Examples are disclosed for calibrating devices used to generate images of a three-dimensional object data model (“3D model”). An initial 3D model that represents an object can be received. The initial 3D model can include a plurality of images aligned relative to one another. The plurality of images can be generated using a plurality of devices. A realignment of the plurality of images can be performed. An updated 3D model can be generated based on the realignment. At least one calibration of at least one of the plurality of devices can be determined based on a comparison of the initial 3D model with the updated 3D model. Calibration data can be provided to a computing device. The calibration data can be indicative of the at least one calibration. The computing device can be operable to use the calibration data to perform the at least one calibration.
