Summary: | A method and device for quantifying a wear level of a bristle field of a brush are disclosed comprising a plurality of bristle tufts grouping each a plurality of single bristles, said bristle tufts being distributed over the bristle field, the method comprising the following steps:
- recording and storing an image of the bristle field;
- converting the image into a gray scale image by use of digital image processing and storing the gray scale image;
- converting the gray scale image to at least one binarized image with only two tone values by use of digital image processing, thereby assigning one tone value to bristles and/or bristle tufts visible in the image and the other tone value to the background in the image not showing bristles or bristle tufts, and storing the binarized image;
- applying at least one evaluation methods;
- comparing the results of the at least one applied evaluation method with reference data of an unused brush and/or of used brushes with determined wear levels to classify the wear level of the bristle field. |
