General / Distance from Scalebar
« on: March 11, 2018, 02:07:42 PM »
Hi

My goal is to monitor a distance between two targets:

I would like to set a image scale with two targets groups (Targets A,B,C & X,Y,Z), give them a scale with some specific scalebar distances (A-B, A-C, B-C and X-Y,X-Z,Y-Z).
then need to estimate the distance between target A-X.

Is there a possibility to do that in PhotoScan with only one Image?
See following sketch

General / Black marks in an orthophoto
« on: January 07, 2016, 12:50:20 PM »
I got some problems in Orthomosaic:
specialy in forest area I got holes in Orthophoto - see image.
is there any workaround to fill / blend these holes.
I know it is cause the area isn't on any image. bit may be I can do something expect of a new flight...

hi everybody

I try to setup a network cluster. now i can not connect the clients.

Thanks

General / Crash while building Orthomosaic
« on: October 26, 2015, 07:04:22 PM »
Dear alexey

I have a big probleme while building an orthmosaic of a street-scan:
My workfow is:
1. align Photos (medium / Generic (I don't have coordinates of the Photos))
2. mesure control-points (4 in total)
3. split in Blocks/Chuncks
4. build densecloud (High / agressiv)
5. build DEM (from dense cloud)

So far every thing works well.
then i try to build Orthomosaic with surface DEM with a resolution of ~3mm (lower than original resolution).
After may be 40% photoscan crash and following problem apears:

What can be the problem? I tryed with smaler chuncks and so on but nothing helps.
When I try to export an orthomosaic with a resolution of 1m it works, but i dont think it is a ram problem (I got 64GB...)

General / offline Google map
« on: October 14, 2015, 09:35:49 AM »
Hi

I would like to export an Orthophoto by exporting "Google Map Tiles" and open the map in Firefox.
Works all very well and fast... perfect!
BUT:
My map is up to 0.5 cm GSD. it looks that in firefox i can only zoom up to zoomlevel 22  although the tiles are exportet with Zoom level up to 24.

in the file "index.html" (generated by export), i set the zoo,level already to 24, but nothing happens.
can anyone help me please? that would be very great!

as an attachment you can see the index-file.

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 / Pointcloud to Mesh in v1.0.2
« on: February 21, 2014, 01:18:24 PM »
hello everyone!

I have a problem when i go from Pointcloud to Mesh:

Pointcloud looks good, but when i generate the Mesh (Highfield, High, from Dense Pointcloud) one building-wall is very bad...

As an attachment i have a picture, left the Mesh in Top view and Orthografic, right the same sector with the same view from the Pointcloud...

And a view from the side. (red line is plumb line)

Any idea whats wrong? never had this problem bevore v 1.0.2
