Effective Distance
The effective distance of the laser is 0.1m-30m during normal running, so when the laser is
very close to the object, the laser data may be inaccurate. Therefore, the laser shall not be
particularly close to the wall or other objects when using it (at least 10cm space should be
reserved).
Reflectivity
The reflectivity of the laser is usually related to the intensity of the energy returned by the
laser, so objects with high reflectivity (reflectors) will have a higher reflectivity, and ordinary
objects will have a lower reflectivity. Usually, we normalize the reflectivity to 0-255, where 0
is the lowest reflectivity, and 255 is the highest reflectivity. The reflectivity of general objects
is less than 150, and the reflectivity of special diamond reflectors is more than 200. You can
know the reflectivity of a laser point through the laser point color on Roboshop, as shown in
the figure below:
