Hi all. This is a little urgent. I only have 2 days left in my evaluation! I have been reading the manual and trying to troubleshoot with the already-created forum posts. But I don't seem to be getting anywhere.
First, please observe this link to my project...
https://mega.co.nz/#!Q9BU0Q6b!rRO3YCUSL92td53dsbWpM3EnMrbSFPytnLUk0XD4yosIf anyone has the time/resources to help, I would greatly appreciate it.
Now, what I have in that dataset are photos of a movie theater that I was recently using for a screening. I wanted to model it. And so I took my Canon Rebel 550D and tripod to the theater. It was relatively dark. So I had to use long exposures and a shutter delay to remove vibration. My kit lens was set to full wide (18mm), manual focus, VR: 'off' and aperture priority (either f8 or 11). I let the camera pick exposure. The results came out okay. I think the ISO was set a little higher than I would've liked. But all in all, I could live with it.
Chunk 1 has the pics from the front of the theater (closest to screen, pointing to the rear). Chunk 2 has the reverse of that (rear of theater, pointing to the screen). There are probably another 200 photos taken from the sides and from other vantage points (which were excluded due to size)... I am able to align the images in the chunks to what I would assume is a relatively high degree of accuracy (thanks marcel
http://www.agisoft.com/forum/index.php?topic=3559.0). I am able to render out the point clouds and am happy with the results. But where I seem to be needing assistance is with the alignment and merging of chunks. I assume that aligning the chunks is a prerequisite before merging. So I align them w/ a Point Based method, high accuracy and the default 40,000 point limit. Chunk 1 is referenced... I merge the chunks based off of the dense point clouds. The process happens very quickly and I'm left w/ a merged chunk. It contains all 55 cameras, w/ 52 of them aligned (I disabled 3 of them). There are tie points and a dense cloud. However, the points and cloud are only from Chunk 1. And I believe that the cameras are not aligned as a whole. But rather as 2 sets.
My earlier attempts included using markers for both chunks. As a side note: the ray plotting is very accurate, out of the box. And it only seems to get better, as you refine the positions... I used the same marker names for the corresponding points on the 'front' photos and 'rear' photos. However, that didn't seem to help very much w/ alignment. As far as I can tell, 'aligning' chunks isn't doing anything other than place an [R] next to a chunk. Ultimately, I know that I'm doing something wrong... I'm also hesitant to use markers, as they're not available on the standard version.
So at this point, I'm at a loss. You can see, in my project, that I've taken it to the point where I've created both chunks. And on their own, they seem fine. What I would finally like to do is figure out how to align most, if not all, of the cameras and then to create a DSM from them. It's a tricky project because the photos from the sides of the theater look almost exactly alike. And when I though that Pscan would just magically create this model for me, I fed it all 220 photographs. And what came out of the other end, 13 hours later, would not be considered anything more than abstract computer art
If anyone w/ the standard version could especially chime in, I would appreciate it. For a hobbyist, the cost of the professional version forces me to look at other options (Pmodeler Scanner being the next area of focus). It would be nice, if there was a $1500-2k 'prosumer' feature set.
Lastly, I'm running this on a custom-built PC w/ the specs: i5 4670K, 8GB memory, 2x AMD R9 290 GPUs. Outside of the memory limitation, the software performs well. So upgrading the memory is not a problem. I'm looking at replacing the CPU, motherboard and memory though. Anandtech's Haswell-e review leads me to think that the mid-range chip might be a sweet spot for price/performance. If anyone thinks otherwise, please let me know.
Thank you for reading.

Interestingly, the problem now must be a scale issue. I created a third chunk and aligned a set of photos that travel along the 'stage right' side of the theater. Surprisingly, Pscan was able to line them all up! But there seems to be a new issue...
