Quick Start with AeroSys-AT Step by Step Tutorial

Step 1: Gather Data Files Refined Photocoordinate Data File(s) Refined Photocoordinate Data File(s) Export to PAT-B format, *.ptb Export to PAT-B format, *.ptb –Refined for radial lens distortion and fiducials –No interior (fiducial) points listed, only relative points –Units in Millimeters Ground Control Data File Ground Control Data File AeroSys native format, *.CTL AeroSys native format, *.CTL ptID, X, Y, Z, Sxy, Sz ptID, X, Y, Z, Sxy, Sz

Sample PAT-B format

Sample AeroSys *.CTL format CTL Project: City of Saint Paul, MN

Put *.ptb & *.CTL into Data Dir

So Far …..

Set the photocoordinate type … Click on the “Photocoordinate Type” tab Click on the “Photocoordinate Type” tab Select Attributes Select Attributes Format: e.g., PAT-B Format: e.g., PAT-B Processing: Raw vs. Refined Processing: Raw vs. Refined Parsing: Paired vs. Un-Paired Parsing: Paired vs. Un-Paired

Is Camera Info in Data Base? Is this block using a “New” camera, i.e., one that is not in your local AeroSys-AT camera data base? Is this block using a “New” camera, i.e., one that is not in your local AeroSys-AT camera data base? If YES, then click on the tab labelled If YES, then click on the tab labelled “Camera Data base” “Camera Data base”

Adding a new Camera …. Click on the blue arrow icon to add a new camera to the data base … Camera Editor GUI appears Click on the blue arrow icon to add a new camera to the data base … Camera Editor GUI appears

Add the new camera Info Click on the “New” button to put the gui into editor mode Click on the “New” button to put the gui into editor mode

Enter Camera Info …. Type in the camera calibration info into the GUI Type in the camera calibration info into the GUI Or Or Click on the “yellow” file open icon to import an existing *.CAL data file Click on the “yellow” file open icon to import an existing *.CAL data file Click the “Done” button to enter the camera Click the “Done” button to enter the camera Click the “Select_OK” button to finish Click the “Select_OK” button to finish

Enter Block info Click on the Block Configuration tab Click on the Block Configuration tab

Select Number of Cameras … If one camera … If one camera … If more than one … If more than one … To add more cameras to the list, select the camera name in the drop-down combo and then click the “green” plus icon button To add more cameras to the list, select the camera name in the drop-down combo and then click the “green” plus icon button

Select your PAT-B data file Click on the “all-in-1- file” choice button Click on the “all-in-1- file” choice button Click the green plus icon to select the *.ptb file Click the green plus icon to select the *.ptb file

Pre-Check the block contents … Click on the green check button to pre- parse the *.ptb file to check its contents Click on the green check button to pre- parse the *.ptb file to check its contents

Transfer Block Info to GUI … Click on the green up-arrow button Click on the green up-arrow button Click on the “Save” project Button Click on the “Save” project Button

Time Saving Step …. Click on the “export” button to parse the *.ptb file into the native AeroSys-AT file formats: *.REF & *.CAL Click on the “export” button to parse the *.ptb file into the native AeroSys-AT file formats: *.REF & *.CAL

So far … We have set up : We have set up : Project basename Project basename Project Data Directory Project Data Directory Project Ground Control file Project Ground Control file Selected a camera for the block Selected a camera for the block Translated *.ptb to *.ref & *.cal Translated *.ptb to *.ref & *.cal Now we are ready to start the bundle Pre-Processing steps … Now we are ready to start the bundle Pre-Processing steps …
