Windshield Inspection Automation Using Intelgic IG5 AI and the Certainty Platform

Windshield inspection automation combines controlled material handling, robot-mounted imaging systems, specialized illumination, industrial machine vision cameras, synchronized image acquisition, and AI-based defect analysis.

Windshield Inspection Automation Using Intelgic IG5 AI and the Certainty Platform

Intelgic develops application-specific windshield inspection systems around its Certainty platform and IG5 AI model. The system captures the windshield under carefully engineered optical conditions, transfers the images into Certainty, analyzes them using IG5, and communicates the inspection result to production equipment and manufacturing software.

The solution can be configured for windshields at different manufacturing stages, including formed glass, laminated glass, printed glass, coated glass, and finished windshields containing functional components.

02 · Inspection Object

Understanding the Windshield as an Inspection Object

A windshield is a large, curved, transparent, laminated component. Its optical behavior changes across the surface because of curvature, glass thickness, viewing angle, printed borders, coatings, and reflections.

Because the windshield is not a flat surface and is highly transparent, inspection becomes challenging. Large windshields, especially those used in trucks, helicopters, and aircraft, require advanced imaging strategies to reliably detect defects.

Intelgic addresses this by using robot-mounted cameras and lighting systems that move across the windshield surface. The robot carries cameras and multiple light sources, allowing the system to inspect the glass from different angles. In some cases, multiple lights are used simultaneously from different directions to reveal subtle defects that are otherwise invisible.

An imaging system may simultaneously capture:

Front-surface features
Rear-surface features
Laminated interlayer features
Reflections from the inspection environment
Printed ceramic-frit regions
Background patterns visible through the glass
Attached components
Dust or contamination on either surface

The inspection system must create controlled and repeatable optical conditions before AI analysis begins.

03 · Grid Method

Grid-Based Optical Inspection Approach

In addition to conventional imaging, Intelgic uses a grid-based inspection method for optical distortion and surface deformation analysis.

A structured grid is placed as a controlled background behind or within the optical path. When the camera captures images of the windshield from multiple angles, any deviation, bending, or displacement of the grid lines is analyzed.

This approach helps detect
Optical distortion caused by curvature variation Localized waviness in the glass Manufacturing-induced deformation Lamination inconsistencies Viewing quality degradation

By comparing the expected grid geometry with the observed deformation, the system can quantify subtle optical defects that are difficult to detect using standard imaging alone.

04 · Defects

Windshield Defects and Features That Can Be Inspected

The exact inspection scope depends on whether a defect creates a measurable visual, optical, or geometric signal under the selected imaging conditions.

Windshield Defects and Features That Can Be Inspected
Scratches

Scratches can appear on the inner or outer glass surface. They may be straight, curved, isolated, or grouped. IG5 can be trained to analyze scratches according to:

LengthWidthContrastOrientationLocationInspection zoneSeverity

Robot-mounted cameras combined with directional and multi-angle lighting help reveal low-contrast scratches that are otherwise difficult to detect.

Chips and Edge Damage

Windshield edges may contain chips, shelling, cracks, rough areas, localized breakage, and incorrect edge finishing.

Because edges are difficult to capture with fixed cameras, robot-mounted imaging systems are often used to move along the perimeter and capture multiple viewing angles.

Cracks and Microcracks

Visible cracks may occur on the glass surface, near edges, around holes, or within specific formed regions. Their detectability depends on crack width, length, contrast, orientation, surface location, glass curvature, lighting direction, and camera resolution.

Multi-angle robot-mounted lighting is often used to highlight cracks that only appear under specific illumination directions.

Bubbles and Voids

Laminated windshields may contain bubbles, voids, or localized separation within the interlayer. Transmitted illumination combined with moving camera positions can make these conditions visible as variations in light transmission and texture.

Interlayer Defects
WrinklesFoldsBubblesForeign materialUneven laminationLocalized separationVisible interlayer distortionEdge-related lamination defects
Inclusions and Foreign Particles

Dust, fibers, glass particles, coating material, and other foreign matter may be located on a surface or within the laminate. The inspection system can analyze inclusions according to:

SizeShapeContrastLocationNumberProduct zone
Optical Distortion

Windshield curvature, forming variation, and lamination conditions can distort a reference pattern viewed through the glass. Intelgic uses a grid-based background approach for this inspection. When the camera moves across the windshield and captures images from multiple angles, deviations in the grid are measured to detect distortion.

Coating Inspection

Windshields may include solar-control, infrared-reflective, conductive, hydrophobic, or other functional coatings. Where the coating creates a detectable optical difference, the imaging system can identify missing coating, uneven coating, streaks, spots, contamination, coating boundaries, and localized appearance variation.

Shape and Contour Verification

Machine vision or 3D sensing can verify visible geometric characteristics such as:

05 · Robot Imaging

Robot-Mounted Camera Inspection System

A key feature of Intelgic windshield inspection is the use of robot-mounted cameras and lighting systems.

The robot carries
High-resolution camerasMulti-angle lighting systemsStructured illumination sourcesPolarized lighting modules, where required
This approach enables
Inspection of large curved surfacesFlexible viewing anglesClose-range high-resolution imagingAdaptive lighting direction controlEdge-to-edge coverage of the windshield

In many cases, multiple lights are used from different angles simultaneously to enhance defect visibility.

06 · Handling

Windshield Identification, Mechanical Presentation, and Custom Booths

Windshield Identification

Before inspection begins, the system can determine the correct windshield recipe using information from:

PLCMESProduction sequenceBarcode or QR codeOCRProduct markingsWork orderVisual part recognition
Mechanical Presentation and Handling

A windshield must be presented to the imaging system in a repeatable and stable manner. Intelgic can integrate the inspection station with:

Robot-based handling systemsExisting conveyorsGlass racksVertical transport systemsVacuum gripping systemsIndexing mechanismsDedicated inspection fixtures

The windshield may be inspected horizontally, vertically, or at a controlled angle depending on the application.

Custom Inspection Booth

Intelgic can develop a custom inspection booth to isolate the windshield from changing factory light and unwanted reflections. The booth may integrate:

Robot-mounted cameras and lightingEngineered illumination systemsControlled grid backgroundsMachine vision camerasMotion systemsCertainty softwarePLC and production-system interfaces
07 · Lighting

Multi-Angle and Grid-Based Imaging

Robot-mounted lighting enables dynamic angle variation to reveal defects that appear only under specific illumination directions.

A structured grid background is used to detect optical distortion by analyzing deviations in grid geometry across multiple camera positions.

08 · Cameras

Camera Configuration and Complete Surface Coverage

Intelgic selects cameras according to windshield size, required resolution, minimum defect size, and production cycle time.

High-resolution area-scan cameras
Line-scan cameras
Monochrome cameras
