Rangefinders (landing page)¶
Copter/Plane/Rover support a number of different rangefinders including Lidars (which use lasers or infra-red beams for distance measurements), 360 degree Lidars (which can detect obstacles in multiple directions) and Sonars (which use ultrasonic sound). This category also includes Maxbotix Sonar and Pulsed Light LED range finders. These devices can be used for measuring distance near to the ground for precision landings and altitude control, water depth, or object distance as proximity sensors for Object Avoidance. Vision systems (see Intel RealSense Depth Camera) can also be used for Object Avoidance.
A forward facing rangefinders can also be used for Obstacle Avoidance. See Rangefinder Setup Overview to know more.
If you get a “Bad LiDAR Health” message in Mission Planner this
is caused because the rangefinder isn’t enabled for landing. This is
done through the
RNGFND_LANDING parameter and if set you should see
the message disappear.
RNGFNDx_MAX_CM must be set to a tested, appropriate value. If
RNGFNDx_MAX_CM is set to a value
greater than the range of the sensor, the autopilot will not respond correctly to the
