Calibrating on a Slope? You Just Misaligned the Whole System.

Let’s talk about one of the most overlooked—but most critical—parts of ADAS calibration:

👉 The floor.

If your calibration is being done on an uneven, sloped, or cracked surface, guess what?

The entire system is off.It doesn’t matter how fancy your tablet is or what your scan tool says. If the surface isn’t level, the target’s not in the right place—and your calibration is wrong.

“It Looks Flat to Me” Isn’t Good Enough

OEMs specify exact tolerances for levelness. We’re talking millimeters of variation here. Not “close enough.” Not “eye-balled.”

If you don’t have a floor that’s laser-verified flat, then you don’t have a calibration space.You have a liability factory.

Mobile Calibrators: This Is Where Things Go Sideways (Literally)

We’re not trying to bash mobile—unless you’re setting up in:

• Sloped parking lots

• Gravel driveways

• Uneven shop entrances

• Slanted warehouse docks

Then yes, we’re calling it out.

You can’t fake level.You can’t “calibrate it out.”You can’t trust the scan tool to override gravity.

Final Word: If the Floor’s Off, Everything’s Off

Every measurement. Every sensor. Every angle.ADAS systems are precise. Your environment needs to be, too.

Flat floors aren’t optional. They’re foundational.
