Technical Field

The invention relates to the technical field of a 3D scanner calibration file loading mode, in particular to a loading mode of a handheld 3D scanner calibration file.

Background

Before scanning of the three-dimensional object, the handheld 3D scanner system itself needs to be calibrated. Calibration is very important because the 3D scanner needs to know under what environmental conditions it is scanning to scan accurate three-dimensional data. The calibration data is stored in a calibration file that needs to be loaded by the three-dimensional scanning software from the computer hard disk prior to the three-dimensional scan. The calibration file corresponds to the handheld 3D scanner device, and if the three-dimensional scanning software of the handheld 3D scanner device is replaced, the calibration file which needs to be loaded is replaced correspondingly. However, how to ensure that the calibration file corresponds correctly to the handheld 3D scanner device is a problem that is being addressed by the handheld 3D scanner manufacturers. The prior art scheme is as follows: the serial number is pasted on the handheld 3D scanner device, the calibration file corresponds to the serial number, a user needs to confirm whether the serial number of the handheld 3D scanner device corresponds to the calibration file before three-dimensional scanning, and then the three-dimensional scanning software loads the calibration file from the computer hard disk. However, the method requires the user to perform manual identification confirmation, increases the operation flow and the use difficulty, and has the possibility of identification errors. Therefore, how to implement a simpler loading manner of calibration files for a handheld 3D scanner and ensure that the calibration files correspond correctly is the research direction of those skilled in the art.
