General / GCP questions:

« on: January 19, 2017, 05:17:57 PM »

1:  the checkbox left  to a marker (to left for "long,lat,alt,accuracy,error"...)    - does it enable/disable a given GCP for processing ?

2: if there is a marker, (GCP) , but it is not placed in any photo ( "it's icon is not green, but grey")  does it have any influence on the processing ?

3: is it possible to have a marker only be used for altitude only ? (aka - the position is +/- 10meters, but we know that flat area had a given altitude of xx.xxx meters)

4: imagine all photos for a map contain ellipsoid (GPS) altitude, then we add some GCP's with local geoid corrected altitude, - is the result expected to be "good" ?  - or does all altitudes, (in exif too)  - need to be geoide corrected ?

Feature Requests / Batch requests: two simple requests that would improve functionality,

« on: November 16, 2016, 08:19:49 PM »

1: please add an action "create directory"
before exporting tiled data, it would be very nice to be able to
mkdir {projectfolder}/Tiledoutput

2: please add "enable/disable" checkbox per script action
When using complex scripts that are supposed to do a lot, from start to end, - you may sometimes do something, or want to do something manually.   
So it would be very useful if we could just disable (skip) steps , without altering the script.

General / Is batch with relative paths/names possible ?

« on: November 16, 2016, 04:04:08 PM »

my projects are usually in own folder:
~/photoscan projects/placename/placename.psx

making a batch that ends with multiple exports, is hard, because every export needs it's path, like:
import photos from:
~/photoscan projects/placename/photos/*
export:
~/photoscan projects/placename/placename-orto/placename-orto.tiff
~/photoscan projects/placename/placename-dem/placename-dem.tiff
~/photoscan projects/placename/placename-las/placename.las

I miss the possibility to script something like:
# %pname% is the name of .psx file
# %ppath% is the path of the .psx file

import:
%ppath%/photos/*
export:
%ppath%/%pname%-orto/%pname%-orto.tiff
%pname%/%pname%-dem/%pname%-dem.tiff
%pname%/%pname%-las/%pname%.las


This way . a script would be perfectly re-usable between projects.
this way - the same batch could be used on every dataset, and

General / ubuntu 16.10 : error while loading shared libraries: libpng12.so.0:

« on: October 14, 2016, 01:50:46 AM »

an attempt to load w/o the .sh file shows that:
$ ldd ./photoscan |grep png
   libpng16.so.16 => /usr/lib/x86_64-linux-gnu/libpng16.so.16 (0x00007f2394b10000)


and
$ ./photoscan
./photoscan: error while loading shared libraries: libcholmod.so:

executing the .sh file gives the error in subject.

Feature Requests / "Surface extraction"

« on: August 04, 2016, 12:17:50 PM »

Is there a feature that can rutomatically remove objects/trees from DEM data ?

Bug Reports / Import reference data in other coordinate system than WGS84 fails.

« on: August 02, 2016, 03:10:10 PM »

If I add a csv containing EPSG::25833 markers ,selecting in the import dialog that coordinate system, it will show up in the marker list, but *no* markers will be in the map correct area.

If I convert the .csv markers to ESPG::4326, using gdaltransform, then import it as EPSG::4326  - it'll work properly.

Somehow, "Import CSV" dialog - does not really treat the coordinates as EPSG::25833.

General / Which steps in workflow needs to be re-done after adding GCP's ?

« on: August 02, 2016, 03:03:33 PM »

I have rendered some maps.
Then added more GCP's. (and placed them in photos)

-which steps in the workflow need to be redone ?

General / Q about multi-level flights.

« on: June 27, 2016, 12:03:00 AM »

Imagine a dataset consisting of photos with 60% overlap,  *and* photos with barely any overlap,(lower altitude).

Question: Will the closer to the ground photos still be used to give good details because they can be aligned using the higher-altitude photos ?   - will the map be better ?

General / Question about adding GCP to an "completed"

« on: June 26, 2016, 11:59:13 PM »

I have made some maps w/o GCP  - now I got GCP's.
how far back in the workflow do I need to go (what to repeat), in order to properly render it with GCP ?

Feature Requests / Please post application icon.

« on: April 19, 2016, 11:13:11 PM »

The application does have an icon, but please post a .svg , .png or other icon , and make it a standard part of the linux package,  That would make it easier adding a nice shortcut to the application.

Feature Requests / Please make batch processing display time spent per step

« on: April 15, 2016, 01:49:50 PM »

Please add information about time use for completed steps like:

"Dense Cloud...  completed in 1h23m"

Feature Requests / Report time.

« on: April 15, 2016, 01:47:49 PM »

Hi,
The Report provides a big time/date of the report time on the first page.
It would be nice if also checked EXIF when available, and said:

Data collected  20/4/2015 09:40  ..  12:30

giving a clue on when this job was done

General / Photo Alignment - manually trigged alignment can do more.. - why ?

« on: April 15, 2016, 01:39:29 PM »

Why is it so, that when "Align photos" step is done, it's still possible to get some more photos aligned, just by selecting them and clicking ~"align photo" ?

Why is that not done automatically ?

Bug Reports / Processed a map, but unable to export to tiff/bigtiff (PhotoScanPro1.2.4)

« on: April 15, 2016, 01:28:01 PM »

Please see photos, zooming in helps with more details about the map. (sorry for not taking screenshots, but I wanted the process to be as uninterrupted as possible)
Efter selecting to export as tiff og bigtiff, all RAM is hogged - then swapping to a fast 160GB SSD starts, ultimately it will be full, and the process fails.

Why ? - as I understand it, the data is already there, and it's just a matter of writing it to a file.
The whole dataset, with pictures and all the processed data, is only 40GB

Feature Requests / Please optimize geotif export

« on: December 19, 2015, 02:00:41 AM »

I can export geotif of huge/hires areas as tiles just fine.
- exporting to one .tif file file fails - it's "never" enough RAM for that.
please consider writing a tiled geotif - processing it as tiles, or export to tiles, then assemble to one big tif (in case that reduces the needed RAM)

I have 64GB RAM on Linux, with 96GB SSD Swap (which never gets close to filled anyway)
