General / Alignment issue
« on: August 12, 2021, 10:19:49 PM »
Hello,
My data set consists of images of a straight lane of earth taken from a rover. The images are not geo-referenced. The alignment is all over the place and understandably so. In order to improve the alignment, I added 'fake' GPS data to the images. That is, starting with a gps coordinate, the successive frames were given GPS coordinates such that all the frames are in a single line. When I open the modified data set in Agisoft Metashape, the software recognizes this and shows that the images are perfectly in line (see attachment 1). But when I hit align cameras, the alignment is still very bad (see attachment 2).

Is there any way to tell agisoft software that the frames are roughly in a single lane, or is there any way to align properly based on the GPS data that I have given it?

Thanks,
Arjun

Python and Java API / Align recreated surface with horizontal plane
« on: July 14, 2021, 12:50:46 AM »
Hello everyone,

I want to align the recreated surface with the horizontal plane so that I can create a DEM with 'Current view' (being the TOP VIEW). I can do this manually in the UI by simply rotating it and approximately setting the top view and the create DEM with current view. The challenge I am facing is to do this with the Python code so that I can automate it. I am very new to this, can somebody please tell me how I can align the recreated surface to a TOP VIEW through Python? So that I can then do chunk.buildDem() over that next.
My picture data is not geo referenced FYI.
Any help will be greatly appreciated.

Thank you in advance!

Python and Java API / Rotation of recreated surface
« on: July 13, 2021, 01:39:49 AM »
Hello,

I am trying to produce an orthomosaic image from my data set using the Python API. But before that, I would first like to rotate the model so that it is aligned with the XY plane before I build the orthomosaic. Can someone please tell me how to do this with Python?

Thank you.

Python and Java API / Converting coordinates
« on: July 08, 2021, 06:18:55 PM »
Hello,

Given a 2D pixel coordinate on the orthomosaic, I want to do the following tasks:
- Convert it to world 2D coordinate
- project on DEM/model to gather Z coordinate
- reproject 3D point to source image
- get reprojection pixel coordinate on the source image (2D coordinates)

Could anyone please tell me how I can do these things with the Python API? My images are NOT geo referenced. I am doing this because I need a Python method to get the corresponding pixel coordinate on the source image given the coordinate on the ortho. I believe the above mentioned workflow is the way to do it.

Any help will be greatly appreciated.

Thank you.

Hello,
I have the final orthomosaic image. I want to do the following task:
- Given a pixel coordinate in the orthomosaic image, I want to find the corresponding pixel coordinate in the original raw image.
The images in my chunk are not georeferenced.

Any help will be greatly appreciated.

Thank you,
Arjun
