Spherical Panorama Creation With AutoPano-Pro
On this page you can see step by step how to create a spherical photography from non aligned shots captured with the help of a nodal rotator and edited with this excellent software.
AutoPano-Pro is a commercial software based on Autopano, an excellent control points detector to stitch partially overlapping images.
Going on with the example started on the previous pages, on this page we'll create a Spherical Panorama from pictures taken with the help of a nodal rotator in three different rows. Of these, the two photographs that point to the scene's nadir have already been edited to crop the presence of the rotator out of the image. Altough Hugin is able to distinguish by itself the images belonging in a same panorama, we prefer for more accuracy to do this selection manually. We'll get started, then, by selecting our nine images and dragging the selection into AutoPano-Pro's main window to load them :
We can inmediately see the group of images in AutoPano pro's main window. If we wish to see them all at once it is possible to adjust the size of the icons by moving to the left or right the slider which can be seen at the lower part :
Now we can see all the images at the same time. AutoPano-Pro automatically recognizes the information corresponding to the camera which is included into the image files, but it does not know if the normal lens of it has been replaced or converted to a fisheye. It will be necessary to include this information manually. For this we'll click on the Image Properties button :
Then a new program's window will open showing the detail of the group's photographs, togheter with some data about them including the lens type :
Since the images are registered as taken with a lens of Standard type but the example's images have been taken with a Fisheye converter, the most practical way to modify all information is to select all the files :
Now we can edit at once the information corresponding to all images, by keeping the files selected to display the Lens Type menu and choose the Fisheye option :
After accepting this window will be closed and, back to AutoPano-Pro's main window, we can check th at the informed modification has been registered :
We are ready to start the control points detection to combine the overlapping areas between images by clicking on Detect :
While the process takes place we see a progress indicator and the stages of detection :
Now the detection process has ended and AutoPano-Pro has detected one panorama in the group, has created a preview of it and calculated some data about the image to be created :
Clicking on the Edit button we'll start the panorama editor in a new window. At a glance we can tell there is an error. The empty area at the nadir was foreseeable because we had cropped it out before creating the panorama, but the empty spot at the zenith tells us that the image that shows it has either been misslocated or unrecognized :
To try to overcome this inconvenience we'll display the Edit menu and click on Preferences :
This way the Global Preferences window appears. With a clcik we'll activate the Detection tab :
To make sure the deteccion quality is as high as possible we'll pull the Pairs of Images sliding control to its maximum of 200 pairs. We'll also mark with a tick the Force all images to be part of the same panorama option. We'll keep the other options unchanged and click on Accept :
We'll try once again by launching a new detection :
The progress indicator shows the route :
At the end of the route once again the program has detected a panorama. The preview is too small for us to distinguish details. We'll open the edition window by clicking on Edit :
We can see this time there is no empty spot at the senith. The panorama stintching has been successful although there are details worth improving. The light blue marks are the program's watermarks indicating that the image has been stitched with a trial version. To get rid of them it is necessary to acquire an AutoPano-Pro license. one of the most evident problems is a certain lack of image aligning :
We'll click to make the vertical lines tool active :
With the help of a mouse we'll trace within the panorama lines which in the photographed space would match vertical lines. The higher the number of traced lines, the better the image remapping will be. To apply the tool's changes we'll click on the green tick :
We can see now that the panorama is better alinged. We can click to activate the tool which allows for rotating around any three axis on space :
To make the center of the empty wall coincide with the side extremes of the panorama we'll apply a 100 degree yaw. The minus sign before the figure indicates the rotation direction is from right to left. Once again, to apply the transformation we must click on the green tick :
Now the panorama looks well centered and we are satisfied with its edition. We can click on the Trace button to get the file creation started :
This way the trace window opens. On it we may decide the dimensions of the image, its quality, the file type, its location and type of compression, as well as other advanced options. It is convenient to mark Add a number to the filename to avoid over overwriting to be safe from accidentally deleting files created previously :
After clicking on Trace a new window opens named Panorama Tracer :
A progress indicator shows us the tracing process :
When the progression ends the file is already created :
We can find it at the location we had defined previously :
This is the aspect of the created panorama. Click on the image to see it as an interactive Virtual Tour :
Starting from the next page we'll see how to cover with a cap the empty spot at the nadir :
