Hi,
I have taken a Pc on server and want to process my data on it. I logged in via ssh.
But I cant seems to run agisoft itself. It is giving me this error

./photoscan: error while loading shared libraries: libQt5SerialPort.so.5: cannot open shared object file: No such file or directory

Can anyone tell me how to run it?

General / 2D image pixel to 3D world coordinate

« on: August 10, 2018, 04:24:10 PM »

I noticed that when images are calibrated, I can calculate 3D coordinate of any point in the image. So I was wondering how they do it? does anyone know how to convert 2D image pixel to 3D world coordinates?

General / 3D Geographic coordinate to 2D pixel coordinate

« on: June 26, 2018, 08:23:26 AM »

I want to transform a point given in geographic coordinate(Lat,Long,Ele) system to Pixel location(x,y) of image. I have processed images with agisoft and exported camera details like omega,phi,kappa, r11,r12,r13 etc. as text. Now I have a point which I want to convert to image pixel coordinate using python without using agisoft inbuilt function. Can you tell me how to do this?
For example I have attached, camera output file from agisoft. I have a coordinate Lat = 31.099338018;Long = 77.17603616;
Elevation = 2197.3547 and convert this into pixel coordinate.
Note - I have attached camera file with this post

Python and Java API / Python Scripting in buildddem. How to set resolution and resolution of dem?

« on: March 22, 2018, 06:44:12 PM »

I want to set resolution of DEM to be computed to 0.05 using python.
resolution_raster = 0.05;

I am using chunk.buildDem(source=PhotoScan.DenseCloudData,interpolation=PhotoScan.EnabledInterpolation,resolution = resolution_raster)

But I got error-- TypeError: 'resolution' is an invalid keyword argument for this function.

Can you tell us about how agisoft photoscan decides whether to reject a particular feature during matching or not? Does it follow the famous ratio test or you are using different algorithm?
