Camera Calibration / Camera Orientation - Camera calibration Lens
« on: December 16, 2021, 11:41:43 PM »
Hi Everyone.

I have a doubt about what is coordinate system that cameras 's Rotation and position (x,y,z) referenced?

I did a calibration using a printed checkerboard pattern on metashape and I input the focal length and pixel size manually, because images doesn't have EXIF data.

I export Cameras in omega phi kappa format, but i don't understand what coordinate system it's referenced.

Images the camera calibration lens:

Hi, everyone

I've read this post https://www.agisoft.com/forum/index.php?topic=10730.0 to extract tie points projection using Python.

I calibrated my stereo camera system using multicameras system getting the slave offset and orientation omega phi kappa. See this link with stereo calibration result:

I'm using the code in the first link to extract the matches points, I would like to save this coordinates in [u1,v1 u2,v2] format in txt file. How can i do that using Py?

u1,v1 are coordinates in the left image and u2,v2 are coordinates in the right image for each stereo frame.

I want to open this file in Matlab to calculate the fundamental matrix using an eight-point algorithm.
