Laser inspection is one of the most common uses for machine vision as it provides heightened quality control assurance with speed and precision unmatched by a human workforce. This technology introduces an opportunity for manufacturing quality, uniform and consistent products to a degree not easily achieved with human or other optical inspection systems.

Machine vision products encompass all systems and components designed and used for the application of computer
vision in industrial and manufacturing proceedings. These devices, when properly configured allow for image capture and the careful analysis of such a visual representation. The data collected may be recorded and displayed as such or direct mechanized action correspondingly in the workplace. Semiconductors, electronics, pharmaceuticals, automotive, healthcare, packaging, consumer products, textiles and several other industries utilize machine vision products in daily operations, especially in atmospheres requiring CNC machining or AVG equipment. These products mimic human vision to eliminate strain in these work environments and to promote safety in the exploration of hazardous materials. Though limited in comprehension and inference, machine vision can expand the magnification and viewable wavelength available with human vision. The applicability of machine vision products stems from this and their ability to perform a number of different tasks. Machines can be configured to sort, count, measure, inspect and evaluate parts and products in quick succession with high accuracy and precision. Completely integrated systems are often manufactured and sold as such, though individual components are also widely available to build custom machine vision equipment or to improve the capacity and capabilities of pre-existing tooling.
Vision
systems vary considerably to accommodate a wide range of industrial, commercial and even domestic applications. A few of the key components in nearly all systems include a vision
sensor, image capture or smart
camera, computer processor with vision software programmed in and both developer and user interfaces. Additional components may include lighting systems, connection cords, mounting elements and increased memory. As a product reaches an optical or pressure sensor which in turn triggers the camera and lighting where present to capture an image which best highlights features of interest. A device known as a frame grabber then digitizes this imagery and converts the camera output and enters the resulting data into the memory of the computer system where vision software. Programs vary, but most begin with reducing the noise or static visible in and image and simplifying the digital make-up of it. Mathematical algorithms then interpret the data based on pre-programmed criteria. A simplified user interface then presents this data to supervisors or archives it. As aforementioned, complete systems may be purchased as such or custom built to best suit a given application. Considerations when selecting a custom or standard machine vision product include inspection rate, product speed, number of cameras, processor speed, data storage capacities and overall dimensions.
