known conditions:
- Camera 1 internal parameter matrix K1 external parameter matrix [R1 | T1]
- Camera 2 internal parameter matrix K2 external parameter matrix [R2 | T2]
Question: Reproject the image from camera 1 to the perspective of camera 2.
Formula derivation :
The coordinates P (X, Y, Z) of any point in space, the imaging process of this point in the two cameras is as follows:
This method can approximately reproject the image of camera 1 to the perspective of camera 2:
Original camera:
Reprojection:
