General / Potree Alignment Isuue - SOLVED -
« on: December 28, 2014, 12:30:19 PM »
Hi,

I tried the new feature - exporting to a potree point-cloud (very cool to have this!). Only problem is I end up with a model with weird alignment -



The model WAS aligned in Photoscan before exporting, of course.

Thanks

---- update: ------

I got a mail from Markus Sch├╝tz developer of potree and he explained the problem, which was with the uploading of the file.

General / Question - How to Place Model at Point of Origin?
« on: August 03, 2014, 01:54:00 PM »
Hello

I'm looking for advice - using PhotoScan or any other software (meshlab?), what would be the easiest way to place a mesh at the point of origin (0, 0, 0)?

Exporting from Photoscan, the meshes always end-up at unexpected place.

Thanks

General / Exporting Matches
« on: May 09, 2014, 09:23:12 AM »
Hi,

I've seen this question here but no one answered, and I was wondering as well -

Is there any way to export the matching data?

Thanks

General / A Walk Through the Museum
« on: May 03, 2014, 12:26:03 PM »
Hi,

I wanted to share some of my latest work with PhotoScan. This isn't my first post, but it's the first time I'm showing some results.
Thanks to the newer version of PS I was able to finally create some models on my on (after some help from Wishgrater). I don't really understand the change (maybe someone can explain me) but finally I can create meshes (with medium dense point-cloud, and high quality meshes) at a reasonable time. Up until now I constrained myself to creating point-clouds only.
So here are some models I made while visiting the Israel Museum in Jerusalem. Shot with Canon 6D and 50mm (some models have missing parts because it was impossible to shot from that direction).
If you have any tips for me I would like to know... and questions as well.

Hello,

I would like to know, from your experience in this field, do you know of any Museums or Archives who operates a 3D scanning devision or unit, that works on bringing their entire collection into a 3D files archive?
Something like what the Smithsonian is doing: http://www.engadget.com/2013/05/14/smithsonian-3d-scan/

Thanks

General / Any fast way to align chunks?
« on: October 18, 2012, 01:21:50 AM »
Hello all

This is a little urgen for my school project for tomorrow.
This is my first experience with this software on large models.

I have 6 aligned chunks and need to align them together, but this is taking forever.
I thought this part of the process would be faster. It seems like the software is now aligning all the images together, as if the aligned chunks are not even taken into account?

Do you have any advice for me? Manual align somehow perhaps?

Thanks

General / Aligning Exterior and Interiors of a Full Building
« on: October 13, 2012, 01:18:38 PM »
Hello

I'm working right now on a preservation project through my academy, and i'm trying to use PhotoScan (just alignment, no model).


The place is the ruined arab village called "Lifta" near Jerusalem.

I made some alignment of several rooms and ruins, mostly from inside. I was wondering what would be the best procedure in order to align a full house together, including several room and the exterior.

Thanks

Tai

General / A challenge - aligning two scanned and cropped images, no exif
« on: September 24, 2012, 06:35:22 PM »
Hi Everyone

Before I begin describing what I wish to do let me just say - I am aware that PhotoScan was not made for these uses. Still, it is the best service that I've checked and was also quite successful at the task.

So, I have a collection of Stereographic imagery (actually it's from the Congress Library) and I want to align them and create a Point Cloud. (just alignment, no model for now)

The pair images were scanned together, so there has to be some cropping made, and there's no exif of course.

Still, despite these difficulties, out of many pairs of images I tried, two came out very successfully.
This is why I still have some hope that there might be a way to make the rest work.

Good - Cave https://dl.dropbox.com/u/8354036/photoscan/cave.psz

For original images - http://www.loc.gov/pictures/collection/matpc/item/mpc2004001009/PP/

Good - Alley https://dl.dropbox.com/u/8354036/photoscan/alley.psz

For original images - http://www.loc.gov/pictures/collection/matpc/item/mpc2004000976/PP/

The problem is that usually PhotoScan confuses and switches between the left and right images. The alignment works great - it's just the opposite way. The geometry is kind of "mirrored" but also deformed. I'm uploading some examples so you can see for yourselves.

If only I could tell PhotoScan - "it's Ok, just switch the images locations"! that would be great.

Bad - Street https://dl.dropbox.com/u/8354036/photoscan/street1.psz

For original images - http://www.loc.gov/pictures/collection/matpc/item/mpc2004000999/PP/

I know that this is a strange use for the software, but still, it did a good job on two of the images, so why not?

Does anyone has any ideas? it would make me so happy if this works...

Thanks

Tai

General / Rendering Point Cloud
« on: September 15, 2012, 10:14:49 PM »
Hello

I just bought myself a license of PhotoScan Standard and started playing around and exporting point cloud to various software.

I am looking for a way of creating a big-size rendering image of just the point cloud.
What would be the best software for the job? I tried Rhino and Cinema 4D, but it's not working or rather I'm doing something wrong.

Thanks

Tai
