One-Click Workflow
Function Overview
The one-click workflow can use newly created or imported image project (.liaep) files, together with point clouds or externally generated DSM/DEM images, to run image alignment and orthomosaic generation.
Note: The point cloud and image project used in a point-cloud-combined workflow must be in the same coordinate system and at the same location. Otherwise, the generated product coordinates will not match and processing cannot be completed.
Usage
Combined Point Cloud Workflow
The combined point cloud workflow uses point clouds to generate DSM/DEM. The generated DSM/DEM is then passed into the image processing workflow for orthomosaic generation.
- Load the point cloud and image project or image project group to be used into the window. If an image project group is used, after image alignment is executed, all blocks are aligned in sequence, and all results are merged into one image project as the input file for subsequent workflows.
- Select the workflows to execute according to the actual situation. For an orthomosaic workflow based on point-cloud DSM, it is recommended to select Smooth, Resample, Remove Outliers, DSM, Image Alignment, and Orthomosaic. For an orthomosaic workflow based on point-cloud DEM, it is recommended to select Smooth, Resample, Remove Outliers, Classify Ground Points, DEM, Image Alignment, and Orthomosaic.
- Click Run and set parameters for each function in the pop-up dialog box. In the orthomosaic parameter page, select DSM-based stitching for workflows using point-cloud-generated DSM, or DEM-based stitching for workflows using point-cloud-generated DEM. For point cloud parameters, refer to Smooth, Point Cloud Subsampling, Remove Outliers, Classify Ground Points by PTD, Point Cloud to DSM, and Point Cloud to DEM. For image alignment and orthomosaic parameters, refer to the Parameter Settings section.
- After confirming the settings, click OK to execute the workflow.
Non-Point Cloud Workflow
When only image alignment needs to be completed, when orthomosaic generation is not required, or when an external DSM/DEM is provided, image alignment and orthomosaic workflows can be performed directly without using point clouds.
- Load the image project or image project group to be used into the window. If an image project group is used, after image alignment is executed, all blocks are aligned in sequence, and all results are merged into one image project as the input file for subsequent workflows.
- According to the actual production requirements, select only the Image Alignment and Orthomosaic workflows. Clear all function buttons related to point clouds.
Note: The orthomosaic workflow requires image alignment to be executed first, or an image project that has already been aligned.
- Click Run and set the image alignment parameters and orthomosaic parameters in the pop-up dialog box. In the orthomosaic parameter page, select custom model stitching and set the path of the external DSM/DEM. For other parameter descriptions, refer to the Parameter Settings section.
- After confirming the settings, click OK to execute the workflow.
