Using High-Speed Cameras to Expand Traditional Machine Vision

Using High-Speed Cameras to Expand Traditional Machine Vision

High-Speed Cameras and processing unit

For many industrial automation applications, machine vision has been successfully used as a process control tool. To guide, examine, or identify items as they travel along manufacturing lines, this technology traditionally includes commercial off-the-shelf (COTS) imaging sensors, lighting modules, and CPUs. Machine vision systems are quicker, more precise, and repeatable than human operators, which improves product quality, reduces scrap rates, and boosts productivity in demanding industrial situations.

High-speed digital imaging enhances the advantages, potential, and applications of machine vision even further while maintaining the operational advantages that are now apparent. High-speed cameras enable machine vision in demanding applications that demand real-time analysis or lengthy record times, such as semiconductor manufacturing, space shuttle launches, railway inspection, and more, thanks to their high resolution, quick frame rates, and streaming features. Due to these limitations, traditional vision systems are unable to acquire information from high-speed machine vision systems, which allows them to shine light on processes that are too small or too rapid for the human eye to perceive.

Key Features of High Speed Machine Vision Camera

Traditional machine vision cameras and high-speed machine vision cameras have some key differences. High-speed cameras integrate customized complementary metal-oxide semiconductor (CMOS) sensors in place of COTS or charge-coupled device (CCD) sensors. When created exclusively for high-speed applications, CMOS sensors offer unparalleled speed and sensitivity, enabling more thorough inspections and higher yields in machine vision applications including defect identification, part measurement, and more. Even at challenging frame rates, high-speed machine vision cameras with CMOS sensors and multiple megapixels produce remarkable image quality.

Resolution

Vieworks' area scan high speed camera have resolutions ranging from 0.4 megapixel to 604 megapixels at up to 340 frames per second, making it ideal for a variety of applications such as flat panel inspection, semiconductor inspection, electronic component inspection, and factory automation.

Light Sensitivity

The greater the image detail, which is crucial in applications requiring a microscope, the smaller the pixel size generally is. A high native ISO is achieved by the small pixel sizes of CMOS sensors. Due to this, high speed cameras are able to capture outstanding image quality despite the low exposure durations required for high-speed machine vision applications.

Exposure Time

The exposure times of Vieworks high speed cameras can be as low as 1 microsecond. Together with its high sensitivity to light and small pixel size, this feature effectively stops fast-moving objects without creating motion blur.

Dynamic Range

When an image has several shades or when a subject is nearly the same colour as its background, dynamic range is important. The more shading definition a camera's sensor can detect, the higher its dynamic range.

High-speed machine vision cameras use copper CoaXPress (CXP) cable technology in addition to highly specialized sensors to transport enormous volumes of data to compatible, industry-standard backend frame grabbers in real time. The time-consuming process of saving data to the camera's limited RAM before uploading it to a computer is avoided by the ability to stream data instantly. These streaming cameras also offer longer recording applications in aerospace, such as rocket dynamics, airplane dynamics, and ballistics, to mention a few, when paired with commercially available DVR systems.

Manufacturers can obtain imaging with improved resolution and recording accuracy thanks to high-speed cameras. These features speed up manufacturing lines, boost output, remove bottlenecks, and lower per-unit costs. Additionally, these streaming cameras enable the capturing of targets at the nanoscale scale that would normally be challenging to view, let alone analyze, using conventional machine vision cameras. This allows machine vision to transition from a process control tool to a diagnostic tool. Machine vision is thus gaining popularity in a variety of sectors, including the health sciences, semiconductor production, the pharmaceutical industry, and more.
