Hi people,

Someone knows what would be the value of the deviation standard from the laser in Player/Stage?

The standard deviation of laser range measurements is not defined.
There's no Gaussian error function on any range data by default in
Stage. There is aliasing error, but this is not unimodal so standard
deviation is not meaningful. You can impose one if you wish using the
provided plugin controller (examples/ctrl/lasernoise) with a variance
parameter.

Hi Vaughan,

thanks for the reply.

But I want know a value for standard deviation from the laser, to use in my algorithm of Markov Localization. I didn't understand what you mean about "provided plugin controller (examples/ctrl/lasernoise)". If that is a file, I didn't find it in my Player/Stage folders.

May you help me?

Regards,
Fernando - Brazil
