receive the plurality of images comprising the image data of at least the portion of the dental arch;
stitch the plurality of images comprising the image data of at least the portion of the dental arch together based at least in part on calibration data specifying predetermined image stitching parameters for combining the plurality of images, wherein the predetermined image stitching parameters are based on predetermined fixed relative positions and orientations of cameras from the first array of cameras; and
generate a three-dimensional model of the plurality of teeth based on the stitched plurality of images.
