The importance of industrial lens in machine vision system
Nowadays, with the rapid development of science and technology, the industrial revolution is no longer at the simple level of industrial development. With the continuous improvement of human living needs, the exploration and pursuit of science and technology have become more and more in-depth. In the field of industrial automation, it has begun to enter the "robot era". The application of machine vision has been realized in the field of industrial testing, drug testing, manufacturing process monitoring, safety monitoring, high-precision measurement, identification and positioning, etc. The combination of industrial lens and industrial camera has greatly improved the efficiency and effect of industrial manufacturing.
Industrial lens is an eye in the field of machine vision. It has been playing the role of an eye since the detection of objects. It feeds back the detection situation to the industrial camera. Industrial lens is a lens with high-performance resolution. It adopts ultra-low distortion design technology to reduce the distortion rate and more truly reflect the image effect. Because the distortion technology can effectively reduce the reflection loss of the lens, reduce glare, increase contrast, effectively improve the color restoration and improve the image definition.
Industrial lens can be divided into long focus lens, short focus lens and zoom lens according to different detection requirements and measuring objects; According to the lens magnification, it can be divided into fixed magnification lens, manual zoom lens, manual fine adjustment lens, freeze frame fixed magnification lens and electric zoom lens; According to the resolution, it can be divided into 5 megapixels and 1000 pixels. Another lens adopts a unique parallel light path design technology, which has the characteristics of high resolution, large depth of field and low distortion. This kind of lens is telecentric lens, which meets the high requirements of lens distortion in machine vision.
The emergence of industrial lens has greatly accelerated the pace of the machine age. Machine vision replaces the difficult artificial vision, and effectively protects the interests and safety of human beings. In the special environment where people can not work normally, machine vision technology can be used to realize it, opening up a new field of science and technology. In the future course of industrial development, machine vision technology will gradually replace manual work, reduce labor costs and improve work efficiency.
The development of machine vision is closely related to the continuous updating of industrial lenses. Industrial lenses have many problems to face. For example, in the case of long-distance and weak light, it is necessary to overcome whether the lens can accurately grasp the target, and overcome the limitations of machine vision devices. The lens detection technology should be improved to the level of accurate detection in various backgrounds, and further improved to "artificial intelligence".
