Determine the dead angle
The dead angle of a panorama head depends on construction of the panorama head.
To determine the dead angle of a specific panorama head is quite easy.
Procedure:
- Establish the tripod, camera with lens and Pivot Point adjusted
- Swing the elevator upward to bring the camera view to Nadir -90°
- The camera viewing centre should be adjusted to look exactly to the horizontal
rotating point of the PanoMachine.
- While rotating the panorama head 360° around the horizontal axis, check which
parts of the panorama head are permanently covers the view to Nadir.
- Now rotate the elevator downward till the panorama head isn’t visible in the
cameras angle of view.
- On the PanoMachine read on the elevator scale the difference angle to Nadir -
90°.
- Multiply this angle by two an insert this value and insert it in the database to
row in the very right field “Dead Angle [°].
When measuring a difference angle of 10°, the value to insert into the database is 20°.
