Getting Started with Vercator Software

This article describes the quickest way to get started with Vercator Desktop software.

Vercator Desktop runs as a series of work modules that can be run separately or as a chain in one process. The fastest way to get going is to follow the step-by-step guide below. The overall process can be seen in the flowchart below.

In some cases, this may not produce the most optimal result and therefore parameter tweaks or manual registration may be required to obtain the desired result. For reprocessing some stages please read about the Processing Requirements Editor.

Formats

Vercator Desktop requires 1 scan per file only.

Due to the nature of the algorithm Vercator uses, scan data that is input in pts may cause issues if they are not generated with the scanner position at 0,0,0. This is because the scanner position has to be calculated.

This is not needed for all other supported formats: flse57, zfs or ptx and we recommend using these.

Step-by-step guide

  1. Create a new project
  2. Set parameters as needed based on the data characteristics
  3. Run Vercator Desktop
  4. Verify result

The process

Step 1: Create new project configuration

Open Vercator and the default interface appears as below.

Either a new or pre-existing configuration must be used to run the program. To do either, select:

  • File -> Open… for an existing configuration, or
  • File -> New Configuration… for a new one

Vercator Software Open File

If a new configuration is chosen, then you are asked for a folder to store the working project files in.

Then, after clicking Add Scans.., the following window opens to aid with the creation of a new project. The setup is composed of three stages.

  1. Add scans to the project
  2. Drag scans to the level(s) required to build the network (this can be diagrammatic or roughly positionally correct)
  3. Connect the matching pairs of scans into a tree network with no loops or disconnected elements

This is crucial to a successful registration, so please read this article to fully understand the process: Scan Network Creation.

The Scan Network can be edited when needed from the link on the Configuration tab.

Summarised the network rule is:

  • The network must form a tree, so loops or isolated separate fragments are not currently allowed

Once created and Finish is selected, the configuration form will auto-populate as below.

Step 2: Configuration Parameters

Configuration settings can now be accessed and changed (see Configuration Tab article for more detail). The amount of steps that are run is dictated by the selector on the right of the config screen for each step. This allows for all processing stages to be run sequentially or just one or a number of steps to be run or re-run with different parameters.

It is recommended to run up to the end of the coarse registration report and disable the last 3 stages so that the coarse registration can be user verified before the intensive fine registration begins.

For example, one may wish to check the success of the coarse registration before performing the later stages to check for problematic scan pairs that fail to register automatically. Therefore the user would deselect all the stages after the Coarse Registration Report as below.

Step 3: Start Processing

Once set up and saved, go to the top of the Configuration tab and press Start to execute the program. The view will switch to the current job progress for monitoring the work done.

Verify Coarse Registration

Once Vercator is finished the result can be verified as in the article: Verifying Coarse Registration.

Once the coarse registration result is verified as good, the fine registration and fine registration report stages along with the scan transformations export stage can then be run by repeating step 2 above with only those stages enabled.

Verify Fine Registration

Details about the quality of the final registration can be found in the fine registration results tab as below.

The final registered scans will be in the ‘transformed’ folder in the chosen working directory which can be accessed from the Open Scan Results button. These can then be taken into other software packages to further process and visualise the result in 3D.

The project folder also contains a csv copy of the registration reports and the Vercator project file (.json).
