Profile Output in Profile and Raw Mode
Profile data produced by Profile Mode and Raw Mode follows different formats. In Profile Mode, the data is re-
sampled to an even interval along the laser line (X). The re-sampling divides the X-axis into fixed size "bins" at even
intervals. Profile points that fall into the same X-resolution bin will be combined into a single range value (Z).
In the Ethernet data channel, only the range values (Z) are reported and the X values can be reconstructed through
the array index at the receiving end (the client).
Re-sampling reduces the complexity for downstream algorithms to process the profile data from the Gocator, but at
the cost of higher processing load on the sensor’s CPU. Re-sampling also reduces the bandwidth requirement by a
factor of 2 compared to Raw Mode.
In contrast, in Raw Mode, the profile data is not processed in any way. The data is reported in (X,Z) co-ordinate
pairs, freeing up processing resources in the Gocator, but typically requiring more complicated processing on the
client side.
All built-in measurement tools in the Gocator operate on re-sampled data in Profile Mode.
