Line scan vs. area scan technology: choosing the right solution for your application
When it comes to industrial imaging, understanding the differences between line scan and area scan technology is crucial for selecting the right solution. Here’s a breakdown of how each technology works and their intended use cases.
Line scan technology
- How it works: Builds images line-by-line as objects move past the sensor, ideal for fast or continuously moving objects.
- Best use cases: Inspecting continuous materials like webs and textiles, cylindrical objects, complex surfaces, and large parts.
Area scan technology
- How it works: Captures the entire image in a single snapshot, ideal for static or objects moving at a moderate pace.
- Best use cases: Inspecting parts on a production line where items remain stationary for short periods.
Enhance quality control with image overlap technology
The In-Sight 3800 Line Scan uses advanced image overlap technology to deliver full-coverage, highly detailed inspections, ensuring superior quality control on fast-moving production lines.
- Improved accuracy: Capture overlapping sections for complete inspection coverage, reducing the risk of missed defects and ensuring consistent product quality.
- Seamless high-speed inspection: Perfect for high-speed production environments, ensuring no areas are overlooked, even with fast-moving lines.
Simplify deployment with a unified software and complete toolset
The In-Sight 3800 Line Scan uses In-Sight Vision Suite, a common platform that simplifies how you build, deploy, and manage vision applications. With a consistent interface across all In-Sight devices, users can cut down on training, accelerate setup, and expand automation efforts with ease.
From basic inspections to specialized applications, the In-Sight 3800 Line Scan brings AI and traditional vision tools together in one high-performance system. Use the tools individually for simple tasks, or combine them to tackle more complex automation challenges.
With powerful AI tools running directly on the device, the In-Sight 3800 Line Scan enables real-time decision-making and easy setup, even for users without prior experience.
- Segmentation: Highlight and separate defects, regions, and objects from complex parts and backgrounds.
- Classification: Identify and sort parts based on unique features or characteristics.
- Optical character recognition (OCR): Read characters on reflective, low-contrast, and non-flat surfaces.
The In-Sight 3800 Line Scan also includes a full library of industry-proven, traditional vision tools and algorithms – such as Measure Distance, Pixel Count, Count Patterns, and Math and Logic tools – providing reliable performance for a wide range of inspection tasks.
Applications
Built for demanding applications across all industries
From detecting defects on continuous webs to inspecting cylindrical surfaces and complex patterns, the In-Sight 3800 Line Scan solves a range of factory automation applications while delivering reliable performance at the fastest speeds.
Optical character recognition (OCR)
Extract and read text, such as lot codes and expiry dates, from rotating or curved surfaces to ensure accurate product tracking and regulatory compliance.
Defect detection
Identify defects on wide-format items to maintain high quality standards for printed media and other materials.
Presence/absence detection
Check for the presence or absence of critical features across multiple areas on large objects to confirm proper assembly.
Continuous web inspection
Detect coating gaps or voids on continuous web materials to find and correct quality issues during the manufacturing process.
Barcode reading
Accurately decode barcodes on large parts for reliable tracking and traceability throughout production.
Measurement
Unwrap and measure circular or curved parts to ensure precise dimensions and proper fit in final assemblies.
