A fast image matching algorithm was proposed to increase the running efficiency of the algorithm
and meet the real-time requirement for some applications. A gray edge image of the template was extracted using Sobel marginal operator. Matching points were sampled from the gray edge image and utilized to reduce the time complexity of the matching process. At the same time
the global searching mechanism of the genetic algorithm was exploited to expedite the convergence of the algorithm to the sub-optimal solution to the problem. Based on it
a precisely locating phase was introduced to fix the location and rotating degree of the optimal target sub-image in the scene image. Practical application of the algorithm to the image matching system of a fully automatic gold wire bonder demonstrated that the algorithm could meet the real-time requirement and the locating precision requirement of the system
and they worked as expected.
