That is a better explanation of what I have been saying.......that IF the pictures were to scale (ie vehicles should be 2.6m wide) then there might be less chance a lidar could get #2.
Veh 1 width of 2.6m, 500m the beam is 1.5m wide...therefore the whole beam can be placed on the car...
Veh 2 width is 2.6m, 570m the beam width is 1.71m wide...therfore the whole beam can be placed on the car.
Now what we have is the angle from the lidar to the vehicles, on a angle, can it target the 2nd vehicle? There is also sideways movement within the lane (as it is 3.75m wide) that also is not taken into account. Which each vehicle could move 1.15m left or right. This could add up to another 2.30m of lateral difference.
