Starting up
« on: October 29, 2015, 10:32:36 PM »
Hello to everyone,

I am completely new to photogrammetry and testing now agisoft for the first times.
I am trying something easy to see how far i can go, but i am sure i am missing something.

here is an example of the photos i have taken (61) in tif format and around 5k in size with one canon mk3 with a 50 mm lens inside a small lighting studio setup.

I am simply rotate the head and take the photos at different heights, but once i align the photos i get this

i have tried to build the point cloud to see the results, but its even worst, what can couse this result?

thank you for the help

If that 1st image is an example of your input images, you should bring the camera closer to fill the frame with the subject. That will help. If you still have trouble you will need to mask out the background. You can do that automatically by taking a photo of the background without the head in it, but the moving shadows might not get masked properly
