Abstract

The invention discloses a monocular vision three-dimensional reconstruction ranging method based on polarization multi-spectrum, comprising the following steps: Step 1, building a monocular camera imaging system; Step 2, multi-spectral polarization processing and polarization information acquisition; Step 3, features Extraction and stereo matching; Step 4, 3D point cloud structure reconstruction; Step 5, using similar triangle principle for distance measurement; Step 6, screening distance data. The monocular vision ranging method proposed by the present invention can effectively reduce the difficulty of equipment operation without compromising the measurement accuracy. In view of the fact that feature extraction is difficult to extract non-textured objects and highlights produce data holes, the method of multi-spectral polarization imaging is used to obtain multi-spectral Stokes parameters for each pixel, which improves the efficiency and accuracy of feature extraction and stereo matching.

Description

technical field [0001] The invention relates to the technical field of three-dimensional reconstruction, and in particular to a method for measuring ranges based on polarization multispectral three-dimensional reconstruction of monocular vision. Background technique [0002] Computer vision technology is a technology that replaces the human visual physiological system with a system composed of a camera and a computer. It can perform operations such as identification, tracking, and measurement of targets, and can further process images. The image is more in line with the visual imaging effect of the biological vision system, and is more conducive to meeting the needs of the computer vision system. Three-dimensional reconstruction is becoming more and more important in computer vision. Computers use computer digital image processing technology, computer vision, machine learning, image processing and pattern recognition to realize three-dimensional information processing capabi...
