What is a Line sensor camera?

A line sensor camera is a specialized camera primarily used in industrial applications, designed to capture linear images. This camera features a sensor array arranged in a one-dimensional line, allowing it to scan the surface of an object in a lateral motion to generate images. By continuously passing objects through its field of view, it can rapidly acquire detailed information about their surfaces, enabling high-speed image processing.

Line sensor cameras are widely utilized in manufacturing for quality control and inspection tasks, particularly effective in print inspection, dimensional measurement of parts, and defect detection. When combined with lasers, they can also be used for 3D shape measurement, accurately capturing surface contours and shape variations.

Moreover, line sensor cameras are optimal for applications requiring fast data acquisition and situations where broad information needs to be gathered simultaneously. Their use is expanding across various sectors, including automotive, food processing, and electronics, contributing to enhanced efficiency and quality in manufacturing processes.

Application of Line sensor camera

１．Print Inspection
Line sensor cameras are used in printing processes to verify print quality. They detect printing errors in text and images in real-time, playing a crucial role in maintaining quality standards.
２．Dimensional Measurement of Parts
In manufacturing, line sensor cameras are employed to accurately measure the dimensions of parts. This is particularly important in the automotive and electronics industries, where precision in size is essential.
３．Surface Defect Detection
Line sensor cameras are used to identify scratches and defects on product surfaces. They are especially effective in inspecting metals and plastics, allowing for immediate detection of surface anomalies.
４．Packaging Inspection
In the packaging process for food and pharmaceuticals, line sensor cameras verify the accuracy of labels and the integrity of seals. This ensures that consumers receive safe products.
５．3D Shape Measurement
Line sensor cameras, when combined with lasers, can be used to measure the three-dimensional shape of objects. This enables precise measurements of complex-shaped products, improving design accuracy.

These examples demonstrate the contributions of line sensor cameras to quality control and process improvement across various industries.
