Map with Car Observations and Particle

Map with Car Observations and Particle

Associations

Now that observations have been transformed into the map's coordinate space, the next step is to associate each transformed observation with a land mark identifier. In the map exercise above we have 5 total landmarks each identified as L1, L2, L3, L4, L5, and each with a known map location. We need to associate each transformed observation TOBS1, TOBS2, TOBS3 with one of these 5 identifiers. To do this we must associate the closest landmark to each transformed observation.

As a reminder:

TOBS1 = (6,3), TOBS2 = (2,2) and TOBS3 = (0,5).

TOBS1 Association

QUESTION:

Which landmark identifier is transformed OBS1 associated with? Answer either L1, L2, L3, L4, or L5.
