The paper proposed a novel fast identification method of hand contour for contour matching and its movement. This system used an improved ant colony clustering algorithm to get hand center quickly, established relevant rendering system, and registered the virtual object. Meanwhile, for personalized applications, the paper proposed fast Harris palmprint identification algorithm applied in augmented reality. Experiments show that the new algorithm has good recognition precision and real-time tracking performance, and can adapt to the application requirements of augmenting reality systems.
