Thanks Igor, do you happen to have a good staple of fixed lenses that you usually use?  Also, and this may be a terribly silly question, but what features would I use on the 7100?  I am very much still a novice, but I this is something that I want to pursue due to the lack of this service in my area.

Nikkor Macro 60 produced good result for me. I guess you should look for good macro lenses, they are disigned to make sharp images.

To make any meaningful working, I do need external 220V power supply. Nothing serious can be done running on battery.

Okay, that's what I've expected. I thought I could missing something. Should I get a descent videocard, I'll try to find an USB PCI raiser and check productivity, just to know it for future and share with people here.

General / USB accelerators?

Hello

are there any USB accelerators usable with PhotoScan? I can imagine USB PCI raiser card and a video card in it, with USB 3.0 there can be some speedup, but maybe I can find something more specific?

Maybe some USB bitcoin miners can work with photos?

Minimum ISO is 200 on Nikon D300s; I have "low -0.5" and "low -1", but they does not seem any useful.

I've tried to make shots from three different heights and shift about 1 meter side on each set. I do understand about different position for each shot, but I cannot get closer to tank due to the fence.

Right now, passable quality of mesh has been achieved. I have now (a) find more, much more hardware for dast processing and (b) find a tool/develop a procedure to make good model from mesh.

And I do need a crane for shooting top. But it's not a matter for this forum.

Thank you and wish me good luck and purchasing of a PhotoScan soon

Looks like I've managed it!

My notebook can process only a little model in finite time, but quality seems to be passable.

Maybe someone can make some suggestions on improving quality?

I don't think google does something transparent with my files. I'll try to redevelop all files manualy

Will saving as tiff help? I've tried to save with 100 quality jpeg and do not see much difference. Maybe I'm doing something wrong in Lightroom/Photoshop?

So two of GTX 580 should outperform one GTX 780 for the same price?

I've suddenly run into strange alignment problems.

I've limited model to front details of tank, since I have only 16 Gb of RAM and cannot install more in my present notebook.

project t34front

Some photos - MANY photos - are not getting aligned.

What can I do to fix the problem? More photos? From which points? Maybe some hint to PhotoScan, to help it place photos in correct places?

First of all, I need more RAM (yes, I do have it now).

I had a quick play with some of the images. In general I'd say that the camera angle tends to jump around a bit, and in some cases there aren't really enough images to provide adequate information of the detail of the tank that you focused on.  I'd suggest trying to be more methodical in your approach to taking the images. Whilst it's not entirely necessary, it helps when you're starting out to have each image overlap part of the previous image. Focus on getting an overall set of images for the tank and then move in on specific details and you should find it easier to get a good result.

You see, there was one thing more important to me than making good shots: not to fall off tank or pedestal. Quality of resulting 3D model would be too low in that case.

And I'll print markers on soft magnets, it must be great for tank shooting.

General / Re: Licensing for network processing

« on: March 10, 2015, 04:48:08 PM »

Currently each computer involved in network processing (either in server or node mode) requires PhotoScan Pro to be installed and activated with the separate license.

... which render all the idea 100% unusable for me. Okay, I think I'll do a try with trial, just to see if I'll be able to improve performance.

Okay, here is a part of tank processed with medium quality. I'm expecting 8 Gb more RAM today.

Hello

It's unclear from manual if I have to purchase a license for every processing server or just for client node controlling the process?
