A UAV image matching method based Baby Toys on RANSAC (Random Sample Consensus) algorithm and SURF (speeded up robust features) algorithm is proposed.The SURF algorithm is integrated with fast operation and good rotation invariance, scale invariance and illumination.The brightness is invariant and the robustness is good.The RANSAC algorithm can eff
