Title:
AUTOMATIC EXTRACTING METHOD FOR PATTERN LIGHT IN SHAPE MEASURING ENDOSCOPE
Document Type and Number:
Japanese Patent JPH04145313
Kind Code:
A
Abstract:
PURPOSE:To extract true pattern light even if the pattern light is ruptured by detecting the pattern light with the maximum length in the Y-axis direction, judging it as the true pattern light, judging all the pattern light overlapped with the Y-coordinate on the true pattern light as the false pattern light, and removing it. CONSTITUTION:When an image with halation and rupture is obtained, a black- and-white image is generated. Circumscribed rectangles of regions 1'-6' are generated, and coordinates of end sections in the pattern direction (Y-coordinate) are obtained. Lengths in the Y-axis direction are obtained. The lengths are compared, when the maximum length is detected, this region is judged as the true pattern light, and this pattern light is extracted. Whether it is overlapped on the Y-coordinate of other region or not is retrieved, and the overlapped region is referred as halation and removed.
