Generating and displaying panorama images online

The software Autopano Giga 4.4.2 can generate Panoramas. You can get it here: https://hdrmaps.com/blog/autopano-giga-is-now-free/

The software uses the default settings to render a pano

From within the software, select File->Browse Folder, select your folder of folders of unstitched panograph images with "Recursive into subfolders" selected. If your source images are consistent in image count, set the minimum and average image counts to that. This software is designed for manual pano images, which can make it miss photos. Alas, if the software doesn't think a pano was done right, it will skip an image group all together. It can be hard to tell if a group was skipped. As far as I know, there is no way to tell the software to use a set of images from a known pattern in a certain way.

This will create a photo group on the left panel per folder. You can either select "Detect" on the image groups you want to stitch together, or hit the same green icon at the bottom of the window to detect all groups sequentially. This will create a preview pano for each photo set. Hitting the gear will open a render window with lots of settings. This step lets you queue up multiple pano images. The progress of this queue is visible in the Batch renderer window. Doing multiple renders with different settings, and comparing them with either image comparison software like Beyond Compare or opening the panos in pano viewing software can help you get better results.
