Data Processing
Extract the Clip Identification Region
Before measurement, you need to extract the surface data for clip identification and remove noise in the data to enhance the data stability and accuracy. Use the Filter Surface Points by Normals Step to extract the surface data for clip identification and remove noise in the data.
The detailed instructions are as follows:
-
In the parameter configuration panel of the Step, select the Use Feature Region option and adjust the region to include the surface data for clip identification.
-
Adjust other related parameters to remove noise.
After the Step is run, it will output the processed surface data:

The Filter Surface Points by Normals Step is very effective in removing noise, especially for obtaining flat surface data. When the noise is slanted or consists of irregularly scattered points, this Step can achieve good denoising results.
-
You can adjust the Max Polar Angle parameter to filter out slanted noise of varying degrees (recommended value: 60°) and adjust the Remove Noise parameter to filter out irregular points of varying degrees. Adjusting both parameters can produce better results. For more details on parameters, see Angle-Based Filtering.

Next, you can use the extracted surface data to measure the number of clips.
