If your mobile Sharp system includes the
navigation option, you need to calibrate the hardware so that the readings are
accurate.
What you should know
- The calibration time (approximately 10-15 minutes) can vary based on
geographical location, environment, driving style, vehicle repositioning time,
proper execution of requested maneuvers, and driver experience with the
procedure.
- The procedure requires that you drive straight, backwards, and that you perform
several turns. You will also be asked to drive over hills. You need to locate a
suitable road, parking lot or large area where you can complete the procedure in
a safe way.
- No feedback is given when a maneuver is performed.
- You can perform the maneuvers in any order.
- There is no time limit to complete the maneuvers.
- If required, you can reposition the vehicle before each maneuver.
WARNING: For safety reasons, you must carry out calibration of AutoVu navigation away from any area with
motor vehicle traffic, with the assistance of another individual to identify and
avoid any hazards in the selected area. Genetec Inc. WILL IN NO EVENT BE LIABLE FOR
ANY DIRECT OR INDIRECT, CONSEQUENTIAL, INCIDENTAL DAMAGES OF ANY KIND, INCLUDING
ANY TRAFFIC ACCIDENT, ARISING OUT OF YOUR FAILURE TO FOLLOW THE FOREGOING
INSTRUCTIONS
Procedure
-
From the Equipment page in the Genetec Patroller™ Config Tool, select the
Navigation tab.
-
From the Calibration window, select if the odometry
signal comes from the vehicle’s VSS or from the odometry sensor. Read the
warning that appears and click I accept these terms to be
able to start the calibration process.
-
Click Start calibration.
This procedure is designed so that there is minimal need to touch the screen.
The instructions are read out loud and a sound signal indicates when to switch
to the next step. It is recommended that you perform this operation with a
co-driver and ensure that all necessary safety precautions are taken. The
following conditions must be met for the calibration to start:
- The antenna can receive the GNSS signal. If the vehicle is inside a
garage, move it to a clear sky area before starting the calibration
process.
- The vehicle engine is running and the transmission is in Park.
- The Sharp system is powered up.
-
Follow the instructions on the screen for a step-by-step description of the
calibration maneuvers. Perform the maneuvers until the window changes to the
next step or until the Calibration completed screen
appears. You can abort the procedure and start over at any time.
The following instructions are displayed for a pulse
calibration:
- Put the vehicle in park
- Stop the vehicle and put the transmission in Park until you hear
the sound signal and the next screen appears.
- Put the transmission in reverse
- No need to drive backward. Put the transmission gear in reverse
until you hear the sound signal and the next screen
appears.
- Put the vehicle in park
- Stop the vehicle and put the transmission in Park until you hear
the sound signal and the next screen appears.
- Drive forward at low speed
- Drive slowly forward until you hear the sound signal and the
next screen appear. Make sure that you do not go faster than the
indicated speed.
- Drive forward at 30 km/h
-
Drive forward at a speed of 30 km/h (20 mph) until you hear
the sound signal and the next screen appears. This step can
take time. It is important to continue until the step is
completed.
- Miscellaneous maneuvers
-
Execute the six maneuvers on the screen in any order. There
will be no prompt to go to the next one and no sound signal.
You can tap an image to zoom in and see it better. Tap again
to restore the view. If you have completed the six maneuvers
and the sensors are still not calibrated, do all the six
maneuvers again, in any order. To save time, you can combine
maneuvers. For example, you can drive straight on a small
slope, combining two maneuvers into one. Drive until the
Calibration completed screen
appears.
The calibration procedure might take some time because a large number of
samples are required for the wheel sensors to function correctly. Keep driving
the vehicle until the calibration completed screen appears.
-
Click Show sensor details anytime during calibration to view the
status of individual sensors:
- Gyro Z
- Measures the angular rotational velocity, or rotation speed that
determines the orientation of the vehicle.
- Accel X
- Measures the acceleration in the direction of travel (forward, backward)
- Accel Y
- Measures the acceleration perpendicular to the direction of travel (sideways).
- Accel Z
- Measures the acceleration up and down.
- Wheel ticks
- Measures the wheel rotation speed.
-
Click Close in the Calibration completed screen to
conclude calibration.
NOTE: If a problem occurs with the navigation system, you can enable verbose logs to
help Technical Support understand the situation. Go to the Advanced
page in the Traces section and put the
Navigation diagnostic logs to verbose.
Do not forget to turn it back off as it can take a lot of hard disk space. You can
click Abort at any time to cancel the calibration procedure.
Results
The AutoVu navigation is calibrated.
After you finish
If you change the position of the GNSS antenna or the AutoVu base unit, you must modify the layout
accordingly and recalibrate the system.
