Python and Java API / Multi GPU enable using python API.
« on: October 21, 2018, 01:48:48 PM »
I have 2 GTX 1080. I want to enable both GPUs for processing using only python API. Can anyone tell me how to do it?

General / Agisoft on ubuntu server via ssh
« on: October 20, 2018, 12:42:21 PM »
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 -r Photoscan_server.py -platform offscreen"

./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?

This because matches are also filtered based of spatial location and orientation (Look for fundamental matrix outlier detection). This will calculate relative location and orientation of multiple images  and if certain match pair don't satisfy this constraint then it will be rejected, hence they depend on surrounding images,

Given you have a very high budget, It wouldn't be a problem for you to explore server cpu series  since they can scale to multiple cpus. Looks for AMD Epyc series. It would be a good start for making scalable hardware instead of buying just individual cpus like threadripper or i9

Go for
1. Ryzen 2700X CPU
2. GTX 1060, 6GB GPU
3. 32 GB Ram

General / [Help] Large error in GCPs
« on: August 03, 2018, 09:37:04 AM »
I have a small project of  <2Km. I have 220 images and 5 GCP points. I have marked 3 as GCP and 2 as check points. However I am getting large error >5m in checkpoints where as <5cm in GCPs. How to process it correctly can anyone tell?

General / Re: Dense cloud below the ground surface
« on: June 27, 2018, 12:12:57 PM »
This is due to texture less surface of Snow. Because of that a lot of points which  are matched are incorrect hence you are getting points below ground.
Try running denseCloud with aggressive filtering. This might remove outlier a lot

General / Re: Geographic coordinate to pixel coordinate
« on: June 26, 2018, 08:45:55 AM »
I have tried following method
1. Point P, Lat, Long to ECEF coordinate system
2. Pw in world coordinate to P in camera coordinate using Pc = inv(R)*P. Where R is rotational matrix and P is point in ECEF
3. Then Camera coordinate to pixel coordinate using K*Pc. Where K is [f,0,cx;0,f,cy;0,0,1]

I searched web also and found above pipeline. But It is not working correctly.
Coordinate which I got using agisoft internal functions are 2393.17, 3641.62 at image DSC04045_geotag.JPG but using my method I am not getting similar results

General / Re: Problem with align of forested images
« on: June 26, 2018, 08:25:51 AM »
Yes, In case like these it is very difficult to extract feature and match them.
Although try aligning photos with lowest accuracy. This will increase some of the matches and you might get correct photo alignment

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

Hey TXPE,
That looks really great. Its very huge project. Must have experience difficulty while processing. Can you share your processing experience here? How you managed to pull off such a huge project?
