specific Embodiment approach 1

[0030] Specific implementation mode 1: The specific process of a superconducting cavity virtual frequency-cutting method in this implementation mode is as follows:

[0031] Step 1. Paste the scanning mark points ( image 3 The circle points in the orange and blue parts are the mark points);

[0032] Step 2. Calibrate the 3D scanner before the 3D scanner starts to work; after the 3D scanner is calibrated, set the shutter time to 6-7ms, and the resolution to 0.2-0.5mm, and then start to calibrate the conductor parts in the superconducting cavity. Scan to obtain the scanned model (scanned front model and back model);

[0033] The scan is divided into two parts: a front scan of the part and a back scan (the front is image 3 The inside is orange-yellow (also called the inner surface or high-frequency surface), and the back is image 3 Inner blue (outer surface). The frequency of the part is only related to the inner surface, not the outer surface. The purpose of scanning the ...

specific Embodiment approach 2

[0051] Specific embodiment 2: the difference between this embodiment and specific embodiment 1 is that in the step 1, the scanning mark points ( image 3 The circle points in the orange and blue parts are the mark points), the specific process is:

[0052] Paste scanning mark points on the conductor parts in the superconducting cavity that need to be scanned, and ensure that there are 3 to 4 mark points within a range of 15 cm (a circle with a diameter of 15 cm).

[0053] Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0054] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that: in step 2, the 3D scanner is calibrated before the 3D scanner starts working; after the 3D scanner is calibrated, the shutter time is set to 6-6. 7ms, the resolution is set to 0.2 ~ 0.5mm, and then start to scan the conductor parts in the superconducting cavity to obtain the scanning model (the scanned front model and the back model); the specific process is as follows:

[0055] The Calib RMSE of the 3D scanner after calibration is ≤0.13mm to ensure the accuracy of the instrument;

[0056] The Calib RMSE is the calibration root mean square error (Calib (Calibrate) is calibration, RMSE (Root Mean Square Error) is the root mean square error).

[0057] Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.
