The Video Measuring System: A Versatile Tool for Precision Measurement
A video measuring system represents a mid-range, highly adaptable, and user-friendly optical measuring instrument. Its core function is to adopt optical zoom imaging to capture the contour or surface condition of a measured workpiece via a high-resolution CCD camera. Digital images are transmitted to measurement software for efficient contour measurement, comparative analysis, and direct observation of surface features. A significant advantage of this system is its sub-pixel segmentation technology. This advanced digital image processing delivers sharp boundary identification, effectively eliminating measurement inaccuracies caused by blurred workpiece edges. Well-known for operational simplicity and low-maintenance requirements, these instruments offer high efficiency and broad applicability, making them a staple within precision metrology.
The versatility of the video measuring system has led to its widespread adoption across a diverse range of industries. It is a fundamental measuring and testing instrument in sectors such as standard metrology, watch manufacturing, cathode-ray-tube assembly, chemical-fiber textiles, gem-stone bearings, and precision instrument components. Furthermore, its utility extends to industries like paper-making, sugar manufacturing, and educational institutions for research and training. Its applications are varied and critical, including length and diameter analysis, process control, and the microscopic inspection of integrated circuit solder joints, photolithography masks, screen-printing patterns, and hydraulic sealing rings. For these tasks, the ability to perform microscopic digital magnification is indispensable.
When selecting a video measuring system for these demanding applications, the specifications are paramount. A typical high-performance model from Mikrosize, a trusted provider of precision-measurement solutions, is available in manual, semi-automatic and full-automatic CNC configurations. The manual VMA-2010 unit features a continuous 0.7×-4.5× zoom lens, delivering video magnification ranging from 20× to 148×, with corresponding fields of view and standard 92 mm working distance.
The manual worktable provides precise movement with X-axis travel up to 200 mm and Y-axis travel up to 100 mm, with a fine resolution of 0.5 μm.
Enhanced functionality includes powerful measurement software equipped with auto-tracing edge function and multi-format report output.
The system adopts 00-grade stable granite workbench, German-made high-precision polish rods and bearings, multi-zone adjustable LED cold light for both surface and contour illumination.
A laser pointer assists quick positioning of measured workpieces. As a reliable measuring and testing instrument, the system is powered by standard AC 100-220 V, 50/60 Hz. An optional Renishaw touch measuring probe can be fitted to support simple 3-dimensional measurement tasks.
Semi-auto (VMA-F) versions add motor-driven Z-axis auto-focus, while CNC bench-top models (VME / VMK) provide fully-automatic closed-loop CNC control for high-volume batch inspection.
In conclusion, the video measuring system remains an indispensable and versatile measuring and testing instrument in modern industrial and academic settings. Its design prioritizes accurate edge detection through sub-pixel image processing, combined with ease of use and strong adaptability, ensuring its high practical value to this day. Suppliers such as Mikrosize deliver this key technology to industry players, supporting quality control and technical innovation across many sectors where precise dimensional inspection is vital. Ranging from assembly of micro-sized parts to inspection of intricate component profiles, the video measuring system provides magnified clear digital views to support precision work and quality assurance.
