Polarization and binocular vision combined three-dimensional reconstruction method

Abstract

The invention provides a polarization and binocular vision combined three-dimensional reconstruction method. Aiming at the complementarity of the characteristics of a polarization three-dimensional reconstruction result and a binocular vision reconstruction result, the azimuth angle error of the polarization reconstruction result is corrected by taking the registered binocular depth data as a reference, so that the problem of concave-convex blurring of polarization reconstruction is solved. And on the premise of assuming a linear relationship, spatial fitting is performed on a polarization initial reconstruction result and the registered binocular depth map, and missing parts of the binocular depth map are complemented by using surface data of polarization reconstruction. A cross iterationthought, a cyclic correction process and a full complementation process are adopted to solve the influence of a data missing problem in a binocular depth map on a reconstruction result. The reconstruction result is high in surface resolution, accurate in shape information and high in object surface detail texture reduction degree, and the final reconstruction result has a relatively real depth.

Description

technical field [0001] The invention belongs to the field of three-dimensional reconstruction of object surfaces, relates to a three-dimensional reconstruction method combining polarization and binocular vision, and is applicable to various resource-limited three-dimensional reconstruction application scenarios. Background technique [0002] Compared with two-dimensional images, three-dimensional data on the surface of objects can provide more comprehensive feature information. Three-dimensional reconstruction technology has been applied in many fields such as surveying and mapping navigation, identification, unmanned systems and cultural relics protection. [0003] As a new type of three-dimensional imaging technology, polarization three-dimensional imaging technology uses the polarization state information of the reflected light on the surface of the object to estimate the three-dimensional depth data of the target object, which can reflect the physical and chemical charact...
