As you may know, the lidar works by measuring the number of photons as a function of time (at the scale of nanoseconds). Once you have such a time series, the ambient, intensity, and range are related as shown in this diagram.
Currently, the reflectivity is calculated assuming it is proportional to intensity * range^2, which is an approximation according to the inverse square law for Lambertian objects in the far field.
@dllu Thank you so much for your quick response. Understood the concept.
Hello all, I recently started to work with OS 2 128 channel lidar, and better choice for LiDAR-based object perception. But I have a few questions related to ambient and reflectivity data from the sensor.
How the ambient and reflectivity calculated ? is there any research publication that describes the method.
Thanks in advance,
Regards, Ajay
