Abstract:
An image processing method for examining images of a plurality of objects obtained by an industrial visual sensor the plurality of objects being articles which are processed industrially, comprising:detecting a plurality of image data by an image input device of said plurality of objects on a production line at a current time; loading a frame memory with said plurality of current image data; processing the image data in accordance with a processing program; reading the plurality of current image data from the frame memory; annexing identification data to the read plurality of current image data in according with said processing program to produce a plurality of identified image data; successively transferring the plurality of identified image data from the frame memory to an auxiliary storage device and storing said transferred plurality of identified image data in the auxiliary storage device as a plurality of past image data; subsequently transferring past image identified as corresponding to unsuccessful detection and stored in the auxiliary storage device from the auxiliary storage device to the frame memory; selectively executing preprocessing on, and processing by the processing program, the past image data corresponding to the unsuccessfully detected images transferred to the frame memory; displaying a result of the selective preprocessing and the processing of the past image data corresponding to the unsuccessfully detected images on a monitor; and examining by an operator on the monitor the past image data to determine a cause of failure of object detection.
