How to model a depth sensor using OGRE camera class

[shome]

I need to represent a depth sensor using OGRE camera class:

the sensor focal length is 574 pixels, the FOVy and FOVx are 57 degree and 45 degree respectively

the sensor params are as below:

depth image height: 480
depth image width: 640
distortion_model: plumb_bob
D: [0.0, 0.0, 0.0, 0.0, 0.0]
K: [574.0527954101562, 0.0, 319.5, 0.0, 574.0527954101562, 239.5, 0.0, 0.0, 1.0]
R: [1.0, 0.0, 0.0, 0.0, 1.0, 0.0, 0.0, 0.0, 1.0]
P: [574.0527954101562, 0.0, 319.5, 0.0, 0.0, 574.0527954101562, 239.5, 0.0, 0.0, 0.0, 1.0, 0.0]
