I'm looking for a definition of the coordinatesystems of the 3D object and the camera taking a picture of it.

i think the camera coordinate system is:

(Z is pointing into your screen)

^y ^z

| /

| /

|--->x

while the cam is facing in z-direction, but i just can't figure out the coordinate system of the 3D object.

i really hope someone has used this algorithm before and can help me out here.

What algorithm are you talking about ?

What do you want to do ? Project the position of the object on the camera ?

i'm talking about the posit algoritm of the opencv library.

i have problems with the coordinate systems. for example, if i get a 90 degree rotation around the z axis. in which direction is the z axis pointing and is the camera rotating 90 degrees or the object
