Did you work with ground points(with coordinates)? Is it necessary to have 3 points with absolute coord. or I can use some details on terrain?

You say 8 pairs?? I don't understand??

[Fotostacja]

I work with ground points. In this project I had 3 or more ground points for every stereopair. If you know the distance between two point on photos you can use it for creating model but accuracy is not so good (especially height). I wrote 8 pairs because when you upload more photos to the project it sometimes hangs, loosing information or working very slow. The best way is to create small areas and next combine them.

@slaven63

For you 1 pair - area more or less 52x80m

Between left and right image in pair overlapping is abut 80%.

WHAT???

omg!

I'm planing to put the area of 160 000m2 to render. Is it possible?? Should I divide it in parts?

How much overlapping you've done?

[Fotostacja]

This project is created from 16 stereopairs (13mln pixels photos). Overlap of diferent stereopairs is usually 20-30 %. Comfortable You can work with 8 pairs. How big are your photos ?
