About Camera projection center in Metashape
« on: November 07, 2022, 06:09:12 AM »
I have a question about camera projection center described in
Appendix D. Camera models section of
https://www.agisoft.com/pdf/metashape-pro_1_8_en.pdf .

Is camera projection center "optical center of lens" or "center of CMOS image sensor"?


My understanding is "optical center of lens" in attached image.

Is it right?

Yes the camera projection center O is the "pinhole" in the camera pinhole model, where the principal point H' is the base point of O in the sensor area (with it's offfets Cx and Cy to the sensor center).
