摘要

PRESENTED METHOD AND APPARATUS FOR VIDEO IMAGES CONTACT deformation FLOOR OR A TIRE PRINT tire footprint. It IS GENERATED A digitalized tire tread image as a pixel array. Each pixel is given a binary value of 1 or 0, TO SUBMIT AN IMAGE EVALUATED TRACTION. VALUE IS ATTRIBUTED TO A FIRST CONTACT AREAS WITHIN THE IMAGE WHILE attributed a second value to areas without contact. The image is enlarged and rearranged SEQUENCE IN A PROPER TO ELIMINATE ALL WHITE IMAGE PIXELS AND SURFACE DEFECTS OR DISPOSE OF SIMILAR THAN OF INTEREST IN THE ANALYSIS OF TIRE. THIS FORM IS GENERATED AN IMAGE OF TIRE TREAD ACCURATE IN SIZE AND DIMENSIONS And from that print tire footprint MAY BE DETERMINED THE TOTAL AREA, THE AREA OF CONTACT AND AREA IDLE, AND MAY TAKE MEASURES wIDTH, LENGTH OF THE CENTRAL LINE, AND OTHER LOCATIONS IN SEVERAL desired lengths SIDE wIDTH. This data can be used to analyze tire construction, operation, HIS GENERATION OF NOISE and performance.
