[Robotics] Camera calibration parameters

[Gilberto Echeverria]

Hello everyone,

As part of the Open Robots Simulator (now called MORSE), we are now 
connecting Blender with other robotics software modules that do the 
processing of the data sent by the simulation. In the case of image data 
from a camera, these modules expect the image to have an associated 
calibration matrix.

The calibration matrix is composed with the focal point, the focal 
length and the dimensions of the acquired image as a number of pixels 
per unit of distance. For the simulated camera in Blender, we can 
consider the focal point to be (0,0). For the other two parameters we 
have been unable to find the data in Blender. We are using the Blender 
camera object and the VideoTexture module to generate captured images. 
Does anyone know where this information could be found in Blender?

Best regards

Gilberto
