Abstract
An image processing method for improving the reliability of an industrial visual sensor, in which image data picked up by a camera of the visual sensor are marked with flags such as data for specifying the image data or a detected value for the image data, program name, calibration data, correction data, etc., and are stored in an auxiliary storage device. After a production line is stopped, the image data having so far been stored in the auxiliary storage device are successively invoked to a frame memory of the visual sensor in accordance with the flags. An image processing program is reproductively executed for the invoked image data. Then, established teaching data are checked for reliability, and the cause of a failure in image data detection, if any, is examined, with reference to the information displayed on a monitor screen.
