Title:
METHOD FOR FORMING MASTER DATA FOR INSPECTING PROTRUDING AND RECESSED FIGURE
Document Type and Number:
WIPO Patent Application WO/2007/000909
Kind Code:
A1
Abstract:
A method for forming master data for inspecting a protruding and recessed figure
in which correct master data can be formed in the absence of non-uniformity. A
figure is selected from a CAD drawing of a tire and the image of each figure is clipped,
a position for arranging the figure is set by the radial distance from the center
of a tire and the displacement angle in the circumferential direction of the tire
from a specified position, and then the height of each region of a clipped image
is set. Subsequently, the clipped image is transformed into a gray scale image
depending on the height by using the height information of each region, the gray
scale-based image is sampled at a predetermined interval in the radial direction
from the center of the tire at the arranging position of the figure and sampled
at a predetermined angular interval in the circumferential direction of the
tire, and then it is transformed such that the intersecting points are spaced
apart equally, thus forming master data.
