Is there a way to replace the final texture atlas? If so, you could grab two images with the cam on the same position. One with pattern to get the depth, the other (simple white projection) to get a good texture (if needed).

Edit: I thought of a way replacing the texture within Photoscan (sure ZB or other apps give that option)

You may also consider a colored noise image. Seems you can get even better results. Although I've to fight against color issues caused by my DLP projector :roll:

Gunter that was my next step.To use colored noise pattern.
I will try to scan a head statue and i will post my results as soon as i have some.

Hi everyone,

thank you for posting on this thread.

My interests is what I can do IF I cannot get my subject to my scanner.......are any of these options viable.

Photoscan seems to do a good Job, and the software was inexpensive.......there is another option out there from California....

www.Visualsize.com

It is only in beta testing.....no user upload to the cloud yet.....but it should be soon.......very dense pointclouds and meshes...here is a result of the same sock foot I was testing....

with "socks" there can be a very dense pattern inherent in the design, so it is easy to get gross geo-data from something like these systems without the noise patterns...

the actual mesh it generated was better than this video shows....

AgiSoft also have something called StereoScan, and it's free. If you take a stereo pair, it might be able to build a model like this. I've had some great results with it. One of the nice things, is that it gives you image-relative UV coords (left image). This means that you could actually get a full-color texture, by taking a third picture in the same location as the left image. You then can just simply swap the active image to the colored image, and you have a full-color texture :)

Here's a result I got from two photos from a Canon 5D MK II using StereoScan.

Hi FotoscanDavidias
Very useful result . For me not yet detail rich .
Tibor


The hardware write about a solution . How large the distance of the two uptakes was. Did you use a rack?

In order to have good results your objects must have textures so the software can pick random matching points for reconstruction.
Both your statues are almost white with no distinctive pattern.Use a noise projection image and then take the photos.You will have much better results.
Of-course you cant have the great results of laser or structured light scanning like David has.

Another test using images from photomodeler scanner demo version.
Reconstruction was done with StereoScan(Agisoft).
You will see 2 different results.The first(left scan) was done with the images at default resolution.
The second(right scan) was done with the images scaled 4x.Huge difference on details.
Off-course its not the correct way to do it(i mean the upscale) but seems it works.

So you just scaled up the images to get that much more detail? Interesting...

Hi

I ask this in detail to outline .

Hi Davidias FotoDigi
I did the comparative test. His result : 0.03 millimetre standard deviations .

Hi Agisoft
What is the distance between the two uptakes. The distance of a camera between the two pictures .???
