Cannot be adjusted to POS
« on: July 23, 2021, 09:33:15 PM »
Usually when optimizing the camera, parameters such as f cx cy will be checked.

If the control point and the Z of POS are not in the same coordinate system, it will cause a lot of trouble. You will find that f is optimized very small.

If you uncheck f, you will find that there is no optimization at all.

This reminds me of inpho, which spreads the residual of the adjustment into the x y z of POS, which effectively avoids the problem of control points and POS elevation z, which are not in the same coordinate system.
