Toyota Corolla Cross: Before Starting Target Adjustment
BEFORE STARTING TARGET ADJUSTMENT
CAUTION / NOTICE / HINT
NOTICE:
When replacing the windshield glass of a vehicle equipped with a
forward recognition camera, make sure to use a Toyota genuine part. If a non-Toyota
genuine part is used, the forward recognition camera may not be able to be installed
due to a missing bracket. Also, the front camera system or automatic high beam system
may not operate properly due to a difference in the transmissivity or black ceramic
border.
HINT:
- Purpose of Forward Recognition Camera Optical Axis Learning
- If the installation position or orientation of the forward recognition
camera is changed due to it being replaced with a new one or the
windshield glass sub-assembly being replaced or removed and installed,
it is necessary to perform forward recognition camera optical axis
learning for the forward recognition camera to learn the driving
direction of the vehicle and its horizontal axis in order for each
driving support system to operate correctly.
- Characteristics of Forward Recognition Camera
- As the forward recognition camera recognizes targets using image
processing based on differences in contrast, when performing forward
recognition camera optical axis learning, if there are overhead
lights, windows, reflective objects, or high contrast objects behind
the target, the contrast between background objects may be detected
as high and may be misrecognized as a target.
- By blocking objects behind the target which may be misrecognized
as a target, the forward recognition camera can more easily recognize
the target and complete forward recognition camera optical axis
learning.

- Forward recognition camera optical axis learning may fail if
it is performed under any of the following conditions.
- Light Shining from Behind Target (Backlit)
As the target will appear dark to the camera
if the target is backlit, the contrast of the black and
white parts of the target will decrease and the target may
not be recognized.
- Target Partially Illuminated by Light from Windows
If the surface of the target is unevenly
illuminated, the contrast of the black and white parts of
the target will decrease and the target may not be recognized.
- Entire Target not Illuminated
If the target is placed in an area that
is dark, the contrast between the target and the background
will decrease and the target may not be recognized.
- Shadow of Target is Cast onto Wall
Make sure that the shadow of the target
is not cast onto a wall as this may cause a target recognition
error.
- Reflective Object on Target Surface
If an object, such as clear adhesive tape,
is attached to the target surface or if the target is laminated,
the target surface will reflect light. As the reflected
light will appear white to the camera, the target may not
be recognized.

- Border of Black and White Parts of Target are Blurry
or Distorted
If the borders of the black and white parts
of the target appear blurry to the camera, the detected
contrast will be low and the target may not be recognized.
- Target is Moving
If the target is moving, due to being blown
by the wind, etc., it may not be recognized.
- Target and Vehicle are not Level
If the target and vehicle are not level
when learning is performed, an incorrect center of the direction
of travel of the vehicle may be learned or the forward recognition
camera may not be able to detect the target.
