CCD image automatic measurement software

Performance and features:

The measurement and control of the machine system adopts a high-resolution image device to clearly display the indentation on the computer screen. Through the software to convert the signal, the hardness value of the test indentation is automatically measured. Depth and gradient curve diagrams can be drawn for fixed-point and continuous testing processes. Support WIN9X, WINNT, WIN2000, WINXP and other operating systems. Micro-Vickers, Knoop, carburized layer, etc. can be tested. Hardness values can be automatically converted in various forms. High magnification or low magnification objective lens can be selected according to needs. Image clarity: >540 lines. The image can be adjusted for contrast, brightness, etc. Image files and data files can be opened and stored separately. Printing and other processing. Data files and image files can be viewed at any time, and the data files are printed in the form of tables and curves.

Expertise:

It can be used for continuous test of continuous reading of indentation after continuous loading, and successive experiments of each loading and each reading of indentation can be carried out. The ccd camera and video cable that are convenient for observation are adopted, and the indentation can be directly observed and measured on the monitor, and the measurement accuracy is high with the mouse. For setting test conditions and displaying results, etc., it can be operated and displayed clearly and quickly. Through the measurement software, it is easy to operate with a computer, and realize single-point measurement. Random measurement of multiple points and statistical measurement data can be set arbitrarily. , Statistical measurement data, automatically calculate the penetration layer depth according to the judgment value (such as 550) input by the user. Statistical calculation, conversion, display curve, judgment whether it is qualified, etc. can measure the length and angle of the part and save and print the graphics. It can be used as a small projector use CCD.
