Measuring Vehicle Speeds
For approaching targets, aim the LIDAR’s reticle at the front grill or
front license plate of the vehicle. Good targets for receding vehicles
are the license plate or tail lights. Use the boundaries of the reticle
pattern to ensure only the intended vehicle is being targeted.
Squeeze and hold the laser fire trigger while maintaining your aim.
You may hear an intermittent audible tone as the LIDAR searches for
a valid target signal. You will also see “----“displayed in the HUD
indicating the laser is firing and a reading is being acquired. Once
target vehicle data is identified, the LIDAR will produce a continuous
lower frequency tone. When the data from the vehicle reaches an
acceptable accuracy level, audible tone will switch to a continuous,
higher frequency and the vehicle speed reading will be displayed in
the HUD and on the side panel.
Note: At typical distances the above acquisition sequence can
happen very quickly and you may simply hear the high frequency
tone and see the speed display immediately.
A positive speed reading will be shown for an approaching vehicle,
while receding vehicles are indicated with a negative reading. (Note:
Both the HUD and the side panel will show a “-“ sign for receding
vehicles.)
The DragonEye Compact Speed LIDAR
TM
will continuously update the
target’s speed reading at an approximate rate of 3 times per second
as long as the trigger is depressed and the data quality is acceptable.
While not required, it is recommended to track the vehicle for at
least 1 second to establish robust confidence in the speed reading.
