INFORMATION-MEASURING SYSTEM FOR DIAGNOSTICS OF THE TECHNICAL CONDITION OF VIBRATION-LOADED OBJECTS BASED ON THE ANALYSIS OF THE IMAGE BLUR OF THE MARK

Abstract

Background. The necessity of creating diagnostic systems for vibration-loaded objects is shown. It is noted that non-contact systems have sufficient capabilities to determine the vibration amplitude. It is shown that the analysis of image sequences from the camera makes it possible to estimate the vibration parameters. Materials and methods. Mechanisms for analyzing the image from the camera by counting lines and pixels when measuring the radius of the image of a round mark are proposed. Numerical modeling of the processes of measuring the radius of the image of a round mark using technologies for counting lines and pixels with different parameters was carried out. Result. Simulations have shown that the accuracy gain of applying the pixel counting technology to the line counting technology will increase as the label image radius increases. Conclusion. It is predicted that the maximum absolute error in measuring the radius of the mark image using the pixel counting technology will decrease with an increase in the radius of the mark image.
