Transforming Scratch Inspection of Glossy Emblems: A FORESIGHT STEREO Case Study
kotai20031. Introduction
An automobile emblem is, in a sense, the “face” of the car.
Even a slight scratch or defect can damage the brand image and may lead to customer complaints or recalls.
However, mirror-finished glossy surfaces reflect strongly, and scratches have been difficult to detect correctly with conventional general lighting and cameras.
2. The Customer's Challenges
On real quality assurance floors, we often hear challenges like these:
- “Reflections make the scratches invisible.”
- “We have no choice but to rely on inspectors' eyes, and accuracy varies.”
- “Our inspection costs keep rising.”
These were exactly the challenges facing the automotive parts manufacturer in this case.
3. The Solution with FORESIGHT STEREO
Here are the results of imaging with our FORESIGHT STEREO.
🔍 Comparison 1: General lighting vs FORESIGHT STEREO
- Top: Under general lighting, the scratches are barely visible.
-
Bottom: With FORESIGHT STEREO, even slight scratches stand out clearly.
“Scratches that were invisible under general lighting can be clearly seen with FORESIGHT STEREO.”
🔍 Comparison 2: Another pattern
- Top: Under general lighting, the scratches are barely visible.
- Bottom: With FORESIGHT STEREO, even slight scratches stand out clearly.
“Even fine line scratches on the emblem surface are clearly visualized.”
4. Case Results
In this test, we analyzed about 20 emblem images.
As a result, all of the scratches that had been overlooked by the conventional method were detected.
The benefits achieved were:
- Higher inspection accuracy
- Less working time for inspectors
- Lower risk of customer complaints through standardized inspection
These were all achieved.
5. Other Applications
This case involved automobile emblems, but similar challenges exist for other glossy parts:
- Chrome-plated parts
- Plastic exterior parts
- Glass surfaces
- Semiconductor wafers
FORESIGHT STEREO can be widely applied to quality inspection of glossy, highly reflective products.
