Work Procedure

Calibration must be performed after removing/replacing the cameras, removing parts (e.g. front grille, door mirror, and others) mounted on the cameras, or replacing the around view monitor control unit.
The use of CONSULT is required to perform calibration or writing of calibration results to the around view monitor control unit.
Align the white lines on the road near the vehicle at the boundary of each camera image by this camera calibration. The white lines far from the vehicle may not be aligned at the boundary of each camera image. The farther the line, the greater the difference is.
Following the flowchart shown in the figure below, perform the calibration.

CAUTION:

When around view monitor control unit is replaced, Write the calibration data before performing camera image calibration. Refer to Work Procedure .

CHECK AROUND VIEW MONITOR SCREEN
1. Check that there is no indication of "Incomplete calibration".

  NOTE: View in the incomplete calibration state is indicated by " " on the around view monitor.
Is the "Incomplete calibration" display visible?

YES>>

GO TO 3.

NO>>

GO TO 2.
PERFORM SIMPLIFIED CONFIRMATION BY BIRDS-EYE VIEW SCREEN
1. Check the gap between each camera image on a birds-eye view screen.
Does the gap between each camera image exist?

YES>>

GO TO 3.

NO>>

Work End.

PREPARATION OF TARGET LINE 1

NOTE:

If a target line is narrow, it is hard to confirm it with around view monitor screen. The width of the target line recommends an approximately 5.0 - 10.0 cm (1.97 - 3.94 in).
It is easy to confirm a target line on a around view monitor screen when draw a target line with a color opposite to a working floor.
Example:
- Floor is blue: target line is yellow
- Floor is green: target line is red

Preparation of target line 1

Hang a string with a weight as shown in the figure, below. Put the points FM0, RM0 (mark) on the ground at the center of the vehicle front end and rear end with white packing tape or a pen.

	Thread		Weight		Point FM0 (mark)
	Point RM0 (mark)		Packing tape (to fix the vinyl string)		Vinyl string

Route the vinyl string under the vehicle, and then pull and fix it on the point approximately 1.0 m (39.9 in) to the front and rear of the vehicle through the points FM0 and RM0 using packing tape.

A	: Approx. 1.0 m (39.4 in)

Put the points FM and RM (mark) 75 cm (29.5 in) from the points FM0 and RM0 individually.

Courtesy of NISSAN

A	: Approx. 75 cm (29.5 in)

Route the vinyl string through the points FM and RM using a triangle scale, and then fix it at approximately 1.5 m (59.0 in) on both sides with packing tape.

A	Approx. 1.5 m (59.0 in)

Put the points FL, FR, RL, and RR (mark) to both right and left [vehicle width / 2 + 30 cm (11.8 in)] from the points FM and RM.

Courtesy of NISSAN

A	: Approx. 30 cm (11.8 in)

Draw the lines of the points FL - RL and FR - RR with vinyl string, and fix it with packing tape.

Put a mark on the center of each axle

, draw vertical lines to the lines of the points FL - RL and FR - RR from the marks on the center of the axle using a triangle scale, and then fix the lines using packing tape.

PERFORM "CALIBRATING CAMERA IMAGE"
1. CONSULT
  1. Select "CALIBRATING CAMERA IMAGE" in "Work Support" mode of "AVM".
    NOTE: In random order, perform the operation for all cameras for which un-match display appears.
    - Front camera: "CALIBRATING CAMERA IMAGE (FRONT CAMERA)"
    - Side camera RH: "CALIBRATING CAMERA IMAGE (PASS-SIDE CAMERA)"
    - Side camera LH: "CALIBRATING CAMERA IMAGE (DR-SIDE CAMERA)"
    - Rear camera: "CALIBRATING CAMERA IMAGE (REAR CAMERA)"
  2. Perform "CALIBRATING CAMERA IMAGE" as per the following procedure.
    1. On the adjustment screen of each camera, adjust the parameter by touching the "AXIS X", "AXIS Y", and "ROTATE" to place the calibration marker shown on the camera screen on the target line drawn on the ground.
    2. On the adjustment screen of each camera, operate "+" and "-" of "Magnify/Reduce", so that images on screen of target line and calibration maker are aligned.
  3. Touch "APPLY" on the CONSULT screen. "Writing..." is displayed and adjustment results are shown on the camera screen.
    CAUTION:
    Check that "Writing..." is displayed. Do never perform other operations while "Writing..." is displayed.
  4. Touch "OK" on the CONSULT screen. "PRCSNG" is displayed and adjustment results are written to the around view monitor control unit.
    CAUTION:
    Check that "PRCSNG" is displayed. Never perform other operations while "PRCSNG" is displayed.

PERFORM "FINE TUNING OF BIRDS-EYE VIEW" (1)

CONSULT

Select "FINE TUNING OF BIRDS-EYE VIEW" in "Work Support" mode of "AVM".

Perform "FINE TURNING OF BIRDS-EYE VIEW" as per the following procedure.

Courtesy of NISSAN

CAUTION:

Perform adjustment operation slowly because approximately 1 second is required for changing image on screen.

NOTE:

Touch "SELECT" on CONSULT screen and select camera position for adjustment.

Operate "+" and "-" of "AXIS X", "AXIS Y", and "ROTATE", so that images on screen of target line on the ground and marker are aligned between each camera.
Operate "+" and "-" of "Magnify/Reduce", so that images on screen of target line on the ground and marker are aligned between each camera.

Touch "APPLY" on the CONSULT screen. "Writing..." is displayed and adjustment results are shown on the camera screen.
CAUTION:
Check that "Writing..." is displayed. Do never perform other operations while "Writing..." is displayed.
Touch "OK" on the CONSULT screen. "PRCSNG" is displayed and adjustment results are written to the around view monitor control unit.
CAUTION:
- Check that "PRCSNG" is displayed. Never perform other operations while "PRCSNG" is displayed.
- After touching the "OK", never touch screen other than the "BACK".

NOTE:

The adjustment value is cancelled in this mode by performing "Initialize Camera Image Calibration".

Is the gap between the each camera image normal?

YES>>

Work End.

NO>>

PREPARATION OF TARGET LINE 2
1. Draw target line 2 at the position of the approximately 1.0 m (39.9 in) outside from target line 1 which established by procedure 2.
