This PR introduces point filters designed with a novel method:
a. the effective angular resolution
b. the number of overlapping LiDARs in every region
The first results can be seen here:
point_filters_fullpoint_filters_one_thirdThese filters are not yet final and are more of a proof of concept.
With the same methodology and proper testing for low obstacles and far-away cars, production-ready filters can be designed with relative ease.
See TIER IV INTERNAL for details on the design process.
