          On the importance of environment to machine vision system
          Author:Administrator   Published in:2019-12-18 16:50

            The environmental factors of machine vision system include object reflection coefficient, light, temperature, vibration and pollutants. The following Teo editor will give you a detailed introduction.

            1. Object reflection coefficient

            The reflection of an object can cause highlights and blur features. The lens shell and the baffle in the hood can reduce the high light phenomenon caused by light dispersion. The baffle plate is an opaque disc specially designed for the central aperture of the lens, which can limit the light reaching the sensor. Polarizing or scattering light source can also avoid the hot spot of object reflection.

            2. Light

            Light, especially monochromatic light, can improve the contrast of objects and maximize the quality of lens image. When using a black-and-white camera, contrast is very important and can be generated through the addition and subtraction process. In the addition process, monochromatic light source and camera lens filter match the media color of the analyzed object. The area around the object can reflect and transmit light, so it appears brighter than the object. This technology is very valuable in the application of gel and color liquid as backlit touch screen or particle detection.

            3. Temperature

            In high temperature environment, there may be problems due to the thermal expansion of optical elements in the lens. Not all lenses can adapt to temperature changes. When detecting hot objects, it is better to use a lens with a long working distance.

            4. Vibration

            Another factor to consider is vibration. It is usually necessary to mount the lens on a platform and desktop isolated from the camera to reduce vibration. The heavy camera lens always has a fixture. If the lens cannot be directly installed on the chopping board or similar isolated desktop, put the object loaded with the lens on a separate platform. Manipulator fixed on independent platform is often used to load camera and lens.

            5. Pollutants

            Contamination from industrial replacements can corrode lens surfaces. Extreme Environmental Optics (HEO) products are specially designed to provide high quality images even when exposed to harsh environments for a long time. Because its optical components are strictly sealed, HEO products can be used underwater, can resist corrosion, dust, and not be affected by machinery.

            The above is all about "environmental factors of machine vision system" to be shared by Teo editor today. TEO's products cover industrial and medical machine vision systems and products, mainly including: a full range of industrial cameras, special cameras for industrial image measurement, special crosshair cameras for laser cutting, special image collectors for micro imaging, ultra-high definition pathological micro imaging conference system, pathological micro image analysis and remote consultation system. Products are widely used in scientific research institutes, hospitals and schools, factories and mining enterprises, cultural relics appraisal units, criminal investigation and judicial, intelligent transportation and other industries.
