Measurements

Viewer always connects to the primary AVEVA Point Cloud Manager dataset for measurements. This can be seen as a simple terminal onto a potentially huge point cloud offering sub-millimeter density, operational speed and the availability of an unlimited number of project scans. This means that any measurement interaction through a Viewer session has AVEVA Point Cloud Manager providing a detailed response to queries in moments. Measurements taken are therefore not ‘approximate’, and should be viewed as highly accurate, and in line with the expectations of engineering users of AVEVA Point Cloud Manager.

When using a Viewer project offline, the central project database will be updated when a user synchronizes their work. Additionally, users may not be able to extract an accurate coordinate when operating offline. In these situations, temporary field measurements may be fully resolved when back online. This guarantees the accuracy within Viewer sessions related to the full laser surveyed point cloud.

Measurement functions are accessed through the Viewer Tools "Pill" Menu. To open the Tools Menu click/tap the desired icon at the bottom of the BubbleView as shown below.

Measurements will be created in the group that is currently selected in the Properties Panel on the right hand side of the interface. If no group is selected in the Properties Panel, the Measurement is created at the top-level Measurement node.

To access the Properties Panel, select the Show Properties Panel icon at the top-right of the Viewer interface.

Measure a single point

To measure a single point:

• Click/tap the ‘Point Measurement’ tool from the Tools "Pill" Menu then click/tap the point you wish to measure.

  

  The point coordinate value will be returned to the Viewer user directly in the BubbleView.

  

Please note that measurements cannot be placed as accurately on mobile devices, due to the use of ‘finger picking’. If this is an issue, measurements can be repeated & replaced when back in a suitable environment.

The Properties Panel has provision for the user to input a relevant name for the measurement. After the input is given, other ‘live’ users of the project will see this following a project refresh.

When the measurement has been committed to the central database, a user may delete or rename it using the tools shown below. You can turn the deletion confirmation dialogue off in the Options menu under Sidebar > Confirm Entity Deletion.

To select multiple measurements for deletion, select the Toggle multi select option.

Measure between two points

Viewer users may also measure between two points. When the Point to Point Measurement is chosen, the user will be prompted to select both points within the BubbleView. Following this, the points will be accurately resolved on screen using the laser point cloud, and the results displayed within the BubbleView.

To measure between two points,

• Click/tap the ‘Point to Point’ tool from the Tools "Pill" Menu then click/tap the start and end points for the measurement calculation.

  

  The displayed results include the two-point coordinates selected, the overall distance and the delta values between them.

As with the single point measurement the point to point measurement will be shown in the Properties Panel. When the input is given, other ‘live’ users of the project will see this following a project refresh.

When the measurement has been committed to the central database, a user may delete using the Delete icon, after expanding the measurement. You can turn the deletion confirmation dialogue off in the Options menu under Sidebar > Confirm Entity Deletion.

Measure a pipe diameter

This function enables the user to quickly determine the diameter of a pipe. The user defines a line along the path of the pipe to be measured and its diameter is then calculated. Results are displayed in the BubbleView showing the diameter as an annotation, with a translucent pipe aid overlaid for clarity. The user can visually check the accuracy of results before adding a project measurement label in the Properties Panel.

Note: This feature is not available when in offline mode.

To measure a pipe diameter:

• Click/tap the ‘Pipe Diameter’ tool from the Tools "Pill" Menu then click/tap the start and end of the desired pipe.

  Point Cloud Manager will then calculate the ‘best fit’ cylinder using the path between the two points. Please note that these points have no direct impact with the results but offer a directional guide to the Point Cloud Manager fitting algorithm. When the calculation has been processed, a 3D representation of the pipe will appear on screen.

  

  The results are displayed in the BubbleView.

As with the other measurements the point to point measurement will be shown in the Properties Panel. When this has been input, other ‘live’ users of the project will see this following a project refresh.

When the measurement has been committed to the central database, a user may delete or rename it using the tools. You can turn the deletion confirmation dialogue off in the Options menu under Sidebar > Confirm Entity Deletion.

Note: All measurements listed in the Properties Panel can be located in the BubbleView by selection with a single click/tap. All visible measurements in the BubbleViews are also selectable by clicking/tapping on the measurement in the BubbleView which will highlight the measurement in the Properties Panel.

If there is insufficient data to calculate a measurement, the user will be informed through an error message.

Measurement feedback

In practice, all measurements are returned to the user within the active BubbleView. These are colour coded to represent the different axes, where X/Easting is red; Y/Northing is green, and Z/Elevation is blue.

You can copy the contents of these measurement callouts to the clipboard, to include in documents and spreadsheets. You can access this by tapping and holding/right clicking the measurement/Markup callout.

The user has control over the copied information through the form. To copy a part of the measurement information to the clipboard, simply click on it.

To save all the measurement/Markup information to a text file select Save.
