Fx Fy Cx Cy  K1 K2   P1 P2  K3   This one Consistent with Pix4D camera model,so in PhotoScan:

pix size = 0.0024

f=(fx+fy)/2 // or  f = fy   and  b1 = fx-fy
cx = cx
cy = cy
K1 = K1
K2 = K2
K3 = K3
P1 = P2
P2 = P1

My opinion can be verified:

Bentley CC is compatible with the PhotoScan camera model, and only self-calibration is used to observe the self-checking results of CC P1 P2.

rather  f = fy   and  b1 = fx-fy, I think
