Volume Measurement

Brief: This tool is applicable to point cloud data and model data, which calculates filling, cutting and total amount relative to a reference height. It's commonly used in volume measurement of coal pile and hull.

Usage

Click Point Cloud > Measurement > Volume

Steps

1. It is suggested to adjust the window to top view before the tool is used. Select at least three points to generate the reference plane for volume calculation by left-clicking. Select the last point by double-clicking. The border of the selected region will be rendered in red and the dialog "Volume Measure" will pop up.
   
2. Set the cell size.
3. Set the reference plane of volume measurement. The options include minimum value, mean value and custom value.
4. Click the "Compute" button to generate the measurement result. The corresponding volume will be rendered in the scene, as shown below.
   
5. Click the "Export" button to export the result in *.pdf or *.txt format.

Settings

• Cell Size: It defines the smallest unit size for calculation. The smaller the value is, the more accurate the calculation is.
• Basic Height: It defines the reference plane to calculate filling and cutting.
  • Minimum (Default): Use the minimum height of the selected points as the height of the reference plane.
  • Mean: Fit the best plane according to the selected points.
  • Custom: This value is specified by the user.

Note: This tool only works with point cloud data and model data in 3D view.
