In the 3D camera simulation (https://www.mathworks.com/help/driving/ref/simulation3dcamera.html) - there is no specific focal length (mm) for the camera intrinsics. I'm working on feature tracking using the camera feed and I cannot estimate the 3D location of a point without knowing the focal length or the scaling factor (w) in (https://www.mathworks.com/help/vision/ug/camera-calibration.html).
It would also be great if MATLAB provides a DEM of the UAV scenarios - ground truth for many applications.

Please take a look at this page:
If you know the size of the pixel in world units, you can convert focal length in world units (usually mm) to focal length in pixels.
