The purpose of pixel correction is to enable the computer to obtain the ratio between the pixels of the object measured by the vision measuring machine and the actual size. There are a lot of customers do not know how to carry out pixel correction of vision measuring machine, next Handing and share with you the method of pixel correction of vision measuring machine.
The definition of pixel correction: it is to determine the corresponding relationship between the pixel size of the display screen and the actual size.

Necessity of pixel correction:
① After installing the software, the pixel must be corrected before the first measurement, otherwise the result measured by the vision measuring machine will be wrong.
Each magnification of the lens corresponds to a pixel correction result, so a pre-pixel correction must be performed for each used magnification.
(3) After the camera component of the visual measuring machine (such as CCD or lens) is replaced or removed, the pixel correction must also be re-performed.

Pixel correction mode:
(1) Four-circle correction: The way to move the same standard circle to the four quadrants of the crosshair in the image area is called four-circle correction.
Single circle correction: The way to move a standard circle to the center of the screen in the image area for correction is called single circle correction.

Pixel correction operation method:
Manual calibration: When correcting, manually move the standard circle and manually seek the edge, which is usually used for manual visual measuring machines.
Automatic calibration: When correcting, the standard circle is automatically moved and the edge is automatically sought, which is usually used for automatic visual measuring machines.

Pixel correction benchmark:
Please use the glass correction sheet we provide for pixel correction.
