General / Exporting camera calibration parameters
« on: April 18, 2016, 04:20:23 PM »
I am trying to export camera calibration parameters as ini file but looks totally different values than other format.
Please look attached files.
How can I fix it.

General / Solving inverse camera, single image
« on: April 18, 2016, 10:28:03 AM »
I want to get exterior orientation of camera using single image:
Is it possible in PhotoScan and if yes how can I import my txt file.

I have the following inputs:
image coordinates: row, col
World coordinates: X, Y,Z

txt file format: // single image//

initial interior orientation of camera
id row col X Y Z

output:// I need//
 exterior orientation of camera
refined interior orientation


General / Orthophoto generation with only control points
« on: February 02, 2016, 03:31:02 PM »
I want to generate orthophoto by using the following steps:
1: Align all images by using control/ tie points
2: make surface by using these control points
3 Use this surface for orthophoto projection

These are typical steps in PhotoModeler. Is it possible to to  do it in Photoscan.  Is there any other solution. Task is to have orthoimage.

Attach please find images.

Is there any software for photo planning and GPs waypoints. I m looking for some free/ cheap solution.

General / Values of re-projection errors.....
« on: November 06, 2015, 02:18:35 PM »
I wanted to know what are the  default/acceptable/good values of :
                                                                                 1: re-projection errors
                                                                                 2: reconstruction errors
                                                                                 3: imaging count
                                                                                 4: Project accuracy

You can place some markers to  avoid such problem.

you can use Cloud Compare. It can handle level of details.

General / Camera calibration for UAV projects
« on: August 27, 2015, 10:17:52 AM »
I  want to know the proper calibration process for my camera especially for UAV projects.

The lens is:
Sigma 24mm F1.8

I used  Agisoft Lens for the calibration but  confused about the camera setting.

My questions are:
1: What should be my distance from the computer screen. Camera distance from the object can be 50-60 m from the object in real project.
2: What should be maximum angle.
3: Should it be auto-focus or manual.
4: Is there any thing which should I consider.
5: Should the calibration 2D (plane screen ) or 3D object (if so what and how can I use it Agisoft Lens)

Although I have searched on the forum for my question  but if it is already answered please share link with me.

Is there any stand of Agisoft in intergeo.

Is it possible to have auto fill function  for markers in orthophoto generation. At the moment I 'm typing markers ,require resolution etc. and if I forget some thing etc. I have to type all info again. If there will be last saved info, you can just change them.

If you want to you the same model,  use some projection pattern or spray it  etc. The disadvantage is that you have problem with texture.

@ Alexey Pasumansky

1: I made an  orthomosaic A (raw).
2: Now I edit it and made my final  orthomosaic A.
3: I can export it (my final  orthomosaic A) as jpg etc.
3:Now I made another raw orthomosaic B in the same project/chunk and similarly I  exported it too.
4: Now if I have to edit orthomosaic A, I have to produce it again in the project. which make no sense.
5: How can I save orthomosaic A (from step 2). so that I can import it any time in the project to edit it if required.

I can export all images in the format you mentioned. But how can I have use these images for the next time to make my orthophoto. Is there any option of importing orthophoto and editing it in Photoscan.
