Setting vertical field of view VZ-400

[HELIOSHD]

Hello and thanks for the great work!

I was wondering how I can define the vertical field of view for the Riegl VZ-400 in HELIOS using a levelled scanner. For the horizontal field of view this is possible with "headRotateStart_deg" and "headRotateStop_deg". If doing the same for the vertical field of view the I only get a narrow strip which does not correspond to the desired absolute vertical field of view (e.g. absolute FOV = 30°, starting at -5° and ending at +25°).

Best regards

Now is possible to set the vertical field of view of the scanning. For this, go to the survey XML and add on each <scannerSettings> the desired min and max values with verticalAngleMin_deg="angle" verticalAngleMax_deg="angle". The scan angle range is set automatically by reading those min and max.

This example shows how to set the vertical FOV to (-5º, 25º):

  <platformSettings x="0.85" y="25.58" z="0" onGround="true" />
  <scannerSettings active="true" pulseFreq_hz="100000" scanAngle_deg="50.0" scanFreq_hz="120" headRotatePerSec_deg="10.0" headRotateStart_deg="128.91" headRotateStop_deg="223.45" verticalAngleMin_deg="-5.0" verticalAngleMax_deg="25.0" />
