HAP (TX) cannot precisely detect objects which are less than 0.5 m away. In this
situation, the HAP (TX) will output warning message for blocking, and the serial number
of the HAP (TX) displayed on Livox Viewer 2 will change color to warn users. If used at
the time, check the SDK for more information about the warning. The point cloud may
distort to a varying extent when the target object is within the range of 0.5 to 2 m.
The HAP (TX) has a detection accuracy of 2 cm when tested at a temperature of 25° C
(77° F) with a target object that is 20 m away and has a reectivity of 80%. The actual
environment may dier from the testing environment. The gure listed is for reference
only.
The performance of the HAP (TX) may decrease in extreme environments, such as those
where the temperature is -40° C (-40° F) or 85° C (185° F) or those that cause high
vibration.
The performance of the scanning method is defined by the FOV coverage, which is
calculated as the fraction of FOV illuminated by laser beams. The FOV coverage (C) can
be calculated with the following formula:
Refer to the ocial Livox website for more information about how the FOV coverage is
calculated.
