Area Scan vs. Line Scan
Understanding the advantages of scan systems
In certain applications, line scan systems have specific advantages over area scan systems. For example, inspecting round or cylindrical parts may require multiple area scan cameras to cover the entire part surface. However, rotating the part in front of a single line scan camera captures the entire surface by unwrapping the image. Line scan systems fit more easily into tight spaces for instances when the camera must peek through rollers on a conveyor to view the bottom of a part. Line scan systems can also generally provide much higher resolution than traditional cameras. Since line scan systems require parts in motion to build the image, they are often well-suited for products in continuous motion.
