General / Orthofoto with roof overhang

« on: July 07, 2017, 03:19:24 PM »

I have to compute an orthofoto from a UAV image set. Since there is a big roof overhang ( and I need the ground to the walls of the building) I have to eliminate the roof.
Classifying my point cloud and only respecting the ground points gave me a very blurry wall-ground transition. A similar result gave me the elimination of the corresponding polygons of the mesh.
Good results I get with masking the roof. But that is very time consuming since I have 4 roos in about 150 images.
Is there another way to achieve a good orthofoto or is there a way to mask the roof only in some images and "translate" the mask into the other?
Many thanks,
Mathias

General / Importing shapes

« on: November 28, 2016, 11:16:08 PM »

Hello,
which conditions must a dxf or she file have that it can be imported as shapes.
I exported shapes into my CAD (works very well), edit the shapes and export them again as dxf or shape file.
But Photoscan does not read the dxf shapes at all and the shp-file shapes come in at 0,0.
Can someone help me here?
Thank you.

General / Clipping shapes

« on: November 28, 2016, 08:53:46 PM »

Hello,
is there a way to clip shapes?
Mean that I want to draw an adjacent shape to an existing one and I do not want to draw the adjacent border twice.
In GIS and CAD-Systems there is the possibility to clip these two shapes.
Can I do that in Photoscan?
Thank you

General / PhotoScan 1.2 computes wrong coordinate system orientation

« on: January 15, 2016, 01:25:23 AM »

Aligning a certain dataset in 1.2 does leads to a wrong coordinate system orientation. In 1.6 the orientation is correct.
Bug or mishandling?

General / Empty extent

« on: January 11, 2016, 09:14:31 PM »

If I try to generate an orthomosaic from the DEM of my project I get a "Empty extent" message after analyzing the DEM.
Generation from mesh works.
What is happening here?
