Single lens structured light stereo imaging device and method for realizing stereo imaging of scenes in pipeline

Abstract

The invention discloses a single lens structured light stereo imaging device. The single lens structured light stereo imaging device comprises a camera, a semi-permeable mirror and an optical grating projector, wherein the camera carries out image acquisition on the inner wall of a pipeline through the semi-permeable mirror, the semi-permeable mirror transmits structural optical gratings projected by the optical grating projector to the inner wall of the pipeline through reflection, and the camera and the optical grating projector are respectively controlled, so that the structural optical gratings appear on the inner wall of the pipeline alternatively, and further the camera obtains images without the structural optical gratings and images with overlapped structural optical gratings alternatively. The invention further discloses a method for realizing stereo imaging of scenes in the pipeline. In the whole camera shooting process, single lens camera shooting and the structural optical gratings are combined to carry out image gridding, and the position coordinates of the camera are adjusted to shoot a series of images. Imaging of the inner wall of the pipeline is achieved by adopting an imaging method combining the single lens camera and the structural optical gratings, the shape variation of the surface of the inner wall of the pipeline is reflected according to the variation situations of light modes, and image acquisition of the scenes in the pipeline is simplified.

AI Technical Summary

Problems solved by technology

The three-dimensional measurement technology of structured light is becoming more and more mature, but because of its high-precision mechanical drive device, the cost is greatly increased, which brings certain difficulties to popularization and application

However, in the actual shooting process of the existing three-dimensional measurement stereo imaging method, two cameras need to be synchronized when zooming, changing the aperture, and changing the position, which is also a difficult problem in technical implementation.

The existing three-dimensional measurement stereoscopic imaging device and imaging method are not ideal enough, and cannot be widely used in the measurement process of the inner wall of the pipeline in the fields of industry and medicine, and cannot be more effectively adapted to social needs
