Projective matrix, intrinsic and extrinsic parameters

, someone else use

P: 3×4 matrix

Decomose K,R,C from P:

K: 3×3 — intrinsic parameters

R: 3×3 — extrinsic

C: 3×1

Try:

• from p,p’ to F and do reconstruction (works, similar result with my axial method, maybe the math inside are the same)
• ma3d reconstruction
• rectify two close frames (doesnot work, need to check the process of rectification)
