Welcome to the forum...
I use a microprocessor-controlled 360 mount which creates an accurate digital output for elevation and azimuth for each image. This data can either be incorporated into the EXIF header of each image or saved a XML file or put into any other format as required. Is it possible to import this data into Autopano to improve the accuracy of the panorama stitch in the same way that Papywizard does?
Yes, if you put the data into the format required.
