Traffic Sign Recognition System Calibration
Traffic sign recognition is a common advanced driver assistance system which uses forward facing cameras to help simplify driving by automatically recognising road signs and displaying them, and what they mean on your dashboard or display screen.

Lancashire ADAS provides a calibration service for all ADAS features, including traffic sign recognition, so you can rest assured that your systems are operating correctly and simplifying the driving experience as much as possible.
What is traffic sign recognition?
Traffic sign recognition systems use cameras to scan for road traffic signs and analyse them, before displaying the information on the dashboard/driving display. This is designed to help drivers understand things like the speed limit in their zone, speed camera locations, and overtaking restrictions. It can act as a reminder to drivers who may have missed certain signs, helping them to remain in line with traffic laws and avoid collisions.
People often ask if ADAS calibration is really necessary, because they don’t realise how finely tuned these systems need to be in order to operate correctly. The truth is, even the slightest collision, minor repairs, or body modifications can throw ADAS cameras and sensors out of alignment, which causes inaccurate readings.
Why is accurate traffic sign recognition important?
Accurate traffic sign recognition is vitally important because it increases driver awareness, reduces accidents, supports autonomous vehicles, and can even improve traffic flow.
However, it’s important to note that ADAS keeps us safe primarily by being accurately calibrated and aligned. Misaligned cameras, or sensors which are not finely tuned, can actually lead to dangerous situations.
Accurate traffic sign recognition helps simplify the driving process, by clearly displaying speed limits, road rules, and more.
On the other hand, inaccurate traffic sign recognition could lead to wrongful readings, meaning your dashboard may display an incorrect speed limit, or tell you the wrong rules for the road you’re on! ADAS calibration is vital to keep these systems functioning optimally.
Key components of traffic sign recognition system calibration
Expert ADAS technicians calibrate your vehicle safety systems primarily by looking at the following components:
Front-facing camera - Traffic sign recognition cameras are almost always situated on the inner of the front windshield, mounted near or on the rear view mirror to capture images of traffic signs in real time. Calibration ensures that these cameras are able to capture clear and accurate images.
Image processing software - The software installed in your vehicle processes the images captured to identify each traffic sign. This software needs to be calibrated and tested by professionals to ensure it is identifying signs accurately and quickly.
Dashboard display - To ensure safety, our engineers will check that information is being displayed correctly, clearly, and quickly on your display. This guarantees that you are provided with the correct information in real time.
ADAS windscreen calibration is a highly specialised job which can’t be carried out by a non-professional. It requires specialist testing equipment and qualifications.
