Feature Requests / Re: Automatic Masking.
« on: May 03, 2012, 08:54:40 PM »
Your idea sounds smart and I'd like to have a tool for this too, but having said that, I find this request too much focused on an specific need which may not be of general use. I guess it could be done outside (Photoshop macro could fit) if you managed to generate mask files suitable to be imported into Photoscan project and applied to photos by means of scripting.



Feature Requests / Various wishes

1st. a happy new year

2. Standard views for the model(top, down, front, back, left, right) plus "car mode" option for the last four ones (that means +z pointing up).
I'd suggest to allow it by rightclick on model tab and also shortcuts like caps+F1 to F6

3. Customizable grid lines to be seen onto standard ortho views and as a switchable option in orthophoto export.

4. Model colour scale view mode.
5.  ;D I dont like soccer very much, so why not to use a colourful balloon with agisoft's logo as icon for textured model view mode
6. allow chunk lock (anchoring) and add a split-view interface for image-based 3 point picking during chunk's alingnment as a more efficient way to get the initial guess and then launch whatever you are using to get them aligned (ICP?)... I'll be pleased to explain myself further if you liked

one bug: When you are editing one marker in an image, and want to delete it (the marker) by right-click on its corresponding branch on the workspace tree, the program asks if one wants to delete the actual image instead of the marker. If user do not realize (as likely will happen), the consequence is an irreversible image deletion.

regards and +++ congratulations,

Bug Reports / Can't export orthophoto
« on: July 29, 2011, 07:14:05 PM »
I've built a model from six aerial images, everything has gone as usual but when i wanted to export an orthophoto, a popup simply warns "Can't export orthophoto". Any hint?


Bug Reports / Re: large numbers

Yes, of course:
My ground coordinates are something close to 462000,4628000,900
Y created a file for the GCP as follows

<?xml version="1.0" encoding="UTF-8"?>
<keypoints coordinates="local" units="meters">
<marker name="point 1">
<marker name="point 2">
<marker name="point 3">
<marker name="point 4">

So I imported them and calculated with final residuals being arround 22cm
I then exported orthophoto with 0.05m/pix as aimed resolution resulting in what I called ugly ortho :P
Then I simply changed coordinates by substracting 462000, 4628000, 900 and tried the same ortho... the results are better looking now. Have a look before after

Bug Reports / large numbers

Hi, folks
I've found that ground coordinate system with long figures (ie. 123456.789, 1234567.890, 123.456) but set as local system make PS to generate ugly orthophotos.
I guess it might be related to a loss of precission associated to rounding numbers.
I'd suggest to PS team to declare a huge translation variable to shorten numbers during input and restore them to long during output.

I'll give a try

General / Re: Way to follow with a white model?
« on: May 05, 2011, 04:16:26 PM »
White objects are allways challenging but also those with flat colours or poor texture.
I've had some success (but with different programs) by projecting a rich texture onto white object by means of one or two lcd projectors during shots. A dense text is a good texture to try with.
Take two shots from each camera pose, so you can have the same picture with and without artificial texture (make sure you don't move the projectors during photograps) .
I dont think Photoscan keeps needing texture once you have oriented photos and created model, so it should work if you simply rename untextured photos to the same names as textured ones and apply clean photos to your model. Share your results if worked.
