Hello! I've used Hugin in the past with pretty good success to create 360x180 panoramas but recently I've been having performance problems.
I'll start with system info: - Windows 7 Home Premium 64-bit SP1 - CPU Intel i7 2600K - 8GB RAM - Video Card 1GB ATI AMD Radeon HD 6700 (not sure if this is relevant) - Hugin version 2013.0.0.0d404a7088e6 In one situation I'm shooting a fairly large interior space, +/- 2 bracketed, using a Panosaurus 2.0 tripod head. I've loaded my 55 images into Hugin (yes 55, I've already masked off the tripod in the nadir shot in Photoshop and don't feel like I need the other two exposures), masked of some areas, and used autopano-sift-c on different selections of photos to create control points. I then aligned and it worked fine but wasn't perfect so I manually modified control points, optimized position/view/barrel, and went to align but it is taking quite a while. It is definitely running because autooptimiser.exe is consuming a full CPU so it hasn't frozen. The Optimizing Variables iterations are chugging right now at the 28th iteration but each iteration seems to take about twice as long as the last with the last taking 15-20 minutes. The Average (rms) distance of iteration 27 was 1.43535468375691 and iteration 28 moved just to 1.43510034667803 so it isn't really doing much any longer. I have 1526 total control points with mean error of 2.35 pixels and max 80.17. Something to note is that before optimizing position/view/barrel I optimized using the Positions (incremental, starting from anchor) option and Hugin crashed. I reloaded the pto and the position/view/barrel option ran fine. Another series of shots that I was processing over the weekend I let run for over 30 hours and it still hadn't finished so I killed it and scrapped that series of photos (at least for now). Does anyone have thoughts on what could cause this? Could my configuration be screwy? What causes Optimize Variables to stop? Is it a set number of iterations? Is there a way to make it stop after less than 1/100th of a unit changes between iterations or something?
