I have been trying to get camera(perspective) projection matrix from camera 
parameters..

that is

{
    perspective
   //location  <0, 0, -8>
   location  <15, 5, -15>
   direction <0, 0, 1.0>
   up <0,1,0>
   right <1, 0, 0>
   look_at   <0, 0, 0>
}


Is there any way to get camara projection matrix?

Please help me.

thanks

perhaps I'm misunderstanding, but if that is literally the syntax you are 
using you are missing the camera keyword .....

ie:

camera {
  yourstuff
  }

You can't get the projection matrix for a camera already defined, but you 
can construct a projection matrix yourself and create your camera from that. 
It can be rather easy using the right macros. I suggest you have a look at 
the screen.inc file that comes with POV-Ray.
