A detecting and error-correcting method capable of rapidly and accurately obtaining an element center and a deflection angle is disclosed. Interested edge area can be rapidly and accurately found out through an automatic edge area extraction method based on combination of binary morphology and image reduction, and subsequent edge extraction image scope is minimized as possible. Pixel level edge is roughly positioned at first, and accordingly a sub-pixel edge is rapidly extracted by one-dimensional curve fitting method. The method overcomes the defect of complex algorithm of a conventional sub-pixel edge extraction algorithm based on two-dimensional images, and the time of extracting accurate sub-pixel edge can be shortened. Weighted least square rectangular edge fitting algorithm based on linear hazen paradigm can detect straight lines on any positions of an image, and effectively minimizes influence of outlier on fitting precision due to uneven edges. The central positions of a plurality of elements and deflect angles can be rapidly and accurately detected at once, and the efficiency of visual detection is improved.

A method and apparatus for imaging an overlying conductive pattern over an underlying conductive pattern on a substrate, by determining deviations between the actual locations and the nominal locations of predetermined reference targets in the underlying conductive pattern on the substrate; and utilizing the determined deviations for modifying the scanning control data used for imaging the image data of the overlying conductive pattern in order to reduce misregistration thereof with respect to the underlying conductive pattern. Preferably, the reference targets are predetermined connection sites in the underlying conductive pattern to be precisely located with respect to connection sites in the overlying conductive pattern. The reference features may be assigned different weights according to their registration importance, and the deviations may be determined according to a threshold which varies with the weight assigned to the respective reference feature.

The device has printed circuit boards mounted on respective tables, and a control unit controlling an X-axis drive section and a Y-axis drive section to move an X-direction axle and Y-direction axle in a direction. The axles are positioned in processing positions by the X-axis drive section and a Y-axis drive section. The axes are determined such that drills are put into a printed circuit board by a Z-axis drive section to drill holes. The z-axis drive section moves a spindle into corresponding z-direction. An independent claim is also included for a method for drilling a printed circuit board processing device.
