Detailed Description

sick_scan_api: struct SickScanPointFieldMsg, equivalent to ros::sensor_msgs::PointField
SickScanPointFieldArray is an array of SickScanPointFieldMsg, which defines the structure of the binary data of a SickScanPointCloudMsg.
SickScanPointFieldMsg for pointclouds in cartesian coordinates with fields (x, y, z, intensity):
    [ SickScanPointFieldMsg(name="x", offset=0, datatype=FLOAT32, count=1), 
      SickScanPointFieldMsg(name="y", offset=4, datatype=FLOAT32, count=1),
      SickScanPointFieldMsg(name="z", offset=8, datatype=FLOAT32, count=1),
      SickScanPointFieldMsg(name="intensity", offset=12, datatype=FLOAT32, count=1) ]
SickScanPointFieldMsg for pointclouds in polar coordinates with fields (range, azimuth, elevation, intensity):
    [ SickScanPointFieldMsg(name="range", offset=0, datatype=FLOAT32, count=1), 
      SickScanPointFieldMsg(name="azimuth", offset=4, datatype=FLOAT32, count=1),
      SickScanPointFieldMsg(name="elevation", offset=8, datatype=FLOAT32, count=1),
      SickScanPointFieldMsg(name="intensity", offset=12, datatype=FLOAT32, count=1) ]
