<p>PURPOSE:To make it possible to perform correction even if the position of a singular point in point tracking and the position of an actual singular point are deviated by adding a correcting function and the like for each zone tracking and the point tracking responding to externally inputted correcting commands. CONSTITUTION:The actual positions of singular points P0-P3 as the tracking objects on a steel plate 10 are deviated from the zones Z0-Z3 belonging to a zone line 12b obtained in a host computer 12 and zones belonging to the zone line obtained in a slave computer 13 and their positions, respectively by any abnormality. At this time, an operator inputs a singular-point-position correcting command, which specifies the leading singular point P0 (leading edge of the steel plate 10), by using a keyboard. Then, the position of the singular point P0 is forcibly moved to the position of the measuring 21 fixed point of the zone line in the slave computer 13. Namely, the position of the singular point P0 on the zone line of the computer 13 is corrected. Then, the positions of the other singular points P1-P3 are corrected to the positions corresponding to the distances from the preset singular point P0.</p> |
