Abstract

The invention relates to the technical field of computer vision. Embodiments of the present invention provide a method and system for acquiring a depth image based on speckle structured light, wherein the method includes: acquiring a speckle reference image and a speckle scene image, wherein the speckle reference image is related to a preset reference plane, And the speckle scene image is related to the target object plane; respectively perform ellipse LBP feature extraction on the acquired speckle reference image and speckle scene image to obtain the corresponding first feature texture image and second feature texture image; based on the first A feature texture image and the second feature texture image, performing stereo matching between the speckle reference image and the speckle scene image to output a corresponding parallax image; and optimizing the parallax image and combining the internal parameter to determine the corresponding depth image. In this way, the influence of noise and light is avoided, and the overall effect of the obtained depth image is improved.

Description

technical field [0001] The present invention relates to the technical field of computer vision, in particular to a depth image acquisition method and system based on speckle structured light. Background technique [0002] With the continuous development of science and technology, stereo matching (Stereo Matching), as a key technology in 3D reconstruction, non-contact distance measurement and visual navigation, is widely used in the fields of automated assembly line, unmanned driving and intelligent robot control. [0003] However, in the process of image stereo matching, due to the influence of noise, brightness, contrast, specular reflection and low texture, etc., when the image is subjected to stereo matching, there will be many problems such as mismatching or discontinuous matching scene information. It will directly affect the quality of the 3D reconstruction of the later image. [0004] Therefore, how to obtain a depth image with a better effect through stereo vision m...
