As many of you may know, lidar sensors detecting range suffers under strong sunlight or/and reflective surfaces. It seems that some products handles strong sunlight better than others. I did a quick comparison between a TeraRanger Evo 60m and a Lightware LW20. The TeraRanger Evo 60m stop detecting objects over 18 meters, while the LW20 have no problem.
I find out, that 60m is only possible under very week sunlight and no reflections. I think that 99.9% of our flights does no match this scenario. TeraBee also provide data during test with strong sunlight. The detecting range drop significant.
My test, red=TeraRanger Evo60m, green=Lightware LW20:
I think the arducopter wiki should updated with a quick note, that the detecting range could be much lower than listed in the technical data. I bought the sensor due to the technical data who doesn’t mach to the reality…
What is your experience with rangefinders under strong sunlight?
