Factory Reverse Camera Retrofit

[snapdragon]

I have adapted the wiki destructions from Q7 to A8, but does anyone know what the Camera Height coding below means?
Mine is set to 04 +50mm on my second hand A8 unit.?

Camera Calibration
After performing service work, the calibration has to be performed too.
e.g.:
▪ Removing and Installing Rear View Camera (R189)
▪ Replacing Rear View Camera System Control Module (J772)
▪ after repair work performed on rear lid following an accident
▪ after a vehicle alignment
▪ after performing a repair at front or rear axle
▪
Prerequisites:
▪ Calibration Device (VAS 6350) and Distance Laser (VAS 6350/2) positioned as described in the factory repair manual.
▪ Vehicle must be standing on a firm and even surface.
▪ Tape measure
▪ Do not move the vehicle and do not operate the vehicle doors while performing the calibration.
▪ Rear Lid must be closed.
▪ Front Wheels straight, Steering Angle Sensor (G85) close to 0.0 ° in Measuring blocks 005.
▪ Ignition must be ON, Engine must NOT be running, you may connect a charger to keep the system voltage up.
▪ Back-Up Camera active and the MMI shows Back-Up Camera Video Signal.
▪ Make sure you do NOT have light reflections on the Calibration Device (VAS 6350).
▪ On vehicle vehicle’s suspension Level Control, set the Height to automatic.

Channel 005
[Read]
500 mm is the basis value of channel 005. Measure the heights between the Calibration Device (VAS 6350) and the ground surface
(e.g. 80 mm for OE, 4mm for cardboard), add 500 mm to it and enter the final value as new value (e.g. 500 + 4 = 504 mm).

Channel 004
[Read]
20000 mm is the basis value of channel 004, 2944mm (wheelbase for Audi A8 SWB (4E) or 3074 mm (wheelbase for Audi A8L (4E)).
Measure the Distance between the Calibration Device (VAS 6350) and the rear axle (e.g. 1500 mm), and subtract it from 20000 mm minus 3074 mm
enter the final value as new value (e.g. 20000 - 3074 - 1500 = 15426 mm).

To save your above adaptation save a new value of 1 to channel 001.

Can i ask what you were following, I just did a side by side from ross tech wiki and they are word for word the same.

The calibration is something I have never got round too but would like to one day, just need to buy the fablon as i have a sheet of white ad board ready

Just the ross-tech wiki for Q7 back-up cam, pasted into text editor and then I got the SWB & LWB wheelbase from wikipedia specs and put them in. I have figured the channel 05 is the height of the calibration target (The Audi dealer tool is 8cm deep a bit like a folding pasting table.)

Once I'm satisfied, I will send it to them for the A8 4E page.
I also attach PDF of Audi instructions.

Nice one, once I get the acc stuff out of the way I will have a crack at this too

I did my calibration today.
It took a few attempts and I amended the instructions above.
The main problem was not waiting a few minutes for the calibration.

I can now see the bumper in the bottom of the picture, whereas I couldn't before so that's great.

The only problem now, when I adapt values for colour, contrast and brightness it makes no difference. The values are saved, but the picture is a bit washed out, even extremes of range have no effect. Has anyone else change the brightness etc?...

[Delboy]

Is it by any chance also calibrating the light levels / contrast from the board.

Might by worth while doing again in different light conditions

It's a good question. Before calibration, I came to the conclusion that that must be a pre-requisite for adjusting the colour/contrast.

After calibration, all the levels were back at 50%, but changing them still makes no difference, even after turning ignition on and off. I'll keep looking into it.

[Delboy]

It does say to make sure there is no light reflections on the board which hints to the possibility of light levels having a significant impact on the process.

[Delboy]

Decided to go a bit blue Peter today and print out the calibration board on a4 and stick them all together.

If it doesn't work it's no big loss

Let me know if not - I have an A1 Plan printer
