Summary/Abstract: The paper deals with the quality measurement process using the KEYENCE® industrial monochromatic camera and its calibration to determine the dimensions of the component under quality control process. The threshold value determines the shape of the component and the histogram method determines the number of pixels of the selected analyzed area. After calibrating the camera with a scale and changing the camera's distance to the object, a general equation was obtained from the measured points. Using this equation, it is possible to determine the size of the measured object from pixels. The average relative error of the object’s dimensions was: length - 1.94 % and the width of 100 components was: 1.31 %. In quality control, monochrome cameras can be used to measure product dimensions, along with image processing principles and with other measure methods.
