hey try with accelerometers.... search about it... the iphone from apple has one of them... they use it to control the screen display with it... u can use it to tilt the cameras with respect to the inclined surface....

  Have a look at MEMS accelerometers. I'm using the Freescale 3-axis chip, 
  they are quite cheap.
