p. 5

Introduction

The following flow chart helps to summarize the calibration process:

Reposition calibration 

pads or cameras and 

repeat process

Is 

calibrated 

360° image good? (no 

distortion, can clearly see 

calibration pads in 

image)

AVM components are 

installed in the vehicle

Calibration pads are 

placed around the vehicle

Camera images are 

captured and stored on 

an SD card in the vehicle

Images are transferred 

from the vehicle to a PC

PC Software performs calibration 

of the cameras. Calibration files are 

created and stored on the SD card.

SD card containing calibration 

files gets transferred from PC 

back to the vehicle

Operator loads calibration files and 

verifies quality of calibrated 360° image

Calibration is 

complete

No

Yes
