This walkthrough illustrates the step taken to clean a project with the tool.
The first of ReCap’s Data Services; Project Cleanup eliminates the pain of rigorously finding and removing unwanted artifacts inadvertently captured while in the field. This is great for identifying objects such as people or cars who are constantly moving through a static environment.
Once initiated, a brief settings dialog provides the ability to adjust the precision of the tool, affecting the eventual results.
By default the Project Cleanup tool is able to identify a base-line set of points that are “bad” within a project with relative ease. However, the nature of the data means that, in some instances, points that would be obviously bad to the human eye can be missed. This can occur even when those missed points are located directly next to other identified “bad” points.
Precision is designed to mitigate this issue and return a better overall result. By using the easily identified “bad” points as a guideline the tool will expand its selection to include additional points within a certain radius of any given “bad” point. Lower precision will select a larger region around the “bad” points resulting in more points being selected, while higher precision will select a smaller region resulting in fewer.
Once the process is completed the identified points are automatically assigned to a new scan region for review. Additional editing can also be done so that any outlying issues can be corrected in the selection.
These points can be deleted from the project through the Scan Region’s contextual tools.
Any points already associated with a scan region will automatically be removed from it and assigned to the newly created “cleaned points” scan region. Locking scan regions will omit those points from the cleanup process. Sectioning a project and locking certain regions is a handy way to focus on specific areas within the project that you know are prone to this type of noise.
