What is the Deviation analysis?[edit | edit source]
This tool supports you in detecting deviations between two point clouds or between point clouds and IFC models.
Deviation analysis application
Step 1: Target Selection
- Click on the wrench icon to access the deviation analysis tool
- Select one or multiple point clouds you wish to use as reference (choose a primary point cloud, either dedicated or georeferenced, to serve as the anchor for the other point clouds)
- Click “Next” to proceed with Step 2
Step 2: Source Selection
- Choose the point cloud you wish to analyze
- Click “Next” to proceed with Step 3
Step 3: Data Filtering
- Select the desired tool for point selection from the available options
- None (Rotation)
- Box Selection; left-click + hold and drag mouse across the screen in desired area
- Polygon Selection; left-click to select multiple points on point cloud for the desired area – close or finish Polygon by clicking on the first point again
- Lasso Selection; left-click + hold and drag mouse to enclose the desired area
- Click on the Reset icon in Selected Points Action to revert and undo previous selections
- Click on “Next” to proceed with Step 4
Step 4: Processing
This step may take a few minutes. Once it is finished, a green check mark will appear indicating successful processing.
- Click "Next" to proceed with Step 5
Step 5: Analysis
This section functions as a tool for examine the computed deviation. Green represents 0cm of deviation, while red indicates the highest level of deviation.
- Toggle the wireframe view by clicking on the checkbox next to "Use wireframe view for models"
- Click "Close" to end the tool
