General / Re: Orientation in model with arbitrary coordinate system

Thank you for the help, I just send an email with the relevant information!
I tried different settings you proposed, so some of the images are from a different working file, all with the same problem though.

My project is not aerial but I have taken the pictures with a hand held camera aimed towards the ground, so they are kind of taken from above. So now my Z-axis is not pointing in the direction i'm expecting, do you have any suggestions where the problem could be?

Thank you so much for your help!

Hello Alexey,

Thanks for your quick repsonse.

It doesn't look like it is just upside down, it looks like the whole model is mirrored after I try to build texture and a DEM.
I could retry alligning the photo's with X and Y swapped but since it is an arbitrary system this shouldn't change the relative distances and altitude difference between the markers right?

General / Orientation in model with arbitrary coordinate system

« on: January 09, 2017, 12:49:21 PM »

Hi all,

Somewhere in my workflow i'm causing my 3D model to be inverted. I have a model with 400 photo's and 7 groundcontrol points measured in a arbitrary coordinate system with a Total Station (need high accuracy(<5mm) points!). I worked with Agisoft before, but this is the first time I work in an arbitrary coordinate system instead of world coordinate system
X range: 29.7664 - 70.0173 meter
Y range: 15.7528 - 47.3623 meter
Z range: 18.912 - 64.4892 meter

I need a DEM and orthophoto that are overlying each other to calculate volume of a part of the model (in ArcGIS for example). After alligning the photo's I placed the markers in the photo's and model and calculated the dense cloud and mesh/texture. I think the problem is related to the moment in my workflow where I calculate camera locations based on the coordinates? My cameras are unchecked and my markers are checked when I calculate the dense cloud, i'm not sure if this is correct.

Hopefully somebody is able to shed some light on my workflow or has some examples that also work with arbitrary coordinate systems.
