Abstract
A system for inspecting the surface of elongated work boards being moved, which is featured in that the work boards are photographed using a digital camera, that line image data which intersect with a moving direction of the work boards are extracted, and that the resultant line image data are integrated and synthesized to obtain a synthesized image, which is then displayed to evaluate the worked state of the work boards.
Claims5
A surface inspection system for work boards, comprising:
- a digital camera for photographing at least one elongated work board;
- image data-extracting means for extracting line image data on a sampling line intersecting with a moving direction of the at least one elongated work board from an output of said digital camera;
- and
- image data-synthesizing means for integrating and synthesizing the line image data being output from said image data-extracting means, wherein said image data-extracting means is designed to take, as the sampling line thereof, a line which passes through an intersection point between a pair of diagonal lines in a photographing zone of said digital camera and intersects with a longitudinal direction of movement of the at least one elongated work board in a substantially orthogonal manner.
