Introduction to the Workflows in HERON Desktop
1. Single Trajectory
This is the simplest workflow in HERON Desktop software to post-processing HERON® trajectories.
For any single HERON® acquisition acquired by a HERON® mobile mapping system, its trajectory will go through this principle workflow from:
Project creation > Import HERON raw data > Odometer > Create maps > Global Optimization > Export to Reconstructor > Import into Reconstructor.
For more details see Single Trajectory Workflow.
2. Multiple Trajectories
This workflow is dedicated for projects requiring more than one HERON® acquisition to complete the survey. In Heron Desktop, all of these acquisitions can be aligned together as a complete project and be ready to export as a whole.
After doing trajectory processing for each HERON® acquisition, following the fundamental workflow
Project creation > Import HERON raw data > Odometer > Create maps (done) [*] > Global Optimization > Export to Reconstructor > Import into Reconstructor
[*] Up to Create maps operation is done, two or more HERON acquisitions can be selected and merged together in Global Optimization, then will be exported as a complete survey.
For more details see Multiple Trajectory Workflow.
3. Usage of Constraints
The ability to integrate external data as control points and/or other processed 3D data (meshes, 3D point clouds, mobile mapping data, UAV, ...) is one of the unique features offering for HERON® users.
As these constraints are processed, have very good level of accuracy and are possibly georeferenced in global coordinates; where they are integrated with HERON® raw data in HERON Desktop, HERON® raw data will directly aligned with these constraints to optimize it global accuracy eliminating the global accumulated drift which results from laser sensor limitation.
This workflow will be done in HERON Desktop software.
External data will be integrate with HERON® data in Global Optimization by using Reconstructor®.
For more details see Usage of Constraints Workflow.
4. Tracking
HERON Desktop software allows you to import external 3D data in the stage of Trajectory processing, by integrating HERON® raw data directly with the external data. You can expect to achieving survey-grade with Tracking add-on, only if it is licensed.
Starting from a high level of accuracy of external 3D data, the external data is imported into HERON Desktop and by using Tracking Odometer function, every single pieces of HERON® raw data will be aligned directly with the external data; the global accuracy of external data becomes HERON® data accuracy constraint.
In addition, during process, the Tracking workflow also highlights the differences between external data and HERON® Data. Any detected changes/differences during the process will be recorded and saved to the processed 3D point cloud as a color layer.
