Principle and Application of Automatic Image Detector

Nowadays, there are all kinds of testing equipment in all walks of life, such as chemical analyzer, environmental detector, 3D laser scanner, mapping instrument, length meter, industrial online and process online controller, etc. Three coordinate detector, image detector and projector are special length measuring and testing instruments for measuring geometric dimensions and geometric tolerances.

The automatic image Measuring Instrument is a high-precision optical image measuring instrument consisting of a high-resolution CCD color lens, a continuous zoom objective lens, a color display, a video crosshair display, a precision grating ruler, a multi-function data processor, a data measurement software and a high-precision workbench structure. Its application fields are also quite extensive: machinery, electronics, molds, injection molding, hardware, rubber, low-voltage electrical appliances, magnetic materials, precision hardware, precision stamping, connectors, connectors, terminals, mobile phones, household appliances, computers (computers), liquid crystal televisions (LCD), printed circuit boards (circuit boards, PCB), automobiles, medical devices, clocks, screws, springs, instruments, gears, cams, threads, radius templates Thread template, wire and cable, cutter, bearing, screen, test screen, cement screen, screen plate (steel mesh, SMT template), etc.

With the progress of science and technology and the continuous improvement of technology, the image detection market has been basically covered by the full automatic image detector, which is an artificial intelligent modern optical non-contact measuring instrument developed on the basis of digital image detector (also known as CNC imager). It inherits the excellent motion accuracy and motion control performance of digital instruments, integrates the design flexibility of machine vision software, and belongs to the optical dimension detection equipment of the Z frontier. The full-automatic image detector can conveniently and quickly perform 3D coordinate scanning measurement and SPC result classification, meet the increasingly prominent requirements of modern manufacturing industry for size detection: faster, more convenient and more accurate measurement needs, and solve another bottleneck technology in the development of manufacturing industry.

Automatic image detector is an advanced stage of image measurement technology, which is highly intelligent and automatic. Its excellent software and hardware performance makes the coordinate size measurement convenient and comfortable. It has the automatic learning function based on machine vision and process control. Relying on the high-speed and accurate micron level positioning of digital instruments, it can self-learning and memorizing the path of the measurement process, focusing, point selection, function switching, manual correction, light matching and other operating processes. The full-automatic image detector can easily learn all the operator's practical operation processes, and achieve artificial intelligence by combining its automatic focusing, area search, target locking, and edge extraction fuzzy operations. It can automatically correct the offset caused by workpiece difference and displacement difference to achieve accurate point selection, with high-precision repeatability. Thus, the operators can be freed from the monotonous operations such as accurate visual alignment, frequent point selection, repeated displacement, function switching, and increasingly heavy tasks to be tested, and improve the efficiency of workpiece batch testing hundreds of times to meet the needs of industrial sampling inspection and mass testing.

The automatic image detector has three methods: manual measurement, CNC scanning measurement, and automatic learning measurement. Fluorescent penetrant pipeline detection can combine the modules of the three methods for composite measurement. It can scan and generate a bird's-eye image map to achieve the full screen target traction of "where to go". The generated graph of the measurement result is synchronized with the image of the image map. It can click the graph to automatically return to its original position and enlarge the full screen eagle's eye. Any measured size can be measured to correct the contrast imaging error through the standard piece, and it can be calibrated to improve the batch measurement accuracy of key data. The automatic image detector has a friendly human-computer interface and supports multiple selection and learning correction.
