TIRE SURFACE IMAGE DISPLAY METHOD, AND IMAGE PROCESSING DEVICE EMPLOYED FOR IMAGE DISPLAY THEREOF

A method for displaying an image of a surface of a tire includes: taking an image of a surface of a tire formed with a mark having a protrusion and a recess; acquiring waveform data from the taken image of the surface; creating a histogram from the waveform data; determining, based on the histogram,...

Summary:A method for displaying an image of a surface of a tire includes: taking an image of a surface of a tire formed with a mark having a protrusion and a recess; acquiring waveform data from the taken image of the surface; creating a histogram from the waveform data; determining, based on the histogram, a first bin threshold to distinguish a surface luminance of the protrusion of the mark, and a second bin threshold to distinguish a surface luminance of the recess of the mark; and displaying the image of the surface of the tire including the mark on a screen by representing a region equal to or higher than the first bin threshold, a region lower than the first bin threshold and higher than the second bin threshold, and a region equal to or lower than the second bin threshold in the histogram in three attributes of color.
