Calibrating Pitch, Roll and Heading
The Dynascan comes ready calibrated for Roll and Pitch and these two values
do not need
changing
. The heading will vary between installations and should be calibrated for each
different vehicle or vessel used (heading starts at step 22 below).
I.
You need to find a flat area, such as a car park, with a tall lamppost or vertical pole in a
clear area with good GPS coverage. The flat surface will be used to calibrate roll and
the vertical pole for pitch and heading.
2.
Record four separate QINSy files by driving
slowly
(2-3 KPH) past the pole in each
direction (approx 10-20 metres away) and on opposite sides of the pole, as shown in the
plan view diagram below.
3.
Ideally you should drive in a straight line and when travelling
in the opposite direction come back along the same line.
Give logical file names to the 4 files (e.g. south of pole going
West).
4.
When you have recorded the four files go to the QINSy
console, open the processing icon and import the four files.
5.
Start by calibrating the Roll and select two files from two different directions and then
clicking on the validator icon.
6.
Select View, Plan View and tick the ‘Show Transducer Data’ box (this will show a fine line
on the plan view of the vehicle track)
