Re: [simspark-devel] About Noise and Restricted Vision

[Sander v. D. <sgv...@gm...>]

Perhaps we can just use the model of the old spheres simulation? Quoting
from TEXT_INSTEAD_OF_MANUAL:

  371 The noise parameters of the vision system are as follows:
  372
  373 - A small calibration error is added to the camera position. For each
  374 axis, the error is uniformly distributed between -0.005m and
  375 0.005m. The error is calculated once and remains constant during the
  376 complete match.
  377
  378 - Dynamic noise normally distributed around 0.0
  379   + distance error:  sigma = 0.0965
  380   + angle error (x-y plane): sigma = 0.1225
  381   + angle error (latitudal): sigma = 0.1480
