Processing Data Using TBC Photogrammetry Module

How to import the JXL file output into TBC and process WingtraOne photos.

Using TBC Photogrammetry Module to process data 

There is a video webinar to watch for step by step instructions that can be found here: WingtraOne / TBC workflow.

  • Starting with WingtraHub make sure you have the JXL option checked then run through the geotagging process. The JXL file will be produced with both PPK and Non-PPK geotags then the file will be in the OUTPUT folder.

  • Drag the JXL file into an open TBC project.

You need to keep the same file structure and naming convention if you copied the data from the SD card to a different location otherwise the images will not load in TBC.

  • It will load the images and Flightplan project in TBC. Under the Photogrammetry section, the workflow tends to flow from left to right in order.

  • The coordinate system should be established before importing the project or load in the calibration from the .JOB or .DC file. If it not set under the Photogrammetry tab click “Change Coordinate System.”
  • Drag the ground control point file into the TBC project specifying the format. 

  • View the ground control to see if it makes sense with the project in that the points are inside the mission area.
  • Under the Photogrammetry tab select “Advanced UAS” to run the "Quick Fit" initial processing.

  • Apply the "Quick Fit." 

The next step is marking the GCPs in the photos for absolute adjustments.

This is required for both PPK and non-PPK images because TBC doesn’t have the ability to specify accuracy which is required for full PPK processing. The results using PPK will be better than non-ppk, but will not be under decimeter accuracy.

Under “Advanced UAS” import the GCPs then proceed to mark them in at least 5 photos.

After the GCPs are marked click "Next" to move to the specifying the deliverables.

Click "Process" once the deliverables are specified and then view the report to view the quality of results.
