Video measuring instrument working principle

 

The video measuring instrument is a high-precision high-precision camera composed of a high-resolution CCD color lens, a continuously variable magnification objective lens, a color display, a video cross-hair display, a precision grating ruler, a multi-function data processor, data measurement software and a high-precision workbench structure. Optical image measuring instruments.

The image measuring instrument is based on artificial intelligence technologies such as automatic edge extraction, automatic matching, automatic focusing, measurement synthesis, and image synthesis based on machine vision. Image map target guidance, full field of view eagle eye zoom and other excellent functions. At the same time, based on the automatic focusing process under the precise control of machine vision and micron, it can meet the needs of auxiliary measurement under clear images, and can also add a contact probe to complete coordinate measurement. Excellent software performance that supports spatial coordinate rotation, batch measurement and SPC result classification can be performed when workpieces are placed randomly or using fixtures.

Video measuring machine uses

Image measuring instrument is a high-precision, high-tech measuring instrument that integrates optical, mechanical, electrical, and computer image technologies. It is mainly used to measure two-dimensional dimensions. The items that can be measured by the image measuring instrument are:

1. Multi-point measurement of points, lines, circles, ellipses, ellipses and rectangles to improve measurement accuracy;

2. Combined measurement, center point structure, intersection point structure, line structure, circle structure, angle structure;

3. Coordinate translation and coordinate correction to improve measurement efficiency;

4. Collecting instructions, batch measurement of similar workpieces is more convenient and quick, and the measurement efficiency is improved;

5. The measurement data is directly input into AutoCAD to become a complete engineering drawing;

6. The measurement data can be input into Excel or Word for statistical analysis, a simple Xbar-S control chart can be cut out, and various parameters such as Ca can be calculated;

7. The image measuring instrument can be switched in multiple languages;

8. The automatic image measuring instrument can record user programs, edit instructions, and teach execution;

9. Large map navigation function, special 3D rotating lamp for knife mold, 3D scanning system, fast auto focus, auto zoom lens;

10. Contact probe measurements are available for purchase. The software can freely realize probe/image conversion for contact measurement of irregular products, such as ellipse, radian, flatness and other dimensions; it can also be directly imported into reverse engineering software for further processing with the probe!

11. The image measuring instrument can also detect the roundness, straightness and radian of circular objects;

12. Flatness detection: The flatness of the workpiece is detected by a laser probe;

13. Professional gear measurement function;

14. Special measurement functions for test sieves used by major metrology institutes across the country;

15. The automatic image measuring instrument has the function of comparing drawings and measured data.

Optical measuring device application fields 

The image measuring instrument is suitable for all application fields for the purpose of two-coordinate measurement, and is widely used in machinery, electronics, aerospace, molds, springs, gears, terminals, circuit board contacts, hardware and plastics, magnetic materials, electronic circuits, components, Measurement of watches, hardware stamping industry, ore industry, mobile phone accessories, home appliances, connectors, mechanical accessories, precision fixtures, plastics, hardware, computer peripheral industries, etc.

Optical measurement equipment accuracy

Accuracy is the fundamental of measuring instruments, and it is one of the very important indicators for users to choose instruments. The measurement accuracy of the image measuring instrument mainly depends on the quality of the image measuring head, the performance of the illumination light source system, the movement of the instrument and the positioning accuracy, and the quality and level of the software and hardware of the data processing and measurement are also extremely important factors. As an automated measuring instrument, the measurement efficiency of the video measuring instrument is one of the most important factors for customers. High measurement efficiency can reduce equipment investment, improve production efficiency, and reduce labor costs.

The two-dimensional image measuring instrument used for on-site measurement in the factory usually has a resolution of 0.001mm and a measurement accuracy of about (3+L/200) μm. The two-dimensional image measuring instrument used in high-precision measurement fields such as precision measurement and value transfer, the measurement accuracy is generally better than (1.0+L/300) um.
