摘要： A work transportation line includes a work handling apparatus which has an operation that is automatically changed in response to alteration of a work type, from one type to another, so as to be suitable for a work type to which a subject work is altered. An indication of a work type alteration is provided as a result of a comparison between specified attributes of a subject work, which are extracted from a two-valued image of the subject work, and predetermined reference attributes for various work types.

摘要： A method is used for discerning a specific type of a work, including a plurality of specified contoured portions forming parts of the work, from an image including the subject work. Each specified contoured portion, which may be defined by geometric characteristics, such as an area, a peripheral length of a specified contoured portion and a ratio between the area and peripheral length, is recognized in the image based on two-valued image data into which many-valued image data representative of the subject work is transformed with a threshold value. A position of the subject work is discerned based on a relative position of each two specified contoured portions defined by geometric characteristics, such as a distance between centers of each two specified contoured portions and an angle of a center line of each two specified contoured portions relative to a center line of another two specified contoured portions.
