Detailed Description

Interface definition of the sensor_msgs/msg/MultiEchoLaserScan message.

# Single scan from a multi-echo planar laser range-finder
#
# If you have another ranging device with different behavior (e.g. a sonar
# array), please find or create a different message, since applications
# will make fairly laser-specific assumptions about this data
 
std_msgs/Header header # timestamp in the header is the acquisition time of
                             # the first ray in the scan.
                             #
                             # in frame frame_id, angles are measured around
                             # the positive Z axis (counterclockwise, if Z is up)
                             # with zero angle being forward along the x axis
 
float32 angle_min            # start angle of the scan [rad]
float32 angle_max            # end angle of the scan [rad]
float32 angle_increment      # angular distance between measurements [rad]
 
float32 time_increment       # time between measurements [seconds] - if your scanner
                             # is moving, this will be used in interpolating position
                             # of 3d points
float32 scan_time            # time between scans [seconds]
 
float32 range_min            # minimum range value [m]
float32 range_max            # maximum range value [m]
 
LaserEcho[] ranges           # range data [m]
                             # (Note: NaNs, values < range_min or > range_max should be discarded)
                             # +Inf measurements are out of range
                             # -Inf measurements are too close to determine exact distance.
LaserEcho[] intensities      # intensity data [device-specific units].  If your
                             # device does not provide intensities, please leave
                             # the array empty.
