Signifcant error in total error to do with cameras
« on: November 12, 2015, 01:36:40 PM »
Hi there,


I am reading the report for the DEM that I am generating - I have 2 problems, the total error for the camera position is rather large, is there anyway I have done anything wrong within this project to cause this or is this correct? Also my projected DEM seems to suggest that elevation is continuous and doesn't seem to make much sense,, is there anything I can do about this also?

Thanks
Lou

May be a screenshot or the discription of your workflow would help...

Hello LouFlat12,

Is it possible that incorrect coordinate system is set in the Reference pane settings dialog?

Hi,

I've been using WGS 84 (EPSG::4326), my study site is in Northumberland, UK, I thought this was correct?

Looking at my camera information the lontitude seems very off, this could possibly be why the error is so large, is there anyway to solve this?

Hello LouFlat12,

Can you send the project file to support@agisoft.com? (please remove depth maps, dense point cloud and mesh from the project to reduce the file size).
