Compute Volume - Steps

1. Capture the scene that contains the volume to be computed.

2. Select Volume Computation on the project view.

3. Define the base of the volume by manually adding points.

4. Compute the volume.

5. Export the results as a PDF report.

Compute Volume - Detailed Description

Once selected Volume Computation, a densification process will be launched automatically to facilitate the entire workflow. This process can be canceled at any time by pressing the cancel button.

To compute the volume, it is necessary to define its base by simply clicking on the screen to add points.

To remove a point, tap on the icon .

To change the location of a specific point, press on the point and drag and drop to the new location.

To delete a specific point, press on the point and drag and drop to the trash icon at the bottom of the screen.

To remove all the points created, tap on the icon  

Any number of points can be added to accurately define the base of the volume. However, a minimum of three points is required to initiate the computation.

Once the computation is complete, the values of the volume(s) can be found on the dropdown list.

Volume(s) can be deleted with the trash icon 

Mesh volume is displayed on the point cloud.

Once the volume is computed, a layer containing the volume measurements will be generated and the values will be displayed. This layer can be toggled on or off as needed.

The volume measurements can be exported as a PDF or CSV file by selecting the export icon.

The uncertainty estimation is based on a theoretical model, which accounts for different sources of uncertainty, such as the point cloud noise, completeness and density. The model does not take scale errors (which can be prevented using an RTK receiver) or errors in the base surface into account. An extensive validation of the theoretical model has been carried out by running experiments on various types of objects.

PDF Report - Details

PDF Report Contents

The first page of the PDF report includes the following information:

• File name.

• Date created.

• Description.

• Version of the PIX4Dcatch application used for computation.

This is followed by one or two additional pages, depending on the number of volumes computed.

For each volume type (cut and/or fill volume):

• Computed volume value with associated uncertainty.

• 3D area value, including the 3D coordinates of the points defining the base.

• 3D perimeter value, including the 3D coordinates of the points defining the base.

• A 3D view of the volume.

• A top-view of the volume.

Best practices for Accurate Volume Measurement 

Capture the full dimensions of your object

• Ensure the entire object is captured, including both the top and bottom surfaces, to calculate the correct volume.

• Perform a closed-loop capture to improve spatial consistency.

• Remove any unwanted surrounding objects before capture, if possible.

Obtain an accurate 3D model

• A precise point cloud is essential for reliable volume computation.

Precisely define the base of the volume

• Use multiple perspectives when drawing the base polygon.

• Add sufficient points to ensure the base accurately matches the object's footprint.

• Remove any point that appears to be incorrectly placed.
