Title: Can't align photos
Post by: zielony on September 08, 2013, 03:09:30 PM

I was trying to create a model of my training bag,
i took 20 pictures and those pictures cant alignt correctly, i tried to do this several time with no luck.
I took all the tips in mind, my pictures were overlaping, the bag isn't shiny ect

is it possible to take pictures in normal living room to use in agisoft ?
after this i'm taking ma camera and will try to shoot some statue out in the city and see if it helps

Hello zielony,

If possible please provide at least several original images to support@agisoft.ru, so we could check the image quality and etc.

Hello zielony,

Thanks for providing sample images.

The main problem is in lack of EXIF data for the images - there's no information about sensor pixel size, so PhotoScan initial calibration data may be incorrect. For the small sub-set PhotoScan was able to estimate the focal length. So I can recommend either to input pixel size in mm values in Tools Menu -> Camera Calibration dialog (if you can find this data in the camera/device specification sheet) or try to use values for Fx and Fy in pixels that we've got for the sample images - 2600 pix. Do not forget to click OK button.

Let me know if this advice helps.

Also don't forget to resize the bounding box before geometry reconstruction to the object of interest.

Ok using 2600 didn't help much, but i've found the sensor size, but i don't know where to put it in mm

fx, fy, cx, cy, skew, k1, k2, k3, p1, p2  - these are the boxes i have

before, those values (2600) i did put in fx and fy

Hello zielony,

Starting from the version 0.9.1 there are fields for sensor pixel size and focal length, we recommend to use the latest release.

oh i didn't know i have old trial version, downloading the standart version 0.9.1 trial, hope i will make it this time ;)

If there are still problems please provide the whole dataset.

Yes i still have that problem, i will try to redo a dataset tomorrow, and if i still have that problem i will send it to you

and my friend did send me his data set (without sensor size in EXIF) and his photos align great,
i will post tomorrow my progress

Ok guys, i've send you full dataset

this one aligns much better but still i can't generate any decent model, please help, i must be doing something wrong
