  • Dudu7 360 camera calibration parameter definitions.

I bought Dudu 360 camera along with Dudu7. Can you please help me to understand below parameters for 360 camera calibration. What values I need to enter

  1. Captain =
  2. Back suspension =
  3. Rearview mirror head =
  4. Rear back cali cloth =
  5. Front front cali cloth =
  6. What is Offset of all cameras
  7. And how to select lens type.

DUDU-HUANG Thanks, I have gone thru the calibration details in wiki dudu auto, but I don't understand half of the things ( which I mentioned above.

Do we need to enter only the values you have highlighted in red line box. If yes, what is the "Captian" value. What does it mean

This was all to complicated and time consuming to figure out.

I ended up buying an auto calibration matt and you place it once and no measuring is required. But proper placement on flat ground and no wind is crucial.

When we update an fyt 7862 to dudu6, is anything required to maintain 360 calibration?

I see this in config.txt "persist.syu.camera360 = 0“ I'm assuming changing 0 to 1 would keep the settings?

    HondaGuy thanks friend

    what does 'captain' mean?
    translating to english, I assume this means 'length'?

    EDIT: I didn't watch the whole video linked below until after I posted this. It's for a Reyes head unit, but it is using the same app as DuDu7. At 3:45, it tells you exactly what each setting (except for offset) is. Additional guide https://teyes.ru/pj/

    I just got my 11.5" Dudu7 head unit and I've been struggling with getting the 360 cameras calibrated. I found this video which appears to be the closest to having all the same settings as the Dudu7 360 app. I'm at work, so I won't be able to set up the calibration again for a day or two to test out these findings

    From what I could gather, these are the corresponding settings

    Captain = Car Length
    Front Track = Front wheel center to center distance
    Back Suspension = Center of rear wheel to rear bumper distance
    Rearview Mirror-Head = side camera to front bumper distance
    Offset - this is may be the distance from center that the front/rear camera is mounted, but it would not make sense for the side cameras there is no real center. It could also mean how far from actual length/width of the vehicle. On my truck, the front and rear cameras are set back about 15 cm from the end of the bumpers, so I'm going to try -15 offset. The side mirror cameras are 10 cm away from the body, so I'll try +10 offset. If those numbers don't seem to work, then I'll try setting the side offset based on distance from the side center of the truck. In this case, my front camera would have a 0 offset while the rear camera is mounted on the tailgate latch with a 4 cm offset.

    As for the cameras. I know the 2053 are more common cameras, while the 307 refers to the Sony 307 cameras which have better night vision. Usually the camera body has the number on it. If it doesn't, assume it's a 2053.

    Hope this info helps someone until Mekede can come out with a proper calibration guide
