Pavement Distress Analysis Workflow
Function Description: Connects the standard image-based pavement distress analysis process in Basic mode and runs Subsampling, Classify by Deep Learning, Image-based Distress Detection, Sample Units Generator, PCI, and Export Report in order. The steps share inputs and intermediate results, reducing repeated data selection between functions.
Input Data
Before running the complete workflow, load the point cloud and trajectory, together with photos and an image list file (*.imglist) matched to the point cloud. The detection step in this workflow is Image-based Distress Detection. To detect geometric deformation such as rutting, depression, potholes, bumps, swell, corrugation, and shoving, run Point Cloud-based Distress Detection separately.
Operation Steps
1.Select the point clouds and output directory, and select the functions to run
2.Click Run to open the function dialog
3.Check the parameters of each selected step in order, then click Run to start processing
4.After processing, check the "Distress", "Sample Unit", and "PCI Section" layers and confirm that the report matches the current project results
Parameter Settings
Main Parameters
Files: Select the point cloud files to process
Output Directory: Set the output location for processing results
Parameters: Open and configure the parameters for the selected steps
Step Descriptions
| Step | Description |
|---|---|
| Subsampling | Uses Minimum Point Spacing with a spacing of 0.01 m to reduce point count and accelerate subsequent processing |
| Classify by Deep Learning | Separates ground points to improve distress detection accuracy |

| PCI | See PCI |
| Export Report | See Export Report |
Result Check
After the automatic workflow is complete, confirm that the "Distress" layer was created and aligns with the road, the "Sample Unit" layer covers the target pavement, and the "PCI Section" layer and report were generated successfully. The automatic workflow does not include Distress Verification or Sample Units Editor. For formal, accurate statistics, complete the Recommended Workflow, then recalculate PCI and export the report again.
