Abstract

At present, the two-dimensional images obtained by existing small lenses cannot effectively reflect the three-dimensional structure, and many surface defects in4 industry have obvious three-dimensional morphological changes[1]. Therefore, three-dimensional small optical systems are the development direction of industrial optical technology[2]. In view of the characteristics of small lens, small aperture, and single imaging channel, this paper uses a monocular stereoscopic vision method to iteratively reconstruct depth information, and designs a stray light elimination optical system that can obtain both traditional images and three-dimensional stereoscopic images. , improved the photometric stereo vision algorithm used in traditional telecentric systems, developed close-range 3D imaging suitable for small lens systems and improved the accuracy of 3D imaging.
