发明名称 Systems and methods for detecting defects in printed solder paste
摘要 A method of analyzing an image of a substance deposited onto a substrate, the image comprising a plurality of pixels, includes defining a region of interest in the image, associating the region of interest with first and second perpendicular axis, wherein a set of pixels in the image lie along the first axis, converting the pixels in the region of interest to a single dimensional array aligned with the first axis and projecting along the second axis, and applying at least one threshold to the single dimensional array, the threshold based at least in part on a predetermined limit.
