Abstract
A method of inspecting a bottle (14) having a threaded section (104) for thread defects as the bottle moves along a production line (10) requires video images (100) of the bottle to be taken as the bottle moves into the fields of view of video cameras (22). Each video image encompasses a general region of interest (108) which contains at least a portion of the threaded section of the bottle. The position of the bottle (14) within the video image is then determined based on the location of the top rim (110) of the bottle within the video image. A portion of the general region of interest which encompasses at least a portion of the threaded section of the bottle is segmented into a plurality of specific regions of interest (120, 122). Pixels of the video image within the specific regions of interest are then examined to detect thread defects.
