Abstract: 3D images are widely used in our lives, and the tech of 3D images processing is what people look for. Therefore, algorithm about registration of 3D images comes in sight. And different three-dimensional image matching technology has its own advantages and disadvantages corresponding to different application fields and use methods. This paper introduces some main important ways of 3D images matching and look ahead to its future.

Key words: 3D images, image matching, ICP, feature point
