Command Description
The Points to Cloud Report command compares points to a point cloud region or scan to determine the nearest scan point to the selected point and provides a comparison between the derived point pairs. This is a useful tool to compare measured ground check points with computed point clouds from drone surveys and slam scans.
Measurement Tab
- Click in the Points selection field and then in a graphic view select the points to compare to the cloud. Click Options for additional selection options.
- In the Point cloud region selection pick a region to use for the comparison.
- Settings:
- Enter a Horizontal search radius to be used to scan the point cloud and find any scan points that fall in this radius from the point being compared.
- Enter a different Vertical search radius if required or leave blank to use the same value as the horizontal.
- Enter the Number of scan points to report around each selected point.
- Check the Show comparison lines in view to see the vectors between the point and the scan points.
- Check the Add text on measurement box to add the text results directly to the screen as you press the Measure button. The settings for this are found on the Text tab.
- Press the Measure button to check the points and populate the Measurements box.
- The Configure columns button allows the user to nominate which measured values are displayed in the measurements text box and reported.
- Measurements:
| Option | Description |
| Point ID | Comparison point ID |
| East | Easting coordinate |
| North | Northing coordinate |
| Elevation | Elevation |
| # Scan pts | Number of scan points that are found within the search tolerance |
| Delta XY | Horizontal distance delta between the point and the scan point |
| Delta Z | Vertical distance delta between the point and the scan point |
| 3D dist | Slope distance between the point and the scan point |
| Mean delta XY | Mean horizontal distance of the scan points reported |
| Sigma delta XY | Standard deviation of the horizontal distance of the scan points reported |
| Mean delta Z | Mean vertical distance of the scan points reported |
| Sigma delta Z | Standard deviation of the vertical distance of the scan points reported |
| Mean 3D | Mean slope distance of the scan points reported |
| Sigma 3D | Standard deviation of the slope distance of the scan points reported |
- Press the Create Report button to report all the selected fields into an Excel sheet.
- Press the Clear button to clear the measurement table.
- Click Close to close the command pane.
Text Tab
- Go to the Text tab to draw the measurements taken and recorded in the measurement tab to text.
- Define the layer - A layer called “Text – PointsToCloudReport” is automatically created
- Choose a Colour
- Choose a text Style
- Enter a text Height
- Enter a Gap between the location and the start of the text.
- Check the Draw leader line with gap box to add a leader line when a gap has been used
- Choose a Line style to be used when drawing the comparison vector lines.
- Check Include data prefix to include the “Data” type as a prefix to the text on screen.
- Create Text button will create text of all the measurements taken and currently active on the measurement tab.
- Clear Layer button will delete everything on the selected layer that contains the text.
Note: This is not designed to work on vertical walls.
