Fit Plane to Surface
Description
This Step is used to fit a plane based on a selected region or all data. The fitted plane often serves as the reference plane for other Steps.
Workflow
The process of configuring this Step is shown below.
-
Configure the input. Connect the ports manually or select the input(s) under Input in the parameter configuration panel.
-
Determine whether to use feature region. For a feature region used, you need to set Feature Region Mode. For more information, please refer to Use Feature Region.
-
Select the desired output(s) under Output. For an expandable output item, click ▶ and configure the Min and Max values of the acceptable range.
Parameter Description
- Use Feature Region
-
Feature region defines the area to be processed by the algorithm. When this option is selected, this Step will only process data within or outside the feature region.
Default setting: Unselected
Instruction: Complete the configuration according to the actual requirement.
- Feature Region Mode
-
Once Use Feature Region is selected, this parameter is used to select whether to process the data within the feature region or outside it.
Options: Include data in Region, Exclude data in Region
Default setting: Include data in Region
Instruction: To process data within the feature region, select Include data in Region; otherwise, select Exclude data in Region.
|
For other parameter settings of the feature region, please refer to Set the Feature Region. |
Output Description
Select the output item(s) according to the actual measurement requirements. Then the corresponding data will be output after the Step is run.
|
If you select an expandable output item, you must expand it by clicking ▶, and then set the Min and Max values to determine the acceptable range. If the output value falls within the acceptable range, the measurement item is judged as passing (OK), or else it is judged as failing (NG). |
| Output Item | Description |
|---|---|
Standard Deviation |
The standard deviation of the points used to fit the plane from the plane. |
Min Error |
The minimum error of the points used to fit the plane from the plane. The distance is positive for points above the plane and negative for points below the plane. |
Max Error |
The maximum error of the points used to fit the plane from the plane. The distance is positive for points above the plane and negative for points below the plane. |
Distance |
The distance from the origin to the plane. |
Fitted Plane |
The plane fitted to the selected surface. |
