General / 0.8.5 pre-release Alpha to Mask import issue

« on: January 26, 2012, 03:25:58 PM »

Hi guys,

Playing with the 0.8.5 pre-release, and I seem to longer be able to import a mask for the image via a photo's alpha channel.. I wrote a batch processor this end to detect blue/green screen backdrops that exports a TIFF image with alpha that acts as the masking information for PhotoScan. This has been working properly till this pre-release.

Unfortunately the console does not give me any feedback except to its finished

cheers

General / Re: Editing a ".tiff"'s EXIF meta data:: x,y,z heading pitch and roll

« on: August 01, 2011, 11:25:13 AM »

Also using Exiftool, and have created my own tool for batch processing masks adding an alpha channel to Tiffs. Mainly using Exiftool for adjusting the orientation of an image. Example I can give is as so::

exiftool -Orientation="Horizontal (normal)" podrot.tif

Breakdown of command line ::

exiftool    -TAGNAME="info to be used"    "name and location of file to update"

Orientation info used by exiftool ::

Horizontal (normal)   
Mirror horizontal
Rotate 180
Mirror vertical
Mirror horizontal and rotate 270 CW
Rotate 90 CW               
Mirror horizontal and rotate 90 CW
Rotate 270 CW   

All images produced by my setup have an initial orientation value 'Rotate 90 CW'. So I rotate the image and reset the orientation tag.

When it comes to adding/editing for Geotag metadata this should help ::

Example of editing GPS data without using a log file or a gui ::

http://techkr.blogspot.com/2007/02/write-gps-data-on-your-photos-with.html

Other tools to look at, if you're using Linux, are ::

exiftran (used for lossless translation of Jpeg images and setting orientation metadata)
exiv2 (used to export EXV/XMP metadata from Raw,Tiff and Jpeg images, then allows you to merge the metadata back to a given file)

all tools mentioned are available via your distro's synaptic or software installer.

Haven't looked at this post for a while... Just realized that there's an obvious question that wasn't asked....

Are you using a 32bit install of Ubuntu?

PS is for 64bit. The ")" output in terminal will happen if you try to start PS on 32bit Ubuntu distro.

Feature Requests / Re: Chunk visibility

« on: July 03, 2011, 09:18:23 PM »

How about each chunk is automatically assigned a new color making it easy to see in solid view. The corresponding color is also shown in the chunk list.

I find it really strange and disorientating that after aligning chunks, each chunks position when clicked on separately,  are not relative to the one set as reference. When you have a lot of chunks to trim and clean up, its really slows the pace of processing when you have to drag the view about the find the chunk you wish to edit.

Feature Requests / Re: Additional batch options

« on: June 28, 2011, 10:28:07 AM »

Along with the Align option, the ability to load a camera calibration to use for all chunks in batch list, and a tick box so the alpha channel is used to do masking hands free.

Written a nice little mask batch processor for Linux here. (could use photoshop back in windoze/sMac but want to stay within Linux. Its Just a shame there is no macro/actions function for the likes of gimp). My tool takes the photos, locks to a region & color you assign with a threshold limit, creates a binary mask, which can also be set to be feathered, then converts to Tiff with alpha and copies over the Exif data from its original to the new Tiff.

Also love to see the batch process give us more feedback as to what chunk its on and overall time for completion.

cheers guys

Its very simple.. first off there is no debian installer for PS, its a compressed file (tar.gz). Uncompress the file, by right clicking and selecting 'Extract Here'. When looking in the folder you'll find a file called 'photoscan.sh'. This is a simple bash script that acts as the executable to launch PS. Double click on the '.sh', and as long as its permissions are set to be executable, a selection of options will pop up, click 'run' and PS will launch.

Alternately, open a terminal, navigate to the folder and execute the '.sh' by typing   ./photoscan.sh   

This will allow you to see if there are any issues on launching.

hope this helps

Hi Alexey,

Have done as suggested, and its working perfectly, if a little slower. Hope the openCL is not to much of an issue to solve, or could it be related to the machine which is currently using a 8800GTX while I get the GTX480 replaced?

best regards

Feature Requests / Re: Progressive Alignment of Chunks

« on: June 23, 2011, 12:36:30 AM »

Also agree with suggestion. Just being able to lock chucks so they could be referenced for alignment would be great. I'd also like to suggest the ability to be able to translate and rotate an individual chuck for manual alignment.

cheers

Hi Alexy,

It seems to always crash, but random as to when. Just tried again and it crashed 10% into depth recon of first chunk. Have also reported this via the crash reporter.

I could send u the same data set, but I'm not sure the client would like this.

best regards

General / Quality of Merged Chunks

« on: June 21, 2011, 05:24:35 PM »

Hi there,

Having an issue with the final merged output and its quality. Should there be some sort of dialogue that pops up asking the likes of the detail, poly count and overlap reduction before it does the job?

The final output comes across a little too lacking in detail. 



best regards

Bug Reports / Batch Process Linux 64 build 985

« on: June 21, 2011, 05:01:44 PM »

Hi guys,

I've tried to use the batch processing on the Linux version. Went through setting up the chunks to be processed. Each chunk has masks applied to 8 images, an imported camera calibration and alignment points generated before doing a batch geometry build.

So i set off the batch process, and off it goes doing the first of what should be many depth reconstructions. It gets to the end of doing the first depth recon, and just sits there. Eventually, a good half hour after it got to 100% of the depth recon, I had to kill it.

any ideas?

best regards

Hi Alexey,

Just to say, have tested this function thoroughly on the latest build 985 and it's working brilliantly.

great fix

Bug Reports / Re: .obj imports with 0 faces

« on: June 14, 2011, 09:56:31 AM »

Also confirm 0 faces after importing .obj. Originally thought that it may of been related to the CG package I use for editing, but tried importing .obj's from Maya and Lightwave10.

Feature Requests / lasso tool for face selection

« on: June 13, 2011, 08:10:38 PM »

When it comes to cleaning up geometry created using 'smooth' method, I'd think a lasso tool for quick and easy selection of faces to be deleted would be a major bonus. Would also benefit from being only able to select faces that are visible in view, and not those that are back facing. Then for quick cleanup of any floaters, just use the 'select component' tool to finish up.

cheers

Mike
