Python Scripting / Re: Scale a model / Accuracy / multiple sizes
« on: August 30, 2019, 03:51:24 PM »
Dear Alexey,
as always - you are right - I can do that manually and the calculated length is correct. But for me the problem still exists:

I can not use the GUI - I have to use python console.

This is part of the script I am using:
import PhotoScan
chunk =[0]
for m in chunk.markers:
      print (str(m.label))
      m.reference.enabled = 0
   except Exception as e:
for sbs in chunk.scalebars:
   print (str(sbs))
   sbs.reference.distance = 300
   sbs.reference.accuracy = 0.00001


And get an Output:

2019-08-30 14:44:48 target 1
2019-08-30 14:44:48 'PhotoScan.Marker.Reference' object attribute 'enabled' is read-only

2019-08-30 14:44:48 <Scalebar 'target 1_target 2'>

(I use Photoscan 1.4.3 - 6529 & Win10)

Python Scripting / Scale a model / Accuracy / multiple sizes
« on: August 16, 2019, 12:10:38 PM »
My task is to export models in different scales / sizes as some programs, my clients are using, are not configurable with regard to the import units. A model that has 30cm in Agisoft is very small (factor 1000) compared to models created with other software. I know that OBJ and other fileformats do not contain any information regarding the units (Meters, cm, mm, inch....) and that the interpretation has to be done within the 3D software that is importing.

To help my client, importing 3D models from different programs in same sizes/scales, I want to export the created model in different "scales". I use markers and scalebars to size the model automatically and it works perfect. See picture 30cm.jpg.

My idea was to change the definied distance of the scalebar from 0.3 Meters to 300 Meters and have the same model - just larger by factor 1000. Basically that works - but it is not scaled by factor 1000 - it has deviations as visible in picture 300m.jpg. A former distance from approx. 19 cm becomes 18.6 cm. I expect that it comes from accuracy and that the error will multiply, when changing scales.

Is there any other way to scale a model *exacty* by factor 1000? And no - it is not possible to do this during the import into the other software - it does not contain any feature / configuration to set the units.

Thank you - Christian

fengkan - the raspberry cams and the pi are network devices with simple chips - they are not usable "out of the box" you have to tweak a lot and my solution was, writing my own code to "control" the camera module. You should know what you are doing, using such a development environment.

But once you make it, the results are great for such divices.... see attachment - this are the photoscan results without any tweaking with zBrush or other tools. Purely photoscan...

And... if you do not want to go through all that pain - why don't you just buy one ready to operate solution from me  ??? - we sell our 3D-APPARAT as a turn key solution with 1,6 x 1,6 x 2,25 Meters footprint including 150 cameras and a tablet to operate the system secure and easily for only 25.000€ (plus VAT)... /

@wishgranter: I am also in that Full Body Scanning and Printing business...

We are just releasing our first Full Body Scanner that is exactly made with the intention "everybody" is asking for (OK - not you Exhale...) . A fully automated process... The result is our 3D-APPARAT (please do not visit the webpage at this time - we invest all time in the setup of the machine and the processes behind them). Here is a first preview of the system:

The pictures are uploaded automatically to our file servers. From there we have to select the folder in PS and have the usual steps been done by PS (at this time without masking to save computing time...) . It would be perfect to have that in a batch process without a GUI and a user that has to click and point as we always have to do the same steps and have somebody watching the screen to initiate the next step... should be better done by a computer - but that is up to Agisoft.
The generated mesh is uploaded to a folder where a meshlabserver process is waiting for it to smooth it (automatically) with one filter setting and upload it back to a PS folder where a (again) human has to load it back to PS to generate the texture.

That's all... and the results are at this stage (without any zBrushing or similar) look like this: (and the 3D-APPARAT will be sold for approx. 20.000€ - please have that in mind, comparing with other solutions...)

