Using the results

Once a calibration has been uploaded to artoolkitx.org, it will be immediately available to you and other users using the same combination of device and/or camera, and camera resolution. Note that if an exact camera resolution is not calibrated, the artoolkitX runtime will look for another calibration with the same aspect ratio (e.g. 16:9 or 4:3) since generally the operating system of each device will have the same lens intrinsics for camera modes that have the same aspect ratio but different sizes.

Once a calibration has been fetched from artoolkitx.org by the artoolkitX runtime, it is cached on-device for future use, by default for 365 days.

If you have chosen to save the calibration locally, it will be saved with a filename that captures the device name, camera index, resolution and whether the device is front- or rear-mounted (where that is meaningful). The file can be loaded into artoolkitX in the same way as the default camera_para.dat file supplied with the artoolkitX developer SDK. For many of the command-line utilities, the calibration file can be selected by using the --cpara filename command-line parameter.
