  • Patent number: 5164994
    Abstract: A system (82) and method for locating features in an image. In the preferred embodiments, the present invention accepts as input a tilted view X-ray image of a PC board (10), as well as expected locations of solder joints (18) in the PC board (10). The present invention then determines the actual center locations (32) of these solder joints (18) by defining windows within the image and checking individual areas within the window, to see if they fall below a predetermined threshold. In addition, the system (82) determines if these pixels are connected to other pixels that have been previously determined to be part of the solder joint (18). Finally, the system (82) determines the center of the group of pixels determined to be part of the solder joint and displays the coordinate location of this center.
