Model Reprocessing & Editing Geo-Referencing Method
DatuBIM users can reprocess drone
imagery and data to improve model accuracy by adding ground
control points (GCPs) or
simply changing the geo-referencing method. Reprocessing a model can
be done without the need to open a new site and re-upload images. Here are
some basic rules:
Basic Rules
- When
you want to
edit the geo-referencing method, DatuBIM will
automatically show
you only the available options
that you can change them to.
- If the current
geo-referencing method is one of the available
options,
it will automatically be selected, and the "Reprocess model"
button becomes clickable.
This workflow allows you to reprocess the model without making any
changes or, in the case you are using GCPs, to add GCPs or correct the existing GCPs to
improve accuracy.
- Reprocessing a model uses up
credits of your image allowance, which is defined in your DatuBIM service package.
Editing a Flight's Geo-referencing Method
To
edit the geo-referencing method of a flight that was already processed, hover your
mouse over the desired
flight in the top flight timeline. The flight
information will appear with a pencil icon in the top right corner, as shown in
the figure below. Click the pencil to edit the flight.
This opens the Edit Flight Data dialog, which shows you the available
geo-referencing options. You may
keep the currently selected one or change it. Then press the "Reprocess
model" to move to the next step.
Besides changing to the different
geo-referencing method, you can use Model Reprocessing to:
- Introduce a new, more accurate set of GCPs.
- Fix the coordinates of existing GCPs.
- Change additional processing parameters, such as Switch RTK on/off, Switch Rolling Shutter compensation on/off.
Reprocessing the Model
Depending
on the selected geo-referencing method, pressing the "Reprocess
model" button will
be lead to different scenarios. - If the geo-referencing selection does not need any intervention from the user, the process simply completes all the way to the end.
- If the geo-referencing selection requires working on GCP's, the system puts the model in "Pending GCP Marking" status and waits for the user to take action.
When reprocessing older models, you can take advantage of the full power and recent improvements of DatuBIM, such as:
- Enhanced pre-processing methods
- Quality checks of imagery
- Use of checkpoints
- Accuracy reports
- Upgrades to our photogrammetry engine
