Check pre-Release 1.2.0...

There you can build an Orthomosaic and preview it in the Workspace

Hallo

I Try to upload some data to mapbox.
Now every time apears the error attached.

I think its cose of the API token. Can anyone tell me which API is required?
I tried both (privat and public)  and it don't work.

Thanks in advance

which is your resolution in the pictures? can you upload some originals on dropbox?

You have to convert the UAV-Coordinates into UTM befor importing the GCP.
otherwise both coordinates will be transformed, not only the UAV-Coo.

hope that helps.

there is nothing more to say, james already eplained the problem verry well! -thx!

As you can see in your case, in some aerea the overlap is good enough...
Hope you can finde a solution...

Or just take this python-script to rotate the Boundingbox to coo-sys.

Hi

how big is the aerea you surveyed?
it would be great to see the mosaic.
and also can you upload the report, generatet from agisoft photoscan?

hope i can help...

hi!

normaly, roads are no problem. they actualy have a verry good texture for photogrammetry.
tho only thing you have to look for is, that you have enough overlap in each image.

you can put your sampledata online? so I can have a try.

Hi

in the Orthophoto output-menu, check "Split in blocks"
There you can also fix, how big the block should be.

hope that helps?

check www.wetransfer.com
there you can send up to 2 GB free, the client will recive a link to download the dataset.

Do you have a printscreen of the GCP in PS?
You chose the right Koo-System?

and you've done the cameracalibration after the GCP-mesurement?

Python and Java API / toolbox dos not work since Update
« on: April 08, 2015, 09:00:32 AM »
Hello

I have a personal toolbox (code see bolow)
scince update to 1.1, the toolbox does not work. that means the comands from  the toolbox (Smooth & boundingbox...)

does anyone have the same problem or know what I should do?

****************************************************************************************************************************

import PhotoScan, math

def main():

   doc = PhotoScan.app.document
   chunk = doc.activeChunk
   
   if chunk.model:
      x = PhotoScan.app.getInt("Input number of smoothing steps:", 3)
      chunk.smoothModel(x)
      print("Smoothing by script finished.")
      return 1
   else:
      print("No model. Script aborted.")
      return 0

PhotoScan.app.addMenuItem("ristag/Smooth model", main)   

thanks!


def rotateBb():

   doc = PhotoScan.app.document
   chunk = doc.activeChunk
   
   T = chunk.transform
   v = PhotoScan.Vector( [0,0,0,1] )
   v_t = T * v
   v_t.size = 3

   m = chunk.crs.localframe(v_t)
   m = m * T
   s = math.sqrt(m[0,0]**2 + m[0,1]**2 + m[0,2]**2) #scale factor
   R = PhotoScan.Matrix( [[m[0,0],m[0,1],m[0,2]], [m[1,0],m[1,1],m[1,2]], [m[2,0],m[2,1],m[2,2]]])

   R = R * (1. / s)
   reg = chunk.region
   reg.rot = R.t()
   chunk.region = reg

PhotoScan.app.addMenuItem("ristag/Bounding box to coordinate system", rotateBb)

General / Areal Photogrammetry with Sony Nex7
« on: July 14, 2014, 09:19:33 AM »
Heey

Has anyone tested the Sony Nex7 with Sigma 19mm f2.8 dn for aereal photogrammetry?

I will use it to create DEM and Orthophoto

Thanks
