The machine vision system is a set of vision systems established for machines or automated production lines based on machine vision technology. A typical machine vision system can be divided into two parts: "Vision" and "Sense". "Vision" refers to capturing image information through industrial cameras and other equipment, and "Sense" refers to processing and understanding these image information.
Next, let's get to know these parts and what problems LR-LINK can solve for customers.
"Vision"
The "Vision" part relies on a complete set of hardware solutions to display external information through imaging as a digital signal and feed it back to the computer. The main components include light sources, industrial lenses, industrial cameras, frame grabbers, and transmission cables.
The light source provides light for image acquisition to ensure that the captured image has sufficient brightness and contrast. As an auxiliary imaging device, the rational choice of the light source directly affects the quality of the input data and the application effect.
Industrial lenses are mainly responsible for beam modulation and signal transmission in machine vision systems. Generally, lens selection is based on factors such as camera interface, object distance, and shooting range.
The industrial camera can be said to be the "eye" of the machine vision system. It is responsible for capturing images and is the core device for image acquisition. It directly determines the resolution and image quality of the captured images.
The frame grabber is an important component connecting the two major sections of image acquisition and image processing. It converts analog image signals into digital signals and transmits them to the computer for subsequent processing. Stable capture without frame loss is an important factor in choosing a frame grabber. According to the interface type, the frame grabber can be divided into GigE frame grabber, USB frame grabber, VGA frame grabber and so on.
The transmission cable plays the role of transmitting signals, which can realize the communication between machine vision devices, and is the medium for completing image data transmission and camera control. Transmission cables will be affected by temperature, bending resistance, EMI and RFI interference, and factors such as cable material and impedance strength will directly affect the quality of the transmitted data.
"Sense"
"Sense" is a visual analysis system, which can be compared to the human brain, and is a key part of automatic processing in machine vision systems. The visual analysis system mainly relies on the software algorithm in the computer to perform advanced processing such as feature extraction, target detection, image recognition, and scene understanding on the received images, and complete tasks such as object classification, positioning, and tracking.
The machine vision system achieves comprehensive perception and analysis of image data by combining the two parts of "Vision" and "Sense". Nowadays, the variety of products in the machine vision industry is constantly enriched, and it is particularly important to choose the right equipment. "Avoid Frame Loss, Choose LR-LINK", as a professional network card solution supplier, LR-LINK has been outstanding in frame grabber solutions. After years of accumulation, it has independently developed stable and reliable 1G/2.5G/5G/ The 10G rate solution solves the problem of frame loss for customers and escorts the application of the machine vision industry.
