What Is Screen Printing Machine?

Screen Printing, which is also known as silk screening. Screen printers use a silkscreen, a squeegee, and hinge clamps to screen print their designs. The ink is forced through the mesh using the rubber squeegee, the hinge clamps keep the screen in place for easy registration.

What Is CCD Visual Positioning System?

CCD visual positioning system is a visual motion control system developed for the needs of higher precision camera positioning identification, marking, engraving or cutting. It has the characteristics of high precision and high stability. It is mainly used in screen printing machines. CCD visual positioning system is a high-tech product used for industrial detection and identification. The core issue of production is the selection of industrial computer system, which can collect high-definition images of processed products and directly transmit them to the GPIO interface of the machine. Due to the rapid development of digital image processing and computer vision technology, more and more researchers have adopted cameras as the perception sensors of fully autonomous mobile robots. This is mainly because the original ultrasonic or infrared sensors have limited amount of information and poor robustness, while the visual system can make up for these shortcomings. The real world is three-dimensional, while the image projected on the camera lens (CCD/CMOS) is two-dimensional. The ultimate goal of visual processing is to extract relevant three-dimensional world information from the perceived two-dimensional image.

How Does CCD Visual Positioning System Work?

Due to the rapid development of digital image processing and computer vision technology, more and more researchers have adopted cameras as the perception sensors of fully autonomous mobile robots. The filter-based positioning algorithms of CCD visual positioning system mainly include KF, SEIF, PF, EKF, and UKF. The method of combining monocular vision and odometer can also be used. Using the odometer reading as auxiliary information, the coordinate position of the feature point in the current robot coordinate system is calculated by triangulation. The three-dimensional coordinate calculation here needs to be carried out on the basis of a delay of one time step.
