General / Re: Missing "stripes" in orthomosaic
« on: Today at 06:46:18 PM »
Hello James,

Can you send the project in PSZ format with the alignment results and imported mesh to support@agisoft.com (or via PM), so that we could check what causes such behavior?

Original images are not required.

Hello Michael,

Currently PhotoScan doesn't support exterior and interior orientation estimation based on the set of the reference points.

Using the scripting, however, it would be possible to assign the proper camera location and orientation to the single image if you already know this information from other source (either orientation angles and XYZ coordinates or full transformation matrix is required).

Hello James,

There's a "tweak" for advanced settings called "main/ortho_expansion_limit" that defines how bigger than the source image is the orthorectified output could be. The default value is 2, so for the low-resolution imagery you can increase this value. However, I recommend to set it back to default to avoid possible memory consumption issues with the common imagery later.

Hello Caetano,

Which import formats are accepted by NavisWorks?

Also are you selecting "Save Colors" option when exporting the point cloud from PhotoScan?

Hello LilC,

To fix the problem with the coordinate system you can use Local Coordinates option during export (if the chunk is originally referenced in the geographic coordinate system), or use SHIFT fields to subtract large values (like millions and thousands of meters that are the same for all the vertices), when exporting in the projected coordinate system.

General / Re: Agisoft - Export DEM
« on: October 21, 2018, 07:23:50 PM »
Hello caleiro,

I suggest to use the Raster Transform -> Palette option in the Export DEM dialog to save only RGB picture of the elevation model without embed elevation information (like in GeoTIFF). JPG format doesn't support floating point information, so if you use this format without the raster transformation enabled during the export, you wouldn't get proper output.

Can we get some information about the auto classification being used?  I ran a quick dataset through it and recieved very poor results.  It seems strange to me that I am getting these results when I am using a very clean dataset. 
Photos have 90% overlap shot at 100m agl as 20mp.  I classified the dataset using the old tools in version 1.3 and was able to get very good results in a short period of time.  I was hoping that the autoclassification would at least get close, but my results are extremely bad.  Could I be missing something?  I should add that I am running the 1.5 pro beta as a demo right now.

Hello SuperNewb,

The new classification option is based on the machine learning, so if you are observing unsatisfying results, we would like to ask you to send the point cloud that you are working on to support@agisoft.com (just point cloud exported from the project will be fine, just keep the source coordinate system and point colors).

Most times the "Refine Seamlines" option leads to holes in the orthomosaic while no holes appear if the option is switched off. Analysing seamlines from both options, it's notorious that a much better result is produced with this new option. Mosaic tends to be a lot better without too much jagged limits on objects. However if holes are produced, it will be a lot less interesting to use.
Hello RHenriques,

If there's any sample set of images that can be used to reproduce the problems with the orthomosaic stitching (e.g. holes in the mosaic), please also send the data to support@agisoft.com, so that we could analyze the source of the issue and fix it.

with latest release, I retried orthorectifying with refine Seamlines options. It works now without setting the Fine level in Network options....

However it still does not give satisfying results with seam lines passing thru buildings (marked in red on screen shot).

Also, the OrthoMosaic was done on a small region (shown in model view).

However, the ortho shows an extent of 37928 by 25257 pix at 7cm/pix which does not correspond to the extent of region … It corresponds to full extent of model...
Hello Paulo,

Would it be possible to send the project files (alignment results + DTM + source images) that we can use for testing the seamlines refinement issue and extent problems? If so, please send the download link to support@agisoft.com and mention this thread in the message body.

As for the connection to the cloud problems, then is there a proxy server used on your side?

Hello Chris,

We will send to you special version of PhotoScan that utilized OpenCL instead of CUDA for NVIDIA graphic cards, as it seems that at the moment installation of CUDA drivers for Mac OS X does not solve the problem as usual.

« on: October 18, 2018, 12:35:15 AM »
Hello stefwill,

If you are using the latest version of PhotoScan Pro, then you can define To WGS84 parameters in the Datum Transformation section dialog (the corresponding button is available next to the coordinate system selection dialog).

These parameters are used if the coordinate transformation should be performed between the coordinate systems that are basing on the different datums.

Hello trananht1612,

Can you please check that you haven't mixed Latitude and Longitude values when georeferencing the model in PhotoScan?

For the coordinate system you can use WGS84 or WGS84+EGM96 height.

Hello abbey146,

Is it possible to send the project re-saved in PSZ file that contains the described data to support@agisoft.com?

Hello abbey146,

Do you have the coordinate information loaded both for cameras and markers to the Reference pane?

Do the selected coordinate systems in the Reference pane settings dialog correspond to the real systems for cameras/markers properly?
