Large vans often lack the reference points that sedans have,
therefore the camera should be lined up so that sections 7
and 9 barely pass the dashboard and then fine tuned accord-
ing to the user's preference.
II、Calibrating for FCWS
Once the GDR 190 has been installed and turned on, the
user will be prompted to complete an initial image calibra-
tion, and the camera will automatically determine the ve-
hicle's center position. During calibration, the GDR 190 will
automatically recognize the lane that the vehicle is travel-
ing on (indicated by the solid green lines) and extend the
two reference lines until they intersect. The point of inter-
section will be used as the screen's center position.
After Calibration Is Complete
1. Intersection of the two extended lines will be marked
on-screen with a green cross.
