List of commands

Description

The tool OriConvert is a versatile command used to:

• Transform embedded GPS data from text format to MicMac's Xml orientation format.
• Transform the GPS coordinate system, potentially into an euclidean coordinate system.
• Generate image pattern for selecting a sample of the image block.
• Compute relative speed of each camera in order to determine and correct GPS systematic error (delay).
• Importing external orientation from others software: to come.

Syntax

The global syntax for OriConvert is :

mm3d OriConvert Format_Specification Orientation_File Targeted_Orientation

Allowed commands

• OriTxtAgiSoft
• OriBluh
• OriTxtInFile

Results

OriConvert produce an MicMac orientation based on georeferencing data. You cannot use directly this orientation for processing tools like AperiCloud or C3DC, launch before a CenterBascule.

Workflow

You can launch the OriConvert whenever you want, but of course before orientation tools.
Previous Command : ~
Next Command : CenterBascule,Campari etc...

OriTxtAgiSoft

This tools is designed to convert orientation from Agisoft PhotoScan into MicMac orientation format.

Example

OriBluh

Example

OriTxtInFile

GPS and attitude extracted from telemetry logs are generally structured as followed :

image latitude longitude altitude yaw pitch roll
R0040438.JPG 50.5860992029 4.7957755452 375.046 319.9 8.2 -2.1
R0040439.JPG 50.5864719060 4.7953921650 376.604 319.4 10.1 3.6

In this example (from the UAS GrandLeez dataset, file GPS WPK Grand-Leez.csv), column titles are specified on the first line. Nevertheless, MicMac has its own convention regarding column title. We have to add columns specs but with the symbols K, W, P standing for kappa, omega and phi.

#F=N Y X Z K W P

#image latitude longitude altitude yaw pitch roll

Example

Once the file has been modified, the following command can be used:
