Getting Started

The piping module inside of EdgeWise offers a fully automated algorithm that performs automatic pipe extraction. This guide will walk you through the steps necessary to perform automatic pipe extraction through process scans.

The Piping workflow is designed to start with full automation and then move on to semi-automated extraction. However, there are some cases where you may only need to extract a small portion of the entire point cloud. There are other cases where QA would take longer than starting from scratch. In these cases, you may start with Semi-Automated Extraction instead of starting with full automation. Skip straight to the article above if these cases apply to your project.

Process Scans

Upon clicking Open you will be greeted with the Process Scans Options Dialogue box. From here, adjust settings for generation of the Point Database as well as automatic pipe extraction. The Save File Name and Save File Location can also be adjusted here.

  • Minimum Number of points to detect a pipe: Used to eliminate smaller, less reliable surfaces. If this setting is too high, you will miss smaller features, but if you set this too low, the software will classify noisy, erroneous features as cylinders/pipes.
  • Distance Tolerance: is the distance for how far away from the cylinder a laser point can be before it is excluded. If you are using a scanner with more noise, then you should increase this tolerance.

Once your settings are adjusted to your liking, click Next, review the Process Scans Summary and click Start.

EdgeWise will begin to process scans, and when finished will produce your Point Database and Pipe Model.

Once EdgeWise has finished producing your pipe model, you can proceed to the Piping QA Process
