Machine vision, like the "eyes" of machine equipment, not only allows machines to see "objects" like humans, but machine vision functions are rapidly expanding to intelligent life with higher reliability, accuracy and automation than human detection. of all angles. From the identification of commodity barcodes to the automatic driving of unmanned vehicles, machine vision is like daily necessities, which are not deliberately mentioned but indispensable.
From the perspective of composition, the machine vision system is mainly designed to imitate human vision. The human visual system is composed of the eyeball, the nervous system and the visual center of the brain. Similarly, the composition of machine vision can be divided into two parts: hardware and software. The hardware is responsible for imaging, which is equivalent to the human "eye", mainly the light source and light source controller, lens and industrial camera; the software is responsible for image processing and analysis, which is equivalent to the human eye. "Visual Cortex".
The light source and light source controller assist during imaging (industrial cameras and lenses) and together provide the machine with an environment to "see". The lens collects the information of the subject, the industrial camera converts the optical signal into an electrical signal, and then the image acquisition card sends the image data output by the camera to the computer (industrial computer or PC), and the visual processing software in the computer writes appropriate algorithms by writing appropriate algorithms. Image processing and analysis are equivalent to the human "visual cortex" finally presenting the data we need to view.
The essence of industrial cameras is to convert optical signals into electrical signals, and this conversion and transmission requires various physical interfaces and transmission protocols to undertake. The common ones on the market are 1394 interface, USB2.0 interface, USB3.0 interface, GigE standard interface, CameraLink interface and CoaXPress interface. Among them, the GigE Gigabit Ethernet interface has an effective bandwidth of 100MB/s and a maximum transmission distance of 100 meters. It is the main camera interface currently on the market. Well-known manufacturers such as Basler, Hikvision Robotics, Daheng, ADLINK, and Cognex have launched industrial cameras that support the GigE interface.
