Technical principle and application field of automatic image measuring instrument

Today, various industries have a variety of test equipment, such as chemical analyzers, environmental detectors, 3D laser scanners, plotters, length meters, and industrial online and process online controllers. Among them, three coordinate detector, image detector and projector are special length measuring instruments used to measure geometric dimensions and geometric tolerances.

The automatic image Measuring Instrument is a high-precision CCD color lens, continuous zoom objective, color display, video cross line display, precision grating ruler, multi-function data processor, data measurement software and high-precision workbench structure. Optical image measuring instrument. 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), LCD TVs. (LCD), printed circuit board (circuit board, PCB), automobile, medical equipment, watches, screws, springs, instruments, gears, cams, threads, radius templates, thread samples, wires and cables, tools, bearings, screens, test screens, cement screens, templates (steel meshes, SMT templates), etc

With the progress of technology, the image detection market has been basically covered by automatic image detectors. It is a non AI modern optical system based on digital image detector (also called CNC imager). Contact the measuring instrument. It inherits the excellent motion accuracy and motion control performance of digital instruments, and combines the design and flexibility of machine vision software. It belongs to Z's advanced optical dimension testing equipment. Automatic image detector can easily and quickly carry out 3D coordinate scanning measurement and SPC result classification to meet the increasingly prominent requirements of modern manufacturing dimension detection: higher speed, more convenient and more accurate measurement requirements, and solve another problem in the development of manufacturing industry: bottleneck technology. Automatic image detector is an advanced stage of image measurement technology, with high intelligence and automation. Its excellent hardware and software performance makes coordinate dimension measurement convenient and fast. It has automatic learning function based on machine vision and process control. It can take the measurement process, focus and selected path according to the high-speed and accurate micro position of the digital instrument. Point, function switching, manual correction, optical matching and other operations are self-learning and memory. The fully automatic image detector can easily understand the actual operation process of all operators. Combined with automatic focusing and area search, target locking, and edge extraction fuzzy operations, artificial intelligence can be realized, and the deviation caused by workpiece difference and position difference can be automatically corrected to achieve accurate selection and high-precision repeatability. Therefore, the spectrometer spark direct reading operator can get rid of fatigue, frequent selection, repeated walking, accurate visual alignment of function switching and other monotonous operations, as well as increasingly onerous tasks to be tested. The German Brooke spectrometer also improves the workpiece batching efficiency hundreds of times to meet industrial sampling and inspection. Mass testing is required.

The automatic image detector has three methods: manual measurement, CNC scanning measurement and automatic learning measurement. Three modules can be superimposed for composite measurement. It can scan and generate an aerial view image to achieve the full screen target traction of the point and where to go. The measurement results are generated and the image mapping is synchronized with the image mapping. It can automatically click the image to enlarge the full screen Hawkeye. Angiographic imaging errors can be corrected by any standard measurement of any measurement size, and calibrated to improve the accuracy of key data. The fully automatic image detector has a friendly human-computer interface and supports multiple choices and learning correction.

It is important to select the image detector to check whether the image is clear and whether the precision reaches the standard (the general precision selection standard is 1/3~1/8 of the full tolerance of the tolerance zone). The captured image can be transmitted to the data acquisition card of the computer through the data line, and then imaged by the software on the computer monitor. The operator can quickly measure on the computer with the mouse. Some manufacturers of manual image measuring instrument may use domestic products to save costs, and the cost is relatively low, and the effect is slightly poor.
