Research on Digital Image Recognition Scheme Based on 3D Technology

Image is a reflection of objective reality in a certain sense, which conveys information to human beings in different modes. As an important information carrier, image is intuitive, rich in content and easy to communicate, which is an important content of multimedia. With the wide application of 3D images, image recognition based on 3D technology has attracted more researchers' attention, and there are more and more recognition methods. Human beings rely on two-dimensional images to perceive the three-dimensional world, and using computers to accomplish the same thing is the main research content in the field of computer vision. At any particular moment, the points on the target in the image correspond one-to-one with the points on the real three-dimensional target object. The images acquired by the imaging system are often not directly applicable due to various conditions and random interference. Based on the three-dimensional technology, this paper studies the digital image recognition scheme, and analyzes the image processing such as grayscale correction and noise filtering.
