Yes, on two. I reverted back to 0.85 and it's ok.

With the new update (0.9) I was unable to export point cloud.

General / Re: Aligning Exterior and Interiors of a Full Building

I have only the standard edition.
Can't it be made by aligning several chunks? and if so, how exactly this works? do I need images correlating between the two chunks?

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

Olihar - that's amazing! I'm speechless, really.

But how does it looks from the side?
Could you send me those files?
And is there any way I could make this too?

Thanks again

Hi Olihar

That would be great, thanks!

I put two pairs here:
https://dl.dropbox.com/u/8354036/photoscan/00992.zip
and here
https://dl.dropbox.com/u/8354036/photoscan/00994.zip.

Is there a way to get this software too?

Olihar - Thanks, that's seems very interesting. I would dig into it soon enough

Alexey - That's great! It requires a bit of work but I already manage better results
Thank you very much!

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

Ok so I found a solution, but it's not the best.
Using Meshlab I was able to create a Capture, with the ability to "multiply" the screen size
Here's the result:


Still, if anyone knows a software that can show vertices,  I would appreciate your reply (going to check LightWave soon enough).

Method I've used to obtain the vertex points from a mesh created by PhotoScan.
1) Export the mesh from PhotoScan as a .obj file.
2) Import the .obj file into Rhino.
3) Extract the vertices of the mesh as points us the Rhino command ExtractPt. This can take a while.
4) Export the vertices in the desired format if they are to be used in other software.
I've used this method for meshes with several million vertices.

Hi David

I can get the vertices from simply exporting the Point Cloud and opening in Rhino (image attached).
But how can I render them into a JPG or TIFF? Controlling background and Point size would be great too.

Or maybe I totally misunderstood  what you were saying?

Hi Wishgranter...

I simply wish to export the point cloud for an image file. No professional purpose. Just something that I could print perhaps. Screen capture would be no good because I want to control the size and make it big.

As for creating MESH, it doesn't work very well for me. I've noticed PhotoScan is building a closed Geometry, is not suited for my captures. And anyway , I just need the Points. I'm not trying to achieve something very realistic here.

Thanks

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
