Does JMRI can deduce the precise location of a train from its speed,
it's size and a few object detectors ?
Yes. I have used the "LayoutEditor-Train Simulator Proof of Concept" to implement sound-follows-loco in VSD. See the attached screenshot. JMRI PanelPro and a LayoutEditor panel is needed.
Here is the location calculation:
With which precision ?
I think with a precision of 2-3 cm.
Does JMRI can use train precise location to automate the maneuvers,
including uncoupling and train formation ?
Partly. Not sure how "uncoupling" could be done. And I only used locomotive info, no train info.

Hello,
I have a few questions.

If yes:
* With which precision ?
* Does JMRI can use train precise location to automate the maneuvers, including uncoupling and train formation ?
Do you know of other software than JMRI who can do that ?
For my diploma work for engineering, I need to develop a system that can measure, or deduce, the precise location of a train, with a precision of 2-3 cm.
Then, using this location, the system need to automate the maneuvers, including uncoupling and train formation.
But before developing this system, I need to document what's already exist in the field of model making. And then found a new way of doing it.
I'm only allowed to develop something that nobody have already done.
For the detectors, it's seems that model makers have already done every possibilities.
Including using 2 objects detectors to measure speed (and JMRI already have a speedometer).
For positon deduced from other data, I have seen that JMRI already have a Train Tracker [1].
But, as I have only used the Decoder Pro until now, I don't know if the Train Tracker correspond to what I'm asked to develop or not.
Best regards.
PS: If my diploma work can be done, I plan to release the result software and hardware as free (as in freedom) software and hardware.
And all the documents in similar licence. And if it implies modifying JMRI, I would be very happy to send my modifications as contribution to JMRI.
