it's a very normal camera projection method from after effects

i have an original footage with a person standing slightly left of the white board.

i 3d camera tracked and place three solid plate on font wall, left wall, and floor.

then i duplicate the original footage and mask out the person, and place it on front of camera and light

then i project it to the solid plates, to do the camera projection.

but since the footage is a a nodal pan, the changes of perspective is more than slight

so i gonna do 3 camera projection, but when i place three all together, i can't see anything other than the first layer(means other two camera projection precom underneath cant be seen), then i decided to use play with luma matte and levels to create the alpha channel, so three layers can be seen,

but the problem is when i reveal all three camera projection together, i saw the white edges, it's weird...

I would do this as three images on three planes: Straighten the two walls and the floor into rectangular images in Photoshop, bring them into AE and turn the layers into 3D, align walls to floor.

Or is there a reason to do this as camera projection?

In terms of your original white edges problem, you could expand the matte edges. Or draw masks instead of using a key.
