Large PartsSince images are built in pieces, high-resolution images can be captured and transferred more quickly than an area camera of similar size. For example, a KEYENCE line scan camera can capture images up to 67 MP at speeds of 6.1 μs/line. Additionally, lighting is much easier. Only one line across a large part needs to be illuminated at once, rather than the entire target.

This differs from our BX/CX Series which falls off in uniformity when configuring units larger than 16 inches in width but provide minimal edge effect and a thinner package.

Line scan cameras build 2D images one line at a time, sort of like a scanner, and are useful when images of large products, cylinders, or continuous webs are needed. Either the camera or part must be in motion during capture.

Line scan cameras are used to capture images of moving parts one line at a time. Individual lines are stacked one atop the other in an image processing unit to ultimately build a 2D image. This style of image capture makes line scan particularly well-suited to inspections of continuous webs, cylinders, and large parts. Read on to find out why, or click here for more information:

LightLight selection is critical to any machine vision configuration; what the camera can't see, a machine vision system cannot inspect. The shape, size, and color of lighting, as well as installation distance and angle, can all be optimized to emphasize the features being inspected, and prevent any influences by the surrounding environment.

Machine vision has now become necessary in automation to improve efficiency and throughput by detecting defects and eliminating scrap.

LensLenses are used to focus the light onto the camera's image sensor. KEYENCE's high-resolution, low-distortion lens options ensure stable inspection across the whole image.

KEYENCE is proud to offer the most complete machine vision lineup of any automation supplier, from vision sensors with integrated lighting, to modular vision systems supporting area cameras, line scan and 3D cameras, and laser profilers. Award-winning hardware and advanced software algorithms combine to make KEYENCE machine vision the most stable solution for appearance and defect inspection, counting, positioning, measurement, and code reading applications; while built-in troubleshooting and maintenance tools speed up installation and decrease down-time.

Machine Vision refers to the use of industrial cameras, lenses, and lighting to perform automated, visual inspection of manufactured products.Machine vision provides a fast, reliable way to inspect parts inline. With machine vision, every part coming down a high-speed line can be imaged and inspected, to ensure 100% quality control.In the factory processes, machine vision can automate various inspections such as appearance inspections that check defects and faults, presence-absence checks, product type verifications, measurements, code readings.

Any industrial facility with a repetitive process can benefit from introducing vision. Machine vision has heavy presence in the automotive, plastics, food and packaging, medical device, and electronics industries, among others.

3D cameras are used to inspect features which can't be seen with a traditional camera, or require manual inspection. What differentiates them from other technologies is their use of height data to create contrast, instead of color, so that precise inspection can be completed even on low-contrast parts. KEYENCE's 3D cameras simultaneously capture 2D image data, without the need for external lighting, so that measurement can be performed in all three planes; X, Y, and Z.

CylindersWith a traditional area camera setup, a minimum of three images must be taken to see the full 360° surface around a cylinder. Additionally, due to the curved surface, part features may be distorted or difficult to evenly light. With a line scan camera, the entire cylinder is captured in one "unwrapped" image, free of any disfigurement.

The popular BL2 Series provides a high intensity, diffuse back-lit backlight source, primarily used for creating object silhouettes of high contrast or imaging through semi-translucent materials.
