Making panoramas using
PtAssembler, Autopano and Enblend

 


1. Setup of Autopano and Enblend in PtAssembler

Download Autopano here and unzip the package in some folder.

Launch PtAssembler (Warning : this tutorial is for version 2.4.2 and above) and go to the Preferences menu, tab Plugins :

You should put in the autopano directory the path where you unzipped autopano.

The optional command line arguments can be used to improve the result. Leave it to the default value for standard use.

For Enblend, you also have to download it : http://www-cad.eecs.berkeley.edu/~mihal/enblend and unzip it in a folder. Then in the dialog box, just below Autopano Parametes are located the parameters for enblend. Just Browse for the enblend.exe.

2. Using Autopano in PtAssembler

Let's add some picture in the project (button Add) in the "Step 1" Tab.

Then select all files and HIT the "autopano selected" button (bottom right).

PtAssembler will shows you the script used to call autopano :

After calculation, PtAssembler displays another dialog box about the number of control points found by autopano.

Just hit OK.

3. Optimizing

You first have to set the FOV for every picture. So go to "Step 2" tab and Hit "Calculate using Image EXIF Data".

Then you should also select the type of Panorama Projection you want : Rectilinear, Cylindrical or Spheric.

Go to "Step 4" tab and hit "Auto-Optimize" button. PtAssembler has a really great modified optimizer which allows you to make this stage fast and stable.

After the optimization, it asks you for an automatic preview (and sets the output size parameters automatically). Here's the preview produced by PtA :

4. Rendering with enblend

 

Then go to "Step 5" Tab, select "TIFF / Enblend" for Output File Format, and hit create. It's done !
