inverted depth of reconstructed scene
« on: January 07, 2013, 03:37:43 AM »
Hello, I have just started PhotoScan since yesterday.

I've tried with my series of photos of a Japanese Garden.

Reconstructed result was fairly good, but the depth was totally inverted.
Close landcover bush in front of my feet was placed far,
and the trees behind them are placed closer.

I took photos with FujiFilm FinePix W3 Stereo vision camera.
Each pair of JPEGs are separated into 2 photos, with PC software.
Thus, I used photos of stereo pairs (more than 90% overlapped) and
each pairs overlapped 40 to 60 % each other.

Any suggestions?

P.S. I am very wondered that AGI crews magically integrated lots of
different multi-view reconstruction techniques and many I/O utilities and GUI
into this single package. Wonderful.

Hello can you share your dataset ? - confidentiality is guaranteed

Best over DROPBOX or some sharing site.

The camera has litle distance between lenses, it can cause problems on objects that are far away - im guessing more than 5 meters - the stereoscopy dispaear and it cause problem for pscan to align it as it should. But need to test it...... contact me on muzeumhb@gmail.com

hey...

occasionally I got inverted reconstruction.. but it gets inverted at alignment stage in my case, so off course reconstruction is inverted, and mesh normals are pointing the wrong way..

after small investigation, it appears that PScan does not like lens corrected images (lightroom4) and a combo of 100 mm lens...

... and leaving the non corrected images works normally, no inversion..

@Alexey, I have saved both PSZ files, let me know if you need them..
