4.3.Reflectivity
RS-Bpearl measures the reflectivity of objects. The reflectivity is an index that measures the
ability of an object to reflect light and is greatly related to the material of the object itself.
RS-Bpearl reports calibrated reflectivity values from 0 to 255, among which diffuse reflectors
report values from 0 to 100, and retroreflectors report values from 101 to 255. Black objects are
with low reflectivity values, white objects are with high reflectivity values, the most ideal
reflection reports the reflectivity value of 255.
