Well done! Which software do you have used in the movie for editing the mesh?

@Wishgranter: No problems with viewing on Windows 7 and firefox or opera.

I see three advantages to project a pattern with a flash in comparison to a projector:

1. higher portability (no power cable, smaller, lighter, ...)
2. brighter
3. higher resolution of slides -> higher resolution of the calculated geometry

The ratio between camera stereo base and distance to the object should be in the range of 1:5 to 1:10 for good stereo model.

Another option for focus stacking is to use Magic Lantern for Canon DSLR's or CHDK/SDM for Canon's point and shoot cameras together with one of the free image stacker (Enblend, Tufuse, Picolay, ...) .

Cheers,

Hi FoodMan,

yes, I have the stable release v2.3 from 2012 on my Canon 60D, really stable, no crashes, funny new features and definitively worth a try.

Camera Calibration / Re: Undistort Photos

Yes and aligning is time consuming too. Or the possibility to undistort images within Photoscan based on camera calibration results without prior aligning.

Thanks!

Ludwig, Cotopaxi,

nice if you post the coordinates of the GCP's, so we can try (the original offer to test it in Graticule 3D came from Ralph btw., but Graticule 3D is really funny - so no problem to test it for you or you do it by yourselve)!

Btw. snow is one of the worst subjects to scan in near makro mode when you can see the crystals, the far away the better. I have tried it only once.

Good luck with testing the suggestions!

Regards,

Karsten

Ralph,

Yes I also think that the errors given in the screenshot show the dicrepancy to the model that all GCP's have the same z value (zero). Thats why I thought it isn't right to set them all to zero, because they couldn't have the same value. I think Photoscan try to find the best solution for the given (wrong) GCP's.

Regards,

Karsten

Hello Ludwig,

if I understand you right, you want an ortogonal photo of the area of slope. So all your GCP's can't have a  z-value equal to zero, which means a perfect plane. I think you should at first do a plane fitting for your GCP's for example with "Graticule 3D" http://derletztekick.com/software/formanalyse. Then you get the right z values, which are slightly different to zero. These values should be used in Photoscan.

Regards,

Karsten

« on: March 07, 2013, 07:50:19 PM »

trzs,

in principle: Yes mirrors could be used, but you lose image resolution (two mirrors -> half resolution, ...) and you have some work by hand (masking, duplicating, ...). The simplest way is to use a beamsplitter.

Hi RalfH,

I think you get some answers to your questions in this paper "IMAGE ACQUISITION AND MODEL SELECTION FOR MULTI-VIEW STEREO" by K. Wenzel, M. Rothermel, D. Fritsch, N. Haala:

Thanks Agisoft, that sounds very promising!!! Why is that not mentioned in the changelog?
