Abstract
A system and method for high-speed alignment of components is provided. During training time of a machine vision system, a small subset of alignment significant blobs along with a quantum of geometric analysis for picking granularity is determined. By utilizing only the alignment significant blobs and the geometric analysis, the use of conventional alignment techniques may achieve significantly better speed and robustness for component alignment. In operation, during training time, grayscale blobs are extracted using a scale space search. Alignment significant blobs are then determined from the grayscale blobs. Once alignment significant blobs are determined, run time smoothing and down sampling are then determined on the alignment significant blobs. The machine vision system is then trained to operate with the alignment significant regions.
