About the AVM
The inView 360 Fusion Around Vehicle Monitoring (AVM) system provides drivers with a real-time, 360°
picture of the area around their vehicle to help eliminate blind spots, improve pedestrian safety, prevent
vehicle damage, and avoid liability costs.
To achieve the 360° picture, 4 images are captured from cameras positioned in the front, left, right, and
rear of the vehicle. These images are then transferred to a computer and calibrated using software. Once
calibrated, the images are transferred back to the vehicle and viewed on a monitor mounted in the cab of the
vehicle.

inView 360 Fusion Calibration Guide PREPARATION
Physical Environment
Ideally, calibration should be performed in a well-lit, bright shop with adequate space around the perimeter of
the vehicle. There should be a minimum of 80 inches all around the vehicle.
Calibration can be completed outside, but only on a level, paved surface. Calibrating in the rain or snow is not
recommended as this can cause distortion (snow or rain on the camera lenses).
Installing the Calibration Tool
The Seon Calibration Tool comes on the supplied USB drive included in your calibration kit. To install, simply
unzip the calibration tool folder and move the contents to a directory on your computer.
The folder will contain several sub folders and les. Ensure that your folders look like the ones in this
example:

Once the AVM components have been installed, the next step is to place calibration pads around the vehicle.
Measure your vehicle length
Using a long tape measure, capture the length and width of the vehicle and
record the values. These values will be used in the calibration software later on
in the process.
Place your calibration pads
1. Start by placing measuring tapes in front of the vehicle, starting from the front of the tires and going
forward (Tapes 1 & 2).
2. Position tape 3 squarely in front of the vehicle’s bumper. Use a square ruler to ensure that measuring tape
3 is perpendicular with tapes 1 & 2.
Note
The furthest tips of the vehicle should be considered in your
measurement, including the bumpers. However, external accessories
like plows or winches should NOT be measured.

3. The following values will help you determine where to place your calibration pads. Refer to your
(approximate) vehicle length in the table, and record the Horizontal (H) and Vertical (V) values.
Vehicle Length in Feet Vertical (V) and Horizontal (H) Spacing in Inches
20’ 25”
25’ 30”
30’ 40”
40’ 35” - 40”
45’ 40” - 50”
4. Place tape 4 a distance of “V” in front of the vehicle, again ensuring that it is perpendicular to tapes 1 & 2.
This is your Vertical distance

5. Place the calibration pads a distance of “H” in front and to the left or right of the vehicle. This is your
Horizontal distance
6. Repeat the same procedure for the rear of the vehicle. Here’s what the vehicle would look like from above,
when calibration pads are place properly.

About Horizontal and Vertical Values
Since different vehicles have varying heights and widths, the values may not work for your vehicle shape. In
order to properly calibrate the AVM system, you will need to calibrate using the initial recommended values,
then re-adjust the pads or cameras, and repeat calibration until you have the desired image.
Ultimately, the calibrated image should be clear, distortion free, and you should see the calibration pads
clearly on the in-cab monitor. Take a look at the following images side by side:
Image A has some distortion on the calibration pads in the rear of the vehicle. You can see that there is a
“ghosting” effect. Image A would need to be re-calibrated.
In image B, you see that the image has no distortion and the pads can be made out clearly in the image.

PREPARING IMAGES FOR CALIBRATION
After you’ve placed down your pads and recorded your measurements, you’re ready to capture the images from
the cameras and transfer them to your computer for calibration.
Capturing AVM Images
To capture the images, you’ll need to do the following:
1. Insert SD card (with SAV-BOOT) into the Electronic Control Unit (ECU).
2. Power up the ECU. The ECU detects the SD card on power up, and displays the system menu.
3. Use the AVM remote control to select the Calibration option, then press the OK button (indicated on the
remote by a symbol). Next, select Camera Capture and press OK again.
4. The AVM copies 4 les to the SD card.
5. When copying is done (OK appears on the screen), power down the unit, and remove the SD card.
Transferring Images to PC
Once you’ve captured the raw images on the SD card, you’ll need to transfer them to your PC for calibration.
To do this:
1. Insert the SD card (with USB adapter, if required) into the PC.
2. Navigate to the SD card location. Cut the following 4 les:
•FRONT.bin
•RIGHT.bin
•LEFT.bin
•REAR.bin

Understanding Pixel Pitch
In the Vehicle Information box, you’ll see several values on the right-hand side. These values represent the
vehicle’s “pixel pitch”.
Think of pixel pitch as the vehicle’s “zoom level” when looking at the vehicle from above. A higher pixel pitch
means you can see more of the area around a vehicle. A lower pixel pitch means you see less.

inView 360 Fusion Calibration Guide
p. 14
inView 360 Fusion Calibration Guide PREPARING IMAGES FOR CALIBRATION
In the following example, we see that a low pixel pitch results in an image that appears zoomed in. When
you select a high pixel pitch, the image appears zoomed out, and you can see more of the area around the
vehicle (i.e., the vehicles in the surrounding area).
When you enter your vehicle length and width, the calibration tool computes a range of values based on
your vehicle’s dimensions. As you change the width and length, the pixel pitch range also changes. When
you change the set value, the pixel pitch preview image also changes. As mentioned, a low pixel pitch value
shows less area around the vehicle. A higher value shows more.
Low Pixel Pitch = “Zoomed In” High Pixel Pitch = “Zoomed Out”

To preview a different pixel pitch value, enter a number between the min and max values, and click .
The preview image will change to reect the new value.
About View Modes
Pixel pitch values are congured differently depending on the calibration tool’s “View Mode” When setting
pixel pitch values, you have set and range values for two different modes:
•NT mode,
•ST (FFT) mode.
Notice also that there is a View Mode selector. In the selector you have the option of choosing NT, ST or
ST(FFT) view modes. But what is view mode and how does it affect the calibration procedure?

inView 360 Fusion Calibration Guide
p. 16
inView 360 Fusion Calibration Guide PREPARING IMAGES FOR CALIBRATION
The view mode you calibrate in depends on how you wish to position the AVM monitor in the vehicle. The
following images will help illustrate the effects of view mode:
If you are going to mount the monitor in a landscape position, then you’ll need to calibrate your cameras in
NT (normal top) mode. If you wish to use a portrait position, then you’ll need to calibrate for in ST (separate
top) mode.
Note that a third option - ST(FFT) (Side Top Full Front Top) works in conjunction with ST mode. FFT gives
you a full screen view of the 360°image. This option is only available if you choose to calibrate the cameras
in ST mode. The FFT image will not work if you calibrate in NT mode.
When you launch the calibration tool, the view mode will be set to NT, which is the default. To switch view
modes, click the drop-down menu and select the mode you want to calibrate for.
Setting pixel pitch for NT or ST Mode
The procedure for setting pixel pitch for
NT or ST mode is the same, as they share
the same data elds. To set the pixel pitch
for either of these modes:
1. Select the appropriate view mode from
the drop-down menu.
2. In the NT Pixel Pitch eld, enter a
value between the min and max range,
as calculated by the application.
3. Click . A preview of the pixel
pitch will appear in the window below.

Setting pixel pitch for ST(FFT) Mode
The procedure for setting pixel pitch for
ST(FFT) mode is similar to above:
1. Select ST(FFT) view mode from the
drop-down menu.
2. In the FFT Pixel Pitch eld, enter a
value between the min and max range,
as calculated by the application.
3. Click . A preview of the pixel
