摘要:
A component presence/absence judging apparatus judges the presence/absence of components through a registration step and an inspection step. The registration step includes an ante-mounting feature acquisition step, a post-mounting feature acquisition step and a classifier configuration step. At the ante-mounting and post-mounting feature acquisition steps, ante-mounting features and post-mounting features are respectively acquired from an ante-mounting image and a post-mounting image taken at each of predetermined places on an ante-mounting board and a post-mounting board. At the classifier configuration step, a classifier is configured by registering the ante-mounting features and the post-mounting features as training data to a support vector machine. Then, at the inspection step, the presence/absence of a component at each of the predetermined places on each post-mounting operation board to be inspected is judged by inputting post-mounting operation features acquired from each of the predetermined places on each post-mounting operation board to the support vector machine configured as the classifier.
摘要:
An image display apparatus including a first storage means for storing at least one item of image data, correction condition data for correcting the image data, and corrected image data obtained after the image data is corrected on the basis of the correction condition data; an image processing means for producing the corrected image data; a display means comprising a screen for superimposing an original image based on the image data and a corrected image based on the corrected image data onto each other and displaying either the original image or the corrected image; an input means for selecting an image to be displayed on the display screen, and a display control means for switching between the images in response to an input from the input means, so that either the original image or the corrected image is displayed on the display screen.
摘要:
A component presence/absence judging apparatus judges the presence/absence of a component through a registration step and an inspection step. The registration step comprises an ante-mounting color information acquisition step, a post-mounting color information acquisition step and an inspection area determination step. Ante-mounting color information is acquired from an ante-mounting image taken at a predetermined portion on an ante-mounting board. Post-mounting color information is acquired from a post-mounting image taken at the predetermined portion on a post-mounting board. Then, a section having a large difference between both color information of the ante-mounting image and the post-mounting image is identified and is determined as an inspection area. At the inspection step, the presence/absence of the component at a predetermined place on each inspection board to be inspected is judged in dependence on the color information on the determined inspection area.
