Engineering the Complete Vision System

📷
Industrial Cameras
Selection of appropriate cameras according to resolution, speed, sensor characteristics, and application requirements.
🔍
Optics & Lenses
Lens selection determines how the camera sees the object. Correct field of view, working distance, and optical characteristics are essential for reliable inspection.
💡
Industrial Lighting
Lighting is one of the most important parts of a vision system. We select lighting according to geometry, material, surface, and inspection objectives.
🖼️
Image Acquisition
We design the acquisition process to capture consistent, high-quality images reliably at the required production line speed.
⚙️
Image Processing
Images are processed and analyzed through algorithms to extract the precise information required by the industrial application.
Industrial Integration
The vision result is seamlessly integrated with PLCs, robots, machinery, or higher-level industrial software where required.
CAMERA TECHNOLOGY

Selecting the Right Industrial Camera

There is no single camera that is ideal for every application. GPLG evaluates the specific demands of each deployment to obtain the required image quality—not simply the highest specification available.

INDUSTRIAL LIGHTING
💡

Controlling the Image Before Processing It

Lighting determines what the camera can actually see. Different materials, surface finishes, and component geometries demand specific lighting techniques to highlight key features and eliminate unwanted visual noise.

🔳
Backlighting
Useful for high-contrast silhouettes, precise dimensional measurement, and edge profiles.
Ring Lighting
Suitable for general surface inspection and multi-directional component illumination.
Bar Lighting
Useful for larger inspection areas and producing targeted directional illumination.
🌐
Dome Lighting
Provides diffuse illumination to drastically reduce hot-spot reflections on curved or shiny surfaces.
👁️
Coaxial Lighting
Directs light along the optical axis, making it highly effective for flat, highly reflective surfaces.
🛠️
Custom Lighting
Purpose-designed lighting arrangements tailored specifically for unique or complex application constraints.
Core Vision Rule: Good vision starts with good illumination.
IMAGE ACQUISITION
⏱️

Capturing Consistent Images at Production Speed

Industrial inspection demands highly repeatable image acquisition. To prevent variability, image acquisition is precisely engineered around the physical dynamics of the actual production cycle.
