Hello,
I would like to use panotools to stitch a photo-mosaic in batch mode. The information that I use is from here: *http://wiki.panotools.org/Stitching_a_photo-mosaic* <http://wiki.panotools.org/Stitching_a_photo-mosaic> *http://hugin.sourceforge.net/tutorials/scans/en.shtml* <http://hugin.sourceforge.net/tutorials/scans/en.shtml> *http://hugin.sourceforge.net/tutorials/Mosaic-mode/en.shtml* <http://hugin.sourceforge.net/tutorials/Mosaic-mode/en.shtml> (and so on) First I create a batch file that automated the process for a 5x5 mosaic: @ECHO OFF @SET IMAGES=T??.tif @SET PREFIX=Test @SET HUGIN=c:\Program Files (x86)\Hugin\bin @"%HUGIN%\pto_gen.exe" --projection=0 --fov=5 -o project.pto %IMAGES% @"%HUGIN%\pto_lensstack.exe" -o project1.pto --new-lens i1,i2,i3,i4,i5,i6,i7 ,i8,i9,i10,i11,i12,i13,i14,i15,i16,i17,i18,i19,i20,i21,i22,i23,i24 project. pto @"%HUGIN%\cpfind.exe" --multirow --fullscale -o project2.pto project1.pto @"%HUGIN%\cpclean.exe" -o project3.pto project2.pto @"%HUGIN%\pto_var.exe" -o setoptim.pto --opt TrX,TrY project3.pto @"%HUGIN%\autooptimiser.exe" -n -o autoptim.pto setoptim.pto @"%HUGIN%\pano_modify.exe" --projection=0 --fov=AUTO --canvas=AUTO --crop=AUTO -o autoptim2.pto autoptim.pto @"%HUGIN%\hugin_executor.exe" --stitching --prefix=%Prefix% autoptim2.pto Then I have written a simple tool that makes test images: - generates a 4000x4000 image with random pixels - draw cross marker every 20 pixel - draw a one pixel wide frame - Save the resulting image - Cut 5x5 tiles, with 1000x1000 Pixel (250 pixel overlapped) and save this to image T00.tif..T24.tif. The random pixels cause that each pixel is a very good comparison candidate for finding Control Points. The marker and the frame facilitate the interpretation of the stitching result. I expected that panotools can stitch these tiles together only with errors in sub pixel dimension. But the error is significantly larger. After much trial and error I found a solution for this particular case. Based on the test images, I found out that pano_modify.exe caused the error. This program calculates the p line in autoptim2.pto: p f0 w6857 h6857 v129 E0 R0 S2928,6857,2928,6857 n"TIFF_m c:LZW r:CROP" I can correct this manually: - Open autoptim2.pto in hugin - On Sticher Tab, Change Field of View, Horizontal and Vertical from 129 to 130. - Press the “Calculate optimal size” Button. - Press the “Fit crop to images” Button The result is: p f0 w7014 h7014 v130 E0 R0 S3007,7007,3007,7007 n"TIFF_m c:LZW r:CROP" With these settings, hugin produces a sub pixel accurate image. Of course, that is not really a useful solution for me, because my batch file must provide a correct output image for any set of input images. Now my questions: 1. How can I automatically calculate the correct Field of View? Or even better: Is there a way, to bypass the unnecessary Field of View parameter, so that the intermediate images are not scaled.? 2. How can I avoid that w and h are unnecessarily large? Better as p f0 w7014 h7014 v130 E0 R0 S3007,7007,3007,7007 n"TIFF_m c:LZW r:CROP" would be p f0 w4000 h4000 v130 E0 R0 S0,0,3999,3999 n"TIFF_m c:LZW r:CROP" Expressed differently: How can I shift the projection to a minimum canvas? Or is the canvas size only a virtual size which is not physically created? 3. Why does the command line parameter " --dry-run "for hugin_executor not work? See *http://wiki.panotools.org/Hugin_executor* <http://wiki.panotools.org/Hugin_executor>. Are the individual commands documented somewhere else? If someone wants to try the test, here is my test image generator tool: *http://www.file-upload.net/download-11778244/I2T.zip.html* <http://www.file-upload.net/download-11778244/I2T.zip.html> Viruscheck: *https://www.virustotal.com/* <https://www.virustotal.com/> SHA256: ca729b9ba382d63a831a416fed2389647433476f1424b7616591a8abc2297e1d File name: I2T.exe To create the test images: Press „Random“ Button, Press „Draw Marker“ Button, Enter the target directory in the box to the left of the "Save" button. Press the „Save“ Button.