This results are ONLY thought for 3D printing in a scale up to 1:10! Nothing more or else. Even the small spikes will not be visible in the 3D printing (even though they will be eliminated later...) We know that scans can be of higher quality - but they are needed for different applications! It's like driving a Formular 1 car in a town - doesn't make sense as it is made for a different application....

You are right, Lee (and Exhale) - quality is key, you know it better than most of us and for your application it is more than true. But for the grandparents that want to put their grandchilds on their chimney, "future is now" and the next scan will be done next year. Within this time everything will be improved - as I wrote - everything depends on the application.

Is somebody of you willing to upload models (full body scans) with the same stage of "no zBrushing"? I really would be interested in seeing other non-clear / non-makeup results.

Thank you!

As we are looking for some new machines I appriciate your work and all updates regarding new results.

BTW - did someone try photoscan on the new Mac Pro?

@mala - the RaspberryPI is a network device - this means - downloading and managing is implemented by it's roots. It is really the other way round - you have all the possibilities with sync and timing - but have lack of optical system... we all do have our challenges  ;-)
Using RaspberryPI AND real Cameras is the perfect world - but who want's to live in a perfect world?

Yes.... They are Raspberries...

we planned to use Canons - but we did not want to run into too many syncronizing problems. Therefore - and as our background is tcp/ip networking and other it stuff - we decided to have something "controlable" within our hands. Raspberry PI is (beneath Arduino and similar) a good solution for that... then we decided just to add some camera modules to have some fancy 3D HD video as a add on.... well that was the day we decided to go a completly other way and focus on the cameras and build a "cheap" 3D photo booth...

COOL! With 0.0014 x 0.0014 it works as expected!

Seems like an "beginners mistake" - I hope that I haven't distrubed too much and maybe some other beginners learned a lesson ;-)

Thank you all!

Of course - the camera is a Omnivision OV5647 (

Pixel size should be 1.4 x 1.4 µm...

and no - i have not been entering it into my config - I even have not thought about it... sorry. Will try that and do that NOW....

@Andreas: Thank you for your input - yes - this will help after the complete setup to have reliable and repeatable scans. We will do that. Thank you. The main problem at this stage is that if you put 25 photos inside the workflow everything is fine - if you add just one "not alignable" photo, even the other 25 cameras are not correct anymore..

@Alexey - Of course, I will send you the dataset - I will contact you with a private message to get details where to send to.

@All: Just to make sure to point this out: I am aware that we are using VERY poor quality pictures and we are working at the edge of the possibilities. Sometimes we have less than 8000 detected points to be matched. The model is based only upon a few more than 3000 points.... I know that better cameras (better pictures) will solve all problems. But this is not the point at this moment - my problem is that the program works perfectly until there are some "bad" pictures inside - beside of sorting them out/dropping them, everything breaks...

I am currently setting up a full body scanner using inexpensive 5MP camera modules. I am not looking for a perfect 1:1 scale usage of the models - models will be later printed out between 2 cm (!) and 20cm - I do not need all details - even though I love the work of INFINITE/LEE. Thank you for all inspirations!

This setup and quality works fine and the results are promising. Today we are setting up 40 cameras for 180 degree - I expect that we end up with 100 cameras (total material cost of that full body scanner will be less than 10.000€). Plan is to roll out some hundrets of that 3D photo booths around the world  :)

My question / problem is:

If I use the first setup up pictures (27 pcs) at once (load all into PS) and then apply a background mask, PS is not able to align the photos (Attchment 1). The cameras are completly wrong orientated. If use chunks (also with applied background mask) and put inside the first 8 pictures (head) - all pictures are alligned perfectly. If I put another 4 to that "working" chunk, again fine - photos are alingned (attachment 2). This works perfectly until some photos are not alignable (in our case the feet where the cameras are not set up perfectly at this time...) (attachment 3).

How can we solve that problem that we first have to detect the "distroying" pictures and than can build a model? I would love to put all photos inside and get the non alignable photos sorted out - but why are the photos that can obviously be aligned perfectly also disorientiated??

Any comment welcome...
