18. Quiz: Association
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).
