GPT-4v
Enables access to OpenAI's vision
model for uploading and analyzing
images.
System Prompt
Your task is to identify key
information on a vehicle
component. Please verify if
"INFORMATION" is visible.
For each component, the relevant
CoP information is inserted in the
task instead of “INFORMATION.”
Temperature
{0 – 1}
0
With a value of 0, the model works
very deterministically. Values closer
to 1 increase the creativity of the
model, which can lead to unwanted
fantasies and be inappropriate for
the CoP check.
A dedicated bot was programmed for the veri昀椀cation of component IDs (homologation labels). The bot con昀椀guration was set based on the homologation process and remained consistent for each detection of the component
ID (homologation label).
Equipment
• Camera (Canon EOS RP + RF 24-105mm F4-7.1 IS STM lens (Canon Europa N.V., 2024): The camera is operated
in automatic mode, which automatically adjusts parameters such as exposure time, ISO 昀椀lm sensitivity, exposure
compensation, as well as aperture and shutter speed.
• 2 industrial lamps (SLV 1004076 NUMINOS PHASE (DEL-KO GmbH, 2023) with 10 different adjustment levels.
• Tripods for mounting the lamps and camera.
• Lux meter: Used for measuring brightness (Sauter Luxmeter SO 200K) (Rose, 2024).
Test series
As part of the PoC, an experiment is conducted in which all parameters from the experimental design (see Table
number of
5) are tested across all component classi昀椀cation classes (section 4.2).

The evaluation takes place in the assembly. The insights gained in the PoC will be 昀椀nally evaluated at the
production line.
